Study Notes
Evaluating Renal Function
- The primary method of evaluating renal function is by measuring the glomerular filtration rate (GFR).
Hormones and Kidney Function
- Antidiuretic hormone (ADH) acts on the cells of the collecting ducts in the kidneys to increase water reabsorption.
Osmolality
- The physical property of a solution based on the concentration of solutes per kilogram of solvent is osmolality.
Plasma Osmolality
- When individuals consume more fluids in response to increased blood osmolality, the osmolality of plasma decreases.
Glomerulus Function
- The main function of the glomerulus in the nephron is to filter the blood and produce a filtrate.
Tubular Reabsorption
- The following substances are returned to the body during tubular reabsorption: glucose, amino acids, and electrolytes.
Hormones and Ion Regulation
- Parathyroid hormone (PTH) promotes tubular reabsorption of calcium and phosphate excretion in the kidneys.
- Aldosterone promotes sodium reabsorption in the nephron.
Erythropoietin Function
- The primary function of erythropoietin produced by the kidneys is to stimulate the production of red blood cells.
Renin's Role
- Renin, an enzyme produced by the kidneys, helps to regulate blood pressure by stimulating the renin-angiotensin-aldosterone system.

Description
Learn about the functional unit of the kidney, the nephron, and the various important functions of the kidneys such as regulating water, electrolyte, and acid-base balance. Explore how the kidneys excrete waste products like urea, creatinine, and uric acid, and understand the endocrine roles of the kidneys in hormone production. Dive into topics like arginine vasopressin, aldosterone, and parathyroid hormone.
