Divisions of the circulatory system
System and Pulmonary Circulation
The function of the circulatory system
Pump oxygenated blood into the organs
Take deoxygenated blood into the lungs to oxygenate it
Blood vessels are the distribution centre
Arterial vs Venous
Arterial blood vessels carry oxygenated blood
Venous blood vessels deoxygenated blood
Systemic Circulation
Carries blood from left ventricle to distribute blood to the organs and then
carries the deoxygenated blood into the pulmonary system
Pulmonary system pumps deoxygenated blood into the lungs to oxygenate it
Pulmonary Circulation
Blood is pumped from the right ventricle into the pulmonary artery to the lungs
and gets oxygenated
Takes place in a closed loop of vessels that only carries blood between the
heart and lungs
Basics of Cardiac Physiology 1
, Anatomy of the heart
Heart Chambers(Myocardium)
Left and Right Atrium
Left and Right ventricle
Why is the left ventricle more muscular?
Left ventricle is more muscular as it has to pump the blood further(Thicker wall)
Atria of the heart
Receiving chambers
Enters through the right atrium from the superior and inferior vena cava
Blood enters the left atrium from the pulmonary vein
Ventricles
Discharging chambers
Right ventricle pumps blood through the pulmonary artery
