| Afterload | The force resistance against which the heart pumps. |
| Anaphylactic Shock | Severe shockl caused by allergic reactiions |
| Anaphylaxis | An unusual or exaggerated allergic reaction to a foreign protein or other substance. |
| Anuerysm | A swelling or enlargement of a part of an artery resulting from weakening of the arterial wall. |
| Autonomic Nervous System | The part of the nervous system that regulates involuntary functions, such as heart rate, blood pressure, digestion, and swelling. |
| Cardiogenic Shock | Shock caused by inadequate function of the heart, or pump failure. |
| Compensated Shock | The early stage of shock, in which the body can still compensate for blood loss |
| Cyanosis | Bluish color of the skin resulting from poor oxygenation of the circulating blood. |
| Decompensated Shock | The late stage of shock when blood pressure is falling. |
| Dehydration | Loss of water from the tissues of the body. |
| Distributive Shock | A condition that occurs when there is widespread dilation of the small arterioles, small venules, or both. |
| Edema | The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area. |
| Homeostasis | A balance of all systems of the body. |
| Hypothermia | A condition in which the internal body temperature falls below 95-F (35-C) degrees, usually the result of prolonged exposure to cool or freezing temperatures. |
| Hypovolemic Shock | Shock caused by fluid or blood loss. |
| Irreversible Shock | The final stage of shock, resulting in death. |
| Myocardial Contractility | The ability of the heart muscle to contract. |
| Neurogenic Shock | Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in patients with spinal cord injuries. |
| Obstructive Shock | Shock that occurs when there is a block to blood flood flow in the heasrt or great vessels,causing an insufficient blood supply to the body's tissues. |
| Perfusion | Circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs. |
| Preload | The pre-contraction pressure in the heartas the volume of blood builds up. |
| Psychogenic Shock | Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope). |
| Sensitization | Developing a sensitivity to a substance that initially caused no allergic reaction. |
| Septic Shock | Shock caused by severe infection, usually a bacterial infection. |
| Shock | A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function, also called "hypoperfusion". |
| Sphincters | Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening. |
| Syncope | Fainting |
