CARDIOVASCULAR SYSTEM
The left ventricle pumps oxygenated blood into which of the following structures:
ascending aorta
anterior interventricular sulcus
The anterior interventricular branch of the left coronary artery runs in it along with the great cardiac vein.
Where is the heart located?
mediastinum the cavity between lungs
which blood component is chiefly responsible for oxygen transport?
red blood cells
inferior vena cava
a large vein that carries venous blood from the lower body to the right atrium
This structure carries deoxygenated blood from the upper half of the body (above the diaphragm) to the heart
superior vena cava
Which bone covers and protects the anterior side of the heart?
The sternum
Identify the aortic arch
B
ascending aorta
Branches off the left ventricle; carries oxygen rich blood to parts of the body above the heart
What is the name applied to the narrow, inferior end of the heart that protrudes into the left lung?
The apex
what structures are made by the body's white blood cells that fight bacterial infection?
Antibodies
Approximately how much of the heart's mass lies to the left of the body?
Approximately two thirds
Which of the following is correct regarding the flow of blood in reference to the left side of the heart?
Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, through the aortic semilunar valve, and then into the aortic arch.
Which of the following is correct regarding blood flow in reference to the right side of the heart?
Blood flows from the right atrium through the tricuspid valve, into the right ventricle, through the pulmonary semilunar valve, into the pulmonary trunk, and then into the pulmonary arteries.
The bottom portion of the heart is anchored to which organ?
The diaphragm
Name the compartment (or space between the lungs that contains the heart
The mediastinum
If the pressure in the pulmonary artery is increased above normal, which chamber of the heart will be affected first?
The right ventricle
superior vena cava
analogous structure to the inferior vena cava in the upper part of the body. It also drains into the right atrium.
This groove is situated on the sternocostal surface of the heart:
anterior interventricular sulcus
Which of the following is also known as the mitral valve?
bicuspid
Which of the following structures gives rise to the right subclavian artery:
brachiocephalic trunk/ innominate artery
This structure carries deoxygenated blood from the lower limbs and abdominopelvic region to the heart:
inferior vena cava
The right ventricle is the chamber of the heart that pumps blood for the pulmonary circulation. Based on this information, blood from the right ventricle is on its way to the
lungs
What is the heart surrounded by?
pericardium
Which of the following structures carries deoxygenated blood from the heart to the lungs:
pulmonary trunk/ main pulmonary artery
main pulmonary artery
riginates from the right ventricle and splits into right and left pulmonary arteries.. carried blood from right ventricle to lungs
What is the name applied to the broad, superior end of the heart that attaches to the major blood vessels?
the base
brachiocephalic trunk/ innominate artery
which supplies the right arm, head, and neck with blood
