Ischemia
The word "ischemia" () is from Greek ἴσχαιμος "iskhaimos", "staunching blood" from ἴσχω "iskhο", "keep back, restrain" and αἷμα "haima", "blood".
Phlegm
Phlegm was thought to be associated with apathetic behaviour; this old belief is preserved in the word "phlegmatic". This adjective always refers to behaviour, and is pronounced differently, giving full weight to the "g": not /ˈflɛmatɪk/ but /flɛgˈmatɪk/. To have "phlegm" traditionally meant to have stamina and to be unswayed by emotion. Sir William Osler’s 1889 Aequanimitas discusses the imperturbability or calmness in a storm required of physicians. "'Imperturbability means coolness and presence of mind under all circumstances, calmness amid storm, clearness of judgment in moments of grave peril, immobility, impassiveness, or, to use an old and expressive word, phlegm."" This was his farewell speech at the University of Pennsylvania in 1889 before becoming Physician-in-Chief at the recently founded Johns Hopkins Hospital in Baltimore, Maryland. This is from ""Celebrating the Contributions of William Osler"" in the Alan Mason Chesney Medical Archives of the Johns Hopkins Medical Institutions.""
