Question

1. When exercising, a person's breathing rate and heart rate increase in order

to supply the muscles with enough oxygen to produce ATP. What systems
are involved in this scenario?

2. When a person is cold, blood vessels near the surface of the skin contract
and less heat is lost to the environment. What systems are involved in this
example of temperature regulation?

Answer 1

Cardiovascular, respiratory, and muscular systems

Cardiovascular, respiratory, integumentary (skin and associated structures) and muscular systems

Step-by-step explanation:

The cardiovascular, respiratory, and muscular systems are the systems which are involved and perform their function in the supply of oxygen for the production of ATP for the movement of muscles during exercise while on the other hand, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems are the systems that are involved for the regulation of temperature in the human body and maintain homeostasis.
