Respiratory System
The respiratory system is iportant because oxygen is necessary to make energy for your body. T/F
True
What are 3 major structures of the circulatory system?
Heart, blood vessels, and blood.
The epiglottis is a flap in the back of your throat that helps prevent food and water going down your trachea when you breathe. T/F
True
AB+ can give to anyone (universal donor) and O- can receive from anyone (universal recipent). T/F
False.
What is homeostasis?
The ability to maintain internal conditions despite what is going on outside.
Define trachea.
The windpipe.
What is the function of the circulatory system?
To move nutrients (like oxygen) and waste around the body.
What is an illness of the respiratory system where the lungs are too still to inflate?
Emphysema
What is the job of red and white blood cells?
Red blood cells carry oxygen and white blood cells fight off germs.
What is the name of Miss Gray's dog?
Buttercup.
What is the function of the respiratory system?
Gas exchange; Oxygen in and carbon dioxide out
How are arteries and veins different?
Arteries carry blood away from the heart and veins carry blood to the heart.
Draw a picture with the tracheam, bronchi, bronchioles, and alveoli labeled.

How are the ventricle and atrium different?
The atrium holds the blood and the ventricle pumps it.
Your test is on Tuesday, 11/19. T/F
True.
What are little balloon like sacs that are 1 cell thick and are the spot where gas exchange takes place in the lungs?
Alveoli.
What determines whether you can receive blood from someone?
If they have a protein in their blood you don't have you can't receive from them because your body will think it is a germ and attack it.

Describe 1 disease of the circulatory system.
Heart attack- clot in the heart
Stroke- clot in the brain
Hemophilia- blood doesn't clot
Sickle cell disease- blood cells crescent shape so clot too easily and don't carry oxygen well.
Alveoli are thin to allow oxygen to enter easily.
Alveoli are elastic to allow them to expand easily when you inhale.
Ribs having cartilage so they can expand as the luns expand.
How does the respiratory system maintain homeostasis?
Maintaing carbon dioxide levels so blood doesn't get too acidic.
Maintaining oxygen levels so energy levels are maintained.
How does the circulatory system maintain homeostasis?
Maintaining oxygen and nutrient (blood moves these around).
Maintaining temperature (too hot blood vessels expand and too cold and they contract).

How does blood flow through the heart (start with deoxygenated blood)
Right atrium, right ventricle, lungs, left atrium, left ventricle, body, and the cycle repeats.
Give an example of the circulatory system's structures relating to its function.
Capillaries being thin so oxygen and nutrients can leave them easily.
