AP102 Flashcards
Where does gas exchange take place in the lungs?
The Alveoli
What is hypocapnia
Low levels of CO2
What is alveolar diffusion
Oxygen exchange between alveolar air and capillary blood at sea level
What are the 5 stages of respiration?
- Ventilation
- Diffusion (1)
- Transportation
- Diffusion (2)
- Utilization
What is the formula for the utilization stage of respiration and what is the key by-product?
Fuel + O2 = Energy + H20 + CO2
When altitude is the cause for hypoxic hypoxia, what is one of the main factors that will induce the worst symptoms?
Dehydration
What is the composition of blood?
55% Plasma, 45% red blood cells, and a small % of white blood cells and platelets
What is the metabolic process?
The body acquires energy and turns that energy into chemical energy. After it is tuned into chemical energy, it is then turned into mechanical and thermal energy.
What part of the red blood cell is responsible for carrying O2?
Hemoglobin
What are the two types of circulation in the heart?
- Pulmonary Circulation
2. Systemic Circulation
What is the purpose of respiriation?
To get O2 into the body and remove excess CO2
What is the normal breathing rate of the average adult?
12-16 breaths per minute
What is the most important factor in the control of ventilation under normal conditions?
PCO2
What is the main purpose of the red blood cells?
Carry oxygen
