How did temperature affect heart rate? What do you suppose is a consequence of being a poikilotherm? 2. Why is the Q10 a useful concept?

2. Breathing, or ventilation, is a cyclic process consisting of two stages, inspiration and expiration. Air only moves when there is a pressure gradient, moving from high pressure to low pressure. To ventilate, we must create pressure gradients that drive air through our airways into or out of our lungs. We need to change the air pressure in our alveoli. We achieve this using the principle described in Boyle's Law. Boyle's Law states that when temperature is held constant, pressure is inversely related to volume chamber increases, air pressure in that chamber decreases, and vice versa. By changing the size (volume) of the thoracic cage, we change pressure in our alveoli. To inhale, we must make our thoracic cage larger. To exhale, we must make our thoracic cage smaller. Label the diagram below, showing the muscles of our chest wall and diaphragm: that is, when volume of a (a) (b) (c) (d) 33

9. Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. If not treated properly, TB discase can be fatal. TB bacteria are spread through the air from one person to another. The TB bacteria are put into the air when a person with TB disease of the lungs or throat coughs, speaks, or sings. People nearby may breathe in these bacteria and become infected. People with TB discase are most likely to spread it to people they spend time with every day. Consequently. TB in incarcerated populations is a serious health concerm. Rescarchers were interested in looking at TB by dormitory wing at the local state penitentiary. The cast wing of the prison has two people per cell whereas the west wing has only one person per cell. To conduct the study, incarcerated individuals were asked in which wing they lived and whether they had TB. There were a total…
