Connective Tissue Flashcards
(17 cards)
connective tissue
most abundant tissue in the body
function of connective tissue
support, protection, transportation
two main elements of connective tissue
extracellular matrix and cells
two main elements of extracellular matrix
ground substance and fibres
what cells give rise to connective tissue
mesenchymal cells
immature “blast” cells
produce the fibre in extracellular matrix
process of cells becoming specialised
mesenchyme -> blast cell -> type of tissue
cells found in connective tissue
fibroblasts, adipocytes, macrophages
various structures of ground substance
fluid, semi fluid, gelatinous, calcified
three fibres found in extracellular matrix
collagen fibres, elastic fibres, reticular fibres
loose / areolar tissue
functions in strength, elasticity and support. found in and around most body structures
dense fibrous / tendon tissue
makes strong attachments between structures, forms tendons and most ligaments
elastic tissue
allows stretching in various organs, found in lung tissue, vocal cords
reticular tissue
binds smooth muscle tissue cells, found in the storm of liver, spleen, lymph nodes
adipose tissue
fat storage, reduces heat loss, conserves energy. found wherever areolar tissue is located
bone
functions in support, protection and storage. makes up all bones in the body
blood
RBCs transfer oxygen and co2, WBCs carry oh phagocytosis, platelets prevent clotting
