And the Digestive system
The stomach is a muscular sac that is located on the left side of the abdominal cavity, just inferior to the diaphragm. In an average person, the stomach is about the size of their two fists placed next to each other. This major organ acts as a storage tank for food so that the body has time to digest large meals properly.
The small intestine is a long, thin tube about 1 inch in diameter and about 10 feet long. It is located just inferior to the stomach and takes up most of the space in the abdominal cavity.
The large intestine is a long, thick tube about 2 ½ inches in diameter and about 5 feet long. It is located just inferior to the stomach and wraps around the superior and lateral border of the small intestine.
- The liver has over 500 different functions, one of which is producing bile to break down digestive fats
- The stomach of an adult holds up to 1.5 liters of food and food stays here for 2 to 3 hours
- Muscles contract and relax in the esophagus to push food down to the stomach — it works even when you’re upside down!
Your Skeletal system is all of the bones in the body and the tissues such as tendons, ligaments and cartilage that connect them.
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight.
The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells.
Food is fuel for your body. It has a direct impact on how you feel as well as on your overall health. Fast food isn’t necessarily bad, but in many cases it’s highly processed and contains large amounts of carbohydrates, added sugar, unhealthy fats, and salt (sodium).
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. Testing 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.
