Answer

a. increase Explanation 1. Understand the relationship Blood flow is determined by the formula **Q = \frac{\Delta P}{R}**, where Q is blood flow, \Delta P is the pressure difference, and R is the resistance. 2. Analyze the effect of decreased resistance If total peripheral resistance (R) decreases and pressure difference (\Delta P) remains constant, then according to the formula, blood flow (Q) will increase.

Explanation

1. Understand the relationship<br /> Blood flow is determined by the formula **$Q = \frac{\Delta P}{R}$**, where $Q$ is blood flow, $\Delta P$ is the pressure difference, and $R$ is the resistance.<br />2. Analyze the effect of decreased resistance<br /> If total peripheral resistance ($R$) decreases and pressure difference ($\Delta P$) remains constant, then according to the formula, blood flow ($Q$) will increase.
