Location: The lateral wall is generally considered to include the wall of the right atrium from the ostia of the superior and inferior vena cava anteriorly to the ostium of the right appendage or auricle.
What is a lateral view of the heart?
Heart Lateral View
Represented in the image with the heart are the aortic arch (cut), the vena cava and the pulmonary trunk. The sagittal section of this heart provides an informative view of the inside of the left ventricle and atrium.
Where is the lateral wall of the left ventricle located?
It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve. As the heart contracts, blood eventually flows back into the left atrium, and then through the mitral valve, whereupon it next enters the left ventricle.
What is the anterior part of the heart?
Anteriorly are the right atrial appendage, the right ventricular outflow tract and the pulmonary trunk. The transverse pericardial sinus separates the back of the aorta from the left atrium and right pulmonary artery.
What are the 4 surfaces of the heart?
The heart has four surfaces:
- Sternocostal surface: The anterior portion formed mostly by the right ventricle.
- Diaphragmatic surface: The inferior portion formed by the left ventricle and part of the right ventricle.
- Left pulmonary surface: Made up of the surface of the left ventricle.
Why do we perform a left lateral chest radiograph rather than a right lateral?
The most commonly cited reason for favoring the left rather than right lateral chest radiograph is that the left-sided cardiac structures are closer to the film and less magnified.
What does lateral view mean?
Denoting a position farther from the median plane or midline of the body of a surface; pertaining to a side.
What is the function of left ventricle?
The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Is lateral to left ventricle?
Anatomical terms of neuroanatomy
The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively.
Where does blood go when it leaves the left ventricle?
This is the muscular pump that sends blood out to the rest of the body. When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body’s tissues.
Are the lungs lateral to the heart?
The lungs lie lateral to the heart. … The heart lies medial to the lungs.
What part of heart is most anterior?
The right ventricle (RV) is the most anterior of the four heart chambers.
What does anterior mean?
1a : situated before or toward the front an anterior ligament. b : situated near or toward the head or part most nearly corresponding to a head.
Is the heart base up or down?
The base of the heart is located at the level of the third costal cartilage, as seen in Figure 1. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages.
What is apex and base of heart?
The apex (the most inferior, anterior, and lateral part as the heart lies in situ) is located on the midclavicular line, in the fifth intercostal space. It is formed by the left ventricle. The base of the heart, the posterior part, is formed by both atria, but mainly the left.
What divides the left and right side of the heart?
septum (SEP-tum): The septum is a thick wall of muscle that divides the heart. It separates the left and right sides of the heart.
