Anatomy
The study of structure
Asks what something is, where it is located, and what it does
Physiology
Examines function, seeking to understand how something works
Structural Hierarchy
1) Organism (the complete, living thing)
2) Systems
3) Organs
4) Tissues
5) Cells
* OSOTC
System

Integumentary System
The largest system that forms a physical barrier from the outside world.
Includes the epidermis, dermis, hypodermis, associated glands, hair, and nails.
- protection
- Sensation
- Thermoregulation
- Vitamin D synthesis
Muscular System
- movement
- Stability
- Internal storage
- Heat
- Glucose regulation
Skeletal System
- Protection
- Movement
- Framework/support
- Ca+ storage
- Hematopoiesis
Circulatory System
- Transport
- Immunity
- Regulation
Respiratory System
- Gas Exchange
- Acid/Base balance
- Speech
- Smell
- Blood flow
Nervous System
- Surveillance
- Communication
- Regulation
Digestive System
1) Ingestion
2) Fragmentation
3) Deglutition
4) Digestion
5) Absorption
6) Compaction
7) Elimition
Lymphatic System
- Immunity
- Fat transport
- Drain/recover excess fluid
Urinary System
- Regulate blood volume
- Metabolic waste removal
- Blood pressure regulation
- Acid/base balance
Endocrine System
Hormones
1) Communication
2) Regulation
Reproductive System
Two Types
Reproduce
Organ
Aggregate of tissues performing a specific function
Tissue
Group of cells performing a specific function
4 Types of tissue
Epithelium Tissue
General Function: Covering, lining, barrier
- always in contact with free space
- Cells lie on top of a basement membrane
- Does not have a blood supply
- all nutrients must pass through the basement membrane, if the cells break contact with the basement membrane, they will die.
- Epithelium acts as a barrier keeping the outside out and inside in
- Classified by depth (simple and stratified) and shape (squamous, cuboidal, columnar)
- Rule Breakers: Pseudostratified and transitional
Simple Epithelium
Only one layer
Stratified Epithelium
More than one layer
Squamous Epithelium
Flat cells
Cuboidal Epithelium
Cube-like cells
Columnar Epithelium
Tall cells
Connective tissue
General Function: connective, support, padding Components: 1) Ground Substance 2) Protein Fibers 3) Cells
