Urinary System Flashcards
Excretion
Removal of metabolic wastes from the body
The urinary system produces ______
Urine
The kidneys excrete metabolic waste, mostly _____
Nitrogenous wastes
The breakdown of amino acids in the liver release _______, which the liver rapidly combines with carbon dioxide to produce _____
Ammonia Urea
Glomerular filtration
Water, salts, nutrient molecules, and waste molecules move from the glomerulus to the inside of the glomerular capsule
Tubular reabsorption
Nutrient and salt molecules are actively reabosrbed from the convoluted tubules into the peritubular capillary network, and water flows passively
Tubular secretion
Certain molecules are actively secreted from the peritubular capillary network into the convoluted tubules
Ureters
Conduct urine from the kidneys to the bladder
Osmoregation
Regulation of the water-salt balance to maintain a normal balance within internal fluids
Glomerulus
A knot of capillaries inside the glomerular capsule
Afferent
Going towards
Efferent
Going away
Efferent arteriole
Takes blood to the peritubular capillary network
Glomerular capsule is also known as
Bowman’s capsule
The glomerular capsule connects to the
proximal convoluted tubules (PCT)
The loops of Henley connects to the
Distal convoluted tubule (DCT)
The DCT have
Mitochondria but no microvilli
DCT isn’t specialized for reabsorption
What lies In the renal cortex
Glomerular capsule and PCT AND DCT
What lies in the renal medulla
The look of henle and collecting duct
What does the efferent arteriole do?
Small molecules that escape being filtered and the nonfilterable components leave the glomerular by the way of the EA
What maintains the osmarity of blood
Plasma proteins and salt
Diuretics
Chemicals that increase the flow of urine
