How do the epithelia of these two organs relate to their specific functions? The esophagus is subjected to constant abrasion…
Mucous membranes are composed of epithelial cells lying on top of loose connective tissues. Serous membranes are epithelial cells that are attached to a small amount of areolar connective tissues. These membranes are unique because they occur in two layers. Synovial membranes are composed entirely of connective tissue and are found lining the cavities around the joints. These membranes help provide a smooth surface for the…
The epithelial tissue of the small intestine lack villi and only contains crypts. The tunica mucosa has an increased amount of goblet cells. The tunica submucosa are populated with adipose tissue. The tunica muscular is substantially thinner. The rectum tunica mucosa starts out as a simple columnar epithelium and gradually changes to a stratified squamous epithelium as…
Which of the following is a single-celled layer of epithelium that forms the lining of serous membranes?…
Epithelial tissues are the inside layer of internal and external surfaces and body cavities, including ducts carrying secretions from glands. They may be composed of some layers of cells, called compound epithelia or just a single layer which is known as simple epithelia. The lowest or bottom layer of cells is attached to the basement membrane for support and connection. Part of the basement membrane is concealed by the epithelia but they are supplied with oxygen and nutrients from deeper tissues by diffusion which is the passage of the molecules from a high concentration to a low concentration. As they are surface tissues and exposed to friction, their ability for growth and repair is greater than other tissues and generally occurs during sleep.…

Epithelial Tissue covers the body surface and forms the lining for most internal cavities. It protects our insides, it’s known as the skin. It also absorbs in the intestinal lining and stomach, otherwise known as the gut. It also filters in the kidneys and secretes(forms glands). Epithelial cells are attached to each other closely forming a protective barrier and have no blood vessels but can soak up nutrients from blood vessels in connective tissue from underneath. It protects the body from dirt, dust, bacteria and other microbes which could harm you. It is innervated which means it has a lot of nerves in it and it is very good at regenerating for example having a grazed knee or sunburn. It also protects the main organ which is the heart, from rubbing against and harming the lobes in the heart against lungs. It gives us an extra barrier for security and saves the heart from many different injuries and also helps protect the upper body around the heart area.…
4) Mucous membranes (p.447): Mucous membranes line all body cavities open to environment. (i.e. lumens of the respiratory, urinary, digestive, and reproductive tract. nonspecific defenders…
1. lines body cavities and covers the body’s external surface 2. pumps blood, flushes urine out of the body, allows one to swing a bat 3. transmits electrochemical impulses 4. anchors, packages, and supports body organs 5. cells may absorb, secrete, and filter 6. most involved in regulating and controlling body functions 7. major function is to contract 8. synthesizes hormones 9. the most durable tissue type 10. abundant nonliving extracellular matrix 11. most widespread tissue in the body 12. forms nerves and the brain…
This tissue is specialised to cover the whole part of the body lining of all of the internal and external body surfaces, they are packed tightly together to form continuous layers that serve as linings in different parts of the body. Epithelial tissue serves as membranes lining organs and helping to keep the body's organs separate, in place and protected. Some examples of epithelial tissue are the outer layer of the skin, the inside of the mouth and stomach, and the tissue surrounding the body's organs.…
