Test- Circulatory Flashcards
- What happens after old blood, which has already circulated through the body, moves into the heart?
The old blood travels to the lungs for more oxygen.
Pg. 68
- How long does it take for your heart to pump blood through your entire body?
About a minute
Pg. 68
- What role does your brain play in the circulation of blood through your body?
It signals the heart to beat.
Pg. 68
- When blood flows into the right atrium from the body, it contains
Little oxygen and a lot of carbon dioxide
Pg. 73
- The fusion of the atria is to
Relieve blood that comes into the the heart.
Pg. 73
- When blood flows into the left atrium from the body, it contains
A lot of oxygen and little carbon dioxide.
Pg. 73
- Place the following events in sequence A) the atria begins to fill with blood; b) the valve between the ventricles and the atria close; c) blood is pushed through our heart.
A, b, c
Pg. 73
- Through which type of circulation does blood flow to your hands and feet?
Systemic
Pg. 76
- Which chamber of the heart pumps oxygen-poor blood to the lungs?
Right ventricle
Pg. 73
- How does pulmanary circulation differ from systemic circulation?
Systemic circulation occurs throughout the body; pulmanary circulation occurs in the heart and lungs.
Pg. 73
- Through which type of circulation does blood flow to from your heart to your lungs and back?
Pulmanory
Pg. 76
- What is the main difference betweeen your ventricles and your atria?
Your atria brings blood into your heart; your ventricles pump it out.
Pg. 73
- Wichita if these heart structures prevents blood from flowing backwards?
Valve
Pg. 73
- What causes blood pressure?
The force at which the ventricles contact
Pg. 73
- True or false; the left ventricle pumps blood to the lungs?
F, right
Pg. 73
- True or false; the two lower chambers of the heart are called atria?
F. Ventricles
Pg. 73
- True or false; blood flows from the heart to the body through veins?
F, arteries
Pg. 73
- Blood returns to th heart from the body through the big blood vessels called…..
Vena cava
Pg. 73
- The circulatory system carries the needed materials oxygen and…… to the body cells?
Glucose, nutrients.
Pg. 76
- Substances are exchanged between the blood and body cells in the blood vessels known as…
Capillaries
Pg. 73
- What is the structure that is on the left side above the left ventricle? What structure leads into this? What is the level of oxygen content?
The left atrium, Pulmanory veins, high in oxygen
Pg. 73
- What is the name of where blood flows after the superior vena cava? Where does the blood flow through next after this?
Right atrium, after that blood flows into F, the right ventricle.
Pg. 73
- What is the structure that is right next to the left atrium and the left ventricle and what is its function?
The valve that separates the left atrium from the left ventricle. It function is to prevent blood from flowing backwards.
Pg. 73
- What is the structure where blood flows goes after going to the left atrium? Is the blood high or low in oxygen explain.
It is the left ventricle. Blood entering the left ventricle is high in oxygen, because it has just come from the left atrium which receives oxygen- rich blood from the lungs.
Pg. 73
What is in between the left and right ventricle? What would happen if a person had a hole in it?
It is the septum. A hole in the septum would allows oxygenated and deoxygenated blood to mix. As a result less oxygen would go to your body cells.
