To review:
Whether the following statements are true or false. False statements are to be corrected.
a. The thirst mechanism is mediated by osmoreceptors located in the cerebral cortex.
b. The sensible water loss includes the water lost from the body via the skin and the respiratory system.
c. The main hormone that regulates fluid balance is antidiuretic hormone (ADH).
d. Atrial natriuretic peptide promotes water retention in the kidneys and increases the amount of water in the body.
e. Dehydration is characterized by a decreased volume and increasedosmolarity of the ECF.
Introduction:
The body fluids, electrolytes, acids, and bases play an important role in the human’s organ system. The amount of water in the ECF and in the human body is maintained by the organ’s function. Anyimbalance can cause a change in the osmolarity of the ECF.
