Its quantity may be increased (hyperemia or polyhzemia) or diminished (ansemia or hypzemia). This increase or diminu- tion may either be general, extending to the whole organism, or local, and restricted to particular parts of the body. 3. It may be effused in consequence of laceration of the blood-vessels, into the interstices of the parenchyma of certain organs, or into some of the cavities of the body, con- stituting extravasation. 4. The hematin may, by a process of decomposition, be- come: dissolved, and then be imbibed by the tissues. ‘l;, PHYSICAL AND CHEMICAL CHANGES OF THE BLOOD.
