PLTW PBS Heart Flow
Terms in this set (22)
Superior and inferior vena cava
Order of blood flow
receives oxygenated blood from the lungs
Receives deoxygenated blood from the body
superior and inferior vena cava
veins that carry deoxygenated blood to the right atrium from the body
The large arterial trunk that carries blood from the heart to the body
carry the oxygenated blood from the lungs into the left atrium of the heart
carry deoxygenated blood out of the right ventricle and into the lungs
amount of leaflets by tricuspid valve
What happens to the leaflets as you tug on the chordae tendinae?
Forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava. These are large veins that transport deoxygenated blood from the body back to the heart. Blood collects within the right atrium, and it must flow through the tricuspid valve in order to enter the right ventricle
tricuspid valve function
Higher forces are needed to pump blood through the heart
Why is the left ventricle thinner than the right?
It permits blood to flow one way only, from the left atrium into the left ventricle
Bicuspid Valve Function
two leaflets, looks like a bishops miter, and on the left side of the heart
Describe the appearance of the bicuspid valve
Thicker than all the other veins and arteries
How thick is the aorta?
Arteries have thicker walls than veins because they are closer to the heart and receive blood that is surging at a far greater pressure than veins. Veins withstand a much lower pressure from the blood that flows through them.
Why are arteries thicker than veins?
Arteries- thicker wall, rounder, no valves, carry blood away from the heart
Veins- thinner wall, more worm-like, usually flattened, contain valves, carry blood back to the heart
Veins V Arteries
What medication was Anna taking and why?
Reasoning- she has mirital valve prolapse
What is the machine in her heart and why does she have it?
When the leaflets in the mirital valve swell and bulge into the left atrium. Can cause blood to go backwards from the ventricle to the atrium or an irregular heartbeat.
mirital valve prolapse
The swelling of the walls (septum) of the left ventricle causing it to become smaller
Left Ventricle hypertrophy
high blood pressure
What can cause left ventricle hypertrophy
it fails to pump blood into the aorta so blood can not get to the body causing the whole blood flow circuit to be off
Why can left ventricle hypertrophy be fatal
