Hope this helps! 1 What is a similarity between epithelial and connective tissue? What does connective tissue look like? Chief cells are mesenchymal cells. The tendons and ligaments found throughout the body act as a connecting medium for bones, muscles, and cartilages. a. Connective tissue and muscle tissue are two of the four basic types of tissues in our body. The simple columnar epithelium is present as a lining epithelium in many organs and is often changed to make it well suited for a specific function. The blood cells, also called the formed elements, carried by plasma are the erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). Cartilage is the avascular connective tissue that connects bones at joints and comprises walls of upper respiratory airways and external ear. The nutrition in cells of connective tissue is obtained through blood in the blood vessels. Epithelial tissue forms the covering of various organs and thus is the outermost tissue in most organs. Because bone tissue is connective tissue, it is highly vascularized and is surrounded by several other connective tissues. The lining of your intestines. Bones are mineralized tissues consisting of other types of tissues within them like the bone marrow, periosteum, endosteum, and blood vessels. The first we'll talk Privacy. there, those little dots.

Epithelial tissue is found in various organs like skin, buccal cavity, the lining of blood vessels, body cavities, glands, and their ducts. All substances that enter or leave an organ must cross the epithelial tissue first. Tissues are organized into four broad categories based on structural and functional similarities. Multicellular, complex animals have four primary types of tissue: epithelial, connective, muscle, and nervous. Waugh A and Grant A (2004). Mucoid connective tissue is found in the umbilical cord. into these neat categories. Do all cells have extracellular matrix and fibers or just connective tissue cells? These are the cells of the immune system (macrophages, lymphocytes and mast cells) and adipocytes.
