zsírréteg

Zsír(réteg) refers to a layer of adipose tissue found in animals and humans. This tissue is primarily composed of adipocytes, which are specialized cells for storing energy in the form of fat. Zsírréteg serves several important biological functions.

One of the primary roles of zsírréteg is insulation. It helps to maintain body temperature by trapping heat and preventing its loss to the environment, which is particularly crucial for animals living in cold climates. Zsírréteg also acts as a protective cushion for organs and tissues, absorbing shock and preventing damage from physical impact.

Furthermore, adipose tissue is a significant energy reserve. When the body requires energy and other sources are insufficient, the stored fat in zsírréteg can be broken down and utilized. This function is vital for survival during periods of fasting or increased metabolic demand. In humans, zsírréteg is distributed throughout the body, with specific areas having a higher concentration, such as subcutaneous fat beneath the skin and visceral fat surrounding internal organs. The amount and distribution of zsírréteg can vary based on factors like genetics, diet, age, and physical activity levels.
