Answer 1

$\bold{KIDNEY}$

Kidneys are two bean shaped primary excretory organs of the excretory system.

$\bold{Parts \: of \: kidney}$

▶Kidney is made up of two primary regions

✳Medula , a lighter region consisting of striped like conical structures called conical pyramid and their apex is called papilla.

✳Cortex ,the outer dark region .

▶Each kidney consist its fundame unit nephron whose, parts are according divided among cortex and medulla.

▶Cortex regjon have Bowman's capsule and proximal convoluted tubule of nephron which gives it a dotted appearance.

▶Medulla region consist loop of henle and distal convoluted tubule.

▶The urine after going through ultrafiltration , reabsorbtion anf tabular secretion enters into collecting tubule.

Which then enters into urethra by ureter and then is expelled out by mituration .

Answer 2

While drawing a longitudinal structure of the kidney, you need to make sure that the kidney is formed in a bean like structure with three pipes like structure falling out of it which will be termed as a renal vein, renal artery and ureter. Then draw kidney cortex, interlobular artery, interlobular vein and renal capsules.
