Circulatory System
This vessel carries blood AWAY from the heart
What is an artery?
This side of the heart pumps blood to the lungs.
What is the right side?
This process brings air to the lungs.
What is inhalation?
This structure warms and moistens incoming air.
What is the nasal Cavity?
This is the procsess of breaking down food into usable molecules.
What is digestion?
These vessels allow exchange between blood and body cells
What are capillaries?
These valves prevent blood from flowing backwards.
What are heart valves?
This type of respiration requires oxygen.
What is aerobic respiration?
This flap prevents food from entering the airway.
What is the epiglottis?
This type of digestion uses enzymes and acids.
What type of blood cell carries oxygen?
What are red blood cells?
This chamber pumps oxygenated blood to the body.
What is the left ventricle.
This is the main gas exchanged into the blood in the lungs.
What is Oxygen?
This tube carries air to the lungs and is supported by cartilage.
What is the trachea?
This organ produces bile.
What is the liver?
This is the normal blood pressure reading for a healthy person.
What is 120/80?
This sound represents ventricular contraction.
What is "lub"?
This structure is only one cell thick and allows rapid diffusion of gases between air and blood.
What are alveoli?
This happens to air pressure in the lungs during inhalation.
What is it decreases?
This movement pushes food through the esophagus.
What is peristalsis?
This is the path blood takes after leaving the left ventricle.
What is aorta-> body-> vena cava-> right atrium?
This structure carries oxygenated blood from the lungs to the heart.
What are pulmonary veins?
This waste product causes muscle fatigue during intense exercise.
What is lactic acid?
This explains why cappillaries surround alveoli.
What is to allow for rapid diffusion of oxygen and carbon dioxide?
This explains why the small intestine is long and folded.
What is to increase surface area for absorption?
