THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Venules collect the blood from the capillary bed and return it to the cortical surface. Pial veins convey the venous blood from the surface to the sinuses.

Detailed explanation-2: -Venules. A venule is an extremely small vein, generally 8–100 micrometers in diameter. Postcapillary venules drain multiple capillaries exiting from a capillary bed.

Detailed explanation-3: -Glomerular capillaries are drained by efferent arterioles whose diameter is smaller than the afferent arterioles that feed them; this creates the high blood pressure that drives filtration.
