Structure Of The Heart & The Path Of Blood Through The Heart Flashcards
Is the pulmonary circuit on the left or right side of the cardiac muscle?
The pulmonary circuit is on the right side of the cardiac muscle
- left side on paper
- coloured blue
Is the systemic circuit on the left or right side of the cardiac muscle?
The systemic circuit is on the left side of the cardiac muscle
- right side on paper
- coloured red
Describe the left side of the cardiac muscle :
The left side of the cardiac muscle has a thicker muscular wall which allows it to contract with more force to circulate oxygenated blood from the lungs through the large systemic circuit to the muscles and organs
Describe the right side of the cardiac muscle :
The right side of the cardiac muscles contracts to circulate deoxygenated blood from the body through the pulmonary circuit to the lungs
What lies between the atria and ventricles?
The atrioventricular valves (AV) lie between the atria and ventricles
What does the semi-lunar (SL) valves do?
The semi-lunar valves prevent backflow of blood
What is oxygenated blood?
Oxygenated blood is blood saturated with oxygen and nutrients such as glucose
What is deoxygenated blood?
Deoxygenated blood is blood depleted of oxygen and saturated with waste products such as carbon dioxide
What path does the blood take on the left side of the heart?
*systemic circuit
Oxygenated blood moves though the LEFT atria —> through the LEFT AV valve (bicuspid) —> into the LEFT ventricle and forced out of the LEFT side of the heart into the aorta, which carries The OXYGENATED blood to the muscles and organs
What path does the blood take on the right side of the heart?
*pulmonary circuit
Deoxygenated blood moves through the right atria —> through the right AV valve (tricuspid) —> into the right ventricle and forced out of the RIGHT side of the heart into the pulmonary artery, which carries the DEOXYGENATED blood back to the lungs
