Question

1-name the substances selectively reabsorbed by nephron.
2-main blood vessels from which blood enters and leave kidneys.
3-part of nephron where ultrafiltration takes place.
4-part of nephron where selective reabsorption takes place.​

Answer 1

Answer:

1. Urea from collecting tubule and water and NaCl from distal convoluted tubule or DCT are selectively reabsorbed through active means in nephrons.

2. Renal Artery and Renal Vein are the major blood vessels through which blood enters and leaves the kidney respectively.

3. Ultrafiltration occurs in Malphigian body, also known as Renal Corpuscle which consists of PCT, DCT Bowman's capsule, afferent and efferent arteriole.

4. Selective reabsorption occurs in DCT and collecting tubule.
