The document discusses how the respiratory and cardiovascular systems respond to increased demand for oxygen during exercise. It explains that the respiratory control center detects changes like decreased pH and increased CO2 and stimulates deeper, faster breathing to increase lung volumes and gas exchange. More oxygen is carried by hemoglobin in the blood and diffused into working muscles. Heart rate also increases through autonomic control to deliver more oxygenated blood where it is needed.

Physiological changes During Aerobic ExerciseAnand Vaghasiya
Exercise induces more activity in the whole body almost every system of the body affected by exercise.
Increasing muscular activity demands the more Oxygen and red blood cell supply to the muscular tissue.
So what is Physiological changes During Aerobic Exercise? explained in detail.
Changes in Cardio-Vascular System
Changes in Respiration
Changes in Blood System
Endocrine functions
The Fick principle
Oxygen delivery or oxygen consumption ( VO2 )
Arterial venous oxygen difference (a-v O2 difference )

Like heartbeat, breathing must occur in a continuous, cyclic pattern to sustain life processes.
Inspiratory muscles must rhythmically contract and relax to alternately fill the lungs with air and empty them.
The rhythmic pattern of breathing is established by cyclic neural activity to the respiratory muscles
