Where does oxygen poor blood travel to after leaving the heart
lungs
100
Capillaries are very wide, true or false.
False

What is the name of the liquid that red blood cells float in?
Plasma
100
List at least 4 structures of the respiratory system.
1. Nasal cavity
2. Trachea
3. pharynx
4. larynx
5. Bronchi
6. Alveoli
7. Lungs
100
What are the four chambers of the heart?
A. right atrium
B. right ventricle
C. left atrium
D. left ventricle
200
What is the purpose of valves? Where are valves found?
Valves prevent the back-flow of blood
in the heart
200
Describe the function of the respiratory system.
The system responsible for the exchange of gases between the external environment and the blood.
200
Describe the function of white blood cells.
To fight off foreign invaders and pathogens.
200
Describe exhalation. Using the words
1. Diaphragm
2. lung capacity
3. relax
The diaphragm relaxes (moves up) and inter-coastal muscles relax (come in), lung capacity decreases and air moves out of the lungs.
200
What are the two veins that dump blood into the right atrium?
Superior and inferior Vena Cava
300
Describe the function of red blood cells.
Red Blood Cells - carry oxygen around the body.
300
Describe inhalation. Use the words
1. contracts
2. lung capacity
3. diaphragm
The diaphragm contracts (moves down) and inter-coastal muscles relax (go out), lung capacity increases and air moves into the lungs.
300
What percent of your blood is white blood cells when you are healthy?
<1%
300
What are alveoli and what is their function?
Alveoli are tiny sacs at the end of the bronchioles where gas exchange occurs. It allows oxygen and carbon dioxide to move between the lungs and the bloodstream.
300
Describe the function of platelets
Platelets - responsible for forming blood clots to stop your body from bleeding out.
400
Describe 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
List 2 differences between veins and capillaries.
1. Veins carry deoxygenated blood
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 (windpipe)
400
How do the heart and lungs work together to maintain (homeostasis) a self regulating process by which a living organism can maintain internal stability, well adjusting to external changing conditions.
move oxygen and nutrients throughout body, removes wastes such as carbon dioxide
Heart- pumps blood, carries O2 and Co2
Respiratory System - exchanges needed gases for waste in lungs,
500
List the function of the arteries.
Carry oxygenated blood away from the heart.
500
What are the names of # 2, 3, and 9?
#2 pharynx, #3 larynx, # 9 diaphragm
500
List 3 functions of the Circulatory System.
1. Deliver oxygen and nutrients around the body.
2. Removes wastes from cells.
3. Fight disease and pathogens.
4. Regulate body temperature.
5. Transport hormones around the body.
500
Label all nine parts correctly!
1. nasal cavity, 2 pharynx, 3. larynx
4. trachea, 5. bronchi, 6. lungs, 7. bronchioles
8. alveoli 9. diaphragm
500
What are the names of E, F, and G?
E= vein (superior vena cava)
F = aorta G= pulmonary artery pulmonary
