Nelco Amica Sewing Machine
I am very excited about my luck thrift purchases, particularly my Nelco Amica sewing machine. Heck, I’m ecstatic about my sewing machine. It’s the first one I ever bought for myself and I wasn’t counting on it working when I chanced buying it. But not only does it work, but it’s a champ. Sews through… continue reading
Mike
I made friends with one of my patients. Mike. Essentially, he had drinken too much in his lifetime – albeit a short one, maybe 55 years – and was dying of it when I met him. How trite. “His mortality was basically, like 90% when he walked through the door,” I overheard a chief resident… continue reading
A Recipe: Tiramisu
Caroline’s Tiramisu Recipe First you gotta brew about 2 cups of super-strength espresso (or have a local cafe do it for you), then put in some rum to taste (super strong). Put that aside. Buy two angel food cakes (or make ’em!) and cut them into 1/2″ strips; toast/broil until golden. Put that aside to… continue reading
Breathing, Part I
You’ve probably noticed already that breathing and respiration have a lot to do with chemistry, and that because you’ve most likely taken it for granted, it is surprisingly complex, dynamic, and interesting… This website is an overview of what happens as you breathe, starting with some basic anatomy and working into chemical principles that govern… continue reading
Breathing, Part II
What makes lungs expand and contract? Are they muscles? No, the lungs aren’t muscles. *Special* respiratory muscles “make” breathing happen. Normally an involuntary act, breathing can also be consciously controlled and altered, thank goodness. Although technically many muscles of the thorax can participate in breathing, any decent yogi will tell you that the diaphragm is… continue reading
Respiration, Part I
Breathing and respiration aren’t the same thing, but they go hand in hand. Breathing is a simple mechanical process whereby air enters and exits the lungs due to volume and hence, pressure changes. Respiration* is a more complex process of delivering oxygen to the tissues for cell metabolism and carbon dioxide to the lungs for… continue reading
Respiration, Part II
We’ve explained why air enters the lungs, what components flow in/out and why, but we still haven’t discussed internal and external respiration! Regard the image at right. Find the sad face. Here the blood is CO2 rich (45 mm Hg) and low in oxygen (40 mm Hg). This sad blood is being delivered to the… continue reading
Respiration, Part III
Oxygen and carbon dioxide are carried in the blood, pumped by the heart, and shifted through membranes by partial pressure gradients. Oxygen dissolves to a much smaller degree than carbon dioxide, so that at rest, the PO2 would only help provide 6% of the body’s O2 requirements. There must be another way. The hemoglobin molecule… continue reading
