ischemia
Ischemia (noun) means a reduced blood flow to part of the body, caused by something blocking or narrowing a blood vessel.
Etymology
Taken from New Latin ischaemia, itself from Ancient Greek ἴσχαιμος (ískhaimos, “stoppage of blood flow”), formed from ῐ̓́σχω (ĭ́skhō, “to hold back, restrain; to stay, stop”) and αἷμᾰ (haîmă, “blood”). The plural, ischemiae, likewise comes from New Latin ischaemiae.
