How Does Digestion Works?
The human body is a combination of different systems which work in perfect harmony to make us the most advanced living creature on earth. These important systems can be classified as the cardiovascular system, the integumentary system, the musculoskeletal system, the lymphatic system, the nervous system, the gastrointestinal or digestive system, and the reproductive system.
