Embolism is a sudden occlusion of a blood vessel by a small body traveling in the circulatory system.

A strong organism is not given to gathering moss, so to speak, as we see in the case of the old oaken bucket. However, there is a very strong tendency for the development of emboli from deposits taking place in the heart, on the valves of the heart, and in the blood vessels, when there has been toxin infection running on for years. This occurs when the blood fails to carry a normal amount of enzymes.

A normal blood digests all clots which form from whatever cause. When foreign bodies succeed in gaining entrance into the circulation, they must be very resistant if they are not digested and made a part of the blood. The same is true of the lymphatic circulation. The lymphatic glands have the power of benevolently assimilating toxins that are absorbed.

Emboli are divided into exogenous and endogeenous--those entering the body and those developed in the body.

Endocarditis ends in atheromatous productions which open into the general circulation. The same occurs in arteritis. This accounts for many sudden and unexpected deaths.

Blood clots form on the interior of the blood vessels. They are caused by injury and various diseased conditions. Inflammation of the aorta may at almost any time furnish an embolus. that will swing into the circulation and cause a fatal obstruction.

Inflammation of veins is very liable to cause emboli. Phlebitis is caused by infection, This disease is very prone to cause embolism. It should never be forgotten that, if it were not for man's great immunizing power, he would be unable to protect himself against the many invasions of his organism.

Course of Emboli: Emboli follow a regular route. Those of the arteries start from a lesion of the pulmonary veins, of the left heart, or of the aorta. They pass into the left carotid. They stop at the sylvian, and produce hemiplegia with aphasia. The embolus may follow the aorta, and may stop in the splenic, the renal, or the iliac arteries.

Effects of Embolism: Arrest may be in the heart. In this case sudden death may occur. A reflex syncope is produced, due to the excitation of the endocardium.

Pulmonary apoplexy may be caused by an embolus.

Softening is a common effect of embolism. Apoplexy is another effect.

When emboli are very small, only headache, dizziness, or some mental disturbance may result.

Partial or complete blindness may result from embolism of the central artery of the retina.

There are fatty and gaseous emboli.
