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

Answer:

GM FRIEND

Explanation:

Ans(1), Nitrogenous waste is excreted in different forms by different species. These include (a) ammonia, (b) urea, and (c) uric acid.

Ans(2),

The kidneys

Materials eliminated via the kidney include nitrogenous waste products (ammonia, uric acid, urea, creatine, creatinine, and amino acids), excess quantities of salts and water that may be taken into the body, and various other organic materials produced by life-sustaining chemical reactions.

Ans(3), They include waste material such as sand, salt, Iron, Calcium, and other mineral materials that are only slightly affected by the action of organisms.

Ans(4), The urinary system consists of the kidneys, ureters, urinary bladder, and urethra.

Ans(5),

a renal tubule that processes and carries away the filtered fluid.

• Renal corpuscle.
• Glomerulus.
• Bowman's capsule.
• Renal tubule.
• Length difference.
• Proximal tubule.
• Loop of Henle.
• Distal convoluted tubule.

Ans(6), Filtration, Reabsorption, Secretion: The Three Steps of Urine Formation. The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion.

Ans(7), The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.

Answer 2

Answer:

1. three nitrogenous wastes of our body are ammonia urea uric acid
2. three organic waste of our body are urea uric acid and creatinine
3. three inorganic wastes of our body are salt that is sodium chloride potassium chloride and ammonia
4. three main parts of urinary system are kidney urinary bladder urethra
5. 6 main parts of nephron are bowman's capsule, glomerulus, proximal convoluted tubule distal convoluted tubule loop of henle and collecting duct
6. three stages of urine formation is ultrafiltration reabsorption and tubular secretion
