briefly explain how oxygen transported from
Answers
Answer:
OXYGEN TRANSPORT IN BLOOD CAPILLARIES. In the capillaries, oxygen is transported within red cells through the solution of hemoglobin, then through the cell membrane and the blood plasma. Since cells and plasma are in motion, both convection and diffusion (free and facilitated) may be important.26-Ma
Answer:
Oxygen is essential for ATP generation through oxidative phosphorylation, and therefore must be reliably delivered to all metabolically active cells in the body.[1][2] In the setting of hypoxia or low blood oxygen levels, irreversible tissue damage can rapidly occur. Hypoxia can result from an impaired oxygen-carrying capacity of the blood (e.g., anemia), impaired unloading of oxygen from hemoglobin in target tissues (e.g., carbon monoxide toxicity), or from a restriction of blood supply. Blood becomes typically saturated with oxygen after passing through the lungs, which have a vast surface area and a thin epithelial layer that allows for the rapid diffusion of gasses between blood and the environment.
