Which cells may absorb protect or form a filtering membrane?
Epithelium (Lol, Mr. Post's class?)
What organ does tissues in groups form?
Animal tissues can be grouped into four basic types: connective, muscle, nervous, and epithelial. Multiple tissue types comprise organs and body structures. While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals. The epithelium in all animals is derived from the ectoderm and endoderm with a small contribution from themesoderm which forms the endothelium. Generally, cells differentiate into different tissues depending on the tissues surrounding them.

The epithelium in all animals is derived from the ectoderm and endoderm with a small contribution from the mesoderm which forms the endothelium. By contrast, a true epithelial tissue is present only in a single layer of cells held together via occluding junctions called tight junctions, to create a selectively permeable barrier. This tissue covers all organismal surfaces that come in contact with the external environment such as the skin, the airways, and the digestive tract. It serves functions of protection, secretion, and absorption, and is separated from other tissues below by a basal lamina. Endothelium, which comprises the vasculature, is a specialized type of epithelium.
Are there any human tissues that may be relatively more easily obtained for study?
Newer studies do suggest that adult stem cells may have cells that are not easily grown after isolation from mature adult tissues.
What will happen to the organs like the heart kidneys and the parts that make them up if the tissues were injured or diseased?
If an organ's tissues are injured or diseased, the organ may not function properly. This, in turn, could cause damage to other organs and tissues in the body.

What tissue contains cells that may absorb or secret substances?
epithelium
Where do groups of tissues form?

What cell tissue may absorb and or secrete substances?
Connective tissue

How are tissues and organs different?
There may be several tissues in an organ but a tissue does not have many organs
Tissues which are normally difficult to discern with an optical microscope may be revealed by?
Tissues which are normally difficult to discern with an optical mictroscope may be revealed by stain.
Has cilia to trap and remove mucus and dust particles?

What is a structural characteristic of squamous epithelium?
There is different types of squamous epithelium: simple and stratified. The function of simple squamous epithelium:It is good for the passage of materials via diffusion. For example, it forms the tiny air sacs of the lungs and the walls of capillaries. It also forms the smooth, friction-reducing interior lining of the heart, blood vessels, thoracic cavity, and abdominal cavity. The function of the stratifed squamous epithelium: It functions to protect underlying tissues in areas subjected to abrasion. The keratinized type forms the outermost layer of the skin, where it functions to prevent water loss. The nonkeratinized variety forms the moist linings of the mouth,esophagus, anus, vagina.
