Regulation:
1-Blood vessels help maintain a stable body temperature by controlling the blood flow to the surface of the skin.
2-In the case of hypothermia, these blood vessels constrict to keep blood flowing only to vital organs in the body’s core.
3-Blood also helps balance the body’s pH due to the presence of bicarbonate ions, which act as a buffer solution.
4-Finally, the albumins in blood plasma help to balance the osmotic concentration of the body’s cells by maintaining an isotonic environment
