Answers
The pleural lining of the lungs – answer Parietal pleura
Visceral pleura
Pleural space
3 muscles involved in inspiration and expiration – answer Diaphragm, internal, and
external inter costals
Minute ventilation formula – answer Minute ventilation= tidal volume x breathing rate
What is the difference between lymph and interstitial fluid? – answer Lymph is located
around lymphatic vessels, interstitial fluid is around cells
What types of diseases attacks your own cell? – answer Autoimmune
Exhalation begins when – answer inspiration muscles relax
Which cells are targeted by HIV? – answer T helper cells
How does Boyle's law relate to breathing? - answerAs the lungs expand, the volume

Can you get sick from the flu vaccine? What would cause someone to get sick after
receiving it? - answerWhen you get vaccinated you receive either an inactive form of the
virus/disease, or a small portion that is active. If you get sick afterwards, this is your

immunity or the third line of defense is when the lymphocytes (T and B cells) memorize
this pathogen so if or when you get sick in the future and get the full blown virus or
disease, your body is more prepared to kill it faster due to recognizing it through
memory and from killing it once before.
