Cardiovascular and Respiratory Systems

Unit 5. Body In Action. Assignment- Task 2. Cardiovascular and Respiratory Systems. The structure and Function of the Cardiovascular System. The Cardiovascular system consists of the heart, blood vessels and blood. Oxygen and waste products are carried to and from the tissues and cells of blood. The heart is the mechanism, which allows this by pumping blood around the body through tubes called veins and arteries. The heart pumps continually throughout a person's lifetime to the tune of around 30 million beats per year, that about 2.5 billion in a lifetime, and even when you are asleep it pumps approximately 10 litres of blood a minute through the 60,000 miles of blood vessels which makeup the transport system of the body. The cardiovascular system is one of the most important of all the body systems. The Heart. The heart is about the size of a clenched fist and is located in the chest between the lungs with its apex slightly tilted to the left. It is made up of Cardiac muscle and is surrounded by pericardium, which is a fluid filled bag, which reduces friction when the heart beats. The heart is not really heart shaped at all but actually cone shaped. ...read more.


They secrete serotonin, which restricts blood flow to damaged parts of the body, and they also stick together at the site of an injury, to plug gaps in broken blood vessels. They activate proteins found in blood plasma which then create a basket like structure which captures red blood cells forming a natural wound covering called a scab. The scab prevents foreign particles entering the bloodstream and stays in place until the tissue underneath is repaired, after it falls off. Short Term and Long Term effects on the Cardio and Respiratory System with running. Short Term effects. Short Term effects of the respiratory system would be you breathe heavier and faster, this is because the sympathetic nerves stimulate the respiratory muscles to make you breathe faster. Short Term effects of the cardiovascular system would be, your heart beats faster during running so that it can pump more blood to the muscles. Your muscles may feel "tired", due to the muscles are working to accelerate your body and keep it moving. Long Term Effects. Long Term effects on the cardio system would be increased heart rate, which would make the cardio stronger and your body would become fitter, increases your stamina. A lowering of resting heart rate, increased cardiac output, the heart size increases and blood can be pumped around the body much more easier. ...read more.


The best thing about swimming is that the heart becomes more powerful and the lungs capacity increases. Swimming is one of the best forms of exercise for people to do, which targets both the Cardio and Respiratory system, and makes the short term effects worth it in the long run. The huge differences in the short and long term effects are that instead of the body become fatigue and worn out, and the lungs having to work hard so that the body can breath properly with out becoming dangerous, the body has now adapted to the pace needed with a higher maximum oxygen uptake and the increases of the heart, so that it don't struggle to pump blood to the muscles. The best improvement is that the resting heart rate is decreased. The result of both running and swimming in the short and long term on the Cardiovascular and Respiratory System show that both forms of exercise are healthy and a great way to build up the strength and stamina of both of them, it takes time and effort for the body (Cardio and Resp) to develop and change and it isn't a overnight thing. Going running or swimming once won't make a difference on the body unless it is performed regularly and correctly. ...read more.

    Blood is diverted from other organs, such as the gut, by local vasoconstriction. Myocardial contractility may increase. Venoconstriction results in an increased venous return, and splenic contraction increases the packed cell volume and oxygen carrying capacity of blood.
