Pulmonary Flashcards
What is inspiration?
Inspiration is the drawing of breathing in; inhaling
What is the alveolus?
The alveolus is one of the many air sacs (alveolar sac) that supplies oxygen/CO2 excretion in the bloodstream
What is the trachea
The trachea is a protective airway that supplies a hole for bolus and air to reach their destinations
What is oxygen
Oxygen is a gas in air that is required to carry out life.
What is Tidal Volume TV?
TV is the amount of air that is usually inspired/expired in a regular breath
What is Vital Capacity VC?
VC is the total amount of air you can bring in/force out
What is expiration?
Expiration is the process of exhaling; breathing out waste
What is the nasal cavity?
The nasal cavity is the area in the nose that air flows through.
What are bronchioles>?
Bronchioles are the chambers that connect the bronchi into the alveolar sacs.
What is carbon dioxide?
CO2 is the waste product of energy production in cells.
What is the Inspiratory Capacity?
IC is the max amount of air you can inhale. Its the sum of TV and IRV
What is the Residual Volume?
The RV is the ‘left’ amount of air you have in your lungs that cannot be exhaled; it maintains shape of your lungs
What is the diaphragm?
The diaphragm is the muscles that separates the upper and lower body. It also controls breathing, as it contracts and expands for you to inhale/exhale
What is the pharynx?
The pharynx is a long tube that connects the mouth to the esophagus/larynx
What are cilia?
Cilia are tiny hair-like furs that increase surface area, and filters out particles.
What are cartilage rings?
Cartilage rings are the structural support of the trachea, that keeps the tracheas shape from colliding in on itself.
What is the Inspiratory Reserve Volume?
The IRV is the extra amount of air that can be inspired after a regular breath movement
What is the Expiratory Reserve Volume?
The ERV is the extra amount air that can be expired after a regular breath movement
What are gills?
Gills are the ‘lungs’ of fish, they allow water to pass through them and takes/gives oxygen/waste as the fish moves, in order to keep receiving oxygen. It’s like lungs, if air passed through them
What is the larynx?
The larynx is the area of the throat that holds the responsibility of breathing, talking, and eating.
What is the epiglottis?
The epiglottis is the little muscle flap that blocks/allows food/air to go down its respective tube
What is Diffusion?
Diffusion is where something from a low concentration moves to a high concentration, in an attempt to balance concentration
What are the lungs?
The lungs are a pair of large sacs that provide an area for air to enter and come in contact with blood, in order for diffusion
What is the bronchus?
The bronchus is the tube that connects the windpipe to the lung
What is the glottis?
The glottis is the middle region inside your larynx. It contains the vocal folds in order for sound to be produced.
What is countercurrent flow?
Countercurrent flow is used in gills. The water passing by is flowed in one way while the blood is flowing the other, for the most diffusion-surface possible.
What is cellular respiration?
Cellular respiration is when cells use oxygen and glucose to produce energy (ATP)
