They're all necessary to live. And each system depends on the other system to help you survive. 13 Lessons in Chapter Human Digestion, Respiration, Circulation & Excretion Systems. Chapter Practice Test. Test your knowledge with a question. Relationship Between Respiration & Metabolism. By Roxann Respiration Occurs in the Lungs Why Do We Need Enzymes for Digestion?.
Sciencing Video Vault What is Metabolism? All the chemical reactions that occur in the body are metabolic reactions. Some reactions break down molecules to make energy while other reactions build up molecules and use energy. Reactions that use energy include making new membrane, making proteins that determine the shape of the cell, and making molecules that are secreted from the cell.
Every cell also has to store energy from nutrients so there is enough energy to make needed molecules. ATP is broken down to adenosine diphosphate ADP and the released energy is used to make other molecules. Food Provides Raw Materials Food is digested into small molecules that can enter the blood stream. Sugars and fiber are broken down to small sugar molecules.
Protein is broken down to amino acids. The results of respiratory activity allow the digestive tract to function, and vice versa. Furthermore, the systems work together to provide energy to body cells.

Digestive Function The purpose of your digestive system is to take in food from your environment and break it down on both macroscopic and molecular levels. Through the process of digestion, you break large nutrient molecules into smaller ones that your intestine absorbs into the bloodstream. Cells then take up these nutrient molecules and use them to build new molecules and provide for their cellular energy needs.
Cells can also store the molecules for later use. Respiratory Function Your respiratory system takes in oxygen from the atmosphere and moves that oxygen into the bloodstream by allowing it to move across the membranes of the lungs into the blood vessels.
The muscular system helps push air come into and leave the respiratory system through the contraction and relaxation of the diaphragm, which is a muscle. The respiratory system has the lungs that deliver air to the muscles. It is kind of weird to think of or read about how your muscles works, and then knowing what they are doing right at that second.

This system actually makes you feel what you feel. Plus, it helps the respiratory system by allowing you feel and know when you are breathing and have somewhat control of it. The nervous system also triggers you to whine or scream when you get physically hurt.
These systems are amazing. I have learned a lot from writing this essay.Oxygen’s surprisingly complex journey through your body - Enda Butler
I learned how the digestive system breaks down food. How the skeletal system protects the lungs.
