19. Blood Tissue Blood does not connect anything or give support, but develops from a mesenchyme , consists of cells, and contains a matrix Contains either red or white blood cells Fibers are made of a soluble protein molecules that form clots Functions include being the transport vehicle for the cardiovascular system, carrying nutrients, wastes, and respitory gases, and other substances throughout the body. Connective Tissue

20. Bone Tissue Bone tissues support and protect body structures Bone matrix is similar to cartilage matrix, but is harder and more rigid Contains osteoblasts, which produce the organic part of the matrix Contains osteons which are formed by rings of bony matrix Connective Tissue

21. Cartilage Tissue Cartilage can withstand both tension and compression Tough and flexible Lacks nerve fibers, and recieves nutrients via diffusion by blood vessels Contains chondroblasts which produce new matrix until the end of adolesence Hyaline Cartilage Elastic Cartilage Fibrocartilage Connective Tissue

22. Hyaline Cartilage The most abundant cartilage in the body Provides support with a bit of pliability Found on the end of articular cartilage, the end of the nose, connects the ribs to the sternum, and supports the respitory passages Most hyaline cartilage is formed in the embryonic skeleton Cartilage Tissue Elastic Tissue Fibrocartilage

23. Elastic Tissue Nearly identical to hyaline cartilage, but contains more elastin fibers Found where strength and and stretchibility are a must Forms the ear and the epiglottis Hyaline Cartilage Fibrocartilage Cartilage Tissue

24. Fibrocartilage Fibrocartilage is a balance between both hyaline cartilage and elastic cartilage Found where strong support and the bility to withstand pressure is required, like intervertebral discs and the cartilage of the knee Hyaline Cartilage Elastic Cartilage Cartilage Tissue

25. Connective Tissue Proper Contains two subclasses- Dense Connective and Loose connective Connective Tissue Reticular Adiopose Areolar Regular Dense Irregular Dense

26. Recticular Connective Tissue Resembles Areolar connective tissue Fibers in this tissue are reticular fibers, which contain reticular cells in their network Forms a labryinth like stroma that supports free blood cells in the lymph nodes, spleen, and bone marrow Adiopose Areolar Regular Dense Irregular Dense

27. Adiopose Connective Tissue Similar to areolar tissue Store much more energy than Areolar Connective tissue Contain adiocytes and is very vascularized Constitutes 18% of a persons body weight Can develop almost anywhere, which some organs need to keep working Also referred to as white adiopose tissue to distinguish it from brown adiopose tissue Connective Tissue Proper Areolar Dense Regular Dense Irregular

28. Areolar Connective Tissue Functions include supporting and binding other tissues, holding body fluids, defending against infection, and storing nutrients The most widely distributed connective tissue throughout the body Adopose Reticular Dense Regular Dense Irregular Connective Proper

29. Regular Dense Connective Mainly made up of fiber, which run in the same direction.This gives a great resistance to tension Contains fibroblasts that make the fibers Form the tendons and aponeuroses and the fascia Adopose Areolar Reticular Irregular Dense Connective Tissue Proper

30. Irregular Dense Connective Tissue Has the same makeup as the regular variety, but the collagen fibers are arranged differently and the fibers are thicker Forms where tension is exerted in more than one direction. Found in the dermis, and the fibrous coverings of some organs Connective Proper Adopose Areolar Reticular Dense Regular Dense Irregular
