What major steps are involved in gas exchange?
What two systems are involved in gas exchange in humans?
What is the difference between respiration (breathing) and cellular respiration?
What is ventilation?
At what locations does gas exchange occur in our bodies?
What are alveoli?
Describe the gas exchange that takes place in the lungs.
Explain the mechanisms by which oxygen and carbon dioxide are exchanged in the lungs.
What is the diaphragm?
Explain how we move air into and out of our lung.
What is partial pressure of a gas?
What is the partial pressure of oxygen in air?
How is partial pressure related to gas exchange in the lungs?
Explain what leads to movement of oxygen and carbon dioxide between air in the lungs and blood in capillaries.
What are asthma and emphysema?
Be able to relate why we need oxygen in the first place, how we get air into our lungs and how we get oxygen out of the air in our lungs.
What are the two circulatory systems that humans have in our bodies?
What is the function of each of the two systems?
Know where in the circulation of blood in our bodies the blood is rich in oxygen and what blood vessels are carrying blood depleted of oxygen.
What are atria and ventricles? What do they do?
What sounds does the heart make when it beats? What causes those sounds?
What is a heart murmur?
What is the cardiac cycle?
What pigmented proteins carry oxygen in the blood of animals? Which is found in humans?
Explain how the heart contracts in a coordinated manner that results in blood being pumped successfully through the heart in the intended direction.
Describe arteries, veins and capillaries.
Explain gas exchange that occurs between blood and tissues.
Describe the mechanism responsible for the exchange of gases between blood and tissues.
