A May 2011 discussion on SoloSez, the email listserv for general practice, solo and small firm lawyers. At the beginning of this year, I started charging a consultation fee of a little less than my hourly rate. If the potential client retains me, I apply the consultation fee to their first invoice. I've had a surprising number of people opt for the consultation, even with the fee.
The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.
It also filters the air while it's in the windpipe. The average adult windpipe is about 12cm in length and 2cm in diameter. Blood Vessels- In our lungs, we have air sacs that are called alveoli. Blood vessels cover each alveoli that connect to a system of veins and arteries that move blood through our body. The oxygen then spreads into the blood vessels so that the heart can pump it to different parts of the body.
