HUMAN ORGAN SYSTEM - Coggle Diagram

- - - - Excitable or Irritable: Muscles are Excitable or Irritable. This means that they are capable of receiving stimulation and responding to stimulation from the nerves.
      - Contractible: They are contractible. After receiving stimulation, they are capable of contracting, or shortening.
      - Extensible: Being extensible means a muscle can be stretched without damage by the application of force.
      - Elasticity: With elasticity, a muscle is able to return to its original resting shape and length after being extended or contracted.
      - Adaptability: The muscular system is adaptable in that it can be changed in response to how it is used. For example, a muscle will enlarge, or undergo hypertrophy with increased work; but on the other hand it can go in atrophy, or waste away if deprived of work.
    - - Adduction movement of the muscle toward the body
      - Flexion means bending a joint to decrease the angle between two bones or two body parts.
      - Extension- extension is straightening and extending of the joint to increase the angle between two bones or body parts.
      - Rotation and last, rotation involves move a body part around an axis.
      - Abduction is the moving of a body part toward the mid-line of the body
    - - Cardiac Muscle (Heart) The cardiac muscle, is an involuntary muscle; meaning it operates without any conscious control.
      - Smooth Muscle (Organ: digestive and respiratory) also considered involuntary – these muscles are found in organs or organs systems such as the digestive or respiratory system.
      - Skeletal muscle (attach to the skeleton)- allows movement These muscles attach to the skeleton and provide the skeleton with the ability to move. The Skeletal Muscles are classified as voluntary. This is because we have to make a conscious effort or decision to make them move.
  - - - Skull=brain
      - Ribs= heart and lungs
      - Vertebrae-spinal cord
      - Femur produces blood cells in the leg
      - Humerus=produces blood cells in the arm
    - - Axial-vertical axis of the body. Foundations of the skeletal system or bones. Provide skeletal support and organ protection. (Skull, Rib cage, Vertebral column)
      - Appendicular. Helps the body to move around
    - - Long bones
        Limb bones: Fibula, tibia, metacarpals
      - Short bones Foot: Talus and cuboid, Wrist: Lacunate or scaphoid
      - Flat Bones Thin bones (Sternum and scapula)
      - Irregular bones Weirdly shaped bones that is specialized and unique
        (Vertebrae and Pelvis)
    - - Red Bone Marrow- Produces blood Vessels
      - Yellow Bone Marrow Stores energy and fat
- - - - Dendrites-takes in the electric messages to cell body
      - Axon- takes away the electric messages away from the cell body
      - Nucleus
- - - - Artery carries oxygenated blood (RED)
      - Veins carries deoxygenated blood (BLUE)
- - - - Alveoli
      - Capillary
      - Bronchiole
