What to Focus On
- Excretion means removal of wastes from the body.
- Major wastes include ammonia, urea, uric acid, bile pigments, excess salts, water, and carbon dioxide.
- Ammonia is the most poisonous waste product.
- Human excretory system has kidneys, ureters, urinary bladder, and urethra.
- Kidneys are bean-shaped and reddish brown.
- Right kidney is lower than left kidney because of the liver.
- Outer kidney region is cortex; inner region is medulla.
- Nephron is the structural and functional unit of the kidney.
- A nephron has Malpighian body and renal tubule.
Common Mistakes to Avoid
The right kidney is higher than the left kidney because the body is not perfectly symmetric.
The efferent arteriole is wider than the afferent arteriole because it carries blood away from the glomerulus.
Bowman's capsule and glomerulus are separate structures with no special name together.
