Which respiratory condition below correctly describes what happens during pneumonia

Pneumonia is where your alveoli gets filled with a substance causing breathing being difficult. This substance is attributed by germs that gets into your alveoli. Your cilia is supposed to move away mucus ( which traps bacteria ) so when you do acts that causes mucus getting into your trachea ( smoking ) sometimes your cilias don’t move some mucus and that mucus go into your alveoli. Hope this helps. Sorry this is such a long answer I like to give a lot of information

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
