Cardiology

What is the system in which the heart works?

Deoxygenated blood into the heart through sup vena cava & inf vena cava → RA → TV → RV→ PV→ PA → Lungs → PV → LA → MV→ LV→ AV → Aorta

What is stroke volume

The amount of blood pumped out of the hearts ventricle with each beat

what is ejection fraction

Measure of your hearts pumping strength

Cardiac Output

The volume of blood your heart pumps out per minute

What is pressure in vascular system

This is blood pressure, measure by systolic and diastolic numbers, blood pumping against vessel walls driven by a hearts pumping action

Cardiac Hypertrophy

Left ventricle gets larger and stronger, increased stroke volume

Increased stroke volume

More blood is ejected with each beat

Increased blood volume and plasma

Supports circulation and heat regulation

Frank Starling Law

stroke volume increases proportionally to the amount of blood in the ventricles

stretching the myocardial fibers during diastole improves their overlap, resulting in a stronger contraction during systole

Blood Volume

The amount of blood circulating in your entire body
