Three examples of a day in my life:
1) My early morning workout consists of cardio - such as running and biking for multiple miles. This causes my body to activate my sweat glands. My sweat glands are activated in order for my body to secrete sweat, excrete waste, and regulate water, salt, and temperature. This is an example of the exocrine system in action.
2) After my workout, I eat breakfast. In order to digest my breakfast, my pancreas will be activated. The function of my pancreas is to secrete pancreatic juice that contains enzymes, and aid in digestion. This is another example of the excocrine system.
3) After the rest of my day, it's time to go to bed. In order for me to feel tired, my body releases melatonin. This is done by the pineal gland. The pineal gland is responsible for secreting melatonin, and regulating the sleep cycle and other biological rhythms.
