Heart Structure Flashcards
Atria:
Receives blood returning to the heart from other areas of the body.
Ventricles:
Pump blood around the entire body.
Vena Cava:
The large vein going into the right atrium of the heart carrying deoxygenated blood from the body.
Pulmonary Arteries:
Carry deoxygenated blood from the right ventricle of the heart to the lungs.
Pulmonary Veins:
Collects the oxygenated blood and carry it from the lungs back to the heart through the left atrium.
Aorta:
Main artery that carries oxygenated blood away from your heart to the rest of your body
Valves:
Heart valves play a key role in the never-ending cycle of blood through the heart:
They keep the blood from getting lazy and retracing its journey, leaking backward into the chambers it has just left.
Tricuspid Valve:
Situated between the right atrium and right ventricle.
Consists of thin flaps of tissue which open to let blood flow from the right atrium to the right ventricle.
Bicuspid Valve:
The valveallows blood to flow from the left ventricle to the aorta and prevents blood from flowing backward.
Semi-Lunar Valve:
The twosemilunar valvesare located in the arteries allowing the blood movement from the heart to prevent it from returning back to the ventricles duringsystole.
Coronary Arteries:
Supply blood to the heart muscle
