The glottis is dividing line between the upper and lower airway
The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.
Compromised neonate is a medical term used to describe an airway that is restricted or blocked. This can either be in the upper airway or the lower airway.
The diaphragm

the bronchi divides into two, right and left. the right again divides into 3 lobar bronchiloes for three lobes- upper, middle and lower. while the left divides into 2 lobar bronchioles for the two lobes of left lung i.e upper and lower.
The plane that cuts the body into upper and lower halves is called the transverse plane, also known as the horizontal plane. This plane divides the body into superior (upper) and inferior (lower) sections.
Axial plane (Transverse Plane) which is a horizontal plane that divides the body or any of its parts into upper and lower parts. If you mean the entire body, it runs horizontality through the umbilicus or navel.
Prolonged inspiration indicates and upper airway obstruction and prolonged expiration indicates a lower airway obstruction according to Brady Emergency Care 12th Ed.
The plane that divides the body into upper and lower portions is called the transverse plane, also known as the horizontal plane. This plane runs horizontally from side to side, separating the body into the top (superior) and bottom (inferior) halves. It is commonly used in anatomical and medical contexts to help describe the location of structures within the body.
thyroid
The anatomical plane that separates the upper body from the lower body is called the transverse plane. This plane runs horizontally across the body and divides it into superior (upper) and inferior (lower) portions.
in a set as such {2,3,4,5,6,7,8,}, 5 would be the median, 7 would be the upper quartile, and 3 would be the lower quartile. The lower quartile divides the lower half of a set of data into two equal parts
