What is the endocrine system?
The endocrine system is a collection of ductless glands that produce hormones and secrete them into the circulatory system. Endocrine glands work without ducts for carrying secretions towards target organs. Instead, hormones can act as chemical messengers for a large number of cells and tissues simultaneously.
How does the endocrine system work?
The endocrine system consists of many glands, which work by secreting hormones into the bloodstream to be carried to a target cell. Endocrine system hormones work even if the target cells are distant from the endocrine glands. Through these actions, the endocrine system regulates nearly every metabolic activity of the body to produce an integrated response. The endocrine system can release hormones to induce the stress response, regulate the heartbeat or blood pressure, and generally directs how your cells grow and develop.
Why is the endocrine system not responding to messenger signals?
Endocrine system diseases primarily arise from two causes – either a change in the level of hormone secreted by a gland , or a change in the sensitivity of the receptors in various cells of the body. Therefore, the body fails to respond in an appropriate manner to messenger signals. Among the most common endocrine diseases is diabetes, which hampers the metabolism of glucose. This has an enormous impact on the quality of life since adequate glucose is not only important for fueling the body, but it is also important in maintaining glucose at an appropriate level to discourages the growth of microorganisms or cancerous cells.
How does the endocrine system affect the body?
The endocrine system is involved in every process of the human body. Starting from the motility of the digestive system, to the absorption and metabolism of glucose and other minerals, hormones can affect a variety of organs in different ways. Some hormones affect the retention of calcium in bones or their usage to power muscle contraction.
Why are endocrine glands important?
These glands can help to coordinate the overall actions of the system and the body as a whole. A release of hormones from these glands can create a cascade of effects from the release of a single hormone. This makes the endocrine system one of the most complexly structured body systems.
What are the effects of hormones on the reproductive system?
Imbalances of hormones from the reproductive system are also significant since they can influence fertility, mood, and wellbeing. Another important endocrine gland is the thyroid, with both high and low levels of secretion affecting a person’s capacity to function optimally, even affecting fertility in women. The thyroid also needs a crucial micronutrient, iodine, in order to produce its hormone. Dietary deficiency of this mineral can lead to an enlargement of the thyroid gland as the body tries to compensate for low levels of thyroid hormones.
What are the functions of gonads?
The gonads also have important endocrine functions that influence the proper development of reproductive organs, the onset of puberty, and maintenance of fertility. Other organs such as the heart, kidney, and liver also act as secondary endocrine organs, secreting hormones like erythropoietin that can affect red blood cell production.
Why is the endocrine system important?
Depending on our developmental needs at whichever stage in life we are in, our endocrine system will ensure that a proper hormonal balance is in place so that we release more or less of certain hormone based on these needs. Many factors can compromise this balance, however, resulting in endocrine disease.
What is the difference between endocrine and exocrine?
Endocrine system glands are spaced throughout the entire body. They release a wide number of hormones which control the metabolism and function of other cells. Exocrine glands, by comparison , secrete substances inside and outside of the body using ducts. These two methods of transport mark the difference between exocrine and endocrine glands.

Function
Mechanism
- Endocrine glands are usually heavily vascularized, containing a dense network of blood vessels. Cells within these organs produce and contain hormones in intracellular granules or vesicles that fuse with the plasma membrane in response to the appropriate signal. This action releases the hormones into the extracellular space, or into the bloodstream...
Causes
- As an example, the long-term secretion of growth hormone in the body influences the development of bones and muscles to increase height and also induces the growth of every internal organ. This happens over the course of many years. Hormones like cortisol, produced during times of stress, can change appetite, and metabolic pathways in skeletal and smooth mu…
Structure
- The neck contains the thyroid and parathyroid glands. The thyroid gland consists of two symmetric lobes connected by a narrow strip of tissue called the isthmus glandularis, forming a butterfly-like structure. Each lobe is about 5cm in height, and the isthmus is approximately 1.25 cm in length. The gland is situated in the front of the neck, behind the thyroid cartilage. Each lob…
Overview
- Diabetes, or diabetes mellitus, refers to a metabolic disease where the blood consistently carries a high concentration of glucose. This is traced back to the lack of effective insulin hormone, produced by the pancreas, or a lack of functioning hormone receptors. Diabetes mellitus could either arise from a low level of insulin production from the pancreas or an insensitivity of insulin …
Pathophysiology
- Hypothyroidism is a condition where the body has an insufficient supply of thyroid hormones thyroxine (T4) and triiodothyronine (T3). Both these hormones contain iodine and are derived from a single amino acid tyrosine. Iodine deficiency is a common cause for hypothyroidism since the gland is unable to synthesize adequate amounts of hormone. This can arise due to damage to t…
Definition
- Hypogonadism refers to a spectrum of disorders where there is an insufficiency of sex hormones. These are usually secreted by the primary gonads (testes and ovaries) and affect the development, maturation, and functioning of sex organs and the appearance of secondary sexual characteristics. It can arise due to a low level of sex hormone production by the gonads itself, o…
Signs and symptoms
- Depending on the period of onset, hypogonadism can result in different characteristics. Hypogonadism during development can cause ambiguous genitalia. During puberty, it can affect the onset of menstruation, breast development and ovulation in females, delay the growth of the penis and testicles, and affect the development of secondary sexual characteristics. It can also i…
