what is the relationship between the resistance to blood flow (r) and the rate of blood flow (f)? as the resistance to blood flow _, the rate of blood flow _

• increases, decreases
• there is no relationship between the resistance to blood flow and the rate of blood flow
• increases, increases

Explanation:

Analyze the relationship between pressure difference and blood flow

Using the Ohms Law of Blood Flow knowledge point

$$ F = \frac{\Delta P}{R} = \frac{P_1 - P_2}{R} $$

Since \(F\) is directly proportional to \(\Delta P\), as the difference in pressure increases, the rate of blood flow increases.

Analyze the relationship between resistance and blood flow

Using the Ohms Law of Blood Flow knowledge point

$$ F = \frac{\Delta P}{R} $$

Since \(F\) is inversely proportional to \(R\), as the resistance to blood flow increases, the rate of blood flow decreases.

• (C) There is no relationship between the difference in pressure and the rate of blood flow

Question 2

• (A) increases, decreases (Correct answer)
• (B) There is no relationship between the resistance to blood flow and the rate of blood flow
• (C) increases, increases
