Brief introduction to human organs and their functions (anatomy)

The main duty of the heart is to "pump blood", which not only delivers arterial blood to various organs and tissues of the body, but also delivers nutrients such as oxygen to various organs and tissues of the body. Venous blood flows back to the heart. Therefore, the heart plays a very important role in maintaining the normal function and metabolism of other tissues and organs.

2. Brain

The brain controls and manages all life activities of our body, including sports, emotions, logical thinking and learning. This can be said to be the most important difference between humans and animals. In fact, it is our brain.

3. Lung

The lungs are responsible for the gas exchange between our bodies. It can bring fresh oxygen to our body, and it can also discharge the carbon dioxide produced by our body. If the lungs of the body fail, our body may face great challenges.

4, liver,

The liver is a very important metabolic organ and detoxification organ. It is not only responsible for the metabolism and transformation of fat, protein, sugar and other related substances, but also responsible for the metabolism and decomposition of most toxins and drugs. Therefore, the liver is also one of the most important organs in our body.

5. Kidney

The main function of the kidney is all kinds of metabolic wastes discharged by the body itself. At the same time, we also need to maintain the electrolyte balance and acidity and alkalinity of human body. Of course, if our kidneys fail, all kinds of wastes in our bodies may lose their bodies, which will seriously affect the normal working hours.

Extended data:

Our human organs are structures composed of various tissues, which can perform specific functions. The tissue structure of an organ is consistent with its function. We often notice that some intuitive organs have a lot of tissues concentrated.

Such as eyes, ears, nose, tongue and other sensory organs, such as heart, liver, lung, stomach, kidney and other internal organs. Many organs are easily overlooked as organs. Any skeletal muscle, any skin.

Digestive organs of the digestive system:

Digestive glands include digestive glands and digestive ducts. Digestive glands include oral digestive glands, pancreas, liver and secretory glands in digestive ducts. Digestive organs include mouth, pharynx, esophagus, stomach, duodenum, jejunum, ileum, large intestine and anus.

Digestive organs participate in the functional activities of digestion and absorption, but each organ has its own function. Any organ dysfunction may affect digestion and absorption. Because there are many digestive organs and diseases, it is one of the most important links in clinical practice.
