Study Notes
Kidneys
- Main function is to remove nitrogenous wastes (e.g., urea), salts, and excess water from the blood, producing urine.
- Millions of nephrons, the functional units of kidneys, facilitate this filtration process.
Ureter
- Muscular ducts responsible for transporting urine from the kidneys to the urinary bladder.
- Utilizes peristalsis to propel urine through a series of contractions.
Urinary Bladder
- Collects and stores urine excreted by the kidneys before elimination.
- Has the capacity to expand and contract to hold varying amounts of urine.
Urethra
- Connects the urinary bladder to the external environment, allowing for urine excretion.
- Functions in both males and females for waste elimination, varying in length between genders.
Renal Artery
- Supplies kidneys with a significant portion of blood flow, essential for filtration and waste removal.
- Branches from the aorta, ensuring a rich supply of oxygenated blood to the kidneys.
Renal Veins
- Drain purified blood from the kidneys, connecting them to the inferior vena cava.
- Play a crucial role in returning cleansed blood back to the systemic circulation.
Aorta
- Largest artery in the body, responsible for distributing oxygen-rich blood to all body parts.
- Functions as the primary vessel for systemic circulation, conducting blood from the heart.
Inferior Vena Cava
- Major vein that conveys deoxygenated blood from the lower body back to the heart.
- Empties into the right atrium, playing an essential role in systemic venous return.
