Explanation

Learning Outcomes

The kidneys are the primary organs for filtration of blood in the body. The kidneys are also responsible for removing and excreting the waste products in the blood. The kidneys are responsible for hemostasis of the extracellular fluids, osmolarity regulation, ph regulation, and the kidneys produce erythropoietin to stimulate red blood cells and renin which controls salt and water balance plus blood pressure control. The three phases of urine formation include filtration, reabsorption, and secretion. These three processes make sure that only excess water and waste are eliminated from the body.

Test Taking Tip

It is important to know the functions of the vital organs to include the kidneys, heart, lungs, and liver.
