Unit 1: Introduction

1
Unit 1 Introduction

• The organization of the human body

2
Anatomy and Physiology

• Anatomy Structure
• Physiology Function

3
5 Levels of Organization

• 1. Cells
• 2. Tissues
• 3. Organs
• 4. Organ Systems
• 5. Organisms

4
How do you know something is alive?

• It needs energy
• It responds
• It moves
• It grows
• It differentiates
• It reproduces

5
Homeostasis

• Homeostasis is a condition of equilibrium or
  balance in the body
• Disruption of homeostasis can lead to disorders,
  diseases, or death.
• Aging is the result of the body being unable to
  maintain homeostasis as effectively over time.

6
Anatomical Position

• Standing upright
• Facing forward
• Feet flat
• Arms at the sides
• Palms forward

7
Directional Terms

• Superior towards the head
• Inferior away from the head
• Dorsal at the back
• Ventral at the front
• Medial towards the midline
• Lateral away from the midline

8
Tissues

• Tissues are groups of cells with a similar
  function
• Histology is the study of tissues
• Pathologists are physicians who specialize in
  studying diseases of tissues

9
4 Types of Tissue

• 1. Epithelial
• 2. Connective
• 3. Muscle
• 4. Nervous

10
Epithelial Tissue

• Epithelial tissue covers body surfaces, lines
  hollow organs and body cavities, forms glands
• Example skin
• Its the easiest to repair and replace

11
Connective Tissue

• Connective Tissue protects and supports the body
  and its organs, holds organs together, and stores
  fat
• Example bone, cartilage

12
Muscle Tissue

• Muscle tissue is responsible for movement and the
  generation of force
• Example heart

13
Nervous Tissue

• Nervous tissue creates and sends signals
  throughout the body
• Example brain, spinal cord
• Its the hardest to repair/replace

14
Diseases and Disorders

• Please research the following diseases and
  disorders of tissues. In your notebooks, record
• the name of the disease,
• the cause,
• susceptibility (who is most likely to get it)
• the symptoms,
• the treatment/cure,
• and the consequences or prognosis.

• Diseases/Disorders
• Cancer
• Sjogrens Syndrome
• Lupus
• General Effects of Aging on Tissues

15
Introductory Project PromptGroups of 1-4

• Using 3D or 2D art as your media, each group will
  be assigned a body system, and will create a
  project that includes the following
• The anatomy of the system (structure)
• The physiology of the system (function)
• The role it plays in maintaining homeostasis
• Each group will also submit a written component
  (3 paragraphs) explaining how your project
  addresses each component above. Due Tues/Weds
  9/22 or 9/23
