Endocrine System
- Function
- Regulate growth
- Use food to produce energy
- resistance to stress
- Ph of body fluids and fluid balance
- Reproduction
- Regulate growth
- Characteristics
- Consists of endocrine glands that secrete chemicals called hormones
- Endocrine vs. exocrine glands
- Endocrine glands
- Ductless glands, secrets it's product (hormone) directly into the blood
- Ductless glands, secrets it's product (hormone) directly into the blood
- Exocrine glands
- Secrets it's product into a duct to be taken to be taken to a cavity or surface
- Secrets it's product into a duct to be taken to be taken to a cavity or surface
- Endocrine glands
- Types of hormones
- Amines
- Structural variations of amino acid tyrosine
- Includes thyroxine from thyroid gland
