Do You know That " How Hormones Control Our Life ? "

In the past, it was thought that hormones only affected the body and not the brain. We now know 

that hormones programme our brains before birth, dictating our thinking and behavior. 

Testosterone in teenage boys is 15-20 times higher than in teenage girls and the hormone flow in 

boys  is controlled and regulated by the brain as the body needs it.

At puberty, testosterone surges through an adolescent boy's body, giving him a dramatic spurt of 

growth and a body ratio of 15% fat and 45% protein. 

As he turns into an adolescent, his body physically changes to match his biological job description 

as a lean, mean, lunch chasing machine. 

Boys are excellent at sport because their bodies are hormonal ly constructed for effective

breathing and they have excellent oxygen distribution via the red blood cells to allow running, 

jumping and grappling. 

Steroids are male hormones that build additional muscle and give athletes extra 'hunting' abilities

and an unfair advantage over non-steroid takers.

Female hormones have a different effect on teenage girls. They are not regulated like a boy's 

hormones but come in huge waves over a 28-day cycle and can cause havoc for many girls and 

women due to the rise and fall of emotions that go with it. 

Female hormones change a girl's body into a ratio of 26% fat and 20% protein, much to the 

frustration of females everywhere. The purpose of the extra fat is to give additional energy for

breastfeeding and is insurance against times when food may be scarce. 

Because female hormones

fatten the body, they are used to fatten livestock. Male hormones reduce fat and build muscle so 

they're unsuitable for animal fattening.

Difference Between Male And Female hormones

 Hormones As A Proteins

Small peptide hormones consist of TRH and vasopressin. Peptides composed of scores 

or hundreds of amino acids are referred to as proteins. Examples of protein hormones

 include insulin and increase hormone. extra complicated protein hormones

 undergo carbohydrate aspect-chains and are referred to as glycoprotein hormones.

" Human Hormones And Their Functions Chart"

The main characteristic of endocrine glands is to secrete hormones without delay into 

the  bloodstream. 

Hormones are chemical substances that affect the pastime of another part of the frame 

(goal website). In essence, hormones function messengers, controlling and coordinating 

sports all through the frame..

Endocrine gland	Hormone	Main tissues acted on by hormone	Main function of hormones
Hypothalamus	Thyrotrophin releasing hormone (TRH)	Anterior pituitary	Stimulates release of thyroid  stimulating hormone (TSH)  from the anterior pituitary
	Somatostatin	Anterior pituitary	Inhibitory hormone that prevents  release of hormones such as growth hormone from the  anterior pituitary
	Gonadotrophin releasing hormone (GnRH)	Anterior pituitary	Stimulates release of follicle stimulating hormone (FSH) and luteinising hormone (LH) from  the anterior pituitary
	Corticotrophin releasing hormone (CRH)	Anterior pituitary	Stimulates catastrophically hormone (ACTH) release  from the anterior pituitary
	Growth Hormone Releasing Hormone (GHRH)	Anterior pituitary	Stimulates release of growth hormone (GH) form the anterior pituitary
Anterior pituitary	Thyroid stimulating hormone  (TSH)	Thyroid gland	Stimulates release of thyroxine and tri-iodothyronine from  the thyroid gland
	Luteinising hormone (LH)	Ovary/Testis	Females: promotes ovulation of the egg and stimulates oestrogen and progesterone production Males: promotes  testosterone release from the testis
	Follicle stimulating hormone (FSH)	Ovary/Testis	Females: promotes development of eggs and follicles in the ovary prior to ovulation  Males:  promotes production of testosterone from testis
	Growth Hormone (GH)	Bones, cartilage, muscle, fat, liver , heart	Acts to promote growth of bones and organs
	Prolactin (PRL)	Breasts, brain	Stimulates milk production in the  breasts and plays a role  in sexual behavior
	Adrenocortico-trophic hormone (ACTH)	Adrenal glands	Stimulates the adrenal glands to  produce mainly cortisol
Posterior  pituitary	Vasopressin (anti-diuretic hormone, ADH)	Kidney, blood vessels, blood components	Acts to maintain blood pressure by  causing the kidney to  retain fluid and by constricting  blood vessels
	Oxytocin	Uterus, milk ducts of breasts	Causes ejection of milk from the  milk ducts and causes constriction of the uterus during labour
Thyroid gland	Thyroxine (T4)	Most tissues	Acts to regulate the body’s metabolic rate
	Tri-iodothyronine (T3)	Most tissues	Acts to regulate the body’s metabolic rate
Parathyroid  glands	Parathyroid hormone (PTH)	Kidney, Bone cells	Increases blood calcium levels in the blood when they are low
	Calcitonin	Kidney, Bone cells	Decreases blood calcium levels when they are high
Adrenal cortex	Cortisol	Most tissues	Involved in a huge array of physiological functions including blood pressure regulation, immune system functioning and blood glucose regulation
	Aldosterone	Kidney	Acts to maintain blood pressure by  causing salt and water retention
	Androgens	Most tissues	Steroid hormones that promote  development of male characteristics. Physiological  function unclear
Adrenal medulla	Adrenaline and noradrenaline (the catecholamines)	Most tissues	Involved in many physiological systems including blood pressure regulation, gastrointestinal movement and patency of the airways
Pancreas	Insulin	Muscle, fat tissue	Acts to lower blood glucose levels
	Glucagon	Liver	Acts to raise blood glucose levels
	Somatostatin	Pancreas	Acts to inhibit glucagon and insulin  release
Ovary	Oestrogens	Breast, Uterus, Internal and external genitalia	Acts to promote development of  female primary and secondary sexual characteristics. Important role in preparing the uterus for implantation of embryo
	Progesterone	BreastUterus	Affects female sexual characteristics and important  in the maintenance of pregnancy
Testis	Testosterone	Sexual organs	Promotes the development of male  sexual characteristics including sperm development
Stomach	Gastrin	Stomach	Promotes acid secretion in the stomach
	Serotonin (5-HT)	Stomach	Causes constriction of the stomach  muscles
Duodenum  and  jejunum	Secretin	Stomach, Liver	Inhibits secretions from the  stomach and increases bile production
	Cholecystokinin (CCK)	Liver, Pancreas	Stimulates release of bile from the gall bladder and causes the pancreas to  release digestive enzymes
Kidney	Erythropoietin	Bone marrow	Stimulates red blood cell development in the bone marrow
Heart	Atrial natiuretic factor (ANF)	Kidney	Lowers blood pressure by promoting salt and water loss
Skin	Vitamin D	Small intestine, Kidney, Bone cells	Stimulates the uptake of calcium in  the small intestine, retention of calcium and release of calcium from  bone  stores
