Pulmonary alveoli (lung alveoli)
See also: mucus cup cells, bronchi
Themes
1. Not being able to digest an (air) chunk, not being able to breathe.
2. Agony, panic.
CA phase
Increase in function, increase in lung alveoli, which on examination can be seen as lung cancer.
Biological utility
Improved respiratory function:
1. More oxygen intake to be able to flee or fight to save life.
2. Be able to emit more CO2.
Symptoms
None.
PCL Phase A
Normalization of lung function. Degradation of extra lung alveolar cells by fungi or TB bacteria, if present.
Symptoms
Extreme fatigue, smelly night sweats, fever, shortness of breath and shortness of breath, coughing up blood and bloody mucus. This used to be called lung TB; now it is usually diagnosed as lung cancer.
EC
Strong pain, chills, coughing up (a lot of) blood.
PCL-B
Declining symptoms and (prolonged) coughing up lumps of degraded lung tissue.
Hanging healing: further reduction of lung tissue, pulmonary emphysema (see also endoderm). Filled with fluid: syndrome.
Relapses or hanging healing after crisis: sarcoidosis (with scar tissue).
Constellation of pulmonary alveoli (relay for O2 uptake and CO2 excretion, see brain): hyperventilation.
