Respiratory System Flashcards
Respiratory System function
Use the lungs & related structure to bring In oxygen from outside and move oxygen to blood to circulate . Also remove CO2 from blood and expels metabolism.
Upper Respiratory System anatomy
nostrils, nasal cavity, oral cavity, lips, jaw, tongue, uvula, pharynx, epiglottic, esophagus, larynx
How do air process through respiratory system
Air enter nostrils (nose) and through nasal cavities (to Clean the contaminants & other substances in air). Air is move through pharynx(throat) and larynx (voice box) where it move through trachea to the lung
Epiglottis
protective lid that cover opening to trachea. To prevent the person swallow food and does to enter the airway
Lower respiratory system
trachea, bronchial tubes & lungs
alveoli
It is tiny ballon- shaped air sac s that located at end of bronchioles. It is where the CO2 & O2 are transfer between blood and respiratory system
bronchiole
In your lungs, the main airways, called bronchi, branch off into smaller and smaller passageways. The smallest airways, called bronchioles, lead to tiny air sacs called alveoli.
Gas Exchange
When blood takes O2 to all the tissues of the body via the cardiovascular system. Then removes the waste product CO2 from tissues and takes it back to the respiratory system where it is eliminated out of the body.
Diaphragm
It’s a muscle that helps you inhale and exhale. Thin dome-shaped muscle that sits below your lungs and heart
Intercostale muscles
Muscles that present within the rib cage.
Inhalation
diaphragm contracts and pulls downward causing the thoracic cavity to expand. This creates a vacuum within the thoracic cavity drawing air into the lungs from outside
Exhalation
the diaphragm relaxes and moves upward. This causes thoracic cavity to become smaller forcing air out of the lungs to the outside
Chronic Obstructive Pulmonary Disease
COPD. Group of lung diseases where airflow in the bronchial structures is obstructed. Often a result of smoking.
Chronic bronchitis
One type of COPD. Airways become inflamed because of continued exposure to some type of irritant. This can be smoke or a chemical. High risk of lung infections. Lung will not go back to regular function since it is damage.
emphysema
Another type of COPD. long term loss of lung function that progresses over time. Decrease in number of alveoli & progressive destruction of walls of the alveoli resulting in difficult breathing
asthma
chronic inflammatory disease of bronchial tubes where airway become inflamed and bronchioles go into spasms, significantly reducing airway. If not flared up, lung function will go back to normal.
sleep apnea?
Obstrutive sleep apnea ?
a condition where breathing repeatedly stops & starts during sleep for a long period that cause measurable in blood oxygen levels
(OSA) Caused by muscle at the back of throat relaxing and narrowing the airway.
snoring
symptoms of sleep apnea and refers to noisy breathing caused by vibration of the soft palate
pneumoconiosis
any fibrous of lung tissues caused by dust in lung from environment or a persons occupation
asbestosis
Chronic lung disease is generally caused by asbestos particles in the lungs from working or living in an environment with asbestos
silicosis
Chronic lung disease condition caused by breathing in silica dust and occurs in specific occupations
