the filtrate travels through the renal tubule and useful substances are reabsorbed into the blood.
blood enters the kidneys through the renal artery and branches to reach the glomerulus.

Explanation:

Urine formation starts with blood entering the kidneys, followed by filtration in the Bowman's capsule, then reabsorption of useful substances, and finally secretion of additional wastes into collecting tubules.

Answer:

1. Blood enters the kidneys through the renal artery and branches to reach the glomerulus.
2. Pressure of the blood forces water and dissolved substances through capillaries and into the Bowman's capsule.
3. The filtrate travels through the renal tubule and useful substances are reabsorbed into the blood.
4. Nephron tubules secrete waste products into collecting tubules.
