Describe what happens when blood in capillaries flows past cells.
Answer (2)
If the blood is carrying oxygen, the cell and the blood will have a sort of trade. The cells will give the blood the waste which will leave the body and the blood will give the cell oxygen which it needs to stay alive and continue to work.
When blood flows through capillaries, oxygen and nutrients diffuse from the blood into surrounding cells, while waste products like carbon dioxide move from the cells into the blood. This exchange is facilitated by the thin walls of the capillaries, allowing for efficient material transfer. The process is crucial for maintaining cellular health and homeostasis.
