Observe the below flow chart. Fill the boxes. Explain to which system this belongs to.

Explanation

1. Kidney 2. Loop of Henle 3 . Pelvis 4. Urethra
This flow chart belongs to excretory system in human beings. It shows the way how the blood in the kidney moves filtered and urine is excreted.
The blood is supplied to kidney by renal artery. After entering the kidney renal artery forms number of afferent arterioles . This afferent arteriole forms network of blood capillaries in Bowman ' s capsule of nephron. Blooq gets filtered in Glomerulus of Bowman's capsule . The filtered blood is kn o wn as primary urine. It passes into PCT, loop of Henle and distal convoluted tubule . After necessary reabsorption filtrate enters collecting tubule of nephron . Later filtrate enters pelvis from there it enters ureter and finally reaches urinary bladder. From urinary bladder urine is sent out of the body through urethra .
