(N/A) $(1)$ Malpighian Body: It is a complex structure formed of the glomerulus and Bowman's capsule.
$(i)$ Glomerulus: It is a tuft of capillaries formed by the afferent arteriole,which is a fine branch of the renal artery. Blood from the glomerulus is carried away by the efferent arteriole.
The diameter of the efferent arteriole is smaller than that of the afferent arteriole. Blood is filtered in the glomerulus.
$(ii)$ Bowman's Capsule: One side of the closed uriniferous tubule invaginates to form a cup-shaped,double-walled sac-like structure known as Bowman's capsule.
The outer wall of Bowman's capsule is formed of squamous epithelium,while the inner side possesses specific cells called podocytes. These cells are arranged in a special manner to form filtration slits (pores),which allow molecules to pass through them.
Bowman's capsule and the glomerulus together are termed the Malpighian body.
