Study Notes
Urinary System Anatomy
- The urinary system consists of organs that filter blood and produce urine.
- Key organs include kidneys, ureters, bladder, and urethra.
Kidney Function
- Kidneys filter blood, removing waste products and excess water.
- They regulate blood pressure, electrolyte balance, and red blood cell production.
Urinary Tract Infections (UTIs)
- UTIs are infections of the urinary tract.
- Common causes include bacteria.
- Symptoms may include pain, burning during urination, and frequent urination.
Fluid Balance Regulation
- Kidneys play a vital role in maintaining fluid balance in the body.
- They regulate the amount of water and electrolytes in the blood, which is crucial for homeostasis.
Nephron Structure and Function
- The nephron is the functional unit of the kidney.
- It filters blood, reabsorbs necessary substances, and secretes waste products into the urine.
- Parts of the nephron include the glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.
Kidney Structure
- The kidney has an outer cortex and an inner medulla.
- The medulla contains loops of Henle, which assist in concentrating urine.
Blood Filtration to Urine Formation
- Blood enters the kidney through the renal artery.
- In the nephron, the glomerulus filters blood, and the remaining fluid enters Bowman's capsule.
- The filtrate travels through the convoluted tubules, where substances are reabsorbed or secreted.
- Waste products form urine and are collected in the collecting ducts, eventually flowing into the ureters.
Micturition Reflex
- The micturition reflex controls the emptying of the bladder.
- This is a complex neurological process that involves the brain and nerves, leading to the contraction of bladder muscles and relaxation of the sphincter muscles.
ADH and Aldosterone Function
- Antidiuretic hormone (ADH) regulates water reabsorption in the kidneys, affecting urine volume.
- Aldosterone regulates sodium and potassium levels in the blood, influencing blood pressure.
