An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The compressor, the âheartâ of the carâs air conditioning system works like a pump taking refrigerant, (R-12 in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. The AC compressor has several moving parts (including pistons and valves).
Quick Answer. According to WebMD, a normal blood pressure is lower than 120/80. This means that the systolic number is 120 or lower, and the diastolic number is 80 or lower. The systolic number measures artery pressure when the heart contracts. The diastolic number measures artery pressure between heartbeats.

Blood sugar levels after a meal (non-fasting) should only rise 40 mg/dL over your fasting level. This means that your blood sugar level should be in the range of 110â125mg/dL one or two hours after a meal.
