The human body is a complex and beautifully evolved structure, which is made up, amongst other things, of several main organ systems. These systems have definitive functions which each have an important part to play in the function of the human body as a whole.
The integumentary system
The first system that we shall look at is the integumentary system. This system is responsible for controlling the body temperature and acting to perform the main sensory functions of the body. The integumentary system produces hormones and chemicals that are essential to the body’s regulation and functioning.
The skeletal system
This is an important system which acts as support for the body. Without a skeletal system, the human body would be a mass of organs, blood and matter with no ability to move around. The skeletal system is made up of many hundreds of joints, which make it possible to move. Above all, the skeletal system protects the other organs in the body.
The muscular system
The muscular system works alongside the skeletal system to allow movement to happen. It also generates heat in this movement, which helps regulate the body’s temperature.
The nervous system
To be able to interact with their surroundings, humans have a nervous system. This system sends messages all around the body, keeping the body working internally as well as controlling actions and thoughts.
The circulatory system
In order to have a good immunity, it is important that white blood cells and antibodies are transported around the body. This is facilitated by the circulatory system. The circulatory system carries various other products around the body such as oxygen in the blood and a steady body temperature is also maintained with this system.
The Respiratory system
The body requires oxygen to function. This oxygen is taken in using the body’s respiratory system. As the oxygen travels around the body, it is converted to carbon dioxide, which is a waste product, so the respiratory system expels this gas too.
The Digestive System
To receive the necessary nutrition, minerals and vitamins that the body needs to replenish cells and blood, humans need to eat and drink. The digestive system facilitates the intake of food, then breaks it down. Useful elements are absorbed into the body whilst waste products are excreted by the digestive system.
The Urinary Sytem
This relatively small system cleanses the waste from blood to keep a safe acidity level, balance the body’s water content and expels the waste in the form of urine.
The Reproductive system
This is possibly one of the most important organ systems for mankind to survive as it triggers the hormones to drive the desire to reproduce. The fertilization, development and the birth of babies are carried out by this system, thus continuing the human cycle.
