Compare and contrast between type I and type II muscle fibers. Its function is to produce and maintain the ECM of connective tissue. However, the free surface of the cells lining the small intestine is covered with microvilli, which increases the surface area for absorption of nutrients from the small intestine. -connective tissue has relatively few cells with lots of extracellular material. The secretions of endocrine glands, called hormones, diffuse into the bloodstream without flowing through a duct. Blood is a connective tissue that is important for the transport of various materials like gases and nutrients. Blood is also an exception It is further divided into simple and stratified epithelium on the basis of their complexity and the number of layers of cells. What tissues fulfill these needs? Connective tissue is the major supporting tissue in our body. It has almost equal amounts of cells, fibers and ground substance.

The specialised cell and ECM nature of bone allows it to serve as a storage site for calcium and phosphate, alongside its weight bearing and protection functions. In nervous tissue, the electrical impulse can travel long distances and is used as a form of communication. Embryonic connective tissue is found in the early embryos and umbilical cord. Privacy. Depending on how the lipids are distributed within the cell; there are white and brown adipose tissues. tissue of the esophagus. The glandular epithelium lines various glands and their ducts throughout the body, which then later proliferate to produce various hormones and enzymes. Identify and describe (structure, function, tissue types) the layers of the dermis. The cells of the epithelial tissue are arranged cellular sheets either in single or multiple layers. The cells of the connective tissue are formed from embryonic cells called mesenchymal cells. Direct link to Aaron's post It's boring but interesti, Posted 3 years ago. Columnar epithelium in the stomach doesnt have any surface structures. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified. Blood Blood is a fluid connective tissue.
