Excretion Flashcards
(37 cards)
Afferent arteriole
The blood vessel that enters an organ
Collecting duct
The tube in the kidney that collects filtrate from several nephrons
Creatinine
A waste product from the breakdown of muscles.
Deamination
The removal of the amino group from an amino acid molecule
Dialysis
A method of removing waste from the blood when kidney failure occurs
Distal convoluted tubule
The second set of convolutions of the kidney tubule;
It receives the forming urine after it has passed through the loop of Henle
Efferent arteriole
The blood vessel that leaves a glomerulus in the kidney
Excretion
Removal of the wastes of metabolism from the body.
Facultative reabsorption
The process whereby carrier proteins assist the movement of substances through the cell membrane
Filtrate
The fluid remaining after filtration has taken place
Glomerular capsule
The double-walled cup like structure at the end of each kidney tubule. It collects filtered water and other substances from the blood.
Bowman’s capsule.
Glomerular filtration
The filtration of blood in the kidney.
Glomerulus
The tightly coiled mass of capillaries that is surrounded by the expanded part of each kidney tubule.
Kidney stone
Solid mass of crystals that develop within the kidneys
Kidneys
The principal excretory organs of the human body;
they filter wastes from the blood and regulate the balance of water and salts in the blood plasma.
Liver
Organ that is part of the excretory system. Helps process toxins.
Loop of Henie
The U shaped section of the kidney tubule; it plays a major role in the reabsorption of water and salts from the filtrate
Nephron
The functional unit of the kidney.
Peritubular capillaries
The capillaries in the kidney that surround the convoluted tubules of the nephron, the loop of Henle and the collecting duct.
Proximal convoluted tubule
The first set of convolutions of the kidney tubule, located between the glomerular capsule and the loop of Henle
Renal artery
The blood vessel that transports blood into the kidney.
Renal capsule
A tough fibrous layer surrounding the kidney.
Renal column
An extension of the renal cortex that divides the renal medulla into renal p.yramids
Renal cortex
The outer part of the kidney
