TEAS 7 - Science (Cardiovascular System) Flashcards
This is the largest artery in the body.
aorta
The heart pumps blood from the ___ ventricle into the aorta through the ____ valve.
left
aortic
The ___ ___ ___ is ultimately responsible for the transport of almost all venous blood from the abdomen and lower extremities. It carries deoxygenated blood back to the right side of the heart for oxygenation.
inferior vena cava
What kind of blood does the inferior vena cava carry?
deoxygenated
One of four chambers of the heart that receives blood full of oxygen from the lungs and then empties blood into the left ventricle
left atrium
one of the four chambers of the heart that pumps blood full of oxygen out to the body
left ventricle
this valve is one of four valves in the heart and is located on the left side of the heart and sits between the left atrium and ventricle
mitral (bicuspid) valve
What is the term used to describe the flaps (leaflets) in the heart that open and close once during each heartbeat to keep blood flowing in the right direction?
valves
The ___ artery carries blood from the right side of the heart to the lungs.
pulmonary
The pulmonary system (or circulation) is the movement of ___ from the heart to the ___ and back to the heart. It is a closed circuit.
blood
lungs
The ____ valve is one of two valves that allow blood to leave the heart via the arteries. This valve opens into the pulmonary artery allowing deoxygenated blood to leave the heart to travel to the lungs.
pulmonary
one of the four chambers of the heart that receives blood low in oxygen from the body and empties blood into the right ventricle
right atrium
one of the four chambers of the heart that receives oxygen-poor blood from the right atrium and pumps oxygen-poor blood to the lungs through the pulmonary valve
right ventricle
The ___ vena cava carries oxygen-poor blood from the head, neck, arms, and chest into the right atrium.
superior
The systemic system (or circulation) is the movement of ___ from the heart to the rest of the ___ (besides the lungs) and back to the heart.
blood
body
The ___ valve sits between the heart’s two right chambers and consists of three thin flaps of tissue. It opens to let blood flow from the right atrium to the right ventricle.
tricuspid
The ___ circuit is the pathway of blood from the heart to and from the lungs.
pulmonary circuit
___ blood is pumped by the right side of the heart to the lungs for ____, then returns to the left side of the heart.
deoxygenated
oxygenation
The ___ circuit is the pathway of blood from the heart to the rest of the body.
systemic
___ blood is pumped from the left side of the heart to the body and ___ blood returns to the right side of the heart.
oxygenated
deoxygenated
The heart essentially has 2 jobs: it pumps ____ blood from the body to the lungs and pumps ___ blood from the lungs to the heart and then the body.
deoxygenated
oxygenated
The heart is divided into 2 sides (right and left), each performing its own job. The right side moves blood from the ___ to the ___, and the left side moves blood from the ___ to the ___.
body, lungs
lungs, body
Of the two jobs that each side of the heart performs, one of the two jobs is difficult. Since the heart is closer to the lungs, the job of the right side of the heart is ___. The job of the left side of the heart is ___ because blood must be pushed out to the remainder of the body. Transporting blood farther makes the job harder, and this is why the ___ side of the heart is larger than the ___ side of the heart.
easier
harder

The adult heart is located in the ___ cavity.
