The endokrin sistem is a network of glands that produce and release hormones into the bloodstream. These hormones regulate various bodily functions, including metabolism, growth, and mood. Key glands in this system include the pituitary gland, thyroid gland, and adrenal glands. Hormones act as chemical messengers, influencing processes such as reproduction, stress response, and energy levels. The balance of these hormones is crucial for maintaining overall health, and any disruption can lead to conditions like diabetes or hypothyroidism. Understanding the endokrin sistem is essential for recognizing how our bodies function.
