Which type of epithelium lines the inferior portions of the pharynx?

Biology
1 answer:
konstantin123 [22]3 years ago
7 0

Answer:

The type of epithelium that lines the inferior portions of the pharynx is stratified squamous epithelium.

Explanation:

The pharynx is a structure made up of muscles and mucous membranes -like many internal organs- that is part of the respiratory system and is an intermediate step in the digestive tract.

This structure has two portions:

  • <em>Upper or nasopharynx </em>
  • <em>Lower, or oropharynx, in contact with the airways. </em>

Some even propose that the borderline surface between the pharynx and larynx can be called the laryngopharynx, due to its tissue structure.

The lower portion of the pharynx is covered by a squamous stratified epithelium, the inner layers of which rest on a basal lamina. The more superficial layers provide protection to the interior of the pharynx against friction, in addition to remaining lubricated by mucous secretion at that level.

True or false? in host-versus-graft rejection, the recipient recognizes the donor tissue as foreign and rejects the transplant;
snow_tiger [21]
The statements above are true;
In a host-versus-graft rejection the recipient's immune system recognizes the donor's tissue as foreign and rejects the transplant. On the other hand, in a graft-versus-host rejection, the donor tissue recognizes the recipient's tissue as foreign and the transplant rejects the recipient, causing destruction of the recipient's tissue and possibly death. Its important also to note that there are two types of rejection, the acute rejection, where the rejection of transplanted tissue that occurs several weeks after transplant. it is delayed hypersensitivity reaction, and the chronic rejection is a rejection of transplanted tissue that can occur at a late time. Immune complexes form in the arteries supplying the graft, choking off the blood supply and the tissue is rejected.

Which of the statements describes characteristics of eukaryotic cells but not of prokaryotic cells? O two or more linear chromos
gtnhenbr [62]

O relatively large genome, dynamic cytoskeleton, compartmentalized metabolic processes

Explanation:

Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. 

DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.

Eukaryotic cells generally use aerobic respiration – requiring oxygen – to produce usable energy called ATP from glucose molecules. ... Prokaryotic cells, on the other hand, tend to use anaerobic respiration – not requiring oxygen.
