Test- Circulatory Flashcards
4.
How long does it take for your heart to pump blood through your entire body?
WKST
A minute
5.
When ventricles contract, blood is pumped out of what?
CLF
your heart
6.
What role does your brain play in the circulation of blood through your body?
WKST
It signals the heart to beat
13.
When blood flows into the right atrium from the body, it contains
WKST
little oxygen, lots of carbon dioxide
15.
When blood flows into the left atrium from the body, it contains
WKST
lots of oxygen, little carbon dioxide
21.
How does pulmonary circulation differ from systemic circulation?
Systemic circulation occurs throughout the body; pulmonary circulation occurs in the heart and lungs.
22.
What type of tissue on the heart pumps blood throughout the body?
muscle tissue
23.
Where in your body can you find the most blood vessels
virtually everywhere
26.
Through which type of circulation does blood flow to from your heart to your lungs and back
Pulmonary
30.
What is the main function of platelets
Helping your blood clot
36.
What causes blood pressure
The force with which the ventricles contract
38
T or F?
The cardiovascular system consists of the heart, blood vessels and LYMPH
false, blood
40.
T or F
The two lower chambers of the heart are called ATRIA
false, ventricles
- T or F
As blood moves away from the heart, blood pressure INCREASES
false, decreases
- complete the statement
Fibrin is produced when the blood components called ____________ start a chain reaction that produces a blood clot
Platelets
46.
Blood that contains large amounts of carbon dioxide flows from the body into the _______ atrium of the heart.
Right
47.
Blood returns to the heart from the body through the big blood vessels called _________
Vena Cava
48
Blood that is rich in oxygen leaves the heart through the blood vessel known as the
Aorta
55.
Substances are exchanges between the blood and body cells in the blood vessels known as
Capillaries
- What’s the function of the pulmonary arteries and veins
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs
CLF
59.
What’s the pathway of blood
Superior vena cava, inferior vena cava, right atrium, right ventricle, pulmonary trunk, right pulmonary artery, LUNGS, right pulmonary veins, left pulmonary vein, left atrium, left ventricle, aorta
60.
What are the blood vessels called that go into the left atrium
Pulmonary veins
CLF
61
Where does the aortic arch’s blood lead
Carries heart from body
CLF
63.
What’s the function of a valve
Separates left atrium
CLF
64
When blood enters the left ventricle, is the blood low in oxygen of high
High
CLF
65.
What would happen if you had a hole in your septum
Poor blood would mix with oxygen that is rich with blood
CLF
