Chapter 1 - Introduction to Anatomy and Physiology

Anatomy

study of body structures

Physiology

study of organ functions

Gross Anatomy

examines large, visible structures by eyes

Surface Anatomy

studies exterior features

Regional Anatomy

studies body areas

Sectional Anatomy

studies cross sections

Systemic Anatomy

examines organ system structures

Clinical Anatomy

delves in medical specialties

Microscopic Anatomy

examines cells and molecules

Cytology

study of cells

Histology

study of tissues

Cell Physiology

studies cell functions

Organ Physiology

studies functions of specific organs

Systemic Physiology

studies organ system functions

Pathological Physiology

studies how diseases effect organs/systems

Characteristics of Living Things

Organization

all organisms have a complex structure and order

Characteristics of Living Things

Metabolism

chemical reactions within body

Characteristics of Living Things

Metabolism- anabolism & catabolism

anabolism: small molecules → larger ones

catabolism: large molecules → smaller ones

Homeostasis

maintaining body structure/function using organ systems

What are the Characteristics of Living Things?

Organization, Metabolism, Growth and Development, Reproduction, Responsiveness, Regulation, Evolution

Levels of Organization in Human Body (from lowest to highest)

Chemical Level, Cellular Level, Tissue Level, Organ Level, Organ System Level, Organism Level

Organ System

group of/several organs working together to perform complex function

What are the different planes? (left to right)

Frontal, Sagittal, Transverse
