Answer 1

Answer:

What is the composition of urine ?

Ans. It consists of water, urea (from amino acid metabolism), inorganic salts, creatinine, ammonia, and pigmented products of blood breakdown, one of which (urochrome) gives urine its typically yellowish colour.

Are glucose and amino acids normally present in urine Why

Ans.  glucose and amino acids should be kept in the blood. These components should not be present in urine. water and salt is needed by the body and will remain in the blood.

How is volume of urine regulated?​

Ans. Urine volume and concentration is regulated through the same processes that regulate blood volume. Antidiuretic hormone (ADH)—produced by the posterior pituitary gland —increases the amount of water reabsorbed in the distal convoluted tubule and collecting duct.Aug 13, 2020

Urine is often used as a diagnostic feature for many disease conditions. These may b based on either physical or chemical components, that may give insight to processes within the body, often through urinalysis, a common clinical analysis of urine.

Physical Characteristics

Physical characteristics that can be applied to urine include color, turbidity (transparency), smell (odor), pH (acidity – alkalinity) and density. Many of these characteristics are notable and identifiable by by vision alone, but some require laboratory testing
