Question

explain where and how urin in produced
​

Answer 1

Answer:

Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.

Answer 2

Answer:

Blood passes through filtration units in the kidney called nephron

- Passes through glomerulus in the Bowman's capsule - Ultra

filtration

- Filtrate initially has glucose, amino acids, water, salts and

nitrogenous waste

- Reabsorption – Water (as per the need of the body), Glucose and

amino acids are all reabsorbed –

- Secretion of excess water, salts and urea (nitrogenous waste)

which makes up the urine
