Question

4. Name the following:
(a) Three nitrogenous wastes of our body.
(b) Three organic wastes of our body.
(c) Three inorganic wastes of our body.
(d) Three main parts of our urinary system.
(e) Six main parts of nephron.
(f) Three stages of urine formation.
(g) Three types of fluids in different parts of a nephron.​

Answer 1

$\huge \purple A \purple N \purple s \purple W \purple e \purple \R :-$

1. Ammonia , Urea , Uric acid

2. Creatine , Creatinine , Amino acids

3. Ammonia , Urea , Uric acid

4. kidney , ureters , urinary bladder

5. Bowman's capsule, proximal tubule, Loop of Henle, distal tubule and the collecting duct.

6. glomerular filtration, reabsorption, and secretion.

7. Juxtamedullary nephrons start low in the cortex near themedulla and have a long loop of Henle, which penetrates deeply into the renal medulla: only they have their loop of Henle surrounded by the vasa recta. The other two are water and urine glomerular filtrate.
