Explain the impact of personal health behaviors on the functioning of body systems.

It usually depends what body system you are talking about but in general there are many that impact health. Personal health behavior impacts the body in all sorts of ways

For example: eating habits if the person is used to eating junk food and really never eat healthy it can cause a person to create to much insulin causing them to have diabetes and sometimes become obese, from there so many other things can happen it can begin to affect your blood pressure and in some rare cases your liver enzymes get out of hand and the person can begin to lose weight but not in a good way

Another example: exercise is a personal health behavior it helps keep your body in shape and allows your to build muscle and conditioning for your lungs. Is a person has poor behavior and chooses not to exercise they can become over weight and their body slows down without exercise it affects things like your knees, your breathing and so much more. But it can also affect someone mentally they start having insecurities and sometimes it leads to things like depression.

Hope this helped!!!
