This is also heterogeneous, i.e. a composite of carbon-poor iron and cementite. Going to very fast cooling (quenching) will result in a single-phase (not composite) material called martensite. Here the carbon doesn't have time to exit the iron, and this martensite phase is very hard, but also normally too brittle.
Epithelial tissue - to cover the inner and outer surfaces of the stomach The stomach is one of the organs that form the digestive system. The stomach contains various tissues, and each tissue is made of a particular type of cell. In order of increasing size and complexity: cells â tissues â organ (the stomach) â organ system (the digestive system)
Ordinary connective tissue, or connective tissue proper , is a generalized form of connective tissue which contains all of the basic components of connective tissue in reasonable proportion, including cells (of several types), extracellular fibers, and extracellular ground substance.onnective tissue comprises one of the four basic tissue types. The others are: epithelial tissue (surfaces and glands), muscle tissue (contractile cells), and nervous tissue. Organs represent various combinations of these four basic tissue types, which thus comprise the entire body.
