Verified answer
Answer:
Option 1. Glomerular filtration, reabsorption and tubular secretion
Explanation:
1.Gomerular filtration occur in glomerulus. There blood is filtered which reach Bowman’s capsule, except proteins.
2. Around 99% of the filtrate is reabsorbed by the renal tubules. This process is called reabsorption..
3.In secretion process tubular cells secrete substances like hydrogen ions, potassium ions, etc into the filtrate.These ions combine with the filtrate and form urine. The urine passes out of the nephron tubule into a collecting duct.
