The alveolar duct primarily consists of smooth muscle and elastin fibers but contains minimal connective tissue. Its structure is designed to facilitate the passage of air to the alveoli, where gas exchange occurs. While there is some connective tissue present to provide support, it is not a major component of the alveolar duct's architecture.

Does the alveolar duct have cartilage?

No, the alveolar duct does not have cartilage. It is a structure within the lungs that connects the respiratory bronchioles to the alveolar sacs where gas exchange occurs. Cartilage is primarily found in the larger airways of the respiratory system to provide structural support and maintain airway patency.


Distinguish between a simple gland compound gland tubular gland and alveolar gland?

A simple gland consists of a single unbranched duct, while a compound gland has a branched duct system. Tubular glands have a tube-like structure, while alveolar glands have a round, sac-like structure. Alveolar glands are also known as acinar glands and contain clusters of secretory cells that form small sacs.

What is the direction of movement of gas between the blood and the alveolar duct?

Gas moves by diffusion from areas of high concentration to areas of low concentration. In the lungs, oxygen moves from the alveolar ducts into the blood in the capillaries, while carbon dioxide moves from the blood into the alveolar ducts to be exhaled.


What is a gland composed of cells arranged in a blind pocket with a single duct that does not branch?

The gland you're describing is a simple acinar gland. It consists of secretory cells arranged in a spherical or flask-like structure with a single unbranched duct that carries the secretions to the surface. This type of gland is common in structures like the salivary glands and sebaceous glands.


Trace molecule of oxygen from the external nares to the pulmonary capillaries of the lungs?

nose - nasal cavity - larynx - trachea - primary bronchus - secondary bronchi - tertiary bronchi - terminal bronchi oles - respiratory bronchioles - alveoli - alveolar sacs the alveolar sacs contain the pulmonary capillaries. the actual gas exchange occur here by simple diffusion. O2 goes from the lungs into the O2 depleted RBC.

What is the structure of alveolar ducts?

it dissolves oxygen in the fluid and from there it can diffuse to the alveolar cells.It goes right back to evolution where single cells have to absorb oxygen from water.All of our cells systems ae aquatic.
