The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing. Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body. The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required or when living at higher altitudes.
Gills are rich in blood vessels that bring blood close to the surface for gas exchange, the respiratory function. The circulatory system then carries the oxygen from the gills to the cells of the body, providing the cells with the necessary oxygen to carry out cellular respiration.ills are rich in blood vessels that bring blood close to the surface for gas exchange, the respiratory function.
