4. The purpose of urine formation in our body is to remove waste products from the blood.
5. A. Urinary Bladder, B. Nephrons, C. Renal artery and D. Urethra.
6. The blood enters the kidneys through renal arteries. They pass through the bowman's capsule, where the waste products are removed with the help of the glomerulus in the bowman's capsule. The waste products removed by glomerulus pass through the tubular part of the nephron which includes proximal covulated tubules and distal convoluted tubules. There is also presence of the capillaries on the tubules, which reabsorbs of the nutrients and water from the waste products removed by glomerulus. Hence, the waste products at last, is collected in the collecting duct, which further is removed through the ureters, and finally collected in urinary bladder. At last, the urine of the waste product is removed through urethra.
