* Glomerulus It is a tuft of capillaries formed by the afferent arteriole (a fine branch of renal
artery).
The afferent arteriole is short and wide that supplies blood to the glomerulus, while, the
efferent arteriole is narrow and long carrying blood away from the glomerulus.
Differences between Afferent Arteriole and Efferent Arteriole

ii. Bowman’s Capsule (Glomerular capsule) It is a double walled cup-like structure that
surrounds the glomerulus. The outer parietal wall which is composed of flattened
(squamous) cells and the inner visceral wall is composed of a special type of less flattened
cells, called podocytes.
