4. Endocrine system – works closely
With nervous system to maintain
Regulation & homeostasis.
Consists of many glands & organs
That release hormones into blood
stream

5. Hormones – special chemical
Messages(usually liquids)
sent to the body
Through the blood – they are
Shape specific .

7. Pituitary gland – “master gland”
In base of brain.
Controls all other glands

Progesterone
Estrogen – stimulates ovulation
And secondary sexual characteristics
Testes – testosterone – stimulates
Sperm production and secondary
Sexual characteristics.

11. Please

quiz
Pituitary
Thyroid
Adrenal glands
Pancreas
Testes-ovaries

12. Negative feedback – endocrine System operates on this mechanism
The level of one hormone in the
Blood causes another hormone to
Be released or not. Ex = blood
Sugar is high – insulin is released
By pancreas To lower it to keep
homeostasis `

14. Excretory System
Excretion – removal of wastes
Produced by the bodies cells
(metabolic waste)
Excretory system – includes skin
Lungs, kidneys and liver

16. Kidneys – filter waste from the Blood. Composed of thousands
Of filtering units called nephrons
                                                     

21. All the bodies blood is constantly
Passed through the kidneys to
Have wastes filtered out. ( Every
7 minutes)
Ureters – tubes that carry waste
(urine) to the bladder from kidney
Bladder – stores urine

22. Urethra – expells urine

Salt and urea. – Sweating regulates
Body temp = maintains ???????
Lungs – excrete CO2 and water
Vapor

25. Liver – breaks down amino acids
(proteins) and old red blood cells
and filters toxins from digested
food - Has over 500 other jobs.
