Q

What chamber of the heart receives blood returning from the body

Study These Flashcards
A

The Right Atrium

25
What transports blood with carbon dioxide from the body to the heart.
The Superior and Inferior Vena Cava
26
Phagocytes and lymphocytes are both types of
White blood cells
27
What transports blood with oxygen from the heart to the body.
The Aorta
28
Proteins that have a specific fit to a specific antigen are called
Antibodies
29
The purpose of heart valves is to
Prevent the backflow of blood
30
What part of the blood are cellular fragments
Platelets
31
What do platelets do?
They help your blood clots and stop the bleeding
32
What does the red coloring of blood come from?
Hemoglobin
33
What does the protein Hemoglobin contain?
Iron
34
What do the red blood cells deliver to cells and tissues?
Oxygen
35
What do veins do?
They take blood to the heart
36
What is the smallest type of blood vessel in the body?
The capillaries
37
What are the 3 main types of blood vessels in the body
Arteries, Capillaries and Veins
38
What does the left side of the heart do?
It pumps oxygenated blood
39
What does the right side of the heart do?
It pumps de-oxygenated blood
40
Are the atria found at the top or bottom of the heart.
Top
41
Are the ventricles found at the top or bottom of the heart
Bottom
42
If you are looking at a diagram of the heart where would the right side of the heart be from your point of view
On the left side
43
Which chambers have thicker walls, the atria or the ventricles
The ventricles
44
What does the word 'Pulmonary' likely involve
The Lungs
45
What is the pathway of oxygenated blood
Lungs -> Pulmonary vein -> Left atrium -> Mitral/Bicuspid valve -> Left Ventricle -> Aortic Valve -> Aorta
46
What is the Aorta?
The Aorta is a major artery that sends out oxygenated blood throughout the body.
47
How does the heart get its own blood?
Through the Coronary Arteries
48
What do the coronary arteries branch off of?
The Aorta
49
What do the coronary arteries eventually deliver blood to?
The Capillaries
50
What do the capillaries that the coronary arteries deliver blood to give to the heart
Oxygen and Glucose
51
What do the coronary veins do?
They take the de-oxygenated blood to the right atrium, so the blood can become oxygenated again.
52
About how many times does the human heart beat per day?
Over 100,000 times
53
What do Phagocytes do
They eat the foreign bodies that enter your body, so the body has a less likely chance to be infected or for you to get sick
54
What do Lymphocytes do
They create Anti-bodies to destroy the harmful bacteria.
