Heart and breathing rate diagram
LLLL
Read the passage and observe the graph given above
Answer the following qestions:
7.1. What could be the reason of the breathing rate of person 2 after activity to be
lower than person 1 after activity?
7.2. Define breathing rate.
What are the gases being transported and what is the substance responsible
for the transport?
7.3.
7.4.
In whom do we generally observe high breathing rate even at rest?​

Answer 1

Answer:

7.1 :During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

7.2 : Respiratory rate: A person's respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.Respiratory rate: A person's respiratory rate is the number of breaths you take per minute.

7.3 : Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to hemoglobin, or carried as a bicarbonate ion. Several properties of carbon dioxide in the blood affect its transport.

7.4 : Athlete resting heart rate. An athlete's resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm. That's likely because exercise strengthens the heart muscle.

hope this helped ;)

ik it did

mark me brainiest . thank you.
