Definitions
Define arteries.
1b.
Arteries are blood vessels that carry blood away from the heart.
What purpose does the heart serve?
3.
The heart pumps blood throughout the circulatory system.
What kind of blood vessels surround the alveoli?
19.
Capillaries surround the alveoli, since that is where the blood gets oxygen and release wastes.
Where are blood cells produced?
17.
Blood cells are produced in bone marrow.
In what kind of blood vessels does the blood transfer oxygen to the cells and pick up wastes?
6.
Capillaries are vessels that allow exchange of gases between the cells and the blood.
Define veins.
1b.
Veins are blood vessels that carry blood back to the heart.
When deoxygenated blood leaves the heart, where does it go?
9.
When deoxygenated blood leaves the heart, it heads for the lungs to become oxygenated.
What are alveoli? What happens in the alveoli?
18.
Alveoli are small sacs at the end of tiny bronchial tubes. Oxygenation of blood takes place in them. The blood also gives up waste products there.

What makes up more than half of your blood?
15.
More than half of your blood is blood plasma.
When oxygenated blood comes into the heart, what chamber does it fill?
10.
Oxygenated blood that is returning to the heart fills the left atrium.
Define Capillaries
1c.
Capillaries are tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells and are located between the arteries and veins.
How many chambers are in a human heart? Name them.
4.
The human heart has four chambers: the right atrium, left atrium, right ventricle, and left ventricle.
When you inhale, air travels through the following parts of the respiratory system:
pharynx, nasal cavity, trachea, larynx, alveoli, bronchial tubes.
List these parts in the order in which inhaled air passes through them.
21.
Nasal cavity, pharynx, larynx, trachea, bronchial tubes, alveoli
What is hemoglobin, and where is it found?
16.
Hemoglobin is a protein that carries oxygen. It is found in the red blood cells.
When deoxygenated blood is returning to the heart, into what chamber does it enter the heart?
7.
Deoxygenated blood comes into the heart through the vena cava and gets dumped into the right atrium.
What purpose do the lungs serve?
2.
The lungs oxygenate the blood and allow the blood to get rid of carbon dioxide.
After entering the heart, the deoxygenated blood is then transferred to a second chamber. What chamber is this?
8.
After filling the right atrium, the deoxygenated blood is pushed into the right ventricle.
Where are the bronchial tubes found, and what travels in them?
20.
Bronchial tubes are found in the lungs. Air travels through them.
Name the three types of blood cells and their main job in the blood.
14.
The red blood cells carry oxygen to the other cells of the body. The white blood cells fight disease-causing organisms, and the blood platelets aid the blood clotting process.
When oxygenated blood leaves the heart, through what artery does it travel first?
12.
When oxygenated blood is leaving the heart, it is pumped out into the aorta.
Which of the following parts contains the vocal cords?
pharynx, nasal cavity, trachea, larynx, alveoli, bronchial tubes
22.
Vocal cords are found in the larynx.
What is special about a four-chambered heart as compared to a three-chambered heart or a two-chambered heart?
5.
A four-chambered heart is much more efficient than other kinds of hearts.
What controls the volume of the sound produced by the vocal cords? What controls the pitch of the sound produced?
23.
The amount of air that passes over the vocal cords controls the volume of the sound, and the tightness of the vocal cords determines the pitch.
Most veins carry what kind of blood (oxygenated or deoxygenated)? Are there any exceptions to this general rule?
13.
Veins usually carry deoxygenated blood, because they are carrying it back to the heart to be pumped into the lungs. There are exceptions: The pulmonary vein, for example, carries oxygenated blood to the heart from the lungs.
Once the oxygenated blood comes into the heart, it is then transferred to another chamber. What chamber is that?
11.
After entering the left atrium, the oxygenated blood is dumped into the left ventricle.
