Answer:

1)are animal tissues. The cells that are present in these tissues show all the characteristics of animal cells. The cells are eukaryotic with a nucleus and membrane-bound organelles. Animal cells do not have a cell wall and this is what gives them flexibility. The cells of the tissue can take up different shapes to become specialized and perform specific functions.

And so, epithelial tissues have cells that have different shapes, sizes, and arrangements. Accordingly, they are classified into different types. Epithelial cells can be seen in different parts of the body. They cover the body’s surface and also line the internal body organs and body cavities.

2)Simple squamous epithelia are found in a variety of locations, starting from capillaries to the alveoli of lungs, and nephrons of kidneys. Most of these cells arise from the ectoderm, or outermost layer of cells in the embryo. However, some simple squamous epithelial tissues are also derived from the mesoderm or middle layer of embryonic cells. These are called the mesothelia, especially in pathological studies. These tissues line several body cavities including the pleural cavity that houses the lungs, peritoneum (abdominal cavity containing the stomach and intestines) and the mediastinum (part of the thoracic cavity that contains the heart, lungs, trachea and esophagus). These tissues are also called the endothelium when they form the inner lining of blood and lymph vessels.

3)Our bodies are made up of different types of tissues or materials. These include the bones and blood (connective tissue), different types of muscles (muscle tissue), and the brain, nerves, and spinal cord (nervous tissue). However, the surface of our body needs to be protected from elements like sunlight and wind, and so do our delicate organs which are located in empty spaces. At the same time, the body needs to control which substances are present inside it, and which are being removed. All these roles are played by a kind of thin tissue called the ‘epithelium.’ However, this epithelium may be made of a single layer of cells called simple epithelium, or several layers called stratified epithelium. In the following sections, we will learn about a type of simple epithelium, called the simple cuboidal epithelium.

4)Ciliated Epithelial cells in respiratory tract.

simple columnar epithelium in intestinal lining.

Explanation

In Respiratory tract......

Ciliated Epithelial cells(group of cells is tissue), move mucous that contains dust and bacteria out of the body. The Ciliated Epithelial tissue prompts you sneeze and also helps you to be healthy.

In Intestinal Lining.......

The mucosa of the small intestine is lined by a simple columnar epithelium which consists primarily of absorptive cells (enterocytes), with scattered goblet cells and occasional enteroendocrine cells.

Glandular epithelium is such type of a tissue that is responsible for the formation of glands. This Bodytomy article talks about the location and characteristic of the glandular epithelium.
