D none of the above are NOT functions of the epithelium, ie they all are. But its a badly worded question.
The lining of the smallest tubules in the kidneys is composed of a single layer of specialized cells called renal tubular epithelial cells. These cells play a crucial role in reabsorbing essential substances from the filtrate and secreting waste products into the urine.
Glandular tissue, a type of epithelial tissue, is responsible for producing and secreting chemicals and fluids. This tissue forms glands, which can be classified as endocrine glands (releasing hormones directly into the bloodstream) or exocrine glands (secreting substances through ducts to the surface of organs or tissues). Examples of secretions include sweat, saliva, and digestive enzymes.
Amoebas, specifically certain species like foraminifera and testate amoebae, form shells by secreting mineral materials or organic substances. These shells, often called tests, can be made from calcium carbonate, silica, or organic compounds. The amoeba secretes these materials layer by layer, often incorporating environmental particles into the structure, which provides protection and aids in buoyancy. Over time, these shells can accumulate and contribute to sediment formation in aquatic environments.
The type of epithelial tissue that lines the digestive tract and contains mucus-secreting goblet cells is simple columnar epithelium. This tissue is specialized for absorption and secretion, playing a crucial role in protecting the intestinal lining and facilitating the movement of food through the digestive system. The mucus produced by the goblet cells helps to lubricate the digestive tract and protect it from digestive acids and enzymes.
Mucus-secreting goblet cells are not found in the nervous or skeletal systems.
mast cells
is: Synovial membrane
Their apparent number of layers;simple epithelium with a single-layer offer less protection than Stratified epithelium having multiple layers. Also, simple epithelium functions in moving materials across its surface.
Goblet cell. It's responsible for secreting mucus, which helps protect and lubricate the epithelial surface.
The lining of the smallest tubules in the kidneys is composed of a single layer of specialized cells called renal tubular epithelial cells. These cells play a crucial role in reabsorbing essential substances from the filtrate and secreting waste products into the urine.
Mucus and cilia are commonly found wedged between simple columnar epithelial cells. The mucus helps to trap debris and pathogens, while the cilia help to move the mucus and its contents along the surface of the cells.
The function of epithelium tissue is mainly to protect the tissues below it from desiccation and radiation. The other functions include secretion of hormones into the blood system and provide sensation.
Your testes start secreting testosterone during puberty.
endocrineEndocrine
A general medical term for a hormone secreting cancerous tumor
Epithelial tissue is a type of tissue that lines the surfaces of organs and body cavities, as well as forms glands. It serves as a protective barrier, absorbing and secreting substances. Epithelial cells are tightly packed together, providing a smooth and continuous layer.
Epithelial tissue is the type of tissue that contains cells capable of absorbing or secreting substances. This tissue forms the lining of various organs and structures in the body and plays a crucial role in functions like absorption in the intestines and secretion in glands.
