Question

Расскажите о функции печени.В чем заключается её барьерная функция?

Answer 1

Ответ:

Барьерная функция печени состоит в защите организма от повреждающего действия чужеродных агентов и продуктов метаболизма, сохранении гомеостаза. Обезвреживающее действие печени обеспечивает химическое превращение токсических продуктов, как поступающих извне, так и образующихся в ходе межуточного обмена.

Answer 2

Функции печени:
1. Обезвреживание веществ
2. Отбирание необходимых аминокислот
3. Образование мочевины (из соли аммония)
4. Накопление разрушенных эритроцитов, используемых для выработки желчи
5. Поддержание постоянства глюкозы в крови, при избытке - глюкоза превращается в гликоген

Function of the Liver

The liver is a vital organ in the human body that performs numerous functions essential for maintaining overall health and well-being. It is located in the upper right side of the abdomen and is the largest internal organ. The liver carries out a wide range of functions, including metabolism, detoxification, storage, and synthesis.

Metabolic Function

The liver plays a crucial role in metabolism, which involves the conversion of nutrients into energy and the synthesis of essential molecules. It metabolizes carbohydrates, proteins, and fats, and regulates blood glucose levels. The liver also produces bile, a substance that aids in the digestion and absorption of fats.

Detoxification

One of the liver's primary functions is detoxification. It filters and removes harmful substances from the blood, including toxins, drugs, and metabolic waste products. The liver breaks down these substances into less harmful forms that can be eliminated from the body.

Storage

The liver acts as a storage organ for various substances. It stores glycogen, which is a complex carbohydrate that serves as a source of energy when blood glucose levels are low. The liver also stores vitamins (such as vitamins A, D, E, and K), minerals, and iron. Additionally, it stores blood and helps regulate blood volume.

Synthesis

The liver is involved in the synthesis of important molecules necessary for various bodily functions. It synthesizes proteins, including blood clotting factors, albumin, and immune system proteins. The liver also produces cholesterol, which is essential for the formation of cell membranes and the production of hormones.

Barrier Function

The liver has a crucial barrier function that helps protect the body from harmful substances. It acts as a filter, preventing toxins and bacteria from entering the bloodstream. The liver's barrier function is achieved through the presence of specialized cells called hepatocytes, which line the liver sinusoids and form a protective barrier between the blood and the liver tissue.
