animal tissues - Coggle Diagram

- - - - found below the skin and between internal organs
  - - - Cartilage has widely spaced cells.
      - The solid matrix is composed of proteins and sugars.
      - Cartilage smoothens bone surfaces at joints and is also present in the nose, ear, trachea and larynx.
    - - It forms the framework that supports the body.
      - It also anchors the muscles and supports the main organs of the body.
      - It is a strong and nonflexible tissue.
      - Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds.
  - - - ligament
        
        bone to bone
        
        very little matrix
        
        considerable strength.
        
        elastic
      - tendon
        
        bone to muscle
        
        fibrous tissue
        
        great strength
        
        limited flexibility.
  - - - The spleen, tonsils, adenoids, and the thymus all form a part of the lymphatic system
    - - Blood has a fluid matrix called plasma,
      - RBCs, WBCs and platelets are suspended.
      - The plasma contains proteins, salts and hormones.
      - Blood flows and transports gases, digested food, hormones and waste materials to different parts of the body.
- - - - Where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present.
      - This columnar (meaning ‘pillar-like’) epithelium facilitates movement across the epithelial
    - - These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is thus ciliated columnar epithelium
      - In the respiratory tract, the columnar epithelial tissue also has cilia, which are hair-like projections on the outer surfaces of epithelial cells.
  - - - Skin epithelial cells are arranged in many layers to prevent wear and tear.
      - Since they are arranged in a pattern of layers, the epithelium is called stratified squamous epithelium
    - - Simple squamous epithelial cells are extremely thin and flat and form a delicate lining.
      - The oesophagus and the lining of the mouth are also covered with squamous epithelium.
- - - - striated

        the iris of the eye
        
        ureters
        
        bronchi of the lungs.
    - - Long
      - spindle-shaped
