Endocrine system class 10

Endocrine system can be defined as the complex mesh of glands which are orchestrate the activities like growth, reproduction and development by releasing hormones. Hormone is a chemical substance which they travel through the blood to target cell. The study of endocrine system called as endocrinology. Functions of endocrine system : • To maintain the homeostatic condition of the body. • Play major role in growth, development and reproduction. • The endocrine system regulate the physiological activities of the body. • The endocrine system releases hormones also in stressed condition. Why hormones are important ? • Hormones play major role in the body, they are the chemical substances can be travel through the blood. • The endocrine gland produces some chemicals called hormones. • Hormones will diffuse and bind target cell. • The target cell must have specific receptor binds to which hormone binds. • There are various types of hormones. • Hypothalamus is the upper part of brain, present near the pituitary gland as we can see in the diagram. • When any stress condition occurs in the body, stress condition means other than normal condition arises in the body at that time, the first response is given by hypothalamus. • Hypothalamus gives response means, in response to a particular stimulus hypothalamus releases some ‘releasing hormones’. • These releasing hormones will act on the pituitary gland. • Pituitary gland is master of all organs, this gland releases various types of ho...

Overview What is the endocrine system? Your endocrine system is made up of several organs called glands. These glands, located all over your body, create and secrete (release) hormones. Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. Function What does the endocrine system do and how does it work? Your endocrine system continuously monitors the amount of hormones in your blood. Hormones deliver their messages by locking into the cells they target so they can relay the message. The pituitary gland senses when your hormone levels rise, and tells other glands to stop producing and releasing hormones. When hormone levels dip below a certain point, the pituitary gland can instruct other glands to produce and release more. This process, called homeostasis, works similarly to the thermostat in your house. Hormones affect nearly every process in your body, including: • Metabolism (the way you break down food and get energy from nutrients). • Growth and development. • Emotions and mood. • Fertility and sexual function. • Sleep. • Blood pressure. Sometimes glands produce too much or not enough of a hormone. This imbalance can cause health problems, such as weight gain, high blood pressure and changes in sleep, mood and behavior. Many things can affect how your body creates and releases hormones. Illness, stress an...

Insulin is created in a special non-disease-producing laboratory strain of E. coli bacteria that has been genetically altered by the addition of the gene for human insulin production. The bacteria produces the insulin which is then chemically harvested from the medium in which the bacteria is grown, purified and prepared for human use. let's look at what the endocrine system means what are the different hormones that they produce and what their functions are so let's start with what's an endocrine system well an endocrine system is a bunch of ductless glands which we are which are found in our body that's what we're gonna study what these glands are alright so what are these Occulus glands let's start with the word gland the word gland is any organ that secretes things for example something that you might be familiar with would be your sweat gland it secretes sweat onto us onto your skin your saliva gland is the one that secrete saliva into your tongue so anything that secretes stuff is what we call as a gland but you can see the saliva and the sweat glands they have a piping system they have a duct to carry their secretions to wherever they're supposed to go alright so these glands are called dark glands make sense now in contrast can you guess what ductless glands are well these are the glands that do not have a duct as you can see look at them the colored ones which we're going to talk about they don't have any ducts so where do these accretions go well they secrete thi...

The human endocrine system is a messenger system that regulates distant target organs through feedback loops of hormones released by the internal glands of an organism directly into the circulatory system. In invertebrates, the hypothalamus is the neural control node for all endocrine systems. The endocrine system is a system of glands and organs that is located all around the body. It functions similarly to the nervous system in that it controls and regulates all of the body's functions. Although the nervous system communicates through nerve impulses and neurotransmitters, the endocrine system communicates through chemical messengers known as hormones. The thyroid gland and the adrenal glands are the two main endocrine glands in humans. The study of the endocrine system and its disorders is known as endocrinology. Endocrinology is a subspecialty of internal medicine. Functions of Human Endocrine System The endocrine system regulates a variety of body functions through hormone release. Hormones are produced by the endocrine system's glands and pass through the bloodstream to different organs and tissues in the body. Hormones then instruct these organs and tissues about how to act. The Endocrine System is in control of the following bodily functions: • Metabolic rate • Development and growth of a human being • Reproduction and sexual function • Heart Rate • Blood pressure • The • Controls cycles of sleep and wakefulness • Controls the temperature of the body Human Endocrine...

Endocrine System Before we proceed with the topic, do you know who the mastermind behind these hormones is? Let us first see that. Yes! The Endocrine Glands So, what are endocrine glands? Endocrine glands are important glands of the endocrine system. They secrete their • Pituitary gland (Hypophysis) • Thyroid gland • Parathyroid glands • Adrenal glands • Pancreas • Gonads • Pineal gland These glands produce different types of hormones. These hormones induce a different and a specific response in other cells, tissues, and also the organs that are located throughout the body. We will now look at each of these glands in brief and understand their primary functions. Browse more Topics under Reaching The Age Of Adolescence • • • Pituitary gland (Hypophysis) The pituitary gland hangs from the base of the brain by a stalk. It is enclosed and also protected by a bone. It consists of a hormone-producing glandular portion and a neural portion. The pituitary gland is the master gland. This is pea-sized and is located at the bottom of the brain. They control and regulate other glands in the body. Hormones released by this gland are growth hormone, thyroid stimulating hormone, Luteinizing hormone, follicle stimulating hormone and so on. Thyroid gland The thyroid gland is located in the anterior throat. Thyroid follicles store colloid containing thyroglobulin, a glycoprotein from which thyroid hormone is derived. Parathyroid glands The parathyroid glands are located on the back of the t...
