Chapter 10: Filtration and Reabsorption in Renal Physiology

These flashcards cover key vocabulary and concepts related to renal filtration and reabsorption processes.

Colloid Pressure

The pressure caused by colloidal particles in a fluid, influencing the filtration rate.

Glomerular Capsule Pressure

The hydrostatic pressure within the glomerular capsule that affects filtration rates.

Tubular Reabsorption

The process by which substances are reabsorbed from the renal tubule back into the blood.

Facilitated Diffusion

A process of passive transport that allows substances to cross membranes with the help of specialized proteins.

Osmosis

The movement of water through a semi-permeable membrane from areas of low solute concentration to areas of high solute concentration.

Peritubular Capillaries

Capillaries surrounding the renal tubules, involved in reabsorption and higher permeability.

Proximal Convoluted Tubule

The segment of the renal tubule where most reabsorption occurs, characterized by microvilli.

Active Transport

The energy-requiring process that moves substances against their concentration gradient, often using ATP.
