Structure and Function of the Heart Unit 2 Flashcards
Name the 4 chambers of the heart
- Right Atrium
- Left Atrium
- Right Ventricle
- Left Ventricle
Which type of blood vessel carries blood towards the heart ?
Veins
Which type of blood vessel carries blood away from the heart ?
Arteries
Name the blood vessel that carries deoxygenated blood from the body back to the heart and enters the right atrium ?
Vena Cava
Name the chamber that blood travels to from the right atrium ?
Right ventricle
Name the valve through which blood travels as it goes from the right atrium to the right ventricle ?
AV Valve (Atrio-Ventricular Valve)
What does the AV valve on the right side of the heart prevent ?
Backflow of blood from the right ventricle to the right atrium
Blood travels to the lungs from the right ventricle through which blood vessel ?
Pulmonary Artery
As blood travels from the right ventricle to the pulmonary artery, name the valve that it passes through
Semi-lunar valve
What does the semi-lunar valve on the right side of the heart prevent ?
Backflow of blood from the pulmonary artery to the right ventricle
What does blood travelling to the lungs from the pulmonary artery pick up at the lungs ?
Oxygen
What name is given to blood rich in oxygen ?
Oxygenated blood
What name is given to blood low in oxygen ?
Deoxygenated blood
Name the blood vessel that returns blood to the left atrium of the heart from the lungs
Pulmonary vein
Is the blood returning the left atrium oxygenated or deoxygenated ?
Oxygenated
What chamber does blood from the left atrium go to ?
Left ventricle
Name the valve present between the left atrium and left ventricle
AV Valve
What does the AV valve on the left side of the heart prevent ?
Backflow of blood from the left ventricle to the left atrium
Which ventricle wall is thicker and why ?
Left ventricle wall because it has to withstand the pressure of blood travelling to all round the body from here, whereas blood leaving from the right ventricle is only travelling a relatively short distance to the lungs, so is not under as much pressure
Blood travels from the left ventricle out of the heart through which blood vessel ?
Aorta
Name the valve present between the aorta and the left ventricle
Semi-lunar valve
What does the semi lunar valve on the left side of the heart prevent ?
Backflow of blood from the aorta to the left ventricle
Name two veins associated with the heart
Vena cava and pulmonary vein
Name the two arteries associated with the heart
Pulmonary artery and aorta
What is unique about the pulmonary artery and pulmonary vein
They are the only artery and vein in the body that switches the rule regarding arteries farting oxygenated blood and the veins carrying deoxygenated blood. PA carries deoxygenated blood and PV carries oxygenated blood
