The Digestive System
The job of the digestive system is to break down food into substances to provide the body with vitamins, energy and minerals. The digestive system is approximately 20 to 30 feet and acts in stages to be able to digest the food we eat.
The first stage is chewing which helps us break down small pieces of food making it easier to digest and swallow. Saliva in our mouth has special enzymes that help us break down foods like starchy foods.
The second stage is swallowing, for this process our tongue helps us to push what we eat to the back of the throat where special muscles are located which force the food down a tube called the oesophagus to our stomachs. Whilst this is happening a flap called epiglottis separates from our windpipe to make sure food doesn’t go down the wrong way.
Muscular System
Within our body there is 3 different types of muscles, these are smooth muscles, cardiac muscles and skeletal muscles which each have different jobs to do.
Smooth muscles can be found throughout your body from in your digestive system, in blood vessels and in your eyes. These muscles operate on their own and are not controlled by the brain. These muscles move food through your digestive system and they also regulate the blood flow in the body. These muscles are smooth in appearance.
Cardiac muscles can only be found in the heart. These muscles operate on their own and are not controlled by the brain. Electrical pulses flow through because the cells of your heart care cemented to each other.
Skeletal muscles are mostly attached to bones and they are used for movement within the body. These muscles do not operate on their own, the brain tells the skeletal muscles what to do.
Immune system
The immune system identifies a variety of threats against the body like viruses and parasites by identifying from the bodies healthy tissue.
