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)
Membranes Body membranes are thin sheets of tissue that cover the body, line body cavities, and cover organs within the cavities in hollow organs. They can be categorized into epithelial and connective tissue membrane. There are three types of epithelial membranes: 1. Mucous membranes 2.
