2 Distinguish between the functions of red marrow and yellow marrow.
Sponge: Set up Cornell Notes on pg. 59 Topic: 7.1 Functions of bone Essential Question: Distinguish between the functions of red marrow and yellow marrow. 7.1 Functions of Bone 2.1 Atoms, Ions, and Molecules Distinguish between the functions of red marrow and yellow marrow.

3 On pg. 59 Tree Map of functions of bone
Skeletal System: Functions of Bone Support, Protection, Movement Blood cell formation Inorganic Salt Storage

4 Skeletal System Bones may appear to be non-living, but bone contains very active, living tissues Bone tissue Cartilage Dense connective tissue Blood Nervous tissue

5 Bone Function Support and protect softer tissues
Provide points of attachment for muscles Aid in body movement House blood-producing cells Store inorganic salts

6 Support, Protection, and Movement
Give shape to head, face, thorax, and limbs Bones of lower limbs, pelvis, and vertebral column support the body’s weight Skull protects eyes, ears, and brain Ribs cage protects heart and lungs Pelvic girdle protects reproductive organs

7 Blood cell formation Hematopoiesis: process of blood cell formation
Happens in bone marrow (soft, connective tissue) Red marrow: forms RBC, WBC, and platelets Yellow marrow: stores fat and is inactive in blood cell production In cases of severe blood loss, the body can convert yellow marrow back to red marrow to increase blood cell production.

8 Inorganic Salt Storage
The salts account for 70% of the extracellular matrix of bone tissue by weight Body requires calcium for blood clot formation Osteoporosis- loss of bone mass and mineral content Bones develop spaces and canals Enlarge and fill with fatty tissue No longer able to support body weight Easily fracture Associated with aging

9 Clinical Application 7.2: Osteoporosis
Pg. 58 Clinical Application 7.2: Osteoporosis Please read and highlight 7.2 Clinical App as well as answer the following 5 questions. What is osteoporosis? What happens to affected bones? Who is most at risk for a hip fracture due to osteoporosis? Name 5 factors increase the risk of osteoporosis? What are 3 ways to prevent osteoporosis?
