Maintenance of pH and temperature


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.
