During breathing air enters the nose by passing through the external nares( nostrils)=> pharynx=>larynx=> trachea=> The trachea (windpipe) divides into two main bronchi (also mainstem bronchi), the left main bronchus and right main bronchus. The right main bronchus subdivides into three lobar bronchi while the left main bronchus divides into two. The lobar bronchi divide into => tertiary bronchi, also known as segmental bronchi, each of which supplies a => bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is separated from the rest of the lung by a connective tissue septum.. There are ten segments per lung, but due to anatomic development, several segmental bronchi in the left lung fuse, giving rise to eight. The segmental bronchi divide into many => primary bronchioles which divide into =>terminal bronchioles, each of which then gives rise to several => respiratory bronchioles, which go on to divide into 2 to 11 => alveolar ducts. There are 5 or 6 =>alveolar sacs associated with each alveolar duct. The alveolus is the basic anatomical unit of gas exchange in the lung.

Trace a molecule of oxygen from the atmosphere through the external respiratory system?
external nares->nasal cavity->nasal conhae->nasopharnx->oropharnx-> laryngopharnx->trachea->primary bronchus->secondary bronchus-> tertiary bonchus->terinal bronchiole->respiratory bronchiles->alveolar duct-> alveolus
Importance of trace route in Windows XP?
its important coz its good for the heart,.. nah.. joke only, it will trace the time differential that took place on the connection upon access on a website
What body of water flows into the Mississippi river from the west?
Open your book, look at the map, trace the route of the river.
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 commands is used to ping a multi-function device?
The trace route command is used to ping a multi-function device.
What was the principle route between natchez and nashville?
The principal route between Natchez, Mississippi, and Nashville, Tennessee, historically followed the Natchez Trace, an ancient trail used by Native Americans and later by European settlers. The Trace connected the Mississippi River at Natchez to the Cumberland River at Nashville, facilitating trade and travel. This route was significant in the early 19th century for commerce and migration, serving as a key artery for those moving westward. Today, the Natchez Trace Parkway preserves much of this historic path as a scenic drive.
How do you find the distance of a certain route on certain streets in a city?
if you have a paper map, then using string to trace the route then measuring it, then converting that distance to the known map scale will work. Otherwise google maps does a pretty good job, if you drag the route to the streets you want to use.
