Observe the diagram of the nephron below and answer the following questions.
1. Label the following parts of the nephron on the diagram above:
a. Glomerulus
b. Bowman's Capsule
c. Proximal Convoluted Tubule
d. Loop of Henle
e. Distal Convoluted Tubule
f. Collecting Duct
2. Which of the following is the primary site of filtration in the nephron?
Loop of Henle
Collecting Duct
Glomerulus
Distal Convoluted Tubule
3. What is the main function of the Loop of Henle?
Blood filtration
Reabsorption of water and salt
Secretion of waste products
Urine storage
4. The process by which substances are moved from the blood into the filtrate in the renal tubule is called .
5. The fluid that enters Bowman's capsule from the glomerulus is called the .
6. Antidiuretic hormone (ADH) primarily affects the permeability of the and to water.
7. All substances filtered out of the blood by the glomerulus are eventually excreted in the urine.
True
False
8. The nephron is the functional unit of the liver.
True
False
9. Briefly explain the three main processes of urine formation that occur in the nephron.
10. How does the structure of the glomerulus and Bowman's capsule facilitate efficient filtration?
