Question

What controls the water balance between body cells and their environment?

Answer 1

Answer:

Kidney

Explanation:

Humans are multicellular in conflict with the External Environment (external environment) and the cells also live in an environment that contains blood and other bodily fluids. Fluid 60% of the total body weight of adult men. In body fluids dissolved food substances and ions needed by cells to live, develop, and carry out their functions. To be able to activate its function properly is in accordance with the surrounding environment. All regulate physiologically to maintain a normal state called homeostasis. This homeostasis depends on the body's ability to maintain a balance between substances in the interior.

The regulation of fluid balance needs to be considered 2 (two) important parameters, namely: extracellular fluid volume and extracellular fluid osmolarity. The kidneys control fluid volume by maintaining salt balance and controlling fluid volume by maintaining fluid balance. The kidneys maintain balance by renewing water and salt as needed to compensate for the intake and abnormal decrease of the water and salt.

Good Morning!
 
The entry and exit of substances from cells occurs through the plasma membrane. The control of external and internal water balance is performed through the osmosis process. In osmosis, water moves according to solute concentrations: always from the lowest concentration to the highest concentration.
