Answer 1

1. Renal Artery: It provides oxygenated blood to the kidney muscles.
2. Urethra: Urine can pass through this tube and leave the body.
3. Glomerulus: It serves as a blood filter by removing the nitrogenous wastes from the blood.
4. Tubular part of nephron: The necessary salts and water content from the filtered blood are absorbed and reabsorbed with its assistance. As a result, they preserve the blood's osmolarity.
