The average diameter of the adult windpipe (or trachea) is 2.5cm (1 inch).
The average poop diameter of a healthy adult human is about 1 to 1.5 inches.
The normal poop diameter for a healthy adult is typically around 1 to 1.5 inches.
The size of a human eye is the size of a golfball.But most of the eye is inside your head.The size of an eye of an average person will never change. If you want more detail or information go to http://wikipedia.com/eyes or you can read the book called "The human body".
The average cell diameter in the human body is about 10-20 micrometers, which is equivalent to 10,000-20,000 nanometers.
On average, an adult's circulatory system contains about 5 to 6 liters of blood.
The average poop diameter of a healthy adult human is about 1 to 1.5 inches.
A child's airway differs from that of an adult in that the child's tongue is proportionately larger in the oropharynx compered to that of an adult. Also, a child's airway is smaller and softer and more prone to foreign body obstruction. An infant's airway is smaller and softer still and the trachea is usually about the diameter of a pencil.
On average, there are approximately 1500 miles of airways in an adult human.
Between species the diameter of the bronchi and bronchioles vary greatly. The average length of the adult bronchus is 2.5 cm and its average diameter is 13 mm.
an adult is over 18 old, an infant is under 2 years
The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.

The most common cause of airway occlusion (airway obstruction) is choking on foreign objects. This means swallowing an obstructive object or having something lodged in your trachea causing the airway to lose its patency.
The normal poop diameter for a healthy adult is typically around 1 to 1.5 inches.
Use the head tilt chin lift procedure to open the airway. See slide 13 of the related link for a picture.
