IMMUNOLOGY

Detailed explanation-1: -Homeostasis is the regulation of the internal conditions within cells and whole organisms such as temperature, water, and sugar levels. This keeps cells and organisms functioning at optimal levels even when challenged by internal and external changes.

Detailed explanation-2: -To achieve “body fluid homeostasis” or “Na homeostasis”, the brain continuously monitors [Na+] in body fluids and controls water/salt intake and water/salt excretion by the kidneys.

Detailed explanation-3: -Osmoregulation. Osmoregulation is the active regulation of the osmotic pressure of bodily fluids to maintain the homeostasis of the body’s water content; that is it keeps the body’s fluids from becoming too dilute or too concentrated.

Detailed explanation-4: -The part of the cell that helps maintain homeostasis is the plasma membrane. The plasma membrane is the flexible barrier that surrounds the outside of the cell. The plasma membrane regulates what enters and leaves the cell and allows the cell to keep their internal conditions separate from the environment.
