perspiration. Such physical effects are caused by Adrenaline. Adrenaline is a hormone that is released from a person’s adrenal medulla during emergency situations but does not have psychoactive effects. It is released into the person’s body from the adrenal glands located above the kidney. It is commonly referred to as a “fight-or-flight” hormone‚ because of its effects in increasing the supply of glucose and oxygen directed at a person’s brain and involuntary muscles. This allows the person to have better

Endocrine Glands The endocrine glands are the glands of the endocrine system which secret hormones directly into the bloodstream. The endocrine is located in different parts of the body and some important endocrine glands include the pancreas‚ testes‚ ovaries‚ thyroid gland‚ adrenal glands and the hypothalamus. The adrenal glands are located near the kidneys and their function is to release stress responsive hormones. These hormones include adrenaline and noradrenaline. The adrenaline glands also affect

Thyroid glands control how human body uses energy. The thyroid produces calcitonin‚ which plays role in calcium homeostasis. In such a way‚ the thyroid contributes to the regulation of the level of calcium in human body. Parathyroid glands are located behind thyroid and produce parathyroid hormone in response to the low calcium level stimulating the production of calcium and balancing the amount of calcium in human body. In such a way‚ thyroid generates calcitonin‚ whereas parathyroid glands regulate
