When PCs all had parallel bus architecture, the UART's purpose was to convert bytes from the PC's parallel bus to a serial bit-stream. The cable going out of the serial port is serial and has only one wire for each direction of flow. The serial port sends out a stream of bits, one bit at a time.
Three primary characteristics of connective tissue have been described as: Have a rich supply of blood vessels. Composed of many types of cells. Great deal of noncellular, â¦ nonliving material (matrix) between the cells of connective tissue.oose Connective Tissue consists of a lot of ground substance and it has all 3 types of protein fibers. Dense Connective Tissue on the other hand has little ground substance, â¦ few cells, and although it has most protein fibers it mainly consists of collagen fibers.
In contrast to epithelia, connective tissue is sparsely populated by cells and contains an extensive extracellular matrix consisting of protein fibers, glycoproteins, and proteoglycans. The function of this type of tissue is to provide structural and mechanical support for other tissues, and to mediate the exchange of nutrients and waste between the circulation and other tissues. These tissues have two principal components, an extracellular matrix and a variety of support cells. These two components will be the focus of this lab. Most frequently, the different types of connective tissues are specified by their content of three distinguishing types of extracellular fibers: collagenous fibers, elastic fibers, and reticular fibers.
