Label this diagram of the heart
What is oxygenated blood?
blood saturated with oxygen and nutrients such as glucose
What is deoxygenated blood?
blood depleted of oxygen, saturated with carbon dioxide and waste products
What divides the heart into two sides
septum
What is the purpose of the septum
keep oxygenated and deoxygenated blood apart
Which side of the heart has a thicker muscular wall?
left side
Which side of the heart is the tricuspid valve?
right side
Which side of the heart is the bicuspid value?
left
What is the pathway of blood starting from when blood enters the heart from the vena cava?
vena cava → right atrium → right A-V value (tricuspid) → right ventricle → SL valve → pulmonary artery → lungs → pulmonary vein → left atrium → left A-V valve (bicuspid) → left ventricle → SL valve → aorta
What is the role of the pulmonary artery?
Carry deoxygenated blood form the heart to the lungs
What is the role of the pulmonary vein?
Carry oxygenated blood from the lungs back to the heart
What is the role of the aorta?
Carry oxygenated blood from the heart to the body
