A. Glycerol + phosphate group
B. 2 fatty acids
combination of glycerol + phosphate group + 2 fatty acids
controls fluidity (when under low temps, it increases fluidity; when under high temps, it decreases fluidity); helps self heal with lipids
carrier molecules; constantly moving; active and passive transport
E. lipid bilayer
boundary; not soluble in water; moves to create opening for small molecules (H2O, glucose, O2, CO2); passive transport
F. matrix or receptors
matrix: attachments that hold on; receptors: tell cell what it needs
A. renal pelvis
collects urine from nephrons
middle; contains nephrons; water is reabsorbed to balance the concentration of blood
contains parts of nephrons; blood is filtered
carries blood from renal pelvis to bladder
E. renal vein and artery
renal artery: carries unfiltered blood from heart to kidney; renal vein: carries filtered blood from kidney to heart
urine leaves body through this tube
ball of capillaries
B, D. renal artery and vein
carries blood to or from the kidney
C, F. capillary/artiole
E. loop of henle
rebalances blood; especially sodium and water (reabsorption and secretion)
G. glomerular capsule
H. collecting tubule
collects all the materials; last step of reabsorption of water (ADH)
Proximal convoluted tubule/distal convoluted tubule
reabsorption through active and passive transport
regulates secretion of H and K from blood into nephron
Does diffusion occur through veins and arteries?
NO, only capillaries
How much blood is constantly going through kidneys at any moment?
1/4 of your blood supply
antidiuertic hormone: when there is a lack of water, the pituitary gland creates more ADH. the ADH makes the cell membrane of the collecting duct more permeable to water, so more water is absorbed. this balances the water.
