EpitheliumEpitheliumLines, covers, and protects other tissues
and organs.Characterized by:
Cells tightly junked togetherjunked together Named by:
Cell shapeCell shapeOther characteristics of the cells.
Squamous, Cuboidal, and Columnar

Connective TissueConnective TissueBind structure together, form a framework
and support the organ and body as whole. Characterized by:
Abundance of intracellular matrix with relatively a few cell.

Connective TissueConnective Tissue
Characterized by the cells widely separated from each other in a matrix that is produced by the cells.

Store fat.Transport substance. Protect against disease. help repair tissue damage .

Loose Connective Tissue Loose Connective Tissue (Areolar)(Areolar)
Gel like ground with both elastic and non-elastic fibers running though the ground in many directions.Wraps and cushions organsUnder the skin

Dense Regular Connective Dense Regular Connective TissueTissue
Nuclei and fibers arranged in parallel rows.Tendons and ligamentsFibers mostly non-elastic

Adipose (Fat)Adipose (Fat) Function as storage cells for adipose (lipids) Adipose cells contain a large vacuole which in
the live cell contains lipids. Cell nucleus and cytoplasm are pushed out to
edge of cell membrane.

CartilageCartilage Ground of matrix is gum like. Cells are found in Lacunae within the matrix. Fibers may be elastic or non-elastic, or a form of
non-elastic called reticular(where the non-elastic fibers of very thin)Hyaline CartilageHyaline Cartilage-example on the ends of bonesElastic CartilageElastic Cartilage- example ear cartilageNon-elastic Cartilage- example nose cartilage.

the Haversian canal systems.

Vascular Tissue (Blood)Vascular Tissue (Blood) Liquid matrix = plasma
90% water10%Plasma proteins, electrolytes, hormones, oxygen,
glucose etc. Formed elements
ErythrocytesErythrocytes -48billion(female) to 54 billion (male) cell / ml of blood in humans. Mammals are enucleated while rest of the vertebrates they have nuclei
LeukocytesLeukocytes -about 7.5 million / ml of bloodPlateletsPlatelets -blood clotting
