The Amazing Body Systems

Hello my name is Nidhi I will teach you about the systems today.It is important to know about it.Did you know that you have 6 important systems in your body? Well you do! There is a main task for each system.
The first body system is the Respiratory system. The Respiratory system’s most important task is providing oxygen to the entire body. When the lungs contract and relax they take in oxygen and excrete carbon dioxide back through the system and out through the nose or mouth.

The second body system is the skeletal system, it’s main task is maintaining the shape of the body with bones and joints. The skeletal system includes bones, ligaments, tendons and joints. Important nutrients such as calcium are stored in bones. WOW!

The third system is the Muscular system, it’s main task is to make sure all the muscles are activated in every body movement including pumping the heart ,smiling and moving bones. The heart is made up several muscles called cardiac muscle. Did you know that? The fourth system is the nervous system. It’s responsibility is to transport all kinds of messages from one part of the body to another especially to and from the brain. Some of the key components of this system include the brain,spinal cord,nerves and neorons.The comunication is rapid and leads to the brain relising chemichals in response to the pain. The fifth system is the Digestive system. It includes the mouth,esophagus,stomach.small intenstine,large intenstine(colan), rectum and anus.The main task is to allow organs to pass through and be broken down or absorbed.Once the food are digested they are excreated through bowel movements or urination. The sixth system is the circulatory system.It includes the heart,lungs and the blood vessals.It’s main task is to rest the body to receive oxygen.The heart pumps blood through the blood through the blood vessals and the lungs absorbed oxygen and emit it to the blood.
