1. 30.1 Organization of the Human Body
- Homeostasis
- Feedback Inhibition

2. Organization of the Human body
Cells (smallest)
Tissues
Organs
Organ system (largest)

3. Cells The basic unit of structure of the human body.
Tend to be specialized in multi-cellular organisms.

4. Tissues
A Tissue is a group of cells that are working together.

5. Organs
Organs: a group of tissues that work together to perform a single function or a group of functions.

6. Organ Systems
Organ Systems: A group of organs that perform closely related functions.

7. Tissues
Epithelial
Connective
Nervous
Muscle

8. Epithelial Tissue
Lines the inside and outside surfaces of different organs.
Function(fxn): Protection, absorption, and excretion
Example: Skin, stomach lining.

9. Connective Tissue Provides support for the body and its parts
Bind epithelial tissue to structures, support, and transport.
Examples: collagen,

10. Nervous Tissue Receives and transmits nerve impulses (signals)
Example: Brain, spinal column, and nerves.

11. Muscle Tissue Voluntary and Involuntary movements
Skeletal, cardiac, and smooth muscles.

12. Name the organ without all types of tissue.

13. Organ Systems that work Together

14. Homeostasis Homeostasis:
The relatively constant internal physical and chemical conditions that organisms maintain despite changes in their environment

15. Examples of Homeostasis
Blood pressure
Body Temperature
Blood pH

16. Feedback Inhibition The way the body maintains homeostasis.
The body produces a response to oppose the original stimulus
Heater Example: the heater shuts off after the temp reaches a certain level.
