Bony ridges on the lateral walls of the nasal cavity that increase the turbulence of air flow (which helps to trap pathogens)
paranasal sinuses
nasal septa
conchae
nostrils
1. larynx
2. nasal cavity
3. pharynx
4. trachea
Which of the following is the correct order that air would flow during inhalation.
1. alveoli
2. bronchi
3. bronchioles
Which of the following is the correct order in which air would flow after inhalation?
The majority of actual gas exchange occurs in the:
bronchi
bronchioles
alveoli
ventricles
Surfactant...
decreases the surface tension of fluid in the alveoli, which increases the elastic properties of the lungs
increases the energy required to keep the lungs inflated properly
increases the tendency of lungs to collapse
traps foreign particles and pathogens that enter the lungs
We need to eat and breathe because the release of energy in cells (for repair, mitosis and maintenance) requires...
oxygen and urea
Which organelle uses oxygen to release energy from food?
nucleus
ribosome
mitochondria
endoplasmic reticulum
When the diaphragm contracts during inspiration, the volume of the thoracic cavity increases and...
the pressure decreases, causing air to rush into the lungs.
the pressure increases causing air to rush out of the lungs.
When the diaphragm relaxes during expiration, the volume of the thoracic cavity decreases
... and the pressure also decreases, causing air to rush into the lungs.
...and the pressure increases, causing air to rush out of the lungs.
According to Boyle's Law, volume and pressure are
proportionately related: when volume increases, pressure increases
inversely related: when volume increases, pressure decreases
not related; Ideal Gas Laws do not apply inside the human body
Boyle's Law does not involve pressure
