What changes occur to your breathing and heart rate during exercise? why do you think these changes occur?

Explanation:

As your HR increases during exercise, your muscles, heart, pulmonary system needs to deliver more O2 to those parts of the body, for proper function. without this your muscles will rely on stored fat for energy, which causes the muscle tissue to excrete lactic acid into the bloodstream. lactic acid is known to cause sepsis and also shock. sodium, potassium, and electrolytes are needed to retain fluids in the body more efficiently.

sand 60

clay 10

silt 30
