Parts of the Heart
The four sections of the heart are called the four _________.
Chambers
Arteries, veins, capillaries
What acts like doors to let blood pass through other chambers?
Valves
Blood enters the heart here after it leaves the body.
The right atrium
Blood leaving the right atrium has low/high oxygen
low
This chamber receives oxygen-poor blood from the body.
Right Atrium
What is the general job of blood vessels?
To carry blood throughout the body?
Name one valve of the heart (you can just say the first letter + valve)
T valve, P valve, M valve, A valve.
Blood leaves the heart to go to the body through this large artery.
Aorta
Blood travelling through the ____ atrium has high oxygen levels in it.
This chamber pumps blood to the lungs.
Right Ventricle
_______ carry blood towards the heart. _______ carry blood away from the heart.
Veins, arteries
This valve connects the right atrium and right ventricle.
The T-valve
Blood travels from the right ventricle to this place for oxygen.
the lungs
Which side of the heart has high CO2 levels? How do we eliminate waste and what system does this relate to?
Which part of the heart receives oxygen rich blood, and where is it coming from?
The left atrium, the lungs
What are the thickest blood vessels in the circulatory system, and why are they the thickest?
Arteries, because they have to withstand more pressure from the heart
This valve opens to let blood flow from the right ventricle to the pulmonary artery.
The p valve (pulmonary)
In order, how does blood flow through the heart? (put the 4 chambers in order)
Right atrium, right ventricle, left atrium, left ventricle
Name the 4 components of blood and their roles
Red blood cells - carry oxygen, waste and nutrients
white blood cells - fight off infection
platelets - work to cause clotting to prevent further injury
plasma - liquid that the other components sit in
The (left/right) ventricle pumps oxygen (rich/poor) blood to the _____, where blood is then sent to other parts of the body.
left, rich, aorta
Explain what arteries, veins and capillaries do.
Arteries - carry blood away from the heart
Veins - carry blood towards the heart
Capillaries - Assists in the exchange of substances between the blood and tissues
When does the mitral valve open?
When blood is flowing from the left atrium to the left ventricle
Describe the complete path that blood takes throughout the body (6 steps)
1. right atrium, right ventricle, lungs, left atrium, left ventricle, body
Blood on the _____ side of the heart has low oxygen. Blood on the ____ side of the heart has high oxygen. Blood gets oxygen from the ________. This gas exchange happens in the ________.
right, left, lungs, alveoli
