Body Systems

The real key for prevention are maintaining body systems. Keeping the body systems like our immune, respiratory and circulatory system etc.. in check are vital for our well-being. Health is the outcome of the small choices we make on a daily basis.

The immune system is like a small police force that constantly patrols every organ and tissue in your body. It works closely with the circulatory system for transportation needs and the lymphatic system for production of lymphocytes.
(A lymphocyte is one of the subtypes of a white blood cell in a vertebrate's Immune system. They are the main type of cell found in lymph, which prompted the name "lymphocyte").

The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels.... Meanwhile, the circulatory system carries hormones from the endocrine system, and the immune system's white blood cells that fight off infection.

Each of your body systems relies on the others to work well.

Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure
