1. Explain the physiologic processes involved inhomeostatic regulation of temperature, pulse,respirations, and blood pressure.
During the mid-1990s, the death of 2 top basketball players was linked to the use of cocaine. Referring to homeostatic mechanisms, explain why using a stimulant before exercise is dangerous.
. Nicotine, one of the components of cigarettes, slows cilia" lining the respiratory tract, causes blood vessels to constrict, and increases heart rate. Another component of cigarette smoke is carbon monoxide. As you have read, carbon monoxide competes with oxygen for binding sites on the hemoglobin molecule found in red blood cells. Analyse the data presented, and describe the potential dangers associated with smoking.

1. Is this statement correct or incorrect? Explain. During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain. Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.
3. Explain how a change in carbon dioxide will lead to a change in pH, and how this reaction can affect respiratory rate. (no need to do what is instructed) Thank you for your help!
