ORGANIZATION of LIFE FORMS Living Organisms include PLANTS ANIMALS Cannot make their own food Have cell walls Have cell membranes Photosynthesis Herbivores, Carnivores, Omnivores Make their own food Photosynthesis EUKARYOTES Prokaryotes / Bacteria & Viruses

 Human body systems: ◦ All living organisms are cell based ◦ Plants have cell walls & cell membranes, Animals have only cell membranes.  Cells – Tissues – Organs – Organ Systems - Organisms smallestlargest Now we will look at Tissues, Organs and Organ Systems

1.Skeletal 2.Muscular 3.Circulatory 4.Respiratory 5.Digestive 6.Excretory 7.Nervous 8.Endocrine 9.Reproductive 10.Integumentary (skin and connective tissue) 11.Immune

 Functions of the Skeleton: 1.Provide support & protection to the body organs 2.Provides for mobility (movement) as a place for muscles to attach to bones allowing movement. 3.Provides a store place for energy (yellow bone marrow) 4.Provides a machine to produce red blood cells ( red marrow in long bones)

Joints of the Skeleton Pivot Joint – up down, side to side motion Found in: Skull onto vertebrae of the backbone (NECK) Hinge Joint – forward or backward movement Found in: knees, elbows, fingers, toes Gliding Joint – rotation Found in: wrists, ankles Ball & Socket Joint – up, down, rotation Found in: shoulder, arm (humerus into scapula) leg, hip (femur into pelvis) PAGE 436 / Text

Functions of Muscles MOBILITY of the body FORCE PUMP for blood DIGESTION of food Different Types of Muscle Tissue: 1. CARDIAC – Heart only involuntary control 2. SKELETAL – muscles attached to the skeleton voluntary control 3. SMOOTH – hollow visceral organs like the stomach and intestines, involuntary control

Involuntary Voluntary Muscle diagrams and Actual slides HEART muscle Also called Cardiac muscle Stomach, intestines

Muscle Diagrams and Labeling 1.) Go to the Muscle Website: djigsaw_02/index.shtml?muscles 2.) Visit the website, play with location of the muscles 3.) Go to the bottom of the frame and click onto the Muscles work in pairs. Read the information, take notes in your spiral on the key topics. Draw pictures if they help you remember key ideas. 4.) Click onto the link on the right: muscle anatomy diagram / front 5.) Label your muscle diagram handout.
