4. 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.

spread to other parts of the body. Cancer
cells often use lymph vessels as pathways to
other parts of the body, where they continu
to divide.
e) Why does this characteristic make cancer
especially dangerous?
