Answer:

1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .

2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

Which type of epithelium is composed of multiple layers, including an apical layer containing tall, slender cells?
Mademuasel [1]

The question is incomplete as it does not have the options which are:

  • Simple squamous
  • Simple columnar
  • Pseudostratified squamous
  • Stratified squamous
  • Stratified columnar

Answer:

Stratified columnar

Explanation:

Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.

In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.

Therefore,  the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.

Thus,  Stratified columnar is the correct answer.

andrey2020 [161]

Answer:

C

As the Earth moves in relative to the moon the Earth blocks part of the sun from the moon causing only parts of the moon to light up. This BEST answers the question because B is not accurate because it doesn't describe why we actually SEE it. A might be true but it is not the BEST explained.

Hope this helps! (^-^)
