How does strenuous exercise affect your pulse rate and breathing?
GCSE Science Coursework My aim for the coursework is to do 12 minute running to see my pulse rate and also breathing rate. I will be checking how the exercise affects your pulse rate and breathing. After each exercise I will check how long it takes to recover. For this investigation I would do exercises to get more accurate results. I know my practical is safe because I would not do things that would affect people and also I would not do dangerous activities. Before I do the exercise I must check there is nothing in front of me e.g.: glass and also to be careful by stretching my muscles which would affect the exercise. I would need to use a stopwatch to check my pulse rate and also a pen and paper to write down my pulse rate. I will make my practical a fair test by testing the pulse rate at a certain amount of same time on exercises and also to make sure I would do it in the same place e.g.: park will keep all these things the same by checking my pulse rate at the same time after each exercise. I would also check my pulse rate at a certain time for each exercise and also to try and do it in the same place. I will change this 4 times. The range that I would be using is running, seat ups, walking, and also seating. I would be doing this to see how my pulse rate changes during the exercise and after. I will be making 4 measurements or observations I have chosen the measurements
Comrades And Episodes.
Comrades And Episodes. "Granddad why are you in a wheel chair" said Mr Gates grandson. "I was lucky to still be alive today if it wasn't for three of my comrades in the war," he started to explain. "Please can you tell me Granddad?" the boy asked. "Well it all started many years ago..." Many years ago in the war It was a cold and windy night. I could only just feel my feet through the tight, but thin leather on my boots. My heart was pounding, as I walked across no mans land, the wind suddenly caught up. I thought about my family, as I approached the barbed wire. I gazed into the distance and saw, to my dismay I metallic object. I then saw a flash, and heard a bullet fly past my head, I dropped to the floor as the second hit me in the leg. I felt the bone snap and jolt back through my flesh, the blood oozed out. I tried to move it; I was just trying in vein, as I knew that I would never be able to use it again. I tear ran down my cheek, not in pain, but the fact that I thought, I would never see my family again. I pushed down on my leg as hard as I could, the blood just would not stop. I suddenly herd voices I recognized them as Timmins, Jones and Bard. I heard them talk about ex-lovers and the sort. I thought about their tunics that did not fit, and there faces that I thought I would never see again. I then thought to myself, I am only a hundred yards away I can make
Describe The Journey Of The Components Of The Blood From The Bone Marrow To Their Final Resting Place.
Sheena Shah Describe The Journey Of The Components Of The Blood From The Bone Marrow To Their Final Resting Place. The heart is the organ that pumps blood around the body and never stops beating. Blood has four main components, red blood cells, white blood cells, platlets and plasma, which travel around the body. Blood cells originate from the stem cells in the bone marrow found in cavities within the flat bones such as the ribs and breastbone, by the process of haemopoieses. It then produces the lymphocytes, platlets and leucocytes. Blood travels through the body in double circulation. The first part is pulmonary circulation, where it flows from the heart to the lungs. The second part is called systemic circulation, where blood flows from the heart to the rest of the body. The heart has four chambers. The right hand side of the heart receives deoxygenated blood from the body and pumps it to the lungs. At the lungs, the blood gains oxygen, but loses pressure. The left hand side of the heart receives oxygenated blood from the lungs and gives it a boost so it can reach the other body parts. (A New Introduction To Biology, page 102) Blood is pumped through the pulmonary artery from the heart to the lungs at high pressure. Arteries walls are tough and can recoil, which allow it to travel at high speeds. Arteries branch out into smaller arterioles and then into
The Process of Human Digestion
The Process of Human Digestion Digestive System, series of organs put together that purpose is to break down, or digest, the food we eat. Food is made up of large things called, complex molecules, which the digestive system breaks down into smaller things called simple molecules that get absorbed into the bloodstream. The bloodstream is our blood. The simple molecules travel through the bloodstream to all of the parts of the body, which we use for growth, repair, and energy. All living things that eat to get energy have a digestive system, a feature that makes us different from plants. Plants make their own food in a process called photosynthesis, photosynthesis is when plants make sunlight to convert water and carbon dioxide into simple sugars. But animals, including humans, must take in food in the form of organic matter, such as plants or other animals. Digestion generally involves two parts: a mechanical part and a chemical part. In the mechanical part, teeth physically break down large pieces of food into smaller pieces. In the chemical part, digestive chemicals called enzymes break apart individual molecules of food to yield molecules that can be absorbed and distributed throughout the body. These enzymes are secreted by glands in the body. The digestive system of most animals consists mainly of a long, tube called the alimentary canal, or digestive tract. This canal

Describe how the mechanism of ventilation is controlled.Describe the roles of the phrenic nerves and medulla in generating a basic breathing rhythm. Introduction The tidal flow of air into and out of the lungs is caused by differences in pressure between the thorax and the atmosphere.Air always moves from an area of higher pressure to an area of lower pressure.A ventilation mechanism ensures that a constant supply of fresh air is available to provide enough oxygen for gas exchange and to remove carbon dioxide. There are two processes of breathing- inhalation and exhalation Inhalation Air moves from high to low pressure.Hence the pressure in the lungs is low.The diaphragm muscle contracts and flattens.The external intercostals muscles contract and pull the rib cage out and up.The volume in the lung increases.This reduces the pressure in the lungs and air moves from the atmosphere(high pressure) to the lungs(low pressure) Process of breathing in Exhalation In this process the pressure in the lungs must be higher than the pressure in the atmosphere so that air move in an opposite direction to that in inspiration.The diaphragm muscle relaxes and rises up.The internal intercostals muscles contract and the ribs are pulled downwards and inwards.These movements reduced the volume of the lungs.Since the volume decreases ,pressure increases.Hence air moves out of the lungs to
To find out what is happening to our body after the vigorous training. And what is different before the exercise and later after few attempts? We are looking the pulse rate per minute.
To find out what is happening to our body after the vigorous training! And what is different before the exercise and later after few attempts? We are looking the pulse rate per minute. I have to prove in my experiment what happens after the vigorous. (When our body beats up e.g. heart or after the sport) By doing this I have been selected with a partner to work out experiment. When you go for jog you starting to lose the energy, which provide from the food, the more we jog the more we lose the energy! Energy can be lose in varieties of ways such as biking, playing, breathing in and out etc... I have find out that whether is that true that our blood provides all the organs of our body with the materials needed to stay alive and healthy. Blood flows around our body through network of blood vessels, which makes up our circulatory system. Our blood is kept flowing around this system by the action of our heart. I can find these things by searching main purposes, which are heart beater and blood beater in our hands or nick. We have count how many times does our heart beats per minute before the jog and after, we have to do at least three times to show whether is it true or false but we not exactly sure and we not allow to guess it or give our opinion it got to be actual facts. When we did the experiment about three times then we have divide it by three, which will give us the
Comparison of Two Short Stories -"A Confession Found In A Prison" and "The Tell-Tale Heart".
Tom Chaloner 11P Comparison of Two Short Stories-"A Confession Found In A Prison" and "The Tell-Tale Heart" I am looking at two short stories called 'A Confession Found in a Prison' and 'The Tell-Tale Heart'. Both are murder stories and there are similarities as well as differences in the plot, characters and style of writing. Both stories are told in first person, from the point of view of the murderer but their behaviour and attitude to their bad deeds is very different. In 'A Confession' he says, "Starting, like the guilty wretch I was" which shows that the murderer feels guilt for what he has done. Whereas the murderer in 'The Tell-Tale Heart' is proud of what he has done, there is no evidence of guilt, "I could hardly contain my feelings of triumph", and, "I then smiled gaily". This is evidence of the different feelings towards the murder from each culprit. The Tell-Tale Heart's murderer is triumphant and pleased with the way that he carried out the deed, he boasts of the murder very proudly. The murderer in A Confession is riddled with self-hatred and shame; he is full of guilt and doesn't protest against his sentencing in any way. 'The Tell-Tale Heart' is written as if the murderer is having a conversation and he wants to convince himself he is not mad, yet many signs of madness are displayed throughout the story. He is almost arguing with himself
Does listening to music affect your heart rate?
Does listening to music affect your heart rate? Introduction: The pulse is an indirect sign of blood pressure and heart beating, which is controlled by autonomic nervous system. Cardiovascular and endocrine responses to musical perception which have been studied largely show different changes depending on the situation of the subject (musical experience, handedness, gender, age) and the type of musical stimulus (sedative, harmony music or rhythmic rock music detailing in simple musical elements like intervals, chords, pitch, timbre; or complex musical structures). In a trial, the heart rate was found to decrease after listening to classical and New Age music but not to change after listening to popular music. The heart rate was found to increase if the music contains a fast beat or slow down if the music encourages physical and mental relaxation. Although changes of heart rate and blood pressure as related to listening to music have been reported by many investigators, the complicated problem is still obscure and need deep investigation to clarify its mechanism. Aim: To study and find out if music actually affects our heart rate and if so how? I will also attempt to see if the heart rate changes whilst listening to different types of music at different volumes. Prediction: I predict that listening to music should actually increase/speed up the heart rate as more
Myocardial infarction
Case Study 2006 Myocardial Infarction Sharon Thomas Waitakere Hospital Abstract Of This Case Study Have you ever wanted to know what a Myocardial Infarction is and what its all about. Read on and find out through my eyes, about a patient I was caring for - what happened to him in both his body and mind. The following will show what a Myocardial Infarction ( MI ) is, what happens in the patients body and what care is involved by the medical and nursing teams. All of this to ensure my patient would walk out of hospital and again feel like productive member of society that he most certainly was before his cardiac event. Also within the body of this case study will be evidence based articles to support statements made. Congruent to this, will be reflection on how all that transpired with this man affected me and how my nursing practice has developed because of it. This patients health related journey and the anonymous intimacy that took place, came to a happy conclusion for both nurse and patient. Judith Christiansen's Nursing Partnership Model was published in 1990 and was developed in response to the knowledge gaps in the nursing system in New Zealand ( Taylor, 1995 ). This partnership model is a theoretical framework for nursing practice. It has 3 major concepts - these being nursing partnership, the passage and the context. Anonymous Intimacy is one of 3

During pregnancy the embryo, consisting of a small number of identical cells, undergoes a series of changes which results in the production of a body consisting of specialized tissues and cells. Describe the changes which occur during this process and briefly discuss how the process is controlled: In my essay I am going to discuss how the cells develop at different stages of change, cleavage, gastrulation and implantation then I am going to discuss the formation of a variety of organs and go into detail with one. Fertilization and Cleavage 24 hours post fertilization the zygote, formed by fusion of the two haploid gametes (sperm and ovum) undergoes mitotic division. After fertilization of the egg, cleavage gives rise to 2 cells, 4 cells, 8 cells, 16 cells and 32 cells. At this stage the embryo consists of similar cells. Then subdivision occurs into the inner cell mass and the trophoblast giving rise to cells destined to form the embryo and the extra-embryonic tissues. It takes around a week for these cleavages to occur and for the embryo to move down the Fallopian tube into the uterus, where it will implant in the wall of the uterus. At about the time of implantation the inner cell mass becomes subdivided into two tissue layers and the embryo forms a disc. Gastrulation Is the fourth phase of development. During this phase, cells from the surface of the blastula
