blood cells and plasma proteins
the high-pressure of ultrification is created by…
the glomerulus have a wide afferent arteriole and narrow efferent arteriole
the surface area for filtration is increased by…
narrow branches formed by the glomerulus
osmoregulation
the control of water and solute concentrations in body fluid
osmoregulation takes place in the…
