Explanation:

1)The nasal cavity functions to allow air to enter the respiratory system upon respiration. Structures within the cavity regulate the flow of air and particles it contains. The olfactory region of the nasal cavity regulates the sense of smell

2)Nose hair is a natural part of the human body that serves as a defense system. Nasal hair keeps harmful debris out of the body system and maintains moisture in the air we breathe. Blood vessels in the nose and face are extra dense. In the nose, they support hair growth

3)Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated.

4)its function is to regulate the passage of air to the lungs and food to the esophagus. The pharynx, or throat, is the passageway leading from the mouth and nose to the esophagus and larynx

5)The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled

6)The glottis, a slit-like opening on the floor of the pharynx, is a valve that controls airflow in and out of the respiratory passages. The glottis opens directly into a box-like larynx.

7)Function. The trachea is one part of the respiratory tree, that is a conduit for air to pass through on its way to or from the alveoli of the lungs. This transmits oxygen to the body and removes carbon dioxide.

8)In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue. The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.

9)The larynx , commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The larynx houses the vocal folds, and manipulates pitch and volume, which is essential for phonation.

10)There are as many as 700 million alveoli in each lungs, where they facilitate gaseous exchange of oxygen and carbon dioxide between inhaled air and the bloodstream. This article will discuss the anatomy and function of the alveoli.
