the right lung as _____ lobes, while the left lung has _____ lobes
three, and two
respiration, or the transfer of gases, occurs in the ______
alveoli
the transfer of gases (O2 and CO2) occurs across how many structures
three
the alveoli is surrounded by a web or network of what
capillaries
the gases we mainly breathe in and out are:
nitrogen, carbon dioxide, and oxygen
T or F: when you breathe in the lungs are full of air and expand like a balloon. When you breathe out, the lungs empty like balloons and flatten.
False
- The lungs have a sponge like appearance and are not like expandable balloons. There is always air in your lungs.
We breathe so that we can:
- exhale carbon dioxide to lower blood acidity
- inhale oxygen
- exhale carbon dioxide
the main mechanism that allows us to breathe in is:
the contraction of the diaphragm along with the intercostal muscles
imagine blowing up a balloon with only the air that you normally breathe in or out (without taking a big breath). this volume of air is called
TV
(Tidal Volume)
Imagine inhaling all the air you can and then blowing up a balloon by forcing all the air you can out of your lungs, this volume of air exhaled is called the:
VC
(Vital Capacity)
Ve is the product of two variables. They are:
Tidal Volume and Breathing Frequency
The gold standard measure for cardiovascular fitness is:
Volume of oxygen consumed during exercise
The trachea is surrounded by _____ which offers ______.
hyaline cartilage, protection
describe how air enters our lungs?
The air pressure is greater on the outside rather than the inside of our lungs, so air rushes in
If you could change one component of Ventilation to improve performance, which would it be?
BF
Pound for pound, children breathe _____ during exercise.
more air than adults
VO2 max is higher in ____ as compared with ____, and appears to ____ .
males, females, increase in youth and then decrease afterward
Of the four variables of cardiac output and ventilation, which factor increases the least from rest to max?
SV
SV at rest
70 ml
SV at max
180 ml
