Excretion (The star terms) Not on Term 2 summative Flashcards
Antidiuretic Hormone (ADH)
A hormone produced by the pituitary gland that increases the reabsorption of water in the kidney tubules
Bladder
The organ that collects and holds urine
Bowman’s capsule
The cup-like structure at the start of the nephron before the ureter from where the filtrate from the glomerulus is collected and taken to the tubules
Collecting Dust
The final part of the nephron before the ureter in which water is selectivley absorbed. Its permeability to water is altered by ADH
Convoluted Tubules
Tubes of the nephron through which filtrate flows. Substances from the filtrate are reabsorbed into the blood in the convoluted tubes.
Glomerulus
A collection of capillaries that is involved in the filtration of blood under high pressure.
Loop Of Henle
Part of the nephron in which water and salts are reabsorbed
Nephron
The functional unit of the kidney
Osmoregulation
The regulation of the volume of water in body fluids
Selective Reabsorption
The selective reuptake of useful substances (all sugars, some water and some ions) into the blood. This takes place along the nephron
Ultrafiltration
The filtration of blood at the glomerulus to produce a filtrate which contains water, ions, glucose, urea and other molecules. Proteins and cells are not present in the filtrate
Ureters
The tubes that carry urine from the kidneys to the bladder
Urethra
The tube that carries urine from the body to outside the body during urination
Urine
The waste product of the kidney that contains water, urea and ions
