ENDOCRINE SYSTEMRosa GutierrezKarina OcampoAlejandra Rojas

What is the Endocrine System?• Many organs make up the systems: Thyroid Gland, Adrenal Glands,

Pancreas, Ovaries (for female), Sperm (for male)• Purpose is to make your body grow into the state where it is meant

to function and be at

What does the Endocrine System do?

• Regulates mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes• Produces hormones (ex. Adrenaline system)• Also the major function of growth hormones (Pituitary Gland) • Has reproductive glands, known as the gonads, which is the main source of sex hormones

Hypothalamus• Receives information about external and internal conditions

from other types of the brain.• Responds by receiving instructions from the pituitary gland

in forms of hormones. • Coordinates the activates of the nervous and endocrine

system. • Controls body functions such as blood pressure, body

temperature, and emotions.

Pituary Gland• One of the most vital parts of the Endocrine system• These hormones can be influenced by several factors, such as

changes in seasons and emotions. • Makes different hormones that control other types of glands.• Pituitary gland is divided into two functions: anterior and

posterior lobe.

Produces growth hormones, prolactin, thyrotropotin, corticotripon

Thyroid Gland• Located in the front of the lower neck and produces three main hormones:• Thyroxine: affects body growth, metabolic rates,

and the development of bones and skeletal muscle• Triiodothyronine: maintains normal heart rate and

the rate cells burn to produce food for energy• Calcitonin: lowers blood calcium levels.

Adrenal Glands• Located on top of the kidneys• Two parts, each produce different hormones• Adrenal Cortex (Outer Part): Produce corticosteroids that controls salt and water balance. Responds to stress, metabolism, immune system, and sexual development• Adrenal Medulla (Inner Part): Produces catecholamines such as epinephrine. Increases blood pressure and heart rate when body experiences stress.

Diabetes• One of the most common diseases• Results from the pancreas not producing enough insulin or using it effectively• Insulin is important because it converts starches and sugars into energy!• Frequent urination, weight loss, thirst and extreme hunger (Type 1 symptoms)• Similar to Type 1 but also blurred vision, frequent infections, and slow to heal wounds (Type 2)

Diabetes cont.• Only treated by insulin shots, heatlhy diet, regular check up on blood pressure, and physical activity (Type 1)• Regular exercise, healthy diet, taking prescribed medicine, and check ups on blood pressure (Type 2)

10 Facts about the Endocrine System• Associated with the pancreas, hypothalamus, pituitary

gland, thyroid, parathyroid, adrenal glands, pineal body, and reproductive glands (include the ovaries and testes)

• Controls different functions by making hormones and chemical messengers.

• Release more than 20 major hormones into the blood stream• Glands select materials from the blood and gives off

chemicals• There are about 30 hormones in your body being produced

by the glands in the endocrine system.• The endocrine system controls the growth of cells.• Endocrine glands release hormones under the influence of

negative feedbacks• The hypothalamus and the pituitary gland both are the

major parts of the system• The hormones in the endocrine system carry instructions

that cause cells to change their activities• Maintains other systems’ balances (homeostasis)
