Presentation Transcript

  1. Epithelial Cells form Epithelial Tissue • Structure: • Epithelial Cells pack tightly together and form continuous sheets that line different parts of the body. • Function: • Protection, secretion, absorption, and transport • Examples: • Inside the mouth (cheek cells) • Line organs like the stomach • Surround the outside of organs • Make the outer layer of skin

  2. MUSCLE TISSUE • Structure: • Muscle cells make specialized tissue that can contract. • Muscle tissue contains the specialized proteins actinand myosin that slide past one another. • Function: • Allows for movement of limbs and contraction. • Examples: • Heart – Cardiac Muscle • Body Movement—Skeletal Muscle • Digestive Tract, Veins/Arteries, Bladder—SmoothMuscle

  3. NERVE TISSUE • Structure: • Elongated cells with many branches. • Function: • Has the ability to generate and conduct electrical signals in the body. • These signals are managed by the brain and transmitted down the spinal cord to the body.

  4. White Blood Cell • Structure: • Large, flexible cells • Covered in proteins that recognize invaders. • Function: • Part of your immune system. • Fight off bacteria and other invaders. • Examples: • Neutrophils – engulf bacteria • Basophil – Release histamine to promote and inflammatory response.

  5. Red Blood Cell • Structure: • Round, disc-shaped cell • Concave center • Function: • Transport oxygen throughout the body.

  6. Plant Leaf vs. Plant Stem • Leaf • Contains Guard Cells that open and close to allow for gas exchange • Lined with Chloroplasts • Stem • Contain Xylem and Phloem that carry food and water up the stem of the plant.
