Study Notes
Nephron Components
- Glomerular Capsule: Encloses the glomerulus; initiates filtration of blood to form urine.
- Efferent Arteriole: Transports filtered blood away from the glomerulus; maintains glomerular filtration pressure by regulating blood flow.
- Glomerulus: A network of capillaries where blood filtration occurs; crucial for the formation of urine.
- Proximal Tubule: First segment of the renal tubule; responsible for reabsorbing nutrients, electrolytes, and water from the filtrate back into the blood.
- Afferent Arteriole: Supplies blood to the glomerulus; its diameter influences glomerular filtration rate.
- Loop of Henle: A U-shaped tube that concentrates urine; plays a key role in water reabsorption and electrolyte balance.
- Collecting Duct: Collects urine from multiple nephrons; regulates water and sodium reabsorption controlled by hormones.
- Distal Tubule: Site for further ion and water reabsorption; contributes to the regulation of blood pH and electrolyte levels.
- Renal Cortex: The outer layer of the kidney; contains nephron structures and is involved in blood filtration and processing.
- Renal Medulla: The inner region of the kidney; contains the Loop of Henle and collecting ducts; vital for urine concentration.
