Study Notes
Urinary System Overview
- Composed of kidneys, ureters, urinary bladder, and urethra
- Kidneys: filter blood and produce urine
- Filtration rate: 90-120ml/minute
- Functions include waste removal, fluid balance, and electrolyte regulation
- Kidneys also produce hormones (e.g., renin for blood pressure, erythropoietin for red blood cell production) that impact bone health
Urinary System Structure
- Kidneys lie between the 12th rib and 3rd lumbar vertebra, slightly lower on the left side.
- Renal sinus: the cavity within each kidney where urine collects
- Renal cortex: the outer layer
- Renal medulla: the inner layer
- Renal pelvis: collecting area for urine that leads to the ureters
Nephron Structure
- Functional unit of the kidney
- Consists of renal corpuscle (glomerulus and Bowman's capsule) and renal tubule
- Renal corpuscle filters the blood
- Renal tubule reabsorbs essential substances & secretes waste
- Includes proximal convoluted tubule, loop of Henle, distal convoluted tubule and collecting duct
Urinary System-Ureters
- Tubes that carry urine from the kidneys to the bladder
- Peristaltic movement aids urine transport
Urinary System-Urinary Bladder
- Stores urine until it's excreted
- Has a significant capacity 500-800ml
Urinary System-Urethra
- Tube that carries urine out of the body
- Structure differs between genders
Reproductive System Overview
- Has primary sex organs and accessory structures
- Primary: the gonads (testes in males and ovaries in females)
- Accessory: include the ducts and glands, as well as the external genitalia
Reproductive System-Male Reproductive System
- Testes: produce sperm and testosterone
- Ducts: carry sperm from the testes to the outside
- Accessory glands: provide fluids to nourish sperm
Reproductive System-Female Reproductive System
- Ovaries: produce eggs and estrogen
- Ducts: transport the egg from the ovary to the uterus
- Accessory structures: uterus, fallopian tubes, vagina.
