Hormones secreted by the eight major glands of the human body

The pituitary gland is a very important gland and is known as the commander-in-chief of the eight major glands. The brain directly stimulates this gland to produce various hormones, and transmits the hormonal "messages" to all other parts of the lower body. When the pituitary gland malfunctions, the human body will develop many diseases, and the body will develop in an abnormal direction, or become very fat, too tall, or too short. Gigantism and dwarfism are caused by malfunction of the pituitary gland. Why do women look more beautiful when they are in love? It is because the estrogen secretion is more active under the command of the pituitary gland.

2. Pineal gland: melatonin

The pineal gland (also known as the naked eye or the third eye) is generally considered to be our biological clock, and all regular events in our body are related to it. The patterns of life, work, and even women’s menstrual cycle are all related to it. The pineal gland secretes many subtle hormones that are sufficient to affect all organs in the body. The hormone that can be isolated now is called melatonin. It can delay aging, enhance immune response, give people a sense of the universe, increase tolerance to pain, reduce sexual impulses, and reduce sleep. And it can be converted into neuroendocrine responses from environmental conditions such as light. The deeper we sleep, the more melatonin the pineal gland secretes, and the more soundly we sleep, the more melatonin the pineal gland secretes. The pineal gland and melatonin are also related to the pigmentation of human skin, which is why when people get enough sleep, their skin appears more radiant and fair. Therefore, when some people have symptoms of poor sleep and irregular life, they must pay attention to the regulation of the pineal gland.

3. Thyroid: thyroxine

The thyroid gland in the neck controls the body's metabolism. It also regulates the amount of heat and energy produced by the body and promotes digestion and growth. If the thyroid gland secretes abnormally, both physical and mental health will be seriously affected. If the thyroid hormone secretion is slightly higher, you will feel nervous, irritable, etc. If the secretion is too much, the person will become very nervous, tremble, suffer from indigestion, insomnia, and lose weight rapidly. This is called hyperthyroidism. On the contrary, if the secretion of thyroid hormone is slightly less, you will feel tired, drowsy, have cold hands and feet, etc. This is called hypothyroidism. If the secretion is too little, the movements will be slow, the pulse and heartbeat will be slow, the body temperature will drop, one will be afraid of cold, speak incoherently, feel dulled, and gain weight.

4. Parathyroid glands: parathyroid hormone

The parathyroid glands control the calcium level in the blood and are responsible for normal bone growth, because bones need calcium. In addition, nerve function is greatly affected by the calcium level in the blood. If there is too little calcium, we will become nervous, impulsive and irritable; if there is too much calcium, we will be drowsy and listless. Therefore, the parathyroid gland has a very important influence on the development of bones and the normal function of the nervous system.

Why are middle-aged and elderly people more likely to suffer from symptoms such as osteoporosis? "It is because the function of the parathyroid glands has declined, which leads to problems with the body's calcium absorption! Therefore, after the age of 40, you must pay attention to the health of your parathyroid glands.

5. Thymus: Thymosin

The thymus is an important lymphatic organ of the body. Its function is closely related to immunity. It mainly secretes thymic hormones and hormone-like substances and is an organ with endocrine function. In the late embryonic period and at birth, the human thymus weighs about 10 to 15 grams, which is the period when it is relatively heaviest in life. As age increases, the thymus continues to develop, reaching about 30 to 40 grams by puberty. After that, the thymus gradually degenerates, the lymphocytes decrease, and the adipose tissue increases, reaching only 15 grams in old age.

The thymus is located behind the manubrium of the sternum near the heart. It is most active during the fetal period to build up the body's immune system. After birth, it secretes thymopoietin to strengthen the immune system. Its basic function is to mark each cell with a recognizable mark to prevent immune cells from rebelling and destroying our body's own cells, enabling the body to resist the spread of disease.

Therefore, the thymus is in charge of our body's immune system. If the thymus function declines, people are more likely to get sick and catch a cold. When you go to the hospital, the doctor will recommend a medicine called thymosin for people who often catch colds. However, once thymosin is injected, the body's own thymus secretion will become weaker. Therefore, people also call the thymus the remote control for colds. People who are prone to colds must pay attention to the maintenance of the thymus.

6. Adrenal glands: adrenaline

The adrenal glands are located just above the kidneys. They can cause the body to generate heat suddenly. The adrenal glands are particularly important when emergencies occur. When facing danger or urgent events, such as fighting the enemy, rescuing a child who is about to drown, escaping a fire, etc., the adrenal glands will immediately deliver their secretions (i.e. adrenaline) into the blood. Adrenaline can accelerate the heartbeat, dilate blood vessels, and flow into the muscles with the blood. Therefore, the muscles can obtain more energy from the sharply increased blood and give full play to their work efficiency. It stimulates the sweat glands, so even though the body heats up due to sudden exertion, it is still able to dissipate the heat through sweating. In addition, adrenaline also sends a signal to the liver to send its stored sugar into the blood to provide the additional heat energy needed by the body. If adrenaline is secreted too little, the ability to adapt in dangerous and urgent situations will be greatly reduced. On the contrary, if the secretion is excessive, the body and mind will always be in a state of tension. The adrenal gland is also called the "stress hormone," which is related to the body's stress. When people feel high pressure at work or in life, it means that the adrenal gland function has declined. At this time, we should pay attention to regulating the function of adrenal glands.

7. Pancreas: Insulin

The pancreas is scattered among the pancreatic digestive acini. It secretes a digestive hormone called insulin, which reduces the sugar content in the blood. If there is a lack of insulin, blood sugar will rise and some of it will be excreted in the urine as sugar in the urine, which is called diabetes. On the contrary, if too much insulin is secreted, some symptoms of hypoglycemia will appear, such as weakness, tremors, dizziness, nervous tension, restlessness, etc. Excessive secretion of insulin makes it easy to gain weight, which is what we call “even drinking water makes you fat”. It is also easy to rebound after losing weight. Some people are not overweight, but have thick legs, arms or waist. This is due to unbalanced fat distribution caused by unbalanced insulin secretion. Therefore, as long as this type of people pay attention to the maintenance of their pancreas, they will find surprising changes in their body shape after about half a year.

8. Gonads: androgens, estrogens, and progesterone

Women's gonads secrete three hormones: androgen, estrogen and progesterone. Many people think that only men secrete androgens, which is wrong. Both men and women produce androgens and estrogens in their bodies, but men produce more androgens while women produce more estrogens. These hormones are related to the body shape of men and women. If the ratio of these sex hormones is abnormal, women will become masculine and men will become feminine. Androgens can increase muscle energy, give people creativity, sexual ability, and physical strength, and are directly related to human sexual desire. This is why some women are very beautiful but sexually frigid and often feel physically exhausted and feel tired after walking a short distance. This is because the body secretes too little androgen. Estrogen can increase the body's fat content, making people more emotional and thoughtful. Estrogen is also known as the "beauty hormone". Women who secrete more estrogen generally have delicate skin, fine pores, and fuller breasts. Women also have a unique hormone called progesterone, which is responsible for fertility.

Progesterone and estrogen are inversely proportional. When progesterone is high, estrogen is low, and vice versa. If the sex glands are unobstructed, there will be better vitality. If the sex glands and hormones are unbalanced, women will begin to age. After the hormones are balanced, women will really be like women, with enchantment, charm and natural appeal.
