This is ridiculous. All of these classes (histology, embryo, biochem, etc...) are supremely important. You need the foundation to 1) communicate with other physicians, 2) read journal articles knowledgably, and 3) prescribe drugs safely
case 1) pt with a renal biopsy -- you need to know what your nephrologist and pathologist mean when they talk about crescentic glomerulonephritis instead of sitting there looking like an idiot.
case 2) pt with polypharmacy -- you need to know why and when and how hemoglobin folds the way it does so you can write orders to keep your sickler >96% SpO2 rather than letting them drift to the low 90s on less monitored floors, instead of letting them go into a VOC like an idiot.
case 3) embryology may be a little bit of a stretch but you still need to understand different kinds of ASDs, for example, as they are treated differently.
If you don't know the science, you're not a physician. You're a monkey with an Rx pad.
