Question

question 17 (2 points) arterial pressure in the pulmonary circulation is much higher than in the systemic circulation because of its proximity to the heart. false true question 18 (2 points) which of the following is the most significant source of blood flow resistance? blood viscosity blood vessels type total blood vessel length blood vessel diameter

Explanation:

For Question 17: Arterial pressure in pulmonary circulation is lower than in systemic circulation due to the lungs' low - resistance circuit. So the statement is false.
For Question 18: Blood vessel diameter is the most significant factor affecting blood flow resistance as per Poiseuille's law. Small changes in diameter can cause large changes in resistance.

Answer:

Question 17: A. False
Question 18: D. blood vessel diameter
