The Circulatory System
Muscular System
Skeletal System
The adult human skeletal system consists of 206 bones, as well as anetwork of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive.
Animals with internal skeletons made of bone, called vertebrates, are actually the minority, as 98 percent of all animals are invertebrates, meaning they do not have internal skeletons or backbones. Human infants are born with about 270 bones, some of which fuse together as the body develops.

These foods are often high in calories yet offer little or no nutritional value. When fast food frequently replaces nutritious foods in your diet, it can lead to poor nutrition, poor health, and weight gain. Testsin lab animals have even shown a negative effect in short duration diets. Being overweight is a risk factor for a variety of chronic health problems including heart disease, diabetes, and stroke.
According to the Robert Wood Johnson Foundation, most people underestimate the number of calories they’re eating in a fast-food restaurant. A 2013 study published in JAMA Pediatrics showed that children and adolescents take in more calories in fast food and other restaurants than at home. Eating at a restaurant added between 160 and 310 calories a day.
