The milking action of skeletal muscles (contraction), and pressure changes in the thorax during breathing
diaphragm
When we take exercise our body needs more oxygen .Our normal breathing rate do not fulfill the oxygen requirement due to which breathing rate is increased.
The number of cells depends on how large the muscle is; muscles consist of fiber bundles, which are made up of myofibrils. A sarcomere is one of the segments that the myofibril is divided into. In each fiber bundle there are multinucleate cells, which can extend the length of the skeletal muscle. So, the number of cells in a skeletal muscle depends on the size of the muscle. for example, the number of cells in one of our triceps larger than one of the small muscles in a finger.
From trees , they release co2 during breathing and release oxygen during photosynthesis
The diaphragm and intercostals for breathing
muscular activitybreathing muscle contraction peristalsis
1. Respiratory "Pump". Pressure changes that occur in the thorax during breathing. 2. Muscular "Pump". Contraction and Relaxation of skeletal muscles surrounding the veins.

...pressure changes that occur during breathing.
brcasue you are using oxyen which breakks down glucose and co2
Skeletal Muscles
It depends, which do you want to know about? Boy or Girl?
The diaphragm is a sheet of internal skeletal muscle in mammals that extends across the bottom of the ribcage. It plays a crucial role in breathing as it contracts and flattens to increase the volume of the chest cavity during inhalation and relaxes to decrease the volume during exhalation.
normal breathing is nice and easy while breathing during an asthma attack is difficult and doesnt allow you to fully use your airways.
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
During breathing a gas is expelled.
