Structure Of The Heart Flashcards
Vena Cava (top left)
Carries deoxygenated blood to right atrium
Pulmonary artery (top, middle left)
Carries deoxygenated blood to the lungs to collect oxygen
Pulmonary vein (top right)
Carries oxygenated blood from the lungs to left atrium
Aorta (top, middle right)
Carries oxygenated blood around body to respiring cells
Valves
Prevent blood flowing backwards
Septum (middle)
Middle of heart that separates left and right and stops oxygenated and deoxygenated blood mixing
Thick left ventricular wall (bottom right)
Pumps blood long distance around body
Thin right ventricular wall (bottom left)
Pumps blood short distance to lungs
Muscular ventricular walls
Pumps blood around body
Right atrium
Top left of heart
Left atrium
Top right of heart
Vena cava pumps deoxygenated blood to
Right atrium
Right atrium pumps blood to
Right ventricle when the atrial walls contract
The blood is pumped to the lungs via the
Pulmonary artery
Blood is oxygenated in lungs from gas exchange and returns to the
Left atrium via pulmonary vein
