Question

What are two homeostatic functions of the blood?

Answer 1

Maintenance of pH and temperature

Explanation:

pH homeostasis
Blood plays an important role in keeping the pH (acidity / basicity) within a very narrow acceptable range: around pH `7.4`. This is essential for good functioning of all organs.

Temperature homeostasis
Blood also has an important role in keeping the body temperature within an acceptable range: around `37 ^oC`. Blood can carry heat from and to tissues. Restriction and dilation of vessels support this process.
