Question

Increasing contractility shifts the force-velocity curve to the (right or left) and (increases or decreases) Vmax.

A) Right, increases
B) Right, decreases
C) Left, increases
D) Left, decreases

Answer 1

Increasing contractility shifts the force-velocity curve to the left and increases Vmax.

Step-by-step explanation:

Increasing contractility shifts the force-velocity curve to the left and increases Vmax. This means that when contractility increases, the force produced by the heart muscle during a contraction decreases, causing the curve to shift to the left. Additionally, increasing contractility also increases Vmax, which is the maximum velocity of contraction. Therefore, the correct answer is C) Left, increases.
