Insulin was first discovered by Frederick Banting and Charles Best on July 30th 1921 when they
injected a diabetic dog with their newly discovered extract and found that it effectively lowered
the dog’s blood glucose levels to normal. After a lot more testing and cleaning of the hormone
for humans it was then first tested on a 14 year old boy in 1922 who was close to death. The test
was a success as it rapidly regained his strength and appetite.
2) Which organ produces the hormone and how does the hormone work in
the human body?
Insulin is a hormone produced by the pancreas. Insulin works in the body by acting as a key to
bring glucose levels to normal. So when the stomach breaks down food, some of it is broken
down to sugars called

3) Write about the important role of the pituitary gland? Why is it called the
master gland?
The main role of the pituitary gland is to control and help regulate the activities of other
endocrine glands. It is often called the ‘master gland’ because it controls the activities of other
endocrine glands such as the ovaries, the testes, adrenal gland and also the thyroid gland.
4) A person may suffer from a number of symptoms when they fail to regulate
the production of this hormone. What are these symptoms and describe
how this condition can be treated?
If the pancreas fails to regulate the production of insulin the person would suffer from a
number of symptoms. The name given to the condition where a pancreas either doesn’t produce
insulin at all or doesn’t produce sufficient amounts is called diabetes. So when people with
diabetes eat glucose, which is in foods such as breads, cereals, fruits, starchy

This is why blood glucose levels are higher in people
with diabetes.
There are two main types of diabetes, ‘Type 1 diabetes’ in
which the pancreas doesn’t produce any insulin and ‘Type 2
diabetes’ where the pancreas makes some insulin but it is
not produced in the amount the body needs. To stay alive,
people with type 1 diabetes depend on up to four insulin
injections every day. These insulin injections provide the
body with the insulin the pancreas fails to produce. They
must also test their blood glucose levels several times
The supply of glucose to the brain and immune system is important as competitors constantly rely on instantaneous decision making to ensure they make effective strategic moves. Glucagon is the hormone which ultimately increases blood glucose concentration by breaking down stored glycogen in muscle and fat cells, increasing the breakdown of fats and increasing liver glucose production. Each of these effects lead to an increased amount of glucose present in the bloodstream, meaning more energy for body cells. When the level of glucose in the bloodstream drops, more glucose is required in order to provide ATP for energy. The secretion of insulin by beta cells is inhibited
Diabetes is a disease that 29.1 million people have to live with; so what is it? Diabetes is a disease that occurs when a person’s pancreas stops producing insulin. Insulin is a hormone that helps the body use glucose. Insulin is responsible for delivering the glucose from the bloodstream into muscles, fat, liver, and most cells to produce fuel for the body.
Why do we need it? Medical term of sugar is glucose, which we get from food and our liver. To make it easier to understand, glucose it a fuel needed to produce an energythat helps body tissues to build up our muscles. There is number of risk factors of diabetes already known for society, such as: family history, genetics, age, geography.
Did you know that one type of diabetes is much worse than the other? Type 1 diabetes causes your pancreas to stop making insulin, and insulin is needed to survive. Type 2 diabetes causes your body to become resistant to insulin. Diabetes is a serious disease that needs to be addressed by everyone. Making healthy food decisions and exercising can help lower the chance of getting type two diabetes or help people control it.
Type two diabetes can cause many issues and problems for the person involved. For example, one can develop kidney disease due to the fact that high levels of blood sugar make the kidneys filter too much blood. Waste products start to build up in the blood and eventually the kidney starts to fail. Secondly, diabetes can also cause amputations and blindness to occur in severe matters. The cause of nerve damage and poor circulation makes the feet and lower legs at risk of amputation.
Our bodies take in the glucose and turn it into energy we can then use. When we let glucose in, we are raising our insulin and glucose levels. Insulin is the hormone in people’s bodies that grants glucose access into our bloodstreams. However, insulin keeps our blood levels from raising or lowering, and it stores the fat to use for energy later on. Unfortunately, people have no control over the insulin function, though they do have control over the types of food they eat that contain certain amounts of glucose.
These two hormones help regulate plasma glucose, also referred to as blood glucose, levels. Glucagon increases blood glucose and Insulin decreases blood glucose levels. When blood glucose levels are too low, Glucagon sends a message for the glycogen to be broken down into glucose to be released into the blood.
5. If the pituitary is so important, and Eric is not getting replacements of hormones the pituitary makes (except for the one from question 4 above), why isn’t he dead? To answer this question think through the cascade of events from the hypothalamus to effect. You will need to think about homeostatic feedback loops and the regulations of hormones. Before we can discuss why Eric is alive without a functioning pituitary gland we must first understand how the pituitary gland functions within the endocrine system.
Diabetes is a metabolic disease where the person has high blood sugar. This is either because the body does not produce insulin properly, the cells do not respond to the insulin, or both. There are three types of diabetes. Type 1 Diabetes is where the body does not produce insulin.

INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1
If you are struggling with a weight problem, then you may just want to become acquainted with this particular hormone. Hormones are the bodies special messengers and control many of the bodies functions (1). Adiponectin helps control hunger and fat loss.
OXYTOCIN: A NONAPEPTIDE HORMONE -ZAHRA KHAN, 2014BM24 Bachelor of Biomedical Sciences Gulf Medical University 4th October, 2015 ABSTRACT Neuro-peptides and administrative peptide hormones control numerous formative, physiological and behavioral procedures in creatures, including people. The nonapeptides oxytocin and arginine vasopressin are delivered and discharged by the pituitary organ and have activities on numerous organs and tissues. A forward review is given of the utilitarian part (physiology and social) of oxytocin. The use of characteristic peptides for medication improvement is discussed.
The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
