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
forms the heart apex
Left ventricle
Thing that separate the ventricles
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
arteries, arterioles, veins, venules, capillaries
aa,vv,c
Veins have thicker wall that arteries
False
Convey blood AWAY from the heart
Arteries
Convey blood back to the heart
Veins
Where does the exchange of gases and waste materials happen
Capillaries
Carries deoxygenated blood from the heart
Pulmonary Arteries
Carry oxygenated blood to the heart
Pulmonary Veins
Color of blood in the arteries
Bright red color and oxygenated
Color of blood in the veins
Dark red to bluish color and deoxygenated
Two types of Circulation
Pulmonary and Systemic Circulation
Pulmonary Circulation
Superior vena cava -> left atrium
Systemic Circulation
Left atrium -> Rest of the body then Superior vena cava ulit to right atrium
