Amazing Anatomy
What is largest artery in the body?
The aorta
Blood that is leaving the right ventricle will flow through which valve?
When the valves in the veins are leaky and blood flows backwards.
varicose veins
What structure in the heart starts the electrical impulse?
SA Node (sinoatrial Node)
What type of vessel has VALVES to prevent the back flow of blood?
veins
What are the two "pumping" chambers?
The right and left ventricles.
Blood that has just moved through the tricuspid valve will enter what chamber?
The right ventricle.
Myocardial Infarction
What structure paces the heart at 40 bpm?
AV node (atrioventricular node)
What type of blood vessel is the thinnest, only one layer of cells?
capillaries
What are the two AV valves?
The tricuspid and the bicuspid valves.
Blood that is traveling through the pulmonary arteries is going where?
To the lungs
“bubble” on an artery due to weakness in arterial wall; can rupture and cause massive blood loss
Aneurysm
What is the last place the electrical impulse reaches (the end of the road, so to speak)
The Purkinjie fibers
What type of blood vessel carries blood away from the heart?
artery
What is the circuit that carries blood to the lungs and back?
The pulmonary circuit.
*This is the only place in the body where arteries carry deoxygenated blood and veins carry oxygenated blood.
What are the two places where gas exchange occurs in the body? (what boxes were purple on your flow chart?)
body cells and lungs
Lack of oxygen in the brain due to a hemorrhage or a clot
stroke
What anatomical structure in the heart are the right and left bundle branches embedded in?
Interventricular septum
What type of blood vessel has two extra elastic layers of tissue to account for the high pressure that it is under?
Artery
What two blood vessels bring blood back to the heart from the body?
The inferior and superior vena cava.
If blood is in an atrium, what TYPE of valve will the blood travel through next?
an AV valve (atrioventricular valve).
A blood clot that has broken off and is traveling through the blood stream.
Embolism
What does the SA node pace the heart at normally?
100bpm
If blood is pumped out of the heart, name the type of blood vessels it will flow through in order.
Artery, arteriole, capillary, venule, vein.
