The human body is made up of several large parts that perform specific functions in coordination with each other. These large parts are called organs and are located inside the body. These organs are sometimes referred to as private or secret parts of the body as they are not easily visible. Each one performs a particular function and is important for the body to work well. It is necessary to provide proper care and hygiene for these private organs so as to keep them healthy.
The human brain is an organ that can be found in the head. It has a number of different functions such as memory storage, speech production and the ability to think. It controls the functions of other organs and can also help in performing complex tasks. It also receives impulses from nerves in the rest of the body and responds to pain and other stimuli.
There are 78 major internal organs that make up the human body. These are often referred to as body organs as they are recognizable in size, shape and location within the body. The functions that these organs perform are what give rise to the various body systems. When a group of organs with similar functions come together, they are referred to as a system.
Among the most important organs are the heart, kidneys and liver. The heart is responsible for pumping blood to the rest of the body delivering oxygen and nutrients while taking away wastes. The liver is found in the abdomen beneath the diaphragm on the right side and processes the components of the blood to maintain the same composition. The kidneys are a pair of muscular organs that are located in the pelvic cavity and are responsible for removing wastes from the body.
All these organs are connected to each other through a network of veins and arteries. This allows them to distribute the oxygenated blood in all parts of the body and also collect the deoxygenated blood back from each part of the body.
In order to function, the human body requires a variety of substances such as water, proteins, fats, carbohydrates and vitamins. The stomach and the small intestine are where food, drink and oral medications begin their process of digestion in the body. Nutrients and medicines are then absorbed through the walls of the stomach and small intestine and into the blood stream for further processing.
Other substances like hormones are released into the bloodstream to allow chemical communication between organs and other anatomical structures. These enable muscles to contract, nerves to send messages and the heart to beat. They are also responsible for the movement of cells throughout the body and regulating bodily functions such as temperature and blood pressure.
