Read each question carefully and answer to the best of your ability. Refer to the diagram of the nephron where indicated.
The diagram below illustrates the structure of a nephron. Use it to answer the following questions.
1. Which part of the nephron is primarily responsible for the filtration of blood?
Loop of Henle
Glomerulus
Collecting Duct
Distal Convoluted Tubule
2. Reabsorption of most filtered substances, such as glucose and amino acids, occurs in which part of the nephron?
Proximal Convoluted Tubule
Bowman's Capsule
Loop of Henle
Collecting Duct
3. The fluid filtered from the blood in the glomerulus is called .
4. The hormone regulates water reabsorption in the collecting duct.
5. Briefly describe the three main processes involved in urine formation within the nephron.
6. Explain the role of the Loop of Henle in creating a concentration gradient in the renal medulla.
7. All substances filtered out of the blood by the glomerulus are eventually excreted in the urine.
True
False
8. The efferent arteriole carries blood away from the glomerulus.
