100

This vessel carries blood AWAY from the heart 

What is an artery?

100

This side of the heart pumps blood to the lungs. 

What is the right side?

100

This process brings air to the lungs. 

What is inhalation?

100

This structure warms and moistens incoming air.

What is the nasal Cavity?

100

This is the procsess of breaking down food into usable molecules.

What is digestion?

200

These vessels allow exchange between blood and body cells 

What are capillaries?

200

These valves prevent blood from flowing backwards. 

What are heart valves?

200

This type of respiration requires oxygen. 

What is aerobic respiration?

200

This flap prevents food from entering the airway.

What is the epiglottis?

200

This type of digestion uses enzymes and acids.

What is chemical digestion?
300

What type of blood cell carries oxygen?

What are red blood cells?

300

This chamber pumps oxygenated blood to the body.

What is the left ventricle. 

300

This is the main gas exchanged into the blood in the lungs. 

What is Oxygen?

300

This tube carries air to the lungs and is supported by cartilage. 

What is the trachea?

300

This organ produces bile. 

What is the liver?

400

This is the normal blood pressure reading for a healthy person. 

What is 120/80?

400

This sound represents ventricular contraction.

What is "lub"?

400

This structure is only one cell thick and allows rapid diffusion of gases between air and blood. 

What are alveoli?

400

This happens to air pressure in the lungs during inhalation.

What is it decreases?

400

This movement pushes food through the esophagus.

What is peristalsis?

500

This is the path blood takes after leaving the left ventricle. 

What is aorta-> body-> vena cava-> right atrium?

500

This structure carries oxygenated blood from the lungs to the heart. 

What are pulmonary veins?

500

This waste product causes muscle fatigue during intense exercise.

What is lactic acid?

500

This explains why cappillaries surround alveoli.

What is to allow for rapid diffusion of oxygen and carbon dioxide?

500

This explains why the small intestine is long and folded.

What is to increase surface area for absorption?
