Urinary Elimination
Physiology | Urinary Elimination |
---|---|
Upper urinary tract | Kidneys and ureters |
Lower urinary tract | Bladder, urethra, and pelvic floor |
Functional units of the kidney | Nephrons |
Tuft of capillaries surrounde by Bowman's capsule | Glomerulus |
Made up of water, electrolytes, glucose, amino acids, and metabolic wastes | Glomerular filtrate |
Location in the nephron where most of water is absorbed | Proximal convoluted tubule |
Location in the nephron where glucose is reabsorbed | Loop of Henle |
This substance is released from the adrenal cortex causing sodium and water reabsorption to increase blood volume. | Aldosterone |
Moves urine from the kidneys to the bladder | Ureters |
Hollow, muscular organ that serves as a resevoir for urine | Bladder |
This muscle allows the bladder to expand as it fills with urine, and to contract to release urine to the outside of the body during voiding. | Detrusor muscle |
This connects the bladder to the urinary meatus | Urethra |
The length of a male's urethra | Eight inches |
The process of emptying the urinary bladder | Micturation |
