THE LONG-LOST LUNGS

OK, weird topic…I get it.
But my heart goes out to smokers, especially those who smoke so much and know only next to nothing about what harm they are doing to their body systems.
So, I would love to educate in a few sentences.
First, the airways are lined by mucus.
Secondly, there’s this other lining, known as epithelium on all body tissues, and its of several types. Now, repeated smoking episodes cause the epithelial lining of the lungs (ciliated columnar epithelium) is transformed to a stronger type of epithelium (squamous epithelium).
If you think stronger always means better, you are fatally wrong in this case, because here, stronger means less protective but more adaptive to smoke. In actual fact, the tissue metaplasia (i.e. change from one cell type to another) seen here is a double-edged sword, because though it causes the respiratory system to have better survival chances in smokers, it still predisposes that person to the development of lung cancer. And many of us know that cancer spreads like wild-fire.
Those are just a few disadvantages of smoking.
A little advice: Don’t smoke for fun if you do not want your lungs to be lost to you…a word, they say is enough for the wise.
But sometimes, even the wisest of us need more than a word…don’t we?

SALIENT LESSONS FROM THE CORONARY ARTERIES The coronary arteries provide blood supply to the heart, the blood pump. Some of its duties are outlined and deductions are saliently made from them. 1.       REPLENISHMENT: The first lesson to take from the coronary artery is that it replenishes the heart. While performing the work of pumping blood to other tissues, the cardiac muscle is replenished by means of its 2 coronary arteries. 2.       DIRECTLY SOURCED: The coronary arteries, unsurprisingly, take origin from the aorta, the main artery leaving the left ventricle, carrying oxygenated blood to all branch arteries of the human body. Thus, it originates from the principal source of maximally oxygenated blood; this points to the fact that it reveres impartation and not opinions. 3.       PERFUSION: The coronary arteries ensure that blood gets to every part of the heart by means of its several branches.

 EPISODE 3 ‘Oya sorry now, we’re almost there.’ Felix kept saying as he partially carried his dear friend.  She wouldn’t hear the last of this episode once it was over, that much he knew! ‘Awww…you don’t know how painful awww… this is’ ‘Sorry, sorry’ ; he kept saying So they eventually got to the ER and after pulling out her card, used ‘medical student connection’ to see the resident that was on call in Internal Medicine unit. ‘Hello dear’ , Dr. Brown said, looking keenly at the girl that was almost doubled over in pain ‘I think you should lie down on that couch’ ‘What exactly is the problem?’ ‘She just started complaining about her abdomen about half an hour ago’ ‘Oh’. ‘Can you point to where exactly the pain started?’ he asked ‘Here’ . Linda pointed to the area around her umbilicus. ‘Have you had any episode of vomiting?’ ‘No sir’ Felix answered spontaneously. ‘You must be her boyfriend, right?’ Dr.Brown asked, with a mischievious grin ...

EPISODE 5 ‘So, really, whose patient is she?’ Doctor Afuarida asked with impatience written all over his face Bola indicated, her body language reeking of timidity, ‘Sir, she was supposed to be my patient, but I haven’t been able to clerk her’ ‘Oh, really? She was supposed to be?’ ‘Do you even have any other patient on the ward?’ ‘Ehm…no sir. But my other patient has just been discharged’ ‘Please, leave my ward round. You are obviously unprepared to truly learn the art of medicine.’ She knew better than to plead and therefore, walked out with the little dignity she still had left. He continued lecturing the rest of the students ‘You know, whatever you do now will speak later in life and especially in your medical career. If you want to be a good doctor, it definitely begins from now- taking responsibility’ Dr.Amao, please give me a summary on this patient ’22 year old female, had appendectomy done. 1 st day post-op. Mild pain at op-site. Currently on IV Met...
