mapighian

structure of urinary system (human)
Paired kidneys
Ureters
Bladder
Urethra
function of urinary system (human)
Filtration
Reabsorption
Secretion
components of kidney
renal cortex
renal medulla
nephrons
antidiuretic hormone (ADH)
controls the water permeability of the distal tubule and collecting duct, the release of this hormone is triggered by the hypothalamus when dehydration is detected.
overveiw of photonephridia
filter the interstitial fluid in flatworms. Tubules branch throughout the body tipped with flame cells that create current.
overveiw of mapighian
Mapighian tubules absorb waste in hemolymph and move it to the rectum.
overveiw of nephridia
The body cavity (coelom) filled with interstitial fluid absorbs waste from the blood. The waste is excreted through the nephridiopore.
what is nephron made from
renal corpuscle
renal tubule
what is the renal corpuslce made from
Glomerulus is a tuft of capillaries
Glomerular capsule which is cup shaped to collect to filtrate
what is the renal tubule made from
Proximal tubule,
loop of Henle (nephron loop)
Distal tubule and Collecting duct
osmoregulation
The process of maintaining osmolarity (the concentration of ions and solutes in the blood plasma)
