Anatomy and Physiology Notes — Transcript Summary

Introduction to Anatomy and Physiology

  • Anatomy - Structure

  • Physiology - function

  • Function always reflects Structure

  • Structural level of organization:
    atom → molecule → cell → tissue → organ → organ system → organism

Body Systems Overview

  • Integumentary - body coverings, protection, skin

  • Skeletal - Support, protection, bones

  • Muscular - Movement (Sketetal, cardiac, smooth)

  • Nervous - Control, brain & spinal chord

  • Endocrine- regulation, glands secrete hormones

  • Cardiovascular - transport, heart and blood vessels

  • Lymphatic/Immune - protection, fight pathogens

  • Urinary- remove wastes, kidneys + bladder

  • Respiratory - take in oxygen and remove CO₂

    • lungs

  • Digestive - break down food, stomach &intestines

  • Reproductive - produce offspring

Methods of studying Anatomy

  • gross anatomy - study of large body structures

  • cytology; histology

  • Microscopic anatomy - study of body's cells and tissues

  • Systemic anatomy - gross anatomy is studied by system

  • regional anatomy - all structures in a region are studied

Important Tools for Studying Anatomy

  1. Observation

  2. Manipulation

  3. Mastery of anatomical terms
