Circulatory System Flashcards
made up of heart, blood and vascular system
Circulatory System
Heart is made up of cardiac muscles that is volountary
False
Blood flow in heart
Superior vena cava -> right atrium -> tricuspid valve -> right ventricle -> Pulmonary artery -> lungs -> pulmonary vein -> left atrium -> mitral valve -> left ventricle -> diff parts of body

Interventricular Septum
The muscle of the ventricle is thicker than the atrium
True
Right ventricle is thicker than the left ventricle
False
Prevent the backflow of blood
Valve
The one that regulates the rhythmic contraction of heart
Sino-Atrial node (SA NODE) / Pacemaker
Pacemaker kasi kapag may irregular heartbeat sinsignal niya ang heart (thru atriventricular bundle -> purkinje fiber) para bumalik sa normal heartbeat.
Serve as the network that conveys blood all through out the body
Blood Vessels
made up of smooth muscle that are capable of vasomotion (vasoconstriction and vasodilation)
Blood Vessels
Enumerate the blood vessels
