Question

a. Nervous System
b. Respiratory System
c. Cardiovascular System
d. Muscular System
e. Endocrine System

Answer 1

The high heart rate and breath of Jane can be attributed to the sympathetic division of the autonomic nervous system, which prepares the body for physical activity or response to a threat.

Step-by-step explanation:

The high heart rate and breath of Jane, after stopping rowing and being at rest, can be attributed to the sympathetic division of the autonomic nervous system. The sympathetic system is responsible for the fight-or-flight response, which activates multiple systems including the respiratory, cardiovascular, and musculoskeletal systems. This response increases heart rate and breathing rate, preparing the body for physical activity or response to a threat.
