In this stage of shock, perfusion is reduced to essential tissues, such as the brain and heart. widespread cellular hypoxia and anaerobic metabolism occur?

Irreversible.

Explanation:

Shock may be defined as the medical condition in which the there is deficiency in the blood flow to the oxygen and tissue of the body. The waste products start building in the organ.

Three main stages of the shock are initial, progressive and irreversible. The stage III or irreversible shock includes the anaerobic condition in the brain and the anaerobic metabolism starts in the body.

Thus, the correct answer is irreversible.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
