Question
Chapter 46, Problem 11TYK
Summary Introduction
To review:
Smoking has traditionally been considered to reduce the ability of athletes to run without becoming exhausted.
Introduction:
The respiratory tract contains an epithelial layer, which is lined by cilia. Cilia clear the respiratory tract of bacteria and dust particles. Tobacco smoke paralyzes the cilia and interferes with the clearing process of the respiratory tract.

One form of cheating utilized by endurance athletes is called blood doping, which relates to our study of cellular respiration. “Blood doping is the misuse of certain techniques and/or substances to increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance.” Definition from https://www.wada-ama.org/en/questions-answers/blood-doping From PED, to shaving points, bribery to drugging opponents (https://www.irishtimes.com/sport/maradona-backs-branco-s-claim-of-drug-laced-bottle-at-italia-90-1.4091470), there seems to be countless ways for athletes for gain an advantage.
