Chapter 4 – Tissues 4.1 – Epithelial Tissue Tissues ________________________ are made up of _____________________ o __________________ connect with one another via different ___________________________ to form _______________________ ______________________ junctions: _______________ join together _________________ ________________________ Example: cells in the intestine ______________ junctions: _____________________ or “gaps” between cells that allow the ___________________ of molecules Example: calcium moving between cells ________________________ junctions: act like “_________________________” to hold the cells _________________________________ in the tissue Example: skin cells There are 4 ________________________ tissue types 1. ______________________________: covers the __________________ ________________________, lines body cavities and forms _________________________ 2. ______________________________: _______________________ and __________________________ the body 3. ______________________________: generates physical _______________________ needed for ________________ _________________________ 4. ______________________________: detects _________________________ inside and ______________________ the body, ______________________________ body activities Epithelial Tissue Divided into 2 types 1. ________________________ &_____________________ epithelium: Covers the _____________________ ______________________ of the body and __________________ internal organs 2. _______________________________ epithelium: Makes up the _______________________ portion of _____________________ (sweat glands) _______________________ hormones or other products Functions o ___________________________, absorption, __________________________ and secretion Characteristics 1. Epithelial cells are packed __________________________ _____________________ to form ______________________________ ___________________ 2. Epithelial cells have an ______________________ surface and a _____________________ surface _____________________: most ________________________________ layer of cells _____________________: _______________________ layer of cells; between the ___________________________ and the underlying ______________________________ tissue 3. Epithelial cells are ____________________________; they lack __________________ _______________ 4. Can _________________________ easily—cells are ____________________________ ____________________ Covering and Lining Epithelium o Classified according to the _______________________ of _____________________ and the _____________________ of the ____________________ o o Number of Layers: _______________________: _____________ layer _______________________: more than _______________ layer _____________________________________: looks like _________________ layers but it’s only ________________ layer Shape of cells __________________________: _________________________ __________________________: ___________________ - ___________________ __________________________: _________________________-_____________ o _________________________ Epithelium 1. __________________________ _____________________________ _____________________ layer of __________________ cells Found in the _________ ____________ of ________________ and _________________ of the __________________ and blood vessels Allow material to pass through by ______________________ and ____________________ ___________________________ lubricating substances 2. ____________________________ _____________________________ ___________________ layer of flat ________________-shaped cells Found in the ________________ and ________________________ portions of small ____________________ and in kidney tubules ________________________ and _____________________ 3. __________________________ __________________________ ______________________ layer of tall/______________________ like cells Ciliated Tissues: found in _____________________, uterine tubes and the _____________________ Smooth(unciliated tissues): found in the ________________________ tract, _________________________ _________________________ and ______________________ mucous and _______________________ 4. _________________________________________ _____________________ layer of cells, some are _______________________ than other Often looks like a ___________________________ layer Lines the _________________________ and the upper ___________________________ tract _________________________ mucus, and moves mucus o ___________________________ Epithelium 1. ____________________________ ___________________________ ______________________ layers of _________________ ________________________ Lines the ___________________________, ______________________ and vagina ________________________ against ________________________ 2. _______________________________ cuboidal Rare Function is mainly ___________________________, secretion and _________________________ 3. Stratified ______________________________ ________________________ Function is protection and secretion 4. _______________________________ Epithelium _________________________ of cells depends upon the amount of _________________________________ Lines the ____________________________, urethra and the _____________________ Allows the __________________________ organs to ________________________ and _____________________________ _________________________________ Epithelium o Function is to __________________________ ______________________, hormones, ______________, ______________________, earwax, saliva and mucus o Two Major glandular epithelium gland types __________________________ gland: secretes _____________________________ ____________________ into the ______________________________________ Example: thyroid gland secretes the hormone thyroxin into the bloodstream and is distributed throughout the body raising metabolism _________________________ gland: secretes their substances into _________________ which carry the secretions to the ___________________________ surface Example: sweat glands, saliva and mammary glands Name: ______________________________ Period: _______________ Chapter 4.1: Epithelial Tissue Check for understandings must be turned in at the end of the PowerPoint in order to receive credit Check for Understanding 1 1. _______________________________ 2. _______________________________ 3. _______________________________ 4. _______________________________ 5. _______________________________ 6. _______________________________ 7. ___________________________________________________________________________________________ ___________________________________________________________________________________________ Check for Understanding 2 1. _____________________________________________ 2. _____________________________________________ 3. _____________________________________________ 4. _____________________________________________ 5. _____________________________________________ 6. _____________________________________________ Crash Course: Tissues Part 2-Epithelial Tissue 1. covers and lines your outer and inner body: ___________________________________________ 2. forms your glands and secretes hormones: ____________________________________________ 3. From where does epithelial tissue receive blood: ___________________________________________ 4. What are the 3 basic cell shapes and draw an example of each along with a description of each (obviously you can do this after the video) USE THE BACK OF THIS SHEET 5. cell shape where things like transportation, absorption, diffusion is important:____________________________ 6. cells shape found in the stomach lining: _____________________________________ 7. where would you find the most squamous cells: _________________________________ 8. What are the 3 basic cell layers and draw an example of each along with a description of each (obviously you can do this after the video) USE THE BACK OF THIS SHEET 9. What would be a cells first name and a cells last name (you can provide an example instead if easier) a. First name:___________________________ Last name: __________________________ 10. the outer surface of the epithelial tissue: _______________________________ 11. the inner surface of the epithelial tissue which anchors the epithelial tissue to the connective tissue below: ____________________________________ 12. secrete hormones directly into the bloodstream and into nearby cells: __________________________ 13. secrete into tubes or ducts that lead to outside of the body____________________________
