Study Notes
Location and Structure of Adrenal Glands and Kidneys
- Adrenal glands are located superior to each kidney
- Each kidney is protected by three concentric layers of connective tissue: renal capsule, adipose capsule, and renal fascia
Functions of the Urinary System
- Excretion: removal of organic wastes from body fluids
- Elimination: discharge of waste products, including nitrogenous wastes, toxins, and drugs
- Homeostatic regulation: maintenance of water balance, electrolytes, acid-base balance in the blood, blood pressure, and red blood cell production, as well as activation of vitamin D
Gross Anatomy of the Urinary System
Kidneys
- Organs that excrete urine
Urinary Tract
- Organs that eliminate urine:
- Ureters (paired tubes)
- Urinary bladder (muscular sac)
- Urethra (exit tube)
Other Organs and Structures
- Hepatic veins
- Inferior vena cava
- Adrenal glands
- Renal artery
- Renal hilus
- Renal vein
- Aorta
- Iliac crest
- Rectum
- Uterus (part of female reproductive system)
- Urinary bladder
- Urethra
Learn about the location and structure of the kidneys, including the adrenal glands and the protective layers of connective tissue. Test your knowledge of the renal capsule, adipose capsule, and renal fascia.
