Detailed explanation-1: -The urinary system maintains blood homeostasis by filtering out excess fluid and other substances from the bloodstream and secreting waste.
Detailed explanation-2: -The kidneys help regulate blood pressure through Na+ and water retention and loss. The kidneys work with the adrenal cortex, lungs, and liver in the renin–angiotensin–aldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water.
Detailed explanation-3: -Homeostasis is the body’s attempt to maintain a constant internal environment. One of the major ways the body achieves homeostasis is through excretion, the process of removing wastes and excess water from the body.
