Oropharynx
The areas of the pharynx are the Nasopharynx, Oropharynx, and Laryngopharynx. The nasopharynx it provides passageway for air. The oropharynx is below the nasopharynx and is for food moving downward from the mouth and for air moving to and from the nasal cavity. Lastly the laryngopharynx is below the oropharynx and is a passageway to the esophagus.
The oropharynx is the space behind the oral cavity and above the laryngopharynx.
The vocal cords, or vocal folds, are situated in the larynx, which is located in the throat, just above the trachea (windpipe). They are composed of multiple layers of tissue and are responsible for producing sound when air passes through them, causing them to vibrate. The larynx is also involved in protecting the airway during swallowing.
Oropharynx
The pharynx
The air you breathe in through your nose goes through your nostrils, pass something called turbinates (also called concha, which warm the air), then enter the nasopharynx, which is the area above your uvula (You can´t see it witout a proffessional mirror). Then it enters the oropharynx (the very back of your thoat) and from there it follows the same path as the air you breathe in through your mouth. Namely Larynx-->Trachea-->Bronchi--> Alveoli. From there the air diffuses into bloodvessels lining the alveoli.
The upper part of the respiratory system is also called the conducting portion.It consists of all the structures of the respiratory system outside of the lungs:Nose, nasal cavity, paranasal sinusesPharynx, larynx, trachea
Tissue paper is not very dense. I assume it is one piece and is on a flat surface. When blowing down straight and in the middle, air is able to move through the tissue paper because it is porous. You keep forcing air down and the molecules are bombarding each other and when completely through the tissue paper the fastest way to escape and allow the other molecules through is by escaping under the tissue paper and outwards. This is what lifts the tissue paper.

Your throat is not an organ. The throat contains the larynx and pharynx organs. The larynx, commonly known as the voice box, is part of your respiratory system. The pharynx behind the mouth and nasal cavity and above the larynx and esophagus.
The pharynx consists of three sections. The upper portion of the pharynx (from the base of the skull to the top of the soft palate) is called the nasopharynx. Beneath the oral cavity lies the oropharynx. The final portion, the laryngopharynx, is the part of the throat that is connected to the esophagus.
