3 Types of Epithelium tissue - Answer Cutaneous- Dry
Mucous- Wet
Serous- Wet
Cutaneous - Answer Dry, protects the body (skin)
Mucous - Answer Wet, line the bodies cavities that opens to the exterior and most secret
mucous

protects the outside of the organ. Secretes serous, lubricating fluid and also lines the inside of
blood vessels. Lines lungs and heart also.
Functions of the epithelium - Answer Protect the body (skin)
Absorption (digestive tract)
Filtration (kidneys to make urine)
Excretion (kidneys to release urine)
Secretion (exocrine/endocrine glands)
Sensation (skin)

Location: Lungs and the kidneys
Simple cuboidal - Answer Function: secretion and absorption
Location: Kidney tubules, small glands, ovaries
Simple columnar - Answer Function: secretion
Location: GI tract (stomach, small intestine, large intestine)
Pseudostratified columnar - Answer Function: secretion
Location: Trachea
Stratified squamous - Answer Function: protection from abrasion
Location: Skin, mouth, esophagus

Function of cartilage - Answer cushion and support body structures
Hyaline - Answer Provide support with flexibility and resilience.
-Most abundant skeletal cartilage.
Location: Connects ribs to the sternum, in the tip of the nose and lines the trachea.
Types of hyaline cartilage - Answer Articular: cover ends of most bones at moveable joints.
Coastal: connects the ribs to the sternum
Respiratory: for the skeleton of the larynx and reinforce other respiratory passageways.
Nasal: support the external nose
Bone - Answer Function: support
Osteoblast= make new bone
Osteocytes= monitor the bone
Fibrocartilage - Answer Less firm than the hyaline cartilage. Withstand a lot of pressure and
absorb shock.
Location: between each vertebra to absorb shock ; in the menisci of the knee.
Elastic - Answer Made to stretch and bend
Chondroblast (immature) make new cartilage
Chondrocytes (mature) monitor the cartilage
