AND ANSWERS A*/ 2026-

What is the overall goal of the kidney? - answer- To maintain homeostasis. What are the two main regions of the kidney? - answer- Renal Cortex and Renal Medulla. What comprises the Renal Corpuscle? - answer- The Glomerulus and Bowman's Capsule. What are the three basic renal processes? - answer- Glomerular Filtration, Tubular Secretion, and Tubular Reabsorption. What is Glomerular Filtration? - answer- The movement of blood to tubule. What is Tubular Secretion? - answer- The movement of substances from peritubular capillaries into tubular lumen. What is Tubular Reabsorption? - answer- The movement from tubule to blood. What does GFR stand for? - answer- Glomerular Filtration Rate. What is the normal GFR value? - answer- 125 ml/min. What does the term 'Transport Maximum (Tmax)' refer to? - answer- The maximum amount of material that can be transported per unit time when binding sites on transport proteins are saturated.

What is the primary mechanism of Tubular Reabsorption? - answer- Diffusion and Mediated Transport. What is an example of Primary Active Transport in the kidney? - answer- Na+ via Na+/K+- ATPase. What is an example of Secondary Active Transport in the kidney? - answer- Glucose via Glucose/Na+ Co-transport. What is the function of the Proximal Tubule? - answer- Reabsorbs most of filtered water and non- waste solutes. What is the role of the Loop of Henle? - answer- Establishes the medullary osmotic gradient. What occurs in the Distal Segments of the nephron? - answer- Fine-tuning of homeostatic controls for most substances. What is the significance of measuring GFR? - answer- It indicates glomerular function and kidney health. What is the formula for calculating GFR? - answer- GFR = V • Us / Ps. What is the filtered load? - answer- The amount of a substance filtered at the glomerulus. What substance is commonly used to measure GFR? - answer- Inulin or Creatinine. How does Tubular Secretion function? - answer- It excretes substances at a rate greater than filtered at the glomerular capillaries.
