French anatomist and pathologist Marie Franois Xavier Bichat introduced the term in 1801, stating that body functions could be understood better if they were studied at the level of tissues rather than organs. Connective tissue binds the various parts of the body together, providing support and protection. Xylem transports water and some soluble nutrients, while phloem transports organic compounds the plant uses as food, particularly sucrose. ThoughtCo. Such organisms are said to be triploblastic. In cartilage the matrix is firm but rubbery; in bone the matrix is rigid, being impregnated by hard crystals of inorganic salts. Fluid, Electrolyte, and Acid-Base Balance. then you must include on every digital page view the following attribution: Use the information below to generate a citation. The muscles shorten as they atrophy, which can cause scoliosis and immobile joints. Connective tissue usually develops from embryonic tissue referred to as mesenchyme. She specializes in teaching Human Physiology at USC. Smooth muscle does not have sarcomeres. Vascular tissue transports water and nutrients within a plant. The epithelial and connective tissues are discussed in detail in this chapter. It is made up of neurons, which are nerve cells, and neuroglia, which are cells that help nerve impulses travel.
