The Human Body System

The human body is a compound and highly organised system which is formed of unique cells that act as a team to carry out the specific functions necessary for maintaining our daily life. Each organ in the human body is exceptionally vital. They protect us from harmful foreign objects such as bacteria and viruses. They let us do things like breathing, talking, movements, and our ability to smell.

The circulatory system dispenses oxygen, carbon dioxide, nutrients, waste products, hormones and heat from the body to the tissues. It consists of the heart and blood vessels. The main function of the circulatory -system is to transport oxygen, hormones, and nutrients. The heart, which is the hardest working organ is located in the body’s thoracic

They are connected by tissues and ligaments which enables motions within the human body. They are also responsible for the body’s overall movements. It sustains the body’s posture and temperature. It is the mechanical movements of the body. It includes of joints, bones and muscles. Interestingly, there are 206 bones in the human skeleton which consists of calcium, phosphorus and other minerals. For example, the rib cage protects our internal organs and plays an important part in breathing. Moreover, there are two types of muscles, involuntary and voluntary muscle that can be found in the heart and digestive system which functions automatically. On the other hand, voluntary muscle, are in our biceps and triceps which are under our control. The skull which is in the skeleton system protects and construction our face and the cavity of the

The digestive systems consists of the mouth, oesophagus, stomach, liver, pancreas, small and large intestines and anus. The oral cavity is extremely vital in the process of chewing breaking down food. In addition, the saliva, which softs the food we chew comprises of enzymes that help with the process of digestion. The food that we consume goes down into the oesophagus which is basically a long tube that contains muscles which allows food down into the stomach. Both oesophagus and stomach use voluntary and involuntary movements. Our stomach contains acids known as hydrochloric acid, which helps dissolve and breaks down food. Within the digestive system is organ called liver. This organ filters out the blood that comes from our stomach. The liver is basically safe guard of all the other organs. It also purifies the chemicals that enter our body. Furthermore, the liver works closely with gallbladder, pancreas and intestines which help us with digestion and absorbing food. Underneath the liver is the gallbladder which aids in storing bile produced by the liver. In addition, the pancreas which is located behind the stomach is also connects to the small intestine (duodenum) and it contains a fluid known as pancreatic fluid. The major portion of digestion and observation takes place in the jejunum and ileum, which
