What is the lungs?
100
These blood vessels always carry blood AWAY from the heart.
What are arteries?
100
This is the liquid portion of the blood.
What is plasma?
100
The trachea is surrounded by this substance, in order to give it structure and support.
What is cartilage?
100
This is a disease that is characterized by high blood pressure.
What is hypertension?
200
This is the largest artery in the body.
What is the aorta?
200
These blood vessels always have valves.
What are veins?
200
This blood component is responsible for initiating blood clots.
What are platelets?
200
This is the structure that is surrounded by capillaries and is the site of gas exchange.
What are the alveoli?
200
This disease is an allergic reaction that causes the bronchioles in the lungs to swell.
What is asthma?
300
The left side of the heart always carries blood that is high in _________________.
What is oxygen?
300
These vessels are one cell thick and are found surrounding each individual alveolus in the lungs.
What are capillaries?
300
This is the main job of white blood cells.
What is to fight infection? (or pathogens, bacteria, disease, etc)
300
This structure causes changes in pressure in the lungs, which expands our chest cavity to enable us to breathe.
What is the diaphragm?
300
This disease is characterized by a build-up of plaque in blood vessel walls.
What is atherosclerosis?
400
This blood vessel carries blood from the heart to the lungs.
What is the pulmonary artery?
400
This is the only artery that carries de-oxygenated blood.
What is the pulmonary artery?
400
Red blood cells carry oxygen on this important blood protein.
What is hemoglobin?
400
The nasal cavity and trachea is lined with these structures, in order to trap dust and bacteria.
What is cilia?
400
This is when the lung tissue (specifically alveoli) lose elasticity, causing decreased surface area for absorption of oxygen.
What is emphysema?
500
This blood vessel carries oxygenated blood back to the heart.
What is the pulmonary vein?
500
This is the only vein that carries oxygenated blood.
What is the pulmonary vein?
500
This is where red blood cells are made.
What is the bone marrow?
500
This is the process that enables oxygen to enter the bloodstream in the lungs, and enables carbon dioxide to leave.
What is diffusion?
500
This is the reason why the lungs branch out into so many tiny air sacs called alveoli.
