Cardiovascular Essentials for Medical Assistants-Video: Cardiovascular Anatomy and Physiology

Video Transcription

Video Summary

In this video, the speaker covers the cardiac anatomy and physiology. They begin by explaining the different chambers of the heart, including the atria and ventricles, and the septum that separates them. They then discuss the valves of the heart, which act as doors opening and closing to allow blood flow. The speaker explains the different valves and their locations. Moving on to cardiac physiology, they describe the heart as a pump that moves blood through the body. They discuss the flow of blood through the heart, including the right and left sides, and the pre-lungs and post-lungs circuits. The speaker explains the concept of systolic and diastolic dysfunction, which refer to abnormal contraction and relaxation of the heart muscle. They also cover ejection fraction, which is the percentage of blood emptied from the left ventricle during contraction. The speaker then discusses valve abnormalities, such as stenosis and regurgitation, as well as the importance of the electrical pathway in the heart. They describe the normal conduction pathway and how abnormalities in this pathway can lead to abnormal heart rhythms. The speaker concludes by mentioning that the information covered is important for understanding diseases and patient management in clinical practice. No credits were mentioned in the video.
