Question
Identify the blood vessel with the greatest total cross-sectional area Select one O a, veïns b. arterioles c. arteries O d. capillaries Select the correct statement about the kidneys: Select one O a. The collecting ducts of the kidneys are found embedded in the renal cortex. O b. Each Bowman's capsule contains up to four nephrons O c. The collecting duct of the kidney drains into the urethra O d. The human kidney has millions of nephrons All of the following factors contribute to the further concentration of the filtrate as it travels through a nephron and becomes urine except Select one O a. active transport of urea into the ascending loop of Henle b. active transport of NaCI out of the ascending loop of Henle ( C. three countercurrent exchange sections of the nephron O d. osmosis of water out of the descending loop of Henle and collecting tubuleExplanation / Answer
1) The correct option is d. Capillaries .
Capillaries are the largest total cross-sectional area of blood vessels.
2) The correct option is d. The human kidney has millions of nephrons.
Each kidney has million filtering units, which are known as nephrons.
3) The correct option is a. active transport of urea into the ascending loop of Henle.
The active transport of sodium chloride not urea out of the ascending limb, which ncreases the interstitial osmolality and decrease the osmolality of the fluid within the ascending limb.
