They are known as "cilia"
Cilia are hairlike structures located in the respiratory system. They help to sweep mucus and foreign particles out of the airways, assisting in the protection of the lungs from potential irritants or infections.
The wing generates lift, which propels the aircraft upward due to differences in air pressure on the upper and lower surfaces of the wing. So, the wing is being pushed upward.
The law of motion illustrated by a rocket taking off is Newton's Third Law of Motion which states that for every action, there is an equal and opposite reaction. The rocket propels itself upward by expelling gases downward, creating a reaction force that propels it forward and upward.

True
True. The cilia in the trachea sweep mucus upward, where it is then transported to the back of the throat and eventually swallowed or coughed out. If there is an excess amount that reaches the nose, it can trigger a sneeze reflex to expel it.

The heart, aorta, esophagus, and trachea are all located in the thoracic cavity. The heart is situated between the lungs in the mediastinum, with the aorta arching upward from the heart. The trachea runs anterior to the esophagus and extends from the larynx to the bronchi, branching off into the lungs. The esophagus lies posterior to the trachea, connecting the throat to the stomach.
Cilia are hair-like structures found in the respiratory tract that sweep mucus and trapped particles upward towards the pharynx, where they can be coughed up or swallowed.
The two main forces acting on a rocket during takeoff are thrust, which propels the rocket upward, and gravity, which pulls the rocket downward.
The trachea is supported by C-shaped rings of cartilage. The point at which there is no cartilage is where the trachea is in contact with the oesophagus. As a large bolus of food passes down the oesophagus the elastic walls expand to accommodate it. This is made possible by the absence of cartilage on the trachea. However, the trachea is prevented from collapsing due to the supporting cartilage around the rest of it.
