Introduction
The human internal organs include the lungs, which are important respiratory organs; the heart, which delivers oxygen and blood throughout the body by contracting; and the liver, which breaks down toxic substances originating from inside or outside the body. The liver also secretes bile, which is transported via bile ducts to the gallbladder for storage and release, aiding in fat digestion and absorption. In addition to these organs, there are the stomach, pancreas, and kidneys, each performing distinct functions.
Under normal circumstances, the human body contains internal organs such as the lungs, heart, and liver. The details are as follows:
1. Lungs
The lungs are oval-shaped and located within the thoracic cavity, divided into the left and right lungs. They cover the heart and are vital respiratory organs that maintain normal bodily functions. They perform ventilation and gas exchange, provide defense mechanisms, regulate acid-base balance in the body, and store blood.
2. Heart
The heart is shaped like a peach and sits above the diaphragm, slightly to the left between the two lungs. It consists of the left atrium, right atrium, left ventricle, and right ventricle. Its primary function is to pump blood throughout the body via cardiac contractions, delivering oxygen and essential nutrients to organs and tissues.
3. Liver
The liver resembles a leaf, with hepatocytes arranged neatly like leaf structures. Located in the upper right abdomen, it is relatively large and divided into left and right lobes. It detoxifies harmful substances from both external sources and internal metabolism, and produces bile, which is transported via bile ducts to the gallbladder for storage and eventual release to aid in fat digestion and absorption.
In addition to these organs, there are others such as the stomach, pancreas, and kidneys. Although internal organs have different functions, they work together in coordination to carry out various physiological activities in the body. If any discomfort or symptoms arise in these organs, it is recommended to seek medical attention at a hospital promptly.
