D1: Unit 5: Use examples to explain how body systems interrelate with each other How body systems interrelate with each other? The role of the digestive system producing energy is the big part of our energy, this is because it comes from food (we eat) and oxygen (we breathe in) but there are processes for this food. The journey for the food from eating till being energy is beginning in the digestive system. Food and drink must be digested and changed into smaller molecules of nutrients so that the digestive system does its job by breaking into smaller molecules. This start in the mouth where is the food is broken by chewing into small parts and be slippery bolus so it slipper easily through the throat, then to the stomach which produce enzymes and stomach acid to break these food into very small molecules. The role of the cardio- vascular system: The small molecules of food now can be absorbed into the blood by the cells and it goes up to the heart where it pumps to the lung to get oxygenated. ...read more.


The food is broken down in the cells and helps functions your body. Respiration brings oxygen into the body, and releases carbon dioxide. When you inhale, you take in oxygen, which in turn is carried through the blood to different muscles and organs to make them work. All body systems are related with each other and the best example is the relation of the nervous system with the other systems. In fact, nervous system is responsible for the controlling the voluntary and involuntary actions of the other systems. Similarly, the respiratory and circulatory systems are related. When a person breathes, they inhale oxygen which is distributed to each cell of the body through the circulatory system. Digestion is related with excretory system because when we eat or drink anything, in the digestive system the important nutrients are protected in the body and wastes are excreted out. In this way all of the systems are linked with each other. ...read more.


The endocrine system regulates mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes. The central nervous system consists of the brain and spinal cord, which serve as the main processing center for the entire nervous system, receiving and interpreting sensory information via electrical signals. The digestive system (also known as the alimentary canal) is the system of organs that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. The respiratory system is made up of the lungs, airways, diaphragm, windpipe, throat, mouth, nasal passages, pharynx and larynx. This respiration process moves oxygenated air throughout the system into the blood stream. The integumentary system and its components, skin, hair, nails, skin glands and their products (sweat and slime)--is the body's largest organ system. This system consists of two layers: the epidermis and the subdermis. These nine systems provide the body with sustenance, heat, air and protection it needs. Each system depends on the other systems' input to provide good health and peak performance. http://www.ehow.com/how-does_5171733_do-body-systems-interrelate_.html ?? ?? ?? ??

    Salivary, gastric, pancreatic, biliary and intestinal secretions are produced to give mucus for protection. The digestive system uses muscle contractions to help break up the food. The smooth muscle that is located inside the stomach turns the food that is ingested into liquid which is then passed inside the small intestine.
