What is the large muscle that stretches across the floor of the thoracic cavity?
Diaphragm

Why is it important to know your blood type?
In case you ever need a blood transfusion.
100
What percentage of air is made up of oxygen?
20%
100
What is considered to be "normal" blood pressure?
120/80
200
What is the main artery in the heart called?
Aorta
200
What are the two large organs located on either side of your heart?
Lungs
200
What is blood type determined by?
the protein (antigen) in your red blood cells, which is determined by heredity
200
How is the respiratory system used, other than in respiration?
Hiccuping, laughing, coughing, yawning, speaking, sighing, crying
200
What color is blood and why is it that color?
Blood is always red. The red blood cells give it this color. Oxygen-rich blood is a brighter shade of red and oxygen-poor blood is a deeper, darker color.
300
Which blood vessels are found in the alveoli?
Capillaries
300
What is the tube with rings of cartilage, extending from the larynx to the bronchial tubes?
Trachea
300
What are the differences between systolic and diastolic blood pressure?
Systolic (top number) measures the pressure in the arteries when the heart contracts. Diastolic (bottom number) measures the pressure in the arteries when the heart relaxes and receives blood from the veins.
300
What are at least three ways that smoking affects the respiratory system?
Damages the cells in your lungs, makes it difficult for you lungs to distribute oxygen, tar turns your lungs black
300
Why is it important to exhale carbon dioxide?
It will damage cells.
400
In what order does the blood flow through the heart?
Right atrium, Right Ventricle, Left atrium, Left ventricle
400
What are the tiny air sacs that are located at the end of the bronchial tubes?
Alveoli
400
What are the functions of the four components of blood?
Plasma: Transports blood cells throughout your body along with nutrients, waste products, antibodies, clotting proteins, chemical messengers such as hormones, and proteins that help maintain the body's fluid balance Red Blood Cells: Pick up oxygen in the lungs and transport it throughout the body White Blood Cells: Help your body fight off infection Platelets: Help form blood clots when a blood vessel is injured
400
How do the lungs and diaphragm work together?
When you inhale, the diaphragm contracts and lowers the air pressure in the chest cavity and fulls lungs with air. When you exhale, the diaphragm relaxes and the air pressure in the chest cavity increases and air flows out of the lungs.
400
Give at least one example of water loss through the respiratory system.
When it's cold outside, you can see your breath in the air.
500
What are the three types of blood vessels?
Arteries Veins Capillaries
500
What are the two main branches of the trachea that go into the lungs?
Bronchi/Bronchial Tubes
500
What are the functions of the three types of blood vessels?
Arteries: Blood vessels with strong walls that carry blood away from the heart Veins: Blood vessels that carry blood back to the heart Capillaries: Blood vessels used to exchange materials between blood and tissues
500
How are the circulatory system and the respiratory system related?
The respiratory system brings oxygen into the body and the circulatory system transports it throughout the body.
500
When you speak, what allows your vocal cords to produce sound?
The vocal cords become tight, squeeze together, and force air from the lungs to move between them. The air causes the vocal cords to vibrate and produce sound.
