1. 2. Thoracic and Abdominal Pelvic Membranes
Thoracic membranes:
Walls of right and left compartments are lined with parietal pleura (“pariet” = wall; “pleur” = rib)
Lungs are covered with visceral pleura (“viscera” = organs in a body cavity)
Pleural cavity – fluid-filled “space” between the parietal and visceral pleural membranes
Heart is surrounded by pericardial membranes (“peri” = around; “cardi” = heart)
Visceral pericardium
Parietal pericardium
Pericardial cavity
What do you think the last 3 terms on this slide refer to specifically ?
Label the body cavities and membranes on the handouts provided. Use different colored pencil for each body cavity. (Answers on the following three slides)

5. 3. Organ Systems a. Body covering - Integumentary System
b. Support and Movement:
Skeletal System – support
Muscular System - movement
c. Integration and Coordination:
Nervous System – brain, spinal cord, nerves, and sensory organs
Endocrine System - all the glands that secrete hormones
What do we commonly call the integumentary system?

6. 3. Organ Systems (cont.) d. Transport: e. Absorption and Excretion:
Cardiovascular System – flow of blood
Lymphatic System – transports tissue fluid back to the bloodstream
e. Absorption and Excretion:
Digestive System – receives, breaks down, and absorbs food
Respiratory System – moves air in and out, and exchanges gases between blood and the air
Urinary System – removes waste from blood; maintains water and electrolyte balance
f. Reproductive System – produces offspring

7. Anatomical Terminology
Describes:
Relative Positions of body parts to each other
Body Sections – cutting or sectioning the body along various planes
Body Regions

8. Relative Positions Superior – above (or closer to the head)
Inferior – below (closer to the feet)
Anterior (ventral) – toward the front
Posterior (dorsal) – toward the back
Medial – middle (closer to the R-L midline)
Lateral – side (further from the R-L midline)
Proximal – closer to a point of attachment
Distal – further from a point of attachment
Superficial – near the surface (shallow)
Deep – more internal (further from the surface)
Use the following two slides to quiz positions. Example: The pelvic cavity is inferior to the lungs. (Use other examples for proximal/distal and superficial/deep.)
