Document Summary
Di erentation and growth of tissues and organs during development. After gastruation, internal organs begin to be formed. Tissue interactions are crucial for the formation of internal organs scubas digestive tract, the pancreas and lungs. Period during development when the internal organs are being formed. An organ is composed of a group of tissues that work in a coordinated manner to perform a speci c function. Most organogenesis begins by 5th wk of gestation in humans. In the embryo, internal organs are forming such as liver, pancreas, lungs and gi tract. Two important interacting tissues during organogenesis of internal organs- iec and. Basement membrane: a specialized, sheet like structure that separates epithelial cells from the surrounding connective tissue. consist of extracellular metric proteins held together by collagen. Arranged in a layer of sheet of cells. Cells exhibit polarity- apical surface and basal surface apical = microvilli for absorption, cilia for movement.
