All body systems are related with each other. 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, respiratory and circulatory system are related. When a person breaths, he inhales 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.
The role of the digestive system producing energy The big part of our energy is come from food and oxygen 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 and that the digestive system does this job it broke this food into smaller molecules. This start in the mouth where is the food broken to 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 go up to the heart where it pumps to the lung to get oxygenated. Then after it come back from the lung the heart pumps it gain to the whole body and give the nutrient to all body, so during the blood circulation the body get oxygenated and deliver the oxygen and the nutrients require to produce the energy then by the muscles cells this where the mixed of the oxygen and the substance from food (glucose ,amino acid or fatty acids ) produces the energy which would be in appearance of nucleic acid Adenosine Triphosphate which it stores energy and when the body needs energy then muscles vessels turn ATP to physical energy Respiratory system In the lung the blood get oxygenated (lung provide oxygen) by the oxygen in the lung then it go back to the heart.
Body systems are set to do particular task in the body. All the body parts interact together for a purpose. No single part of the organ can do the job alone, and any delay or illness is likely to affect the body system. The respiratory system provides a way of exchanging nutrients and waste between our bloods. Its main function is to provide the blood with oxygen from the surrounding atmosphere, and to release the waste product carbon dioxide back into the atmosphere. The digestive system takes the food that you eat, and turns it into energy. The food is broken down in the cells and helps function 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.
