Homework #1 – Tissues
Due 7-6-10
1. Provide the definition of a Tissue .
- Cells organized together, displaying the emergent property of tissue function.
2. Provide the functions of the four major tissue types: a. Epithelium
1) Provide physical protection
2) Controls permeability
3) Provides sensation
4) Produces specialized secretions b. Connective
1) Support and protect
2) Transport materials
3) Storage of energy reserves
4) Defense c. Muscle
1) Contraction d. Nervous
1) Specialized for conduction of electrical impulse transmission from one part of the body to another.
3. Name an organ in which each of the following tissues is found: a. Simple squamous epithelium– Blood vessels, kidney tubules b. Simple cuboidal epithelium– Salivary glands c. Simple columnar epithelium– Stomach lining, excretory ducts d. Pseudostratified columnar epithelium– Trachea, nasal cavity e. Stratified squamous epithelium– Mouth, skin, esophagus f. Stratified cuboidal epithelium– Salivary glands, mammary glands g. Stratified columnar epithelium– Intestines, stomach h. Transitional epithelium– Urinary bladder
4. Explain the function/importance of each of the following tissues in the location
provided (there may be more than one function). a.
Simple sqaumous epithelium in the alveoli of the lungs:
-Protects regions for absorption or to reduce friction b. Ciliated epithelium in the trachea:
-Help secrete and move material c. Stratified squamous epithelium in the espophagus:
-Severe mechanical stress

-Makes it strong and resistant to shattering e. Fibrous connective tissue in ligaments:
-Makes it durable and tough, absorb shock and prevent bone to bone contact
