CaseThe body of a man was found floating in the

saltwater Bay, which has a concentration that is slightly greater than body fluids. When seen during the autopsy the cell in his lung tissues were clearly swollen. Choose the most logical conclusion

A. He probably drowned in the bay.B. He may have been murdered elsewhere.C. He did not drown.

Active TransportMovement of molecules from an area of lower concentration to an area of lower concentration with the aid of carrier proteins. It requires energy.

Sodium Potassium Pump

EndocytosisThe bulk movement of materials into a cell by the formation of a vesicle.

PinocytosisUptake of small droplets of extracellular fluid.

Receptor-Mediated EndocytosisA specific receptor protein binds with an extracellular molecule before digestion.

PhagocytosisUptake of solid particles.

ExocytosisMovement of material outside the cell from inside.
