Describe the five ways of observing superficial anatomy.
- Observe surface structure
- Dissection of tissue in cadavers
- Palpation: feeling w/ fingers
- Auscultation: listening to natural sound

What is Homeostasis?
Maintenance of a stable internal environment
What is a receptor?
A sensor that detects environmental change
What is the control center?
Where the information will be processed
What’s an effector
An organ, tissue or cells that respond
How is negative feedback different from positive feedback?
Negative feedback is when an effector OPPOSES a change from a set point while positive feedback is a SELF-AMPLIFYING cycle to elicit a large response to a stimulus.
What are the 11 body systems and functions?
- Integumentary- protects against environment
- Skeletal- Provide support, make blood, stores calcium
- Muscular- Movement, heat production
- Nervous- Sensation/control/consciousness
- Endocrine- Control/metabolism
- Cardiovascular- Nutrients and waste transportation
- Lymphatic- Immunity
- Respiratory- Gas exchange;breathing
- Digestive- Nutrients breakdown and absorption
10.Urinary- Waste removal/ electrolyte balance - Reproductive- Offspring production
