Answer:
Yes, the blood pressure and heart rate return to normal after 5 minutes of physical exercise as, ANS will detect the decreasing level of oxygen and activate parasympathetic system to normalize the heart rate. The increasing of heart rate does not cause the blood pressure to increase at the same rate. After 5 minutes it return to normal as when you exercise heart rate speed up so that is why more blood reach in the muscles so it cause high heart rate and blood pressure for some minutes.
Answer:
The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. ... They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.
Explanation:
Answer:
Negative feedback.
Explanation:
Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.
The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.
Thus, the correct answer is option (c).
