~~ Homeostasis~~

Homeostasis is the process of maintaing balance in the body by all the body systems working together in order to keep balance throughout the body when the external environment causes a change in it. For example, when the temperature increases, your body temperature rises and your endocrine system causes you to sweat in order to cool down, maintaining temperature balance. Another example is when you exercise, the carbonic acid levels in your blood increase. Your body senses the increase in the blood pH, and sends a message to the brain causing the diaphragm to contract more frequently, bringing in more oxygen to the body and getting rid of the excess carbon dioxide produced as waste by cells increased activity. The oxygen in the lungs then diffuses into the blood through the alveoli walls and the carbon dioxide diffuses out of the alveoli walls to exit the body. All the body systems work together in order to achieve and maintain one goal, balance throughout the body at all times.
