Muscular System Functions | • Movement • Heat production |
Muscular System Organs | Smooth Muscle- In digestive tract and blood vessels Cardiac muscle- In heart Skeletal muscle- Attached to bone for movement Connective tissue- •Tendons~ connect muscle to bone •Ligaments~ Connect bone to bone |
What happens in Muscular System | Muscles exert forces in pairs (flexors and extensors) to make the skeleton move |
Muscular & Skeletal | Muscles move skeleton |
Flexor & Extensor | F- Contract to bend joint E- Contract to straighten joint |
Skeletal System Functions | Protection of organs • Storage of minerals • Movement • Blood cell formation |
Skeletal & Muscular | Muscles move the skeleton |
Skeletal & Circulatory | bone marrow Makes red blood cells. |
Skeletal Organs | Bones- are living organs made up of many tissues Bone Marrow- produces red and white blood cells and platelets Joints- where two bones meet Ligaments- connective tissue holding bone to bone |
Circulatory System Functions | • delivers oxygen and nutrients to the bodys celss and takes cell waste away |
Circulatory System Organs | Heart, Blood, Blood Vessels |
Blood Components | Plasma RBC WBC Platelets |
Blood Vessel Components | Arteries Capillaries Veins |
Circulatory & Respiratory | • lungs give oxygen to the bloodstream and the blood takes it to the cells ! • blood takes carbon dioxide from cells and brings to lungs to be released |
