Skeletal & Muscular System. Function:. The skeletal system …. Holds the body up (structure and shape) Protects internal organs Helps the body move Stores minerals, Calcium, Phosphorus Makes blood cells. PART 1: BONES. -make up the skeletal system Made of living cells and protein fibers
E N D
Function: • The skeletal system …. • Holds the body up (structure and shape) • Protects internal organs • Helps the body move • Stores minerals, Calcium, Phosphorus • Makes blood cells
PART 1: BONES • -make up the skeletal system • Made of living cells and protein fibers • - Produce blood cells in the bone marrow • - 206 bones in adult body • - 300 bones in infant (later fuse together)
PART 2: CARTILAGE • - Softer and more flexible than bone • - gives shape • Connects the bones • Supports the body
Do Now! What are 3 things you learned from the muscle lab? EXPLAIN how proof (DATA) from a lab station led you to learn this?
PART 3: LIGAMENTS • Connects bone to bone • holds bones together at the joints • 900 ligaments in human body
PART 4: JOINTS • where 2 or more bones connect together • Allow movement
PART 5: TENDONS • tough connective tissue that • connects bone to muscle
Muscular System Function The muscular system… -helps you move -helps move blood through the body (arteries/veins/capillaries) -pumps your blood (heart) -helps you breathe (lungs) -moves food through digestive system (stomach, intestines)
TYPES OF MUSCLE • Smooth Muscle • tissue in walls of organs, arteries, veins • In the stomach, lungs, and other soft internal organs • Involuntary movement (moves by itself) • Controls the way blood flows through circulatory system
TYPES OF MUSCLE • Skeletal or Striated Muscle: • attached to legs, arms, back, and torso • Helps to move bones • Voluntary movement
TYPES OF MUSCLE • Cardiac Muscle: • - only in the heart • involuntary movement (moves by itself)
CONNECTION TO THE SYSTEMS • Skeletal and muscular system work together to help you move • Muscular system works with circulatory system to pump blood through the body • Muscular system works with digestive system to move food through digestion • Muscular system works with respiratory system to exchange gases • Muscular system works with excretory system to eliminate waste • Nervous system controls skeletal and muscular system
