swelling will put at risk the opening to the trachea therefore medical emergency can die as a result of sufication
what are some common lower respiratory tract infections
bronchitis
Pneumonia
bronchiolotis
What are the respiratory tracts defense mechanisms
MMES
general immune system humoral and cell mediated
respiratiry tract secretions
define cytopathic
structural changes in host cells that are caused by viral invasion
the lower respiratory tract should be sterile, true or false
true
if the epithelium involved in the MMes gets damaged what repercussions could this have
no exit from the lungs for the MM escalator, leads to secondary infections and this is what kills most people
define hypostatic
accumulations of secretions in the lungs
what is bronchopnemonia
inflammation of the lungs, arising in the bronchi or bronchioles. spills out into the lungs.
define lobar Pneumonia
inflammation of the entire lobe of lung. 95% of cases caused by streptotococi
what is bronchiectasis
pathological dilation of bronchi due to sever infective episode
what are the symptoms of Bronchieactasis
persistent cough abundant purulent foul sputum haemoptysis coarse crackles clubbing
define hypoxaemia
abnormally low levels of oxygen in the blood
define cor pulmonale
Cor pulmonale refers to the altered structure of the right ventricle that results from pulmonary hypertension that is associated with diseases of the lung
Lung conditions that cause a low blood oxygen level in the blood over a long time can also lead to cor pulmonale. true or false
true
