Endocrine glands are also known as hormone-producing glands. These glands are scattered in various parts of the body and have their respective roles in regulating organ systems. Therefore, his he alth needs to be maintained in order to function normally
The endocrine glands work by producing and delivering hormones directly to the blood vessels.
Hormones produced by endocrine glands play an important role in regulating various functions and organ systems, such as metabolism, growth and development processes and puberty, as well as controlling blood sugar, blood pressure, and heart rate.
Various Glands in Endocrine Glands
The following are various types of endocrine glands and their functions in human organ systems:
1. Pituitary Gland
The pituitary gland is a small gland located at the base of the brain. Despite its small size, the function of this gland is very large in the endocrine system. This gland is considered the 'leader' of all endocrine glands, as it can produce various hormones that regulate the functions of other endocrine glands.
Some of the hormones produced by this gland are luteinizing hormone (LH) which stimulates the production of the hormones progesterone and testosterone from the male and female reproductive organs, and thyroid stimulating hormone (TSH) to encourage the thyroid gland to produce the hormone thyroxine.
2. Thyroid Gland
The thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3) which are responsible for regulating the body's metabolic processes. In addition, this hormone also plays a role in the formation of bone tissue, regulation of body temperature, and the development of the brain and nervous system.
3. Parathyroid glands
This gland releases parathyroid hormone which plays a role in regulating calcium levels in the blood. The task of this hormone is assisted by the hormone calcitonin which is produced by the thyroid gland.
4. Adrenal Gland
The adrenal glands are divided into two parts, namely the cortex and the medulla. The cortex is responsible for producing steroid hormones that regulate metabolism, the immune system, the body's response to stress, and the development and function of sexual organs.
Meanwhile, the medulla plays a role in producing the hormone epinephrine or adrenaline to increase blood pressure and heart rate.
5. Pancreatic gland
The pancreas gland produces two hormones, namely the hormone glucagon and the hormone insulin. Glucagon functions to store and increase blood sugar levels, while insulin functions to lower blood sugar levels.
6. Reproductive glands
The male reproductive glands or testes are located in the testicles or scrotum, while the female reproductive glands, namely the ovaries or ovaries, are located in the pelvis.
The testes produce the hormone testosterone to produce sperm, while the ovaries produce the hormones estrogen and progesterone which play a role in supporting pregnancy and regulating the process of ovulation and menstruation.
Just like other organ systems in the body, the endocrine system can also be affected.
If the function of the endocrine glands is disturbed and cannot produce hormones properly, for example, the amount of hormones becomes imbalanced due to too little or too much, this condition can lead to various diseases, such as thyroid disease, diabetes, PCOS, and hypogonadism.
The occurrence of disorders in the endocrine glands can also be caused by many things, ranging from heredity, genetic disorders, infections, or side effects of drugs, such as chemotherapy and drugs containing hormones.
Therefore, you need to keep the endocrine glands functioning properly by adopting a he althy lifestyle and regularly doing regular medical check-ups to the doctor, especially if you are at risk of experiencing abnormalities in the endocrine glands.
If you have complaints about the endocrine glands, for example, often feel restless, rapid weight gain or loss, difficulty in getting offspring, or other symptoms, you should consult this problem with your doctor so that an examination can be carried out and appropriate treatment given.
