1. Simple Squamous Epithelium: Function & Location?

   Substances Pass through; air sacs in lungs & walls capillaries and blood vessels

2. Areolar Tissue

   Loose connective tissue binding the skin to underlying organs and filling spaces between muscles.

3. Connective Tissue

   Abundant tissue binding structures, providing support, filling spaces, storing fat, producing blood cells, protecting against infection, and aiding in repair.

4. Epithelial Tissue

   Widespread tissue covering all body surfaces, inside and out, and major tissues of glands.

5. Basement Membrane

   Thin, non-living layer anchoring the underside of epithelium.

6. Diffusion

   Method of nourishing epithelial tissue due to the lack of blood vessels.

7. Microvilli

   Cell surface extensions increasing the surface area of epithelial tissue.

8. Goblet Cells

   Epithelial cells secreting protective mucus.

9. Simple Squamous Epithelium

   Single layer of thin, flattened cells allowing easy substance passage, found in air sacs of lungs and walls of capillaries.

10. Simple Cuboidal Epithelium

    Single layer of cube-shaped cells involved in secretion and absorption, found in ovaries, kidney tubules, and gland ducts.

11. Simple Columnar Epithelium

    Elongated cells providing protection, secreting digestive fluids, and absorbing nutrients, found in the lining of the uterus and digestive organs.

12. Pseudostratified Columnar Epithelium

    Cells appearing layered due to nuclei placement, containing cilia and goblet cells, lining respiratory passages.

13. Stratified Squamous Epithelium

    Consists of many layers of cells, forming the outer layer of the skin and lining the mouth, throat, vagina, and anal cavity.

14. Transitional Epithelium

    Specialized to undergo changes in response to tension, forming the lining of the bladder and urinary system.

15. Extracellular Matrix

    Fibrous intercellular material found between cells in connective tissue.

16. Fibroblast

    Connective tissue cell producing fibers that make up the matrix.

17. Mast Cells

    Connective tissue cells aiding in clotting and inflammation.

18. Macrophage

    Connective tissue cell functioning as scavenger or defense cells to clear foreign particles.

19. Cartilage

    Supportive tissue found in hyaline, elastic, and fibrocartilage types, supporting, protecting, and forming structural models for developing bones.

20. Bone

    Rigid connective tissue providing internal support, protecting vital organs, serving as attachment points for muscles, and forming blood cells.

21. Blood

    Tissue composed of cells suspended in fluid, transporting substances in the body.

22. Skeletal Muscle Tissue

    Voluntary muscle tissue found in muscles attached to bone, controlled by conscious effort, and having striations.

23. Smooth Muscle Tissue

    Involuntary muscle tissue lacking striations, found in the walls of hollow organs and not stimulated by conscious effort.

24. Cardiac Muscle Tissue

    Involuntary muscle tissue present only in the heart, responsible for pumping blood, and having striations with intercalated discs.

25. Nervous Tissue

    Tissue found in the brain, spinal cord, and nerves, composed of neurons sensitive to changes and transmitting impulses.

26. Collagenous Fibers

    Relatively thick, thread-like fibers composed of the protein collagen, providing flexibility and resistance to pulling forces, found in dense connective tissue.

27. Elastic Fibers

    Fibers embedded with elastin, providing flexibility and found in vocal cords, skin, and blood vessels.

28. Glandular Epithelium

    Composed of cells designed to produce and secrete substances, forming glands such as merocrine, apocrine, and holocrine glands.

29. Adipose Tissue

    Fat tissue serving as a protective cushion for joints and organs, an insulator beneath the skin, and an energy store.

30. Dense Connective Tissue

    Tissue containing thick, closely packed fibers that can withstand pulling forces, found in tendons and ligaments.

31. Merocrine Gland

    Fluid cellular products released through cell membrane. Salivary glands, sweat, pancreatic.

32. Apocrine Gland

    Lose small portions of cells during secretion. Mammary glands, ceruminous.

33. Holocrine glands

    Release entire cells filled with secretion products. Sebaceous glands

34. Elastic Cartilage

    Scary One; stretchy

35. Hyaline Cartilage

    Not at stretchy; non-scary
