Question

1. Describe the mechanism of excretion in kidney.​

Answer 1

Answer:

kidney

Explanation:

The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The filtrated blood is carried away from the kidneys by the renal vein (or kidney vein)

Answer 2

• The kidneys excrete waste, primarily urea, through urine. Amino acids are formed when proteins are digested, and urea is formed as a by-product of ammonia breakdown.
• The urea-containing blood (blood filtrate) is transported from the liver to the kidneys, where it is excreted as urine.
• It takes a long time for urine to develop from blood filtrate.

• The kidneys filter nitrogenous wastes like urea, as well as salts and excess water, from the bloodstream and excrete them as urine.
• The kidney's nephrons, which number in the millions, aid with this.
• The renal vein transports the filterated blood away from the kidneys (or kidney vein).
