Question

Match circulatory terms with the correct descriptions

Refers to the myocardium's ability to stretch and contract in response to filling of the heart with blood	Answer Afterload Cardiac contractility Preload Stroke volume
Causes stretch and increased pressure within the ventricles, which increases stroke volume	Answer Afterload Cardiac contractility Preload Stroke volume
This volume originates in the venous system	Answer Afterload Cardiac contractility Preload Stroke volume
The amount of blood within the ventricle that is ejected with each contraction	Answer Afterload Cardiac contractility Preload Stroke volume
Can also be called the ventricular end diastolic volume	Answer .Afterload Cardiac contractility Preload Stroke volume
Volume of blood in the heart at the end of diastole	Answer Afterload Cardiac contractility Preload Stroke volume
The amount of resistance the ventricle must overcome in order to pump blood out of the heart	Answer. Afterload Cardiac contractility Preload Stroke volume
Can be affected by the stretch of the heart chambers, afterload, and the autonomic nervous system	Answer Afterload Cardiac contractility Preload Stroke volume
Is increased by high pressure in the aorta and systemic hypertension	Answer Afterload Cardiac contractility Preload Stroke volume

Answer 1

1.cardiac contractility

Myocardium's ability to stretch and contract in response to filling of heart with blood

2.Preload

It causes stretch and increased pressure within ventricles which increases stroke volume

3.Preload

This volume orginates in the venous system

4.Stroke volume

Amount of blood within ventricles that is ejected with each contraction.

5.Preload

Can also be called ventricular end diastolic pressure.

6.Preload

Volume of blood in the heart at the end of the diastole.

7.Afterload

Amount of resistance that heart must overcome in order to pump blood out of heart.

8.Cardiac contractility

Can be affected by the stretch of heart Chambers, afterload and autonomic nervous system

9.Stroke volume

is increased by high pressure in aorta and systemic hypertension.

10.Afterload

Most commonly describes workload of left ventricles.
