Gland is an organ in the human body, which is mainly responsible for secreting some chemicals, such as hormones, digestive enzymes and liquids. Glands are widely distributed in human body, including pancreas, thyroid and adrenal gland. Glands can maintain and regulate the internal environment of the human body through secretion, thus maintaining the orderly physiological state of the human body.
Lymphatic system has a very important biological function in human body. The lymphatic system not only undertakes the function of lymphatic circulation, but also removes wastes and germs from the body. Lymphatic system has a very strong immune function, which can identify and attack pathogens in and out of the body through lymphocytes and remove pathogens. These immune mechanisms play a vital role in human health.
Glands also have important biological functions. Gland secretions can help the human body digest food, regulate the body's water balance, cell proliferation and growth, and so on. For example, insulin and glucose-regulating hormones secreted by the pancreas help to maintain the blood sugar balance in the body, maintain the normal metabolic level of the human body, and also fight against some chronic diseases, such as diabetes.
Lymph glands are widely used in clinic. Malignant diseases such as lymphoma, lymphadenopathy and lymphoma are all related to the lymphatic system, and doctors can help diagnose these diseases by examining the lymphatic system. Gland diseases are also common, such as hyperthyroidism and goiter. By examining the secretion and structural characteristics of glands, doctors can help patients make diagnosis and treatment. At the same time, doctors can also achieve therapeutic effects by stimulating glands, such as using oxytocin to promote maternal delivery. The clinical application of lymph glands can not only help people find diseases early, but also help doctors make better treatment plans and methods.
