Pulmonary

Question 1

chlorine

Answer 1

-corrosive gas as it is soluble in water
forms corrosive acids (HOCl & HCl)
-inhalatation results in alveolar damage - lungs large SA, moist, site for acid formation
-LOW exposure has irritant effect - sore throat, coughing - this limits effect as it constricts airways

Question 2

what does high concentrations of chlorine do

Answer 2

direct damage to alveolar sacs
- chloring dissolves in moist alveolar sac to form acids
-pneumocytes directly damaged => oncosis
-endothelial lining also damaged
- corrosive effects - rapid breathing and wheezing, accumulation of fluid in lungs, blue colouring of skin, pain
VERY HIGH - lung collapse and death. Severe eye and skn burns

Question 3

process of chlorine damage

Answer 3

capillary fluid leaks into air space resulting in pulmonary oedema -> lung tissue swells into spongy wet mass, no gas exchange, often fatal
used as chemical weapons

Question 4

pneumocytes

Answer 4

type 1 pneumocytes - large SA

type 2
