What kind of tissue makes up vocal cords?

A. ciliated simple columnar epithelium:The uterine (fallopian) tubes are lined with ciliated simple columnar epithelium. The cilia help move the ovum from the ovary toward the uterus, while secretory cells provide nourishment for the ovum and early embryo.

B. smooth MT:Smooth muscle tissue is present in the walls of the uterine tubes to aid peristaltic movement, but it does not line the lumen. The lining is provided by epithelial tissue, not muscle tissue.

C. simple cuboidal epithelium:Simple cuboidal cells are commonly found in glandular tissues and kidney tubules, where they function in secretion and absorption. They do not have the cilia required for egg transport in the uterine tubes.

D. stratified squamous epithelium:Stratified squamous epithelium is specialized for protection in areas exposed to friction, such as the skin and vaginal canal. It is not suitable for the transport and nourishment functions of the uterine tubes.

A. simple cuboidal epithelium:Simple cuboidal epithelium is commonly found in glands and kidney tubules where secretion and absorption occur. It does not line blood vessels or play a role in preventing clot formation.

B. transitional epithelium:Transitional epithelium is specialized for stretching and is found in the urinary bladder and ureters. It is not present in blood or lymphatic vessels, so it does not influence clot prevention.

C. mesothelium:Mesothelium lines body cavities such as the pleura, peritoneum, and pericardium. Its function is to reduce friction between organs, not to maintain smooth blood flow within vessels.

D. endothelium:Endothelium is the thin layer of simple squamous epithelium lining blood and lymphatic vessels. A healthy endothelium provides a smooth, non-thrombogenic surface that prevents clots from adhering to the vessel wall.
