Warm – up 8/18-19/2015
Essentials: stem cell research rubric.Warm-Up: Sit with your group for the debate. You will have 20 minutes to collaborate with each other. AgendaDOL: Scholars will be able to understand ethically debates around stem cell research and identify tissue types. Homework: continue reading Chap. 5, Connective tissue IP, Debate reflection essay (1pg. Double spaced, pen)Announcements:Reflection due and Lab on Thurs/FriConnective Tissue IP due MondayTest August 28th
Slide2HeLa Cells
https://www.youtube.com/watch?v=y38pgPY6Zq0A HeLa cell (also Hela or hela cell) is a cell type in an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line.The line was derived from cervical cancer cells taken from Henrietta Lacks, a patient who eventually died of her cancer on October 4, 1951. Article on Henrietta Lacks

Slide4Rules of Debate
Timer set for 30 minutesCounts as a quiz grade!Review rubric!
Slide5Debate Reflection
For homework tonight, I want you to write a reflection paper of our debate.Your responses must be thoughtful and reflectiveIB Traits: REFLECTIVE, COMMUNICATOR
Slide64 types of tissues
1. epithelial tissue2. connective tissue3. muscle tissue4. nervous tissue
Slide7Epithelial tissue includes…
1. layers of cells that cover internal or external surfaces2. glands
Slide8Some important characteristics are…
1. cells are close together2. a free surface exposed to environment or internal chamber/passageway.3. attachment to basement membrane provides barrier4. no blood vessels (avascular)5. continually replaced and regenerated
Slide9Functions of epithelia…
1. Provide physical protection2. Control permeabilityWhat comes in and out3. provide sensation4. produce specialized secretionsExocrine= secretions released to surface of skinEndocrine= secretions released as hormones into tissue fluid & blood
Slide10Warm – up 8/20-21/2015
Essentials: Epithelial Chart, Cheek cell lab, exit ticket slip Warm-Up: Turn in your reflective essay (staple to rubric)Label the tissue types (Tissues IP) AgendaDOL: Scholars will be able to identify epithelial and tissue types by cell structures.Lab: Cheek cells and epithelial layersHomework: Tissue PosterReading Chap. 5, Connective tissue IPAnnouncements:Quiz M

Slide11Epithelial cells are classified by amount of layers and shape…
Simple = one layerstratified = multiple layersPseudostratified = looks like multiple layersSquamous = thin/flatCuboidal = shaped like a cube or hexagon (6)Columnar = long and skinnyCiliated = contain ciliaLAYERSSHAPE
Slide12An example…
One layer with tall and skinny cells Simple columnarMulti-layered and square shapedStratified cuboidal
Slide13Pseudostratified Ciliated Columnar
Location: respiratory tract (nasal cavity, larynx, trachea, bronchi)Function: cilia moves mucus across the surface of the cells, protection
Slide14Glands
Endocrine glands – secrete hormones directly into the bloodstreamHormones are chemical messengers that influence cells in the rest of the bodyExocrine glands – use different processes to release secretionsEx: sweat glands, mammary glands, salivary glands
Slide15The purposes of Connective Tissue…
Bind (hold things together)Support & protectFill spacesStore fatProduce blood cells
Slide16Locations: Widely distributed throughout the body
Facts:Good blood supplyFarther apart than epithelial cellsConnected with matrix
Slide17Exit Tickets
1. a single layer of cells that are thin and flat are called:2. a multi-layered group of cells that are long and skinny are:3. a single layer of square cells4. What connective tissue is responsible for storage of energy?SHOUT OUTS!

Essentials: Types of epithelial tissue, sheet of legal paper, quiz sheet, Tissue review packet (1per table) CLASS SET!Warm-Up: At your table review types of tissues and their function. 5 minutesQUIZ TODAY!AgendaDOL: Scholars will be able identify tissue types and relate its structure to function by location.Homework: Tissues posters (quiz grade)Announcements:Test August 28

Slide19Classification of Connective Tissue
Connective tissue properLoose connective tissueAreolarAdiposeReticular Dense connective tissueSupporting connective tissueCartilageBone Fluid connective tissueBlood
Slide201.a. Loose Connective Tissue
lies under skin, connect it to organs, provides blood supplyThe body’s “packing material”
Slide211.a.i. Areolar
Function: Protects tissues and organs, binds epithelia to deeper tissueLocation: dermis (skin)
Slide221.a.ii. Adipose
Function: stores energy, insulates & cushionsLocation: subcutaneous layer (deep to skin), surrounding organs
Slide231.a.iii. Reticular
Function: provides support to lymphatic system organsLocation: spleen, lymph nodes, thymus, bone marrow
Slide241.b. Dense Connective Tissue
very STRONG, used to bind parts togetherFunction: attaches bone to bone (ligaments), muscle to bone (tendon)Location: ligaments, tendons
Slide251.b. Dense Connective Tissue
LigamentsConnects BONE to BONETendonsConnect MUSCLES to bone
Slide262.a. Cartilage
Function: Protects, absorbs shock (in joints)Location: tip of nose, ends of long bones, intervertebral discs, external ear
Slide272.b. Bone
very rigid, heals quicker than cartilageFunction: provides support (more than cartilage) and levers for movementLocation: bones of the body
Slide283.a. Blood
Function: helps transport and maintain internal environmentLocation: blood vessels, heart
Slide29Tissue Rotations and Cheek cell Lab
Slide30Station Expectations
One group at each station2 min at each stationRotate clockwise
Slide31Tissue Posters
Four types of tissueLocation of tissuePurpose/function of each tissueClassification of tissueMemory Device (How you will remember each type)Drawing of each type of tissueCreativity/colorNeatnessThis will count as a quiz grade!
