The Systems of the Human Bodypp. 16 - 17

Transport.

Breaks down nutrients. Produces hormones that regulate cell functions.

Systems of the Human Body

Skin Defenses Movement

Systems of the Human Body

Monitors and maintains our internal environment Exchanges oxygen and

carbon dioxide with blood.

Systems of the Human Body

Removes toxins and excess molecules from blood.

Day 3 Begins Here

Bone Structure• Structurally, bone is classified into 2 types:• 1) Spongy Bone (pg. 191) Note the trabeculae.

Bone Structure• 2) Compact bone • pp. 191.• Note: we will discuss

the microscopic structure of bone in the next unit.

Bones are divided into 4 basic shapes pg. 184

1: Long Bones (pg. 186)• Longer than wide• Cylinder shaped.• Located in the appendicular

skeleton. • Diaphysis (compact)• Epiphysis (spongy)

Long Bone

• Medullary Canal• Yellow marrow• Periosteum

2: Short Bones• Cube-like.• Filled with spongy bone, with a thin layer of compact covering it.• No hollow medullary canal present.

3. Flat Bone• Thin, flat.• Spongy bone interior (diploe),

compact bone exterior.

4. Irregular Bone

• Usually described as a cross between a flat bone and a short bone.

• Spongy interior. • Vertebrae and some skull bones would be

examples.
