In this lesson, we look at the cardiovascular system. In the first section, we look at the heart and its structure and function. In addition to the various anatomical structures of the heart and its immediate surroundings, you will also learn about the supply of nutrients and oxygen to the heart muscle. In terms of physiology, we look at the individual phases of the cardiac cycle, including the development of excitation of the heart muscle, which we can read in electrocardiography.
The circulatory system and its vessels are closely linked to the heart. We will take a closer look at the structure and differences between arteries, veins and capillaries and also clarify their influence on blood pressure and blood flow. We will also look at the exchange of substances between the capillary system and the surrounding tissue. You will learn about the structure and function of the lymphatic system and understand how dysfunctions can occur here. A portal vein system is a special variant within the vascular system, which we will take a closer look at using the liver as an example. Indirect blood pressure and pulse measurements are standard clinical examinations. In this lesson, you will learn the theoretical basis for correct measurements.
Finally, we will visit a patient in the emergency room - there is no time to lose here. As we are of course only doing this virtually, you can work through this chapter at your leisure.
