Questão 26 de 50

Tubular re-absorption:
Re-absorption is the return of water and solutes to the blood following filtration. The filtrate flows
through the proximal convoluted tubules, loop of Henle, distal convoluted tubules and then to the
collecting ducts. As the filtrate moves through the nephron, much of it is reabsorbed from the
nephron to the blood stream via processes such as diffusion, facilitated diffusion, active
transport, symport and osmosis.

Renal corpuscle
The renal corpuscle consists of the ❌ (a bed of capillaries) and the glomerular ❌.
The glomerular capsule is also known as the ❌. Blood enters the ❌
(the first part of the nephron) via the ❌ arteriole. When the blood passes through the bed of
capillaries in the renal corpuscle, fluid leaves the ❌ and becomes ❌. This is the first
stage of ❌ formation. This filtrate then enters into the glomerular capsule and flows directly into
the ❌, where tubular ❌ begins. Blood that comes in via the
afferent arteriole leaves via the efferent arteriole to return to the body’s ❌ ❌
