Key definitions of filtration, absorption, and secretion. … WebPeritubular capillaries are tiny blood vessels in your kidneys. They filter waste from your blood so the waste can leave your body through urine (pee). Peritubular capillaries also reabsorb nutrients your body needs to work properly, such as minerals. You have millions of these capillaries inside your kidneys’ nephrons (filtering units).
WebFormation of urine. Topic: Excretory System. The formation of urine takes place in the nephron, which is the structural and fundamental unit of the kidney. It occurs through three steps: glomerular filtration, tubular reabsorption, and tubular secretion. The first step of the formation of the urine is glomerular filtration in the glomerules. WebIn kidney, excretion of drugs depends on glomerular filtration, active tubular secretion, and passive tubular absorption. Urine and blood pH and the physical characteristics of the drug molecule are important in determining whether the …
WebUrine pH, which varies from 4.5 to 8.0, may markedly affect drug reabsorption and excretion because urine pH determines the ionization state of a weak acid or base (see Passive diffusion Passive diffusion Drug absorption is determined by the drug’s physicochemical properties, formulation, and route of administration.
