How wiil you describe the pathway of oxygen in the breathing system?
In air breathing animals, the lings are the organ system that takes in air and extracts oxygen for distribution through the circulatory system. In water breathing animals, the gills perform this function. Those smaller animals that have neither lungs nor gills usually have a system for direct absorption of oxygen from the air, or water.
The respiratory system co-operates with the circulatory system. The functions of the respiratory system is to gather oxygen by breathing via the nose or mouth. The oxygen then travels to the lungs where the capillaries in the lungs fill with fresh oxygen where it can then be distributed throughout the body.
The function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.
How does iron deficiency anaemia affect the circulatory system digestive system and respiratory system?
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's way of getting oxygen to the blood.
Breathing is the movement of air into and out of the lungs. Respiration is the exchange of oxygen and carbon dioxide. Oxygen is picked by and carried to the cardiovascular system and taken to the cells. The cells take up the oxygen and release the carbon dioxide back into the CVS and out to the lungs. The lungs take in oxygen and release carbon dioxide.
The autonomic nervous system is the system of nerves and brain functions that operates without conscious control, such as breathing, sweating, salivating, etc. When your body needs more oxygen, for example, the autonomic nervous system sends signals from your brain to the lungs to breathe more deeply. Although you can consciously control your breathing to an extent, the autonomic nervous system takes over if you deprive yourself of too much oxygen. That's why we keep…
