Path from femoral vein to the lower lobe of right lung
In addition to these shared functions, many systems enjoy a unique relationship with the circulatory system.
The right coronary artery arises from the anterior aortic sinus. Another phenomenon that can make the study of vessels challenging is that names of vessels can change with location.
Once in the lungs, go to the lower lobe of the right lung. Moreover, some superficial veins, such as the great saphenous vein in the femoral region, have no arterial counterpart. Both the carotid and vertebral arteries branch once they enter the cranial cavity, and some of these branches form a structure known as the arterial circle or circle of Willisan anastomosis that is remarkably like a traffic circle that sends off branches in this case, arterial branches to the brain.
The inferior vena cava receives a vein directly from the
These sinuses contain the aortic baroreceptors and chemoreceptors critical to maintain cardiac function. International Conferences Merge this question into Split and merge into it SAVE In Arteries From the Femoral vein, you would go to the inferior vena cava, which then leads to the right atrium of the heart. You might envision being inside a miniature boat, exploring the various branches of the circulatory system. However, we will attempt to discuss the major pathways for blood and acquaint you with the major named arteries and veins in the body. See Figure 4 for an illustration of the ascending aorta, the aortic arch, and the initial segment of the descending aorta plus major branches; Table 5 summarizes the structures of the aorta. How do you trace the path of a catheter from right femoral artery to the left coronary artery? Blood flow goes as follows: Circle of Willis What is unique about the pulmonary arteries and pulmonary veins? This is an example of an anastomosis. The left lobe only has two. Blood returns via the pulmonary veins to the left atrium. The structure is referred to as the arterial circle or circle of Willis. This simple approach has proven effective for many students in mastering these major circulatory patterns. The subclavian artery also gives rise to the thyrocervical artery that provides blood to the thyroid, the cervical region of the neck, and the upper back and shoulder. Interaction of the Circulatory System with Other Body Systems As you learn about the vessels of the systemic and pulmonary circuits, notice that many arteries and veins share the same names, parallel one another throughout the body, and are very similar on the right and left sides of the body. Recall that blood flow to the brain is remarkably constant, with approximately 20 percent of blood flow directed to this organ at any given time.
This system of vessels is referred to as the pulmonary circuit. Figure 1 summarizes these relationships. Chapter From the left atrium, blood moves into the left ventricle, which pumps blood into the aorta. You might envision being inside a miniature boat, exploring the various branches of the circulatory system.
