Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are t…

Omar is snorkeling (surface swimming with a tube in his mouth to maintain breathing while his face is in the water). a. The snorkel tube is 35.0 cm in length and 1.4 cm in radius. How does this affect Omar's breathing? Calculate the increase in relative resistance contributed by the snorkel tube. b. What is dead space and how does that affect snorkeling? Explain your answer, assuming the snorkel tube is a round cylinder and cylinder volume is πr²L. How does the snorkel tube affect alveolar ventilation (assume a ventilation rate of 13 breaths/ min, tidal volume of 600 mL, and normal dead space volume of 150 mL.)? If normal alveolar ventilation is 4200 mL/min, how must Omar breathe during snorkeling compared to normal? c. Omar loves snorkeling, but wishes he could go a little deeper. He decides to create a longer snorkel tube to try to achieve this desire. He isn't sure how radius figures in, so he makes two tubes of 80 cm length, one with a 1.6 cm radius and the other with a 2.2 cm…
