A mass airflow sensor. A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure.
Over time, scar tissue that forms from bleeding can cause the retina to detach from the wall of the eye (retinal detachment) and cause loss of vision. Severe proliferative retinopathy may be treated with laser surgery in order to save vision.
The eye has a red spot of blood on the sclera (the white part of the eye). This occurs when there is a rupture of a small blood vessel on the surface of the eye.
