Question

Urea is formed by deamination of amino acids in the liver, and then it is transported by the blood to the kidneys where it is excreted in urine (harvey et al., 2011).

Answer 1

amino acids are toxic for our body and no longer store in the liver. Therfore,excess amino acids are delaminated and convert into urea which is less toxic in nature and then it is transported by the blood to the kidneys where it undergoes through ultrafiltration , selective reabsorption and tubular secretion After that it passes through uterus and further store into the urinary bladder temporally and passes through urethra in form of urine with other wastes.
