• 2 is nervous tissue

  
• 3 is skeletal muscle

  
• 1 is cytoplasm

  2 is nucleus

  3 is plasma membrane

  
• 1 is nucleus of simple squamous epithelial cell in visceral layer of pleura

  2 is simple squamous epithelium

  3 is connective tissue

  4 is nucleus of simple squamous epithelial cell in alveolar wall

  
• You can find it in the internal lining of heart and blood vessels or the internal lining of ventral body cavities, such as the pericardium, pleura or peritoneum. It allows active and passive movement of substances.

  
• 2  Apical surface of simple cuboidal epithelial cell

  3  Lumen of kidney tubule

  4 Nucleus of simple cuboidal epithelial cell

  1  Simple cuboidal epithelium

  
• You can find it in the ovaries and thyroid. One function is secretion and absorption

  
• _4__  Connective tissue

  _1__  Microvilli on apical surface of simple columnar epithelial cell

  _2__  Nucleus of simple columnar epithelial cell

  _3__  Simple columnar epithelium

  
• You can find it in the lining of the intestine. One function is to move mucous and other substances

  
• _4__  Connective tissue

  _3__  Nucleus of epithelial cell in basal layer of epithelium

  _1__  Nucleus of squamous epithelial cell

  _2__  Stratified squamous epithelium

  
• You can find it in the epidermis or mouth, sophagus, larynx, vagina and anal canal. It prevents water loss.

  
• _4__  Connective tissue

  _1__  Nucleus of transitional epithelial cell in apical layer

  _2__  Nucleus of transitional epithelial cell in basal layer

  _3__  Transitional epithelium

  
• Transitional epithelium can be found in the lining of the kidney, ureters, urinary bladder and part of the urethra. A function of this to change shape depending on the degree of distension of the organ

  
• _2__  Cilia on apical surface of columnar epithelial cell

  _4__  Connective tissue

  _1__  Nucleus of ciliated columnar epithelial cell

  _3__  Pseudostratified ciliated columnar epithelium

  
• You can find pseudostratified ciliated columnar epithelium in the trachea (mostly in the respiratory system). It helps move substances like mucus

  
• _1__  Collagen fiber

  _3__  Connective tissue cells (fibroblasts or lymphocytes)

  2 Elastic fiber

  
• Loose connective tissue can be found in the epithelial linign of the digestive tract, mesentary. Some functions are that it supports microvasculature, nerves and immune defense cells

  
• _2__  Reticulocyte

  _1__  Reticular fiber

  
• Example: bone marrow, liver, pancreas, adrenal glands, all lymphoid organs except the thymus

  Function: Supports blood-forming cells, many secretory cells, and lymphocytes in most lymphoid organs

  
• _2__  Lipid storage area

  _1__  Nucleus of adipocyte

  
• _2__  Collagen fiber bundle

  _1__  Fibroblast

  
• Dense regular connective tissue can be found in ligaments, tendons and aponeuroses. Some functions of the the tissues is to provide strong connections within musculoskeletal system and strong resistance to force

  
• _2__  Collagen fiber bundles running in different directions

  _1__  Fibroblast

  __3_ Parallel collagen fiber bundles

  
• Dense irregular connective tissue can be found in the dermis of the skin, organ capsules, submucose layer of digestive tract. Some function is to protect and support organs and resists tearing

  
• 3 is Bundle of elastic fibers

  1 is Fibroblast

  2 is Individual elastic fiber
