Structures of the cardiovascular system

The pericardiumIs the walled membranous sac that encloses the heart.

The walls of the heartThe walls of the heart are made up of three layers

Epicardium: it is the external layer of the heart also is part of the inner layer of the pericardium.

Myocardium: it is the middle and thickest of the three layers consist of cardiac muscle.

Endocardium:It is lining of the heart, from the inner surface of the heart.

The blood vessels:There are three major types of blood vessels in the body these are the:

The arteriesThe arteries are the large blood vessels that carry blood away from the heart to all the body. It is the high oxygen blood

1- Angiocardiograpy

Angio------- means blood vesselCardio------ means heartGrapy------ means the process of recording

2- Cardiac catheterization (C.C) it is a procedure in which a catheter is pulled into a vein or artery and is guided into the heart

3- Electrocardiogram (E.C.G) or (E.K.G) is a record of the electrical activity of the myocardium

Diagnostic procedures of the cardiovascular system (Con)

•Defibrillation:Is the use of electrical shock to restore the heart normal. Rhythm this can be performed extremely as an emergency procedure or a device may be implanted to control severe arrhythmias

Medical terms related to the cardiovascular system

•A pacemaker: Is an electronic device that may be attached externally or implanted under the skin, with connections leading into the heart to regulate the heart beat. Pacemaker is used as treatment for brady cardia or arterial fibrillation.

Medical terms related to the cardiovascular system

•An atherosclerosis: is hardening and narrowing of the arteries.

•Ischemic heart disease (I.H.D.) - Means insufficient supply of oxygenated blood to heart.

angina pectoris: is a sever episode of is a clinical syndrome characterized by pain or feeling of pressure in the anterior chest when body is not receiving adequate oxygen

Medical terms related to the cardiovascular system

Medical terms related to the cardiovascular system

• Myocardial infarction: (heart attack) when blood supply to heart is completely blocked; muscle dies

• hypertension : high blood pressure• Congestive heart failure: Inability of the heart to

pump its required amount of blood. Blood accumulates in the lungs, causing pulmonary edema.

• Tachycardia: Condition of fast, rapid heartbeat• Bradycardia: slow heartbeat
