The human body is made up of seven main organic systems:
cardiovascular (heart and its components)
digestivo (pancreas, stomach and intestines)
endocrine (glands and hormones)
immune (protective cells)
musculoskeletal(muscles, ossa,joints, connective tissue)
nervous(brain,spinal cord and nerves)
respiratory(naso, trachea,bronchi and lungs)
Each of them plays a fundamental role in maintaining the body in healthy conditions.
And every system responds positively to healthy foods.
