Where does gas exchange occur in the lungs?
Press to flip
In the alveoli sacs and capillaries.
Which vessel carries blood from the right ventricle to the lungs?
The pulmonary artery.
Through which veins does deoxygenated blood enter the right atrium?
The superior vena cava and the inferior vena cava.
What distinguishes the pulmonary artery from other arteries?
It carries deoxygenated blood, unlike most arteries which carry oxygenated blood.
What is the main function of the left side of the heart?
Distributing oxygenated blood throughout the body.
What role does the left ventricle play in systemic circulation?
It pumps oxygenated blood through the aortic valve into the aorta for distribution.
Which valve must blood pass through as it leaves the left ventricle to enter the aorta?
The aortic valve.
What valve does blood pass through to move from the right atrium to the right ventricle?
The tricuspid valve.
What is the major artery that distributes oxygenated blood to the body from the left ventricle?
The aorta.
What is the importance of understanding the sequence of valves in the heart?
It is crucial for mastering the blood flow of the heart.
Through which valve does blood pass from the left atrium to the left ventricle?
The bicuspid (mitral) valve.
What is absorbed and expelled during gas exchange in the lungs?
Oxygen is absorbed, and carbon dioxide is expelled.
How does oxygenated blood return to the heart from the lungs?
It returns via the pulmonary vein to the left atrium.
What is the primary function of the right side of the heart?
The right side of the heart transports deoxygenated blood to the lungs.
What is the mnemonic you can use to remember the sequence of valve passage in the right side of the heart?
Try before you buy, referring to the tricuspid valve.
