Purpose
The respiratory system's main job is to supply the body with this gas and remove carbon dioxide.
What is Oxygen (O2)?
Air enters the trachea after passing through this structure, commonly known as the "voice box."
What is the larynx?
What is a high surface area?
This is the amount of air that always stays in your lungs, even after you blow out as hard as you can.
What is Residual Volume?
This is the primary treatment for a bacterial respiratory infection like bacterial Pneumonia.
What are antibiotics?
This describes the flow of molecules from a high concentration to a low concentration.
What is diffusion?
This is the physical pathway air takes, in order, from the trachea to the alveoli.
What are the bronchi and then the bronchioles?
These are the microscopic blood vessels that surround the alveoli to allow for gas exchange.
What are capillaries?
This device is used by doctors to measure the volume of air a person can inhale and exhale to create a lung volume graph.
What is a spirometer?
This is a serious illness characterized by an infection from a bacteria.
What is tuberculosis?
This is what happens when we complete inspiration.
This specific phase of respiration involves the exchange of gases between the atmosphere and the blood in the lungs.
What is external respiration?
These are the products of cellular respiration.
On a spirometry graph, this is calculated by adding Tidal Volume, Inspiratory Reserve, and Expiratory Reserve.
What is Vital Capacity?
This genetic disease causes the body to produce abnormally thick, sticky mucus that clogs the lungs and leads to life-threatening infections.
What is Cystic Fibrosis?
This term refers to the entire process of moving air in and out of the lungs.
What is pulmonary ventilation?
To exhale, the diaphragm does this, which increases the pressure inside the chest.
What is relax?
This specific phase of respiration involves the exchange of gases between the body cells and the blood in the lungs.
What is internal respiration?
This is the extra volume of air you can breathe in above a normal, resting inhalation.
What is Inspiratory Reserve Volume (IRV)?
These are common symptoms often associated with sleep apnea.
The way that the cardiovascular and respiratory system work together.
What is... the respiratory system pulls O2 into/pushes out of the lungs where it uses diffusion to get the gases in/out of the blood, while the cardiovascular system is able to get the gases throughout the body quickly using blood. The cardiovascular system will then use diffusion one O2 arrives at body cells.
This is the pathway that air takes as it enters our blood.
What is the nose -> nasal cavity ->pharynx -> epiglottis ->larynx --> trachea -> bronchi -> bronchioles -> alveoli -> blood
While most oxygen travels on hemoglobin, most carbon dioxide is actually transported in the blood as this ion.
What is bicarbonate (HCO3-)?
Many high-altitude populations have more red blood cells, but Tibetans are unique because of this reason.
What is... ESPA1 Gene. Their bodies do not produce excess red blood cells to increase oxygen levels, which would thicken blood. They compensate for the low levels of oxygen in other ways.
This is the clinical outcome for individuals with cystic fibrosis.
While there is no cure for CF, life expectancy has significantly increased. Usually patients are given antibiotics to prevent and fight infections, anti-inflammatories, and they practice airway clearing techniques. Even with these clinical interventions vital capacity can decrease over time as residual volume will increase.
