Lecture Exam 3 - Structure of the Heart Flashcards
• The right side of the heart (the pulmonary circuit) sends blood through the pulmonary circuit to send blood to____
(to the entire body / in the systemic circuit)
• What is the difference between the atria vs the ventricles?
The atria is where blood is received where the ventricles is where blood is pumped)
• The right atrium receives___
deoxygenated blood from the superior vena cava & inferior vena cava
• What does the superior vena cava do?
(Drains blood from the jugular that comes from the brain)
• What is the inferior vena cava?
which drains blood from the veins that come from the lower organs and legs
• The right atrium also receives_____
receives blood from the coronary sinus which drains deoxygenated blood from heart itself
• After the coronary sinus drains deoxygenated blood, it passes the right ventricle through the ____
atrioventricular vale/tricuspid vale, which opens to prevent backflow of blood
• The atrioventricular valve prevents what?
backflow back to the heart
• The valve separating the chambers on the left side of the heart valve is called
the mitral valve
• After the Right Ventricle is ____
the right ventricle pumps blood, by-passing the Semilunar Valve and then pumps through the pulmonary trunk going through the pulmonary arteries – then to the lungs
• Once the right ventricle pumps blood through the pulmonary arteries
by-passing the Semilunar Valve) the semilunar valves close preventing what? blood backflowing to the right ventricle
• The left atrium then receives oxygen-rich blood from the lungs via
the pulmonary veins
• Once the left atrium receives Oxygen-rich blood from the lungs via the Pulmonary veins, this same blood then passes through the
Mitral valve – the atrioventricular valve on the left side
• After oxygen-rich blood is pumped through the mitral valve, the left ventricle is where blood is pumped through the what?
(The Aorta to the rest of the body)
