i can not understand 11th question plz help me about it
Inner layer of bowman’s capsule is called as visceral layer lined by squamous epithelium with specialized cells called podocytes. Podocytes are connected to the basement membrane by several foot like processes. The gaps between these processes are called as filtration slits of size app.25nm. The substance now again filtrate and reach urinary space of bowman’s capsule.
the cone shaped structures are pyramids because others all are layers of kidney
good set of questions but comparitively simpler among the lot.
It’s very nice and useful
