1B Define: Arteries
Blood vessels that carry blood away from the heart
1C Define: Capillaries
Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells and are located between arteries and veins
2
What purpose do the lungs serve?
Oxygenate the blood and allow the blood to get rid of carbon dioxide.
3
What purpose does the heart serve?
Pumps blood throughout the circulatory system.
4
How many chambers are in a human heart? Name them.
Four chambers: right atrium, left atrium, right ventricle, left ventricle
5
What is special about a four-chambered heart as compared to a three-chambered heart or a two-chambered heart?
A four-chambered heart is much more efficient than other kinds of hearts.
6 In what kind of blood vessels does the blood transfer oxygen to the cells and pick up wastes?
Capillaries
7 When deoxygenated blood is returning to the heart, into what chamber does it enter the heart?
Right atrium
8
After entering the heart, the deoxygenated blood is then transferred to a second chamber. What chamber is that?
Right ventricle
9
When the deoxygenated blood leaves the heart, where does it go?
Lungs
10
When the oxygenated blood comes back to the heart, what chamber does it fill?
Left atrium
11
Once the oxygenated blood is back in the heart, it is then transferred to another chamber. What chamber is that?
Left ventricle
When oxygenated blood leaves the heart, through what artery does it travel first?
Aorta
13 Most veins carry what kind of blood (oxygenated or deoxygenated)? Are there any exceptions to this general rule?
Deoxygenated blood
There are exceptions
14 Name the three types of blood cells and their main job in the blood.
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.
15
What makes up more than half your blood?
Plasma
16 What is hemoglobin and where is it found?
Hemoglobin is a protein that carries oxygen. It is found in red blood cells
17
Where are red blood cells produced?
Bone marrow
18
What are alveoli? What happens in the alveoli?
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.
19
What kind of blood vessels surround the alveoli?
Capillaries
20
Where are the bronchial tubes found, and what travels in them?
Lungs
Air
21
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.
Nasal cavity, pharynx, larynx, trachea, bronchial tubes, alveoli
22
Which parts listed in the problem above contains the vocal chords?
Larynx
23
What controls the volume of sound produced by the vocal chords? What controls the pitch of the sound produced?
The amount of air that passes over the vocal chords controls the volume if the sound, and the tightness of the vocal chords determines the pitch
24
A sample of fluid was taken from a tube within a plant. If it is mostly water, which was it taken from: a xylem or phloem tube?
Xylem
1A Define: Veins
Blood vessels that carry blood back to the heart
