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)
Connective tissue is the most common tissue in the human body. It is primarily used for structural support and protection. It covers a wide variety of uses. Blood, bone, lymph, and cartilage tissues are considered connective tissue.Muscle tissue is involved with the contraction of muscle fibers.here are four different types of human tissues: epithelial, connective, muscle, and nerve. They are each discussed below. Epithelial tissue is lining tissue. It composes the skin and linings of internal body cavities.
