1. Name the part which consists of a knot - like mass of blood capillaries.
2. What is the specific name for the combination of parts shown as 5 and 3?
3. Name the part which collects the glomerular filtrate.
4. Where is the most water reabsorbed?
5. Name the part which collects urine in the diagram shown.
6. Which part lies in the medulla of the kidney?
7. Which of the above parts is involved in the process of tubular secretion?
8. How is hydrostatic pressure created?
9. Where does ultrafiltration take place?
10. Name two important constituents of urine.

Answer 1

1. Glomerulus
2. Malpighian capsule
3. Bowman's Capsule
4. Proximal Convoluted Tubule
5. Collecting Duct
6. Loop of Henle and Collecting Duct 
7. Proximal and Distal Convoluted tubule
8. The efferent (outgoing) arteriole is thinner than the afferent (incoming). This creates significant hydrostatic pressure in the glomerulus.
9. Glomerulus
10. Components of urine are water and solid waste (urea, creatinine, uric acid, etc.)
