The vacuole
the kidneys
There are far more than three conditions that are controlled inside your body. Examples are temperature, oxygen level, blood sugar level, pH of our blood, blood electrolyte levels, heart rate, and muscle tone. The maintenance of a relatively stable body state is known as homeostasis.
The kidney is the organ that manages the water content of the blood. People typically have two.
it regulates the water content of the cell, eliminating excess water, thereby maintaining osmotic potential
The hormone that regulates blood composition and blood volume by acting on the kidney is aldosterone. It is produced by the adrenal glands and helps to control the balance of water and electrolytes in the body by promoting the reabsorption of sodium and water in the kidneys.
the body regulates sodium level by adding water to blood in circulation, that contibutes to increasing blood pressure.
The most important hormone that regulates blood osmolality is antidiuretic hormone (ADH), also known as vasopressin. ADH acts on the kidneys to regulate water reabsorption, helping to maintain proper balance of water and electrolytes in the blood.
Urinary system
Albumin gives your blood 'weight'. It maintains the oncotic pressure of blood and prevents water leaving the blood abnormally by osmosis and draining into the cells.
The hypothalamus
The kidneys play a key role in maintaining pH balance in the blood by regulating levels of acids and bases. They also help regulate water content in the blood through processes like reabsorption and excretion, ensuring that the body maintains proper hydration levels.
