The interior of the heart is divided into four separate chambers.

The heart for dummies. The right side of your heart receives blood from the body and pumps it to the lungs. The deep cardiac plexus is located on the bifurcation of the trachea and the superficial cardiac plexus is located on the base of the heart below the arch of the aorta. In addition the blood vessels constrict raising blood pressure.

It also carries away waste. The right atrium receives venous blood from the superior vena cava inferior. The heart the main organ of the circulatory system causes blood to flow.

Asystole is simply when the heart is no longer generating any electrical impulses. Two ventricles each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels and two atria each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The heart is innervated by the autonomic nerves from superficial and deep cardiac plexuses.

These impulses cause the heart to contract and then relax. The blood provides your body with the oxygen and nutrients it needs. It is represented by a simple flat line on the ecg.

Occasionally a wide pulseless wave form will appear at random known as an agonal complex. Cardiac conduction is the rate at which the heart conducts electrical impulses. The heart s pumping action squeezes blood out of the heart and the pressure it generates forces the blood through the blood vessels.

The heart sends blood around your body. Cpr and acls medication are required for a chance at survival. The two ventricles are at the bottom.

The heart s job is to pump blood to the lungs to get oxygen and to pump the oxygenated blood to the rest of the body. This makes it even harder for the heart to push blood through the arteries. Because the body is retaining salt and water or the heart is unable to pump blood forward water may pool in the legs and ankles causing them to swell.

The constant cycle of heart muscle contraction followed by relaxation causes blood to be pumped throughout the body.
