In the lungs what happens to CO2?
CO2 is exchanged for O2

What is a heart murmur?
A heart murmur is an extra or unusual sound heard during a heartbeat. Murmurs range from very faint to very loud. Sometimes they sound like a whooshing or swishing noise.

What are the three types of blood vessels?
1. Arteries
2. Veins
3. Capillaries

How long does it take for red blood cells to leave the heart (Aorta) and come back to right pulmonary arteries?
It takes about 20 seconds for red blood cells to circle the whole human body.
After blood is pumped from the right ventricle what does it have to pass through to get to the lungs?
It is pumped out of the heart through the pulmonary arteries to the lungs.
300
What is Arteriosclerosis?
A buildup of plaque leading to the hardening of the arteries and the loss of their elastic properties.
300
What is the smallest blood vessel?
The Capillary
(So small that ten capillaries bundled together would have the diameter of a single human hair)
300
How many red blood cells are in tiny droplet of blood?
Within a tiny droplet of blood, there are some 5 million red blood cells
400
The atria and the ventricles are separated from each other by the thick muscular wall called the?
Septum
400
What is the function of the pulmonary pathway?
Transports oxygen-poor blood to the lungs.
400
What is a Valve Defect?
A heart murmur due to blood flowing in the wrong direction.
400
What do the veins do?
Carry oxygen-rich blood away from the heart.
400
If you were to lay out all of the arteries, capillaries and veins in one adult, end-to-end, they would stretch about 60,000 miles. How many percentage would capillaries take up?
Capillaries takes up about 80% of the 60,000 miles.
500
What is the sinoatrial node?
Stimulates the muscle cells to contract and relax rythmically.
500
What is the function of the coronary pathway?
To provide blood to the muscle tissue of the heart itself.
500
What is a Coronary Bypass operation?
A segment of healthy artery or vein is taken from somewhere else in the body and used to create a new pathway around a blocked vessel near the heart.
500
-Carry oxygen rich blood away from the heart.
- Have highly elastic walls at the artery to expand as a wave of blood surges through it during the contraction and then snaps back again during relaxation.
After knowing these two facts what kind of blood vessel does this match to?
The Arteries
500
If your Heart was taken out of your body will it beat or not?
the heart can keep beating after it is removed from the body.
This eerie pulsing occurs because the heart generates its own electrical impulses, which cause it to beat. As long as the heart continues to receive oxygen, it will keep going, even if separated from the rest of the body.
