Question

(B) Rani observed her pulse rhythm in normal conditions as well such as while climbing
stairs, running, etc.
() When do you think her pulse rate goes up ?
(in) What does the pulse rate show?
(iii) What is the relationship between the heart beat and the pulse?
(iv) Can we say, the pulse rate is always equal to the heart beat?​

Answer 1

Answer:

*her pulse rate can go up while she is doing some physical exercises

*the pulse rate shows the bpm of heart which is heart beat per minute

*as ur heart beat faster or slow the blood circulates faster in the veins or arteries of heart which results in high or slow pulse rate

*The pulse rate is exactly equal to the heartbeat, as the contractions or relaxation of heart increases it also gives same effect to your pulse also
