Bio Respiratory System Flashcards
(19 cards)
Bronchitis
- inflammation of the membrane that lines the bronchial tubes
- discharge of mucus, chest pains, difficulty breathing, coughing
Carbonic anhydrate
Enzyme that allows carbon dioxide to bind with hemoglobin
Emphysema
- inflammation and disintegration of the alveoli
- shortness of breath
COPD (chronic obstructive pulmonary disease)
- loss of elasticity in the lungs
- walls between air sacs are destroyed
- membrane within bronchi become inflamed
- mucus secretion increased, clogged airways
- is a progressive degenerative disorder
Asthma
- contraction of the walls of the bronchi due to allergic response
- wheezing, shortness of breath, coughing, rapid pulse, sweating
Pneumonia
- bacterial/viral infections cause the alveoli to fill with liquid
- difficulty breathing, fever, chills, chest pains,nausea
Lung Cancer
- uncontrollable growth of cells in the lungs which create rumors
- usually arise in the cells that line the bronchi and bronchioles
- coughing blood, wheezing, hoarseness
Plasma
Liquid portion of blood
Inhalation
- to take in oxygen from the environment
- diaphragm extends downwards
Exhalation
- to remove carbon dioxide from the lungs
- diaphragm pushes upward
Nasal passage
- takes in and removes oxygen and carbon dioxide
- lined with mucus and hair
Pharynx
Back of the throat and connects nasal passage to the larynx
Larynx (voice box)
Contains chords that vibrate and assist in speech
Teaches (windpipes)
A tube that carries oxygen from the larynx to the lungs
Bronchial tubes
2 large branches that transport oxygen to the bronchioles
Pleura
- fluid that surrounds the lungs
- maintains a moist surface for the diffusion of gases
Bronchioles
Small branches that extend from bronchial tubes to the alveoli
Alveoli
- tiny air sacs
- assist in the diffusion of carbon dioxide and oxygen from the blood to lungs
Diaphragm
Muscle that assist in inhalation and exhalation
