Select the three basic ways in which microbes cause tissue damage

The three basic ways in which microbes cause tissue damage are the following;

·         It activates the response of host in which is self-destructive to the host tissues

·         It causes tissue damage by releasing toxins

·         The breakdown of host tissues are caused by enzymes in which are being released

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
