Question

Describe the changes that took place in the human body to bring about increase in the breathing rate of the person​

Answer 1

Answer:

effectors in the lungs are triggered to ventilate (inhale and exhale) faster

Explanation:

To increase the respiratory rate so carbon dioxide is removed and oxygen brought in more quickly. At the same time, the brain sends messages to the heart to beat faster, pumping oxygenated blood to the cells more quickly.

Answer 2

Answer:

• To match the amount of oxygen required, the respiratory rate can be raised or lowered.
• Effectors in the lungs are stimulated to ventilate (inhale and exhale) more quickly in order to increase the respiratory rate, which expedites the removal of carbon dioxide and the introduction of oxygen.
• In order to pump oxygenated blood to the cells more quickly, the brain simultaneously tells the heart to beat more swiftly.
• Additionally, the depth of breathing can be changed to allow for a bigger or smaller air intake into the lungs.

Explanation:

• We modify our breathing to correspond to our activity. Skeletal muscle movement consumes energy, necessitating a greater need for sugar and oxygen.
• Blood is well-supplied to muscles, carrying nutrients like glucose and oxygen, while also removing carbon dioxide.
• When muscles contract more quickly, such as when we transition from walking to running, the heart beats more quickly (increased heart rate) to boost blood flow, and we breathe more quickly (increased respiratory rate) to increase the amount of oxygen in the blood.
