communicate the results
Explanation:
Scientific method is a set of steps made in order to perform a proper and valid scientific investigation.
Everything starts with an observation, finding something unusual or interesting that we want to test. After choosing our field of interest, we continue to ask a question; why is something the way it is and what is the reason for that?
Every question needs an answer so we propose a possible answer or a hypothesis. Of course, this doesn't have to be correct or final explanation, but it will be the answer which will we put to the test.
After constructing a hypothesis, we need to test it through researching or experimenting in which we will obtain some date.
Results of our experiment in the form of data must be analyzed and used to confirm or denied.
These results, whatever they may be, will help us to make a conclusion which we'll finally communicate, showing it to the other researchers.
Answer: autonomic nervous system
Explanation:
The autonomic nervous system serves as a regulator of blood pressure and is also critical in the regulation of skeletal muscles blood flow during exercise.
Pulmonary ventilation increases because of a rise in tidal volume and respiratory rate to meet increased oxgyen demand.oxygen delivery during strenuous exercise is limited by cardiovascular function.
During exercise, there is an increase in physical activity and muscles cell respire more than they do when the body is at rest. The heart rate of breathing increases and this make more oxgyen to absorb into the blood and more carbon dioxide is removed
