Choose the correct pathway for the flow of blood:
Correct answer: A. Arterioles → metarterioles → capillaries → thoroughfare channels
- A. Arterioles → metarterioles → capillaries → thoroughfare channels
- B. Arterioles → thoroughfare channel → metarterioles → capillaries
- C. Metarterioles → arterioles → thoroughfare channels → capillaries
Explanation
Explanation: Option B, C and D are incorrect because there is only one proper pathway for blood flow which is from Arterioles⇨Metarterioles⇨Capillaries. ⇨Thoroughfare channels As mentioned above, Option A is the correct answer. Diagram shown below also helps to explain this pathway. The arrows in the diagram show active blood flow.
