Up up way we go!
The part of the nose that meets the frontal muscle
Root of the Nose
This is the part where the trachea bifurcates or divides into the left and right bronchi.
Carina
The lungs are located in this body cavity.
Thoracic cavity
This is the process by which the oxygen is exchanged with carbon dioxide.
The RBCs are produced in this organ.
Bone Marrow
This is the histology of the respiratory epithelium.
Pseudostratified epithelium with cilia
These are the parts of the respiratory system where gas exchange occurs.
Respiratory Zone
This blood vessel delivers deoxygenated blood to the lungs.
Pulmonary artery
This is the pressure in between the lungs and the body wall and should always be negative.
Intrapleural pressure
Oxygen is stored in the muscle in this form.
Myoglobin
These are air-filled spaces in the bone.
Paranasal sinuses
These cells produce surfactant.
Type II alveolar cells
These are the lobes of the right lung.
Superior, Middle and Inferior lobes
This law describes the relationship between the pressure and volume of a gas at a constant temperature.
Boyle's Law
The enzyme that combines water and carbon dioxide.
Carbonic anhydrase
This tube connects the nasopharynx to the middle ear.
Eustachachian tube
This is the term used for the structure made up of Type I alveolar cells and pulmonary capillaries.
Air-blood barrier
This is the area where the blood vessels, bronchi, and lymphatics enter the lung.
Hilum
This is the measure of the change in lung volume in response to changes in transpulmonary pressure.
Lung Compliance
These two phenomenon describes the dissociation of oxygen and carbon dioxide from the hemoglobin based on their concentration.
Bohr Effect and Haldane Effect
This is the landmark that divides the upper and lower respiratory tract.
Glottis
This is the phospholipid component of surfactants.
Dipalmitoylphosphatidylcholine/ phosphatidylcholine
These are pyramidal shape units in the lungs that function independently from each other.
Bronchopulmonary segment
The water in the alveoli causes increased airway resistance due to this phenomenon.
Surface tension
2,3 - Diphosphoglycerate is derived from this nutrient.
Glucose
