(1ai)
Glomerulus:
(PICK ANY ONE)
(i) It filters blood to form glomerular filtrate.
(ii) It removes waste products and excess substances from the bloodstream.
(iii) It initiates the urine formation process by allowing water and small molecules to pass through while retaining larger molecules like proteins.

(1aii)
Bowman’s capsule:
(PICK ANY ONE)
(i) It collects the filtrate produced by the glomerulus.
(ii) It forms primary urine by capturing the filtrate and directing it into the nephron.
(iii) It serves as a funnel, guiding the filtrate into the proximal convoluted tubule for further processing.

(1aiii)
Proximal convoluted tubule:
(PICK ANY ONE)
(i) It reabsorbs water, ions, and nutrients from the filtrate back into the bloodstream.
(ii) It plays a crucial role in secreting waste products such as hydrogen ions and ammonia into the tubular fluid.
(iii) It maintains pH balance by selectively reabsorbing bicarbonate ions and secreting hydrogen ions.

(1aiv)
Distal convoluted tubule:
(PICK ANY ONE)
(i) It reabsorbs sodium and water, thus playing a key role in regulating blood pressure and fluid balance.
(ii) It secretes potassium and hydrogen ions, which helps in maintaining electrolyte and acid-base balance.
(iii) It also regulates calcium and phosphate levels in the blood, contributing to bone health and metabolic functions.
