प्रश्न
The figure given below represents a kidney tubule in humans and its blood supply. Study the figure and answer the questions that follow. Write specific name and numbers shown in the diagram for each answer.
 |
- Name the part which consists of a knot - like mass of blood capillaries.
- What is the specific name for the combination of parts shown as 5 and 3?
- Name the part which collects the glomerular filtrate.
- Where is the most water reabsorbed?
- Name the part which collects urine in the diagram shown.
- Which part lies in the medulla of the kidney?
- Which of the above parts is involved in the process of tubular secretion?
- How is hydrostatic pressure created?
- Where does ultrafiltration take place?
- Name two important constituents of urine.
उत्तर
- Glomerulus
- Malpighian capsule
- Bowman's Capsule
- Proximal Convoluted Tubule
- Collecting Duct
- Loop of Henle and Collecting Duct
- Proximal and Distal Convoluted tubule
- The efferent (outgoing) arteriole is thinner than the afferent (incoming). This creates significant hydrostatic pressure in the glomerulus.
- Glomerulus
- Components of urine are water and solid waste (urea, creatinine, uric acid, etc.)
