Study Notes
Excretory System Regulation
- The excretory system is regulated by the kidneys, which filter waste and excess substances from the blood
- The kidneys regulate electrolyte balance, acid-base balance, and blood pressure
- The kidneys also produce hormones that help regulate red blood cell production, blood pressure, and calcium levels
Ureter Anatomy
- The ureters are muscular tubes that connect the kidneys to the bladder
- Each ureter is about 25-30 cm long and 3-4 mm in diameter
- The ureters have a spiral muscle layer that helps propel urine towards the bladder
- The ureters enter the bladder at an angle, preventing urine from flowing back up into the kidneys
Kidney Function
- The kidneys filter approximately 1.5 liters of blood per minute
- The kidneys remove waste and excess substances from the blood, regulating electrolyte and acid-base balance
- The kidneys also produce hormones that help regulate red blood cell production, blood pressure, and calcium levels
- The kidneys have a built-in autoregulatory mechanism to maintain a stable blood pressure
Urine Formation
- Urine formation occurs through the process of filtration, reabsorption, and secretion
- The glomerulus filters the blood, producing a filtrate that enters the renal tubules
- The renal tubules reabsorb water and electrolytes, and secrete waste products
- The collecting ducts concentrate or dilute the urine depending on the body's needs
Bladder Physiology
- The bladder is a muscular sac that stores urine
- The bladder has a layer of transitional epithelium that allows it to stretch and expand
- The bladder has a trigone area that helps prevent reflux of urine into the ureters
- The bladder's detrusor muscle contracts to expel urine during micturition
