The trachea is structured in a way so that an individual can breathe at all times (in/voluntarily). The tracheal rings allow the trachea to stay open so that a person can breathe. The esophagus is flat b/c it is strictly for the passage of food, so it is not used as often as the trachea.
What else can I help you with?
What is the function of the cartilage surrounding the trachea?
they hold the trachea open, otherwise it would be squeezed flat like the esophagus when it is empty. the trachea also has bands of smooth muscle that allow the esophagus to expand into the trachea when swallowing. this is why you cant breathe and swallow at the same time.
Can testosterone reduce breast size?

into the thoracis and abdominopelvic cavity.
What does a straight line on an ECG represent?
A flat section of line indicates no muscular activity in the heart at that particular instant; a constantly flat line indicates heart failure.
What is the difference between rigid and flexible flat feet?
The main distinction between rigid and flexible flat feet is that the former have an arch visible when the foot is not bearing weight (such as when sitting or standing on tiptoes) but collapse when standing, whereas the latter have no arch at all, regardless of whether weight is being placed on the foot.
Why you need to wear suitable shoes when you driving?
Flat-soled, rigid shoes let the driver have more control over the pedals.
What type of bone is used for protection-?
Skull and Ribcage!
What is a flat part of the earth called?

What is the maximum outboard for a flat force 3 rigid inflatable boat?
It is a 25hp outboard. this will get it on the plane pretty quick, i have one myself and it goes around 25-30 knots
What is esophageal squamous and glandular mucosa?
Esophageal squamous mucosa refers to the thin, flat epithelial lining of the esophagus, primarily composed of stratified squamous cells that protect against abrasion from food. In contrast, glandular mucosa is found in the lower part of the esophagus, where it contains specialized glands that secrete mucus and other substances to aid digestion and protect the esophageal lining. Together, these mucosal types play crucial roles in the overall function and health of the esophagus.
Why is a rigid Gill surface more advantageous than a flat Gill surface?
A rigid gill surface is more advantageous than a flat gill surface because it enhances the efficiency of gas exchange in aquatic organisms. The structural rigidity allows for greater surface area and increased water flow, facilitating the extraction of oxygen and the removal of carbon dioxide. Additionally, a rigid structure can better withstand the mechanical forces of water currents, ensuring that the gill remains functional under varying environmental conditions. This design ultimately supports more effective respiration and overall survival in aquatic environments.
