Final answer:
Urine is released from the body soon after blood is filtered through the nephrons. So correct option is (B).
Step-by-step explanation:
The correct answer is option b) urine.
After blood is filtered through the nephrons, the waste products and excess water in the blood are removed, resulting in the formation of urine. The urine is then collected in the ureters and stored in the urinary bladder before being eliminated from the body.
This process is an important function of the kidneys in maintaining homeostasis in the body by regulating the concentration of water and solutes in the blood.
The kidneys play a critical role in filtering waste from the bloodstream. The process involves several steps, starting with blood entering the kidney and being filtered through the nephrons. Here, waste products and excess substances are removed from the blood, producing a fluid that eventually becomes urine. The blood pressure within the capillaries drives water, salts, sugars, and urea into the nephron. After filtering, the blood leaves the kidney with much less waste, while the remaining fluid in the nephron, now called urine, is collected in the ureters and stored in the urinary bladder until excretion.
