Questions and Answers

Name the five toxic nitrogenous wastes and their effects on the body.

The five toxic nitrogenous wastes are ammonia, urea, uric acid, creatine, and creatinine. They can cause diarrhea, vomiting, cardiac arrhythmia, convulsions, coma, and death.

What are the functions of the kidneys?

The functions of the kidneys include filtering blood plasma, separating wastes, returning useful materials to the blood, eliminating wastes, regulating blood volume and osmolarity, producing hormones (renin, erythropoietin, calcitriol), regulating acid-base balance of body fluids, and detoxifying superoxides, free radicals, and drugs.

Study Notes

Kidney Functions and Structure

  • The kidneys produce three hormones: erythropoietin, calcitriol, and renin.
  • The kidneys are located in the lower back, one on each side of the spine, protected by the rib cage.

Toxic Nitrogenous Wastes

  • The five toxic nitrogenous wastes are: urea, uric acid, creatinine, ammonia, and amino acids.
  • These wastes can cause harm to the body, such as:
    • Urea: can cause kidney failure and damage to other organs
    • Uric acid: can cause gout and kidney stones
    • Creatinine: can cause kidney damage and muscle cramps
    • Ammonia: can cause brain damage and death
    • Amino acids: can cause metabolic disorders and acid-base imbalance

Kidney Structure

  • The medial surface of the kidney is concave, with a groove called the hilum.
  • The hilum is located at the medial border of the kidney and is where the renal artery, renal vein, and ureter enter the kidney.

Urinary System

  • The primary function of the urinary system is to remove waste and excess fluids from the body.

What the Kidneys Do Not Do

  • The kidneys do not produce insulin, which is produced by the pancreas.
