Answers
The chemical reactions of life take place in aqueous solutions. The dissolved substances in a solution are called solutes. In the human body, solutes vary in different parts of the body, but may include proteins—including those that transport lipids, carbohydrates, and, very importantly, electrolytes. Often in medicine, a mineral dissociated from a salt that carries an electrical charge (an ion) is called and electrolyte. For instance, sodium ions (Na+) and chloride ions (Cl–) are often referred to as electrolytes.
In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane. As a result, water will move into and out of cells and tissues, depending on the relative concentrations of the water and solutes found there. An appropriate balance of solutes inside and outside of cells must be maintained to ensure normal function.
Answer:
Most homeothermic creatures include osmoreceptors, which are sensory receptors that typically reside in the hypothalamus and are capable of detecting changes in osmotic pressure.
Explanation:
- They are mainly located in the kidneys and hypothalamus.
- Blood and fluid osmolarity must be carefully monitored since fluctuations may cause water to enter or exit cells, impairing cell function and, in severe cases of high osmolarity, causing cells to explode.
- Water moves into the cell along the osmotic gradient when the blood's osmotic pressure increases, causing the cell to inflate.
- When the osmotic pressure is low, the opposite occurs.
- This causes neuronal signals to be delivered to the hypothalamus instructing it to release more ADH to raise blood osmotic pressure or less ADH to lower blood osmotic pressure.
The concentration of body fluids is altered by osmoreceptors.
