Study Notes
Cardiovascular System Anatomy & Physiology
- Structures include the heart and blood vessels.
- Components include layers, chambers, great vessels, valves, blood vessels, and the conduction system.
- The cardiovascular system manages blood supply, produces blood pressure, ensures one-way flow, and transmits blood.
Alterations in Perfusion
- Low blood pressure (BP) can lead to poor tissue perfusion and shock.
- Hypotension is a late sign of compromise.
- Care and treatment should begin before hypotension develops.
- Hypertension is often underdiagnosed and can lead to poor health outcomes.
Shock
- A critical condition caused by a sudden drop in blood flow throughout the body.
- May result from trauma, heatstroke, blood loss, or an allergic reaction.
Anatomy and Physiology of Cardiovascular System
- Structures include the heart and blood vessels
- Layers: Endocardium, myocardium, epicardium
- Chambers: Right atrium, right ventricle, left atrium, left ventricle
- Great Vessels: Aorta, pulmonary artery, superior vena cava, inferior vena cava
- Valves: Atrioventricular valves (tricuspid and mitral), semilunar valves (pulmonary and aortic)
- Blood Vessels: Arteries, veins, capillaries
- Conduction System: Sinoatrial node (SA node), atrioventricular node (AV node), bundle of His, Purkinje fibers
- Functions:
- Managing blood supply to the body
- Producing blood pressure to pump blood throughout the body
- Securing one-way flow of blood through the heart and circulatory system
- Transmitting blood from the heart to the rest of the body
Alterations in Perfusion
- Low blood pressure (BP) can lead to poor tissue perfusion and shock.
- Hypotension is a LATE sign of circulatory compromise, meaning that treatment should begin before hypotension occurs.
- Hypertension is often underdiagnosed and can lead to poor health outcomes.
- Shock is a critical condition due to a sudden drop in blood flow through the body.
- Causes: Trauma, heatstroke, blood loss, allergic reaction.
