The Endocrine System

Parts of the Endocrine System

Hormones makes your body change during puberty Hormones are chemical substances produced

in certain glands that help to regulate the way your body functions. They are produced by organs of the endocrine

system Endocrine System is the system of glands

throughout the body to regulate body functions.

Glands and Hormones

Each gland makes one or more specific hormones

Hormones act like chemical signals They tell your organs and tissues what to do

A major role of the endocrine system is to control metabolism Metabolism is the process by which the body

gets energy from food.

Parts of the Endocrine System

Parathyroid Glands- regulate levels the calcium in the blood

Pituitary Gland- regulates body’s growth and development.

Thyroid gland- controls rate of metabolism. Adrenal Glands- controls the body’s response to

emergencies and excitement Pancreas- controls the level of sugar in the blood. Ovaries- controls sexual development and the

maturing of eggs Testes- controls sexual development and the

production of sperm.

Diseases of the Endocrine System

Diseases develop if there is too much or too little of a hormone produced

Diabetes is a major disease It is when the body doesn’t produce enough of

the hormone called insulin Or doesn’t respond to the insulin that is produced.

Insulin lowers the amount of sugar in the blood People with diabetes have too much sugar in the blood

If not managed well people can suffer from Poor circulation, nerve damage, heart disease,

kidney failure, or blindness

DIABETES

TYPE 1 TYYPE 2

Germ fighting cells attack the cells of the pancreas

Pancreas makes insulin

Body doesn’t produce enough insulin Too much sugar in the blood

People must inject themselves with insulin on a regular basis

Not doing so can lead to coma or death

A person can produce insulin, but the body can’t use it well. Usually develops in adulthood

Common in people who are overweight People feel tired and sick to

their stomachs People with type 2 diabetes

need to watch their diet and exercise regularly.

Thyroid Disease

This will effect metabolism If the gland doesn’t make enough hormones to

regulate metabolism you can develop hypothyroidism You will feel tired, cold, dry skin and gain extra

weight Can delay growth in teens

A thyroid replacement hormone can treat people with hypothyroidism. Hyperthyroidism is the opposite of hypothyroidism

Thyroid produces too many hormones Excessive sweating, excessive eating, weight loss,

tremors, and muscle weakness.
