The Heart Part 1- Chambers and Valves
How many valves are there in the heart?
4
When is carbon dioxide produced by blood?
Kreb's cycle
What carries blood from the left ventricle to the whole body?
aorta
What is a blood vessel that carries blood away from the heart?
artery
What valves control the the blood flow from the atria into the ventricles beneath them?
artioventricular valves
Where is the aortic valve found?
at the beginning of the aorta
Where is the pulmonary valve found?
at the beginning of the pulmonary trunk
What are the receiving chambers called?
atria
What is another name for the mitral valve?
biscuspid valve
What happens when the artioventricular valves open?
blood flows from the atria to the ventricles
What happens when the semilunar valves are open?
blood flows from the ventricles to those 2 arteries
What happens when the semilunar valves are closed?
blood is prevented from passing back in to the ventricles from those 2 arteries
What happens when the artioventricular valves close?
blood is prevented from passing back to the atria
What does deoxygenated blood have a lot of?
carbon dioxide
What is a way that cells emote oxygen from the blood?
electron transport
What carries blood from the lower body except from the lungs?
inferior vena cava
What are the 2 atria separated by?
interatial wall
What are the 2 ventricles separated by?
interventricular wall
Why is the wall of the right ventricle thick?
it must pump blood to the lungs and back to the heart
Why is the wall of the left ventricle the thickest wall?
it must pump to the entire body and back
Which chambers of the heart contain oxygenated blood?
left
Which valve is found between the left atrium and ventricle?
mitral valve
What carries blood to the lungs from the right ventricle?
pulmonary trunk
What are the 2 semilunar valves?
pulmonary valve and the aortic valve
What carries blood to the left atrium from the lungs?
pulmonary veins
Which chambers of the heart contains deoxygenated blood?
right
What valves have control of the blood flow form the ventricles to the pulmonary trunk and aorta?
semilunar valves
What are the 2 vessels that carry blood to the right atrium?
superior and inferior vena cava
What carries blood vessel carries blood from the head, neck, and shoulders?
superior vena cava
What are the 5 major blood vessels of the heart?
superior vena cava inferior vena cava pulmonary trunk pulmonary veins aorta
What do you know if the blood is deoxygenated?
that it already passed through the tissues and had oxygen removed from it and cargo dioxide added to it
What happens when the cardiac muscle contracts?
the volume of the chamber decreases, the pressure of the blood within the camber increases, and the blood moves out of the chamber
Why are the walls of the atria not thick?
they only have to pump blood to the ventricles
What are the function of the valves?
to make sure blood flows through the heart in the correct direction
Which valve is found between the right atrium and ventricle?
tricuspid valve
What are the 2 artioventricular valves?
tricuspid valve mitral valve
What is a blood vessel that carries blood back to the heart?
vein
What are the pumping chambers called?
ventricle
