(Endocrine) Estrella Valdez Period 6
Endocrine system
Maintain homeostasis - made up of cells, tissues, and organs called endocrine glands, that secrete hormones into body fluids - 2 major types of glands, exocrine and endocrine.
Endocrine Glands/Organs
pituitary glands/cranial cavity-to release hormones.
Oxytocin, female reproduction.=Mammary gland ADH, regulates the amount of water in your body=Kidney GH, controls your body's growth=tissues
thyroid gland/ thoracic cavity
Thyroxine and Triiodothyronine,Metabolic rate,growth and development=tissues Calcitonin, control calcium and potassium levels=Bone
parathyroid glands/ thoracic cavity
thymosins,affect production and differentiation
of T lymphocytes= T lymphocytes
pancreas/abdominal cavity- control level of blood glucose
Insulin, regulates blood sugar levels=Most tissues, muscle and liver Glucagon, promotes breakdown of glycogen=liver
adrenal gland/ abdominal cavity
Adrenaline ,increasing the heart rate = tissues Cortisol, increases sugars=tissues Aldosterone, regulates blood pressure=kidneys
reproductive glands/ peltvic cavity
ovaries, produce the egg cells=estrogen and progesterone testes, responsible for making sperm=testosterone
kidneys/ abdonmial cavity
erythropoietin, helps make red blood cells=blood cell production
thymus gland/ throacic cavity
Thymopoetin, maintain function in skin cells to brain cells=T-lymphocyte cells
pineal gland/cranial cavity - Secretes melatonin, regulation of circadian rhythms of the body
melatonin,light and darkness to body structures= brain
negative feedback
controls hormone release - hormone levels rise, hormone exerts effects - mechanism= hormones stay within the normal range - secretion inhibited by negative feedback, secretion decreases - hormones drop, inhibit is removed
non-steroid hormones produced from amino acids
Glycoproteins,Polypeptides,proteins,Peptides,Amines
positive feedback
maintained, not changed
diseases with endocrine system
Hypothyroidism-Underactivity of the thyroid gland
Hyperthyroidism- Overactivity of the thyroid gland
Hypoparathyroidism- deficiency of PTH,
Hyperparathyroidism-excess of PTH
Type 1 diabetes mellitus-cells are destroyed, so insulin
production decreases or stops
type 2 diabetes mellitus-n insulin is produced but is not recognized by cells
Addison disease-hyposecretion of glucocorticoids and
mineralocorticoids
Cushing syndrome-hypersecretion of adrenal cortical
hormones
steroid hormones derived from
cholesterol
Steroids
