For instance, the upper digestive tract anatomy offers some review of the pulmonary systems (since our throats branch into the trachea and the esophagus). My favorite is Dr. Matt and Dr. Mike’s Medical Podcast. Since it’s been so valuable to me, I offered my support by buying one of...
Air enters the lungs through the mouth and nose, traveling through the trachea (windpipe) into the bronchial tubes. These tubes branch into progressively smaller segments until they reach blind sacs called alveoli. Here, the air is separated from red blood cells in the capillary blood vessels by...

(the tubes that branch from the trachea into the lungs) sounds deeper and raspier. An irritation in the larynx (also called the voice box) causes the cough to sound like a bark. The way a cough sounds doesn't always indicate what's triggering the cough, though it may be an important...
Our heads that are too large for our spindly necks and our skulls too thin to protect the brain. The oesophagus being dangerously close to the trachea can cause us to choke. The appendix is more likely to kill us than be of any use. In men the testicles have to hang outside the body...
Think of your respiratory tract as an upside-down tree. The trunk is your trachea, or windpipe. It splits into smaller and smaller branches in your lungs. At the end of each branch are tiny air sacs called alveoli. This is where oxygen goes into your blood and carbon dioxide comes out...
Members of the dragon tree group are usually defined by a few general traits, which are: arborescent habit, excretion of the red resin, leaving a closely packed pattern on the bark, closely packed leaves at branch apices with a lack of distinctive internodes, leaf sheaths differentiated in ...
