Where does blood carrying carbon dioxide travel to after leaving the heart?
Lungs
100
True or False. Capillaries are very wide.
False. They are very thin. The size of one blood cell.
100
What ventricle does the blood leave to enter the lungs?
Right ventricle.
100

1. Nasal cavity
2. Trachea
3. Bronchi
4. Alveoli

What are the four chambers of the heart?
A. right atrium
B. right ventricle
C. left atrium
D. left ventricle
200
What are valves?
Valves prevent the back-flow of blood in the circulatory system.
Valves are found in the heart and veins, but not the arteries.
200
Describe the function of the respiratory system.
The respiratory system is responsible for importing oxygen into the lungs and exporting carbon dioxide from the body.
200
How are nutrients transported in the body?
Nutrients are transported by the blood.
200
Describe exhalation.
The diaphragm relaxes (moves up) and the muscles relax (come in), lung capacity decreases and air moves out of the lungs.
200
How are the Heart and Lungs connected?
The lungs import/ export oxygen/ carbon dioxide into the body while the heart transports these substances to and away from the muscles.
300
What is the main function of red blood cells?
To transport oxygen to the muscles and carbon dioxide out of the body.
300
Describe inhalation.
The diaphragm contracts (moves down) and the muscles relax (go out), lung capacity increases and air moves into the lungs.
300
Name three parts of the Circulatory System and their function.
Blood, blood vessels, heart
Blood - fluid that transports materials.
Blood vessels - Passageways from the heart to the muscles and organs.
Heart - pumps blood throughout the body.
300
What are Alveoli and why are they important?
Alveoli are tiny sacs at the end of the bronchioles where gas exchange occurs. They allow oxygen and carbon dioxide to move between the lungs and the bloodstream.
300
True or False. The circulatory system and the respiratory system work together.
True
400
What is the function of the heart?
It is responsible for pumping blood around the body, supplying oxygen and nutrients and removing carbon dioxide and waste.
400
What are the names of # 1, 5 and 8
#1 Nasal cavity (nose)
# 5 Bronchi #8 Alveoli
400
What are two differences between veins and capillaries?
1. Veins carry carbon dioxide.
2. Capillaries facilitate gas exchange.
3. Veins have valves - capillaries do not.
4. Capillaries are one cell thick.
400
What is the name of #4?
Trachea
400
True or False. In drawings and diagrams veins are always blue and arteries are always red.
True.
500
What is one function of the arteries?
The arteries are passageways that connect the heart to the muscles. They allow the transport of oxygen and nutrients to the muscles and organs.
500
What is the name of number 9?
# 9 diaphragm
500
What is one function of the Circulatory System?
1. Deliver oxygen and nutrients around the body.
2. Removes waste and carbon dioxide from the cells.
500

8. alveoli 9. diaphragm
500
What are two differences between veins and arteries?
Arteries transport oxygen.
Veins transport carbon dioxide.
Veins have valves.
