What type of cell transports oxygen?
red blood cell
What is the first body structure that air goes through?
nostrils
What is the cellular respiration chemical reaction?
oxygen + glucose ---> ATP + water + carbon dioxide
What allows the oxygen to diffuse through the capillaries?
Thin membranes
What is the name of the oxygen binding protein?
Hemoglobin
What is the last body structure that air goes through?
alveoli in lungs
Where does cellular respiration occur?
Mitochondria
What are the 4 characteristics of an efficient gas exchange system?
Thin, moist, large concentration gradient and SA:V
What allows cells to stay alive?
oxygen
When the air meets the bronchi, where does it go next?
bronchioles
The respiratory system exchanges what two gases?
Oxygen and carbon dioxide
What is not required to move oxygen or carbon dioxide across membranes?
Energy
How much oxygen is taken up by red blood cells?
98%
The air moves through how many structures until it gets to the alveoli?
7
What are the waste products of respiration?
Water and carbon dioxide
Oxygen moves from the alveoli to what?
blood in the capillaries
Where does the oxygen that's not taken up by red blood cells go?
It remains dissolved in body tissues (lungs)
What happens in the alveoli, the final body structure that air moves through?
gas exchange between oxygen & carbon dioxide
What is the primary function of cellular respiration
To produce energy (ATP) for survival
What ensures large volume of oxygen diffusion in lungs?
Many alveoli (SA:V) and a large concentration gradient of oxygen in lungs.
