During sustained swimming, what is the primary role of the circulatory system in supporting movement?

  2. Only increases oxygen delivery to active muscles
  3. Delivers oxygen and removes waste products from active muscles
  4. Only maintains core body temperature

\(C\)

Show Worked Solution

Consider Option C: Delivers oxygen and removes waste products from active muscles

The circulatory system simultaneously

  • delivers oxygen and nutrients to active muscles
  • removes metabolic waste products to maintain efficient movement through continuous blood flow

Other Options:

  • A is incorrect: Ignores oxygen delivery role
  • B is incorrect: Misses waste removal function
  • D is incorrect: Omits critical gas exchange function

\(\Rightarrow C\)
