In this activity, students will learn to correctly label the following external anatomy of the anterior human heart. They will understand the function of the internal and external arteries that carry blood throughout the body. The aortic sinus body and the thoracic cage also play a role in the circulatory system. The right atrium, the anterior descending aorta, and the vasculature are all essential organs of the cardiovascular system.
The external anatomy of the human heart consists of the four chambers that form the apex of the heart. Each chamber has an apex that corresponds to a box. There are two boxes on each side of the heart: the atria and the ventricles. The left atrium is a branching organ. The pulmonary trunk contains the aorta and pulmonary veins.
Using your knowledge of the human heart, you can also label the various arteries that lead to the heart. The anterior interventricular artery is the largest artery, and branches out from the left atrium. The left marginal artery is located at the top of the right auricle. The inferior vena cava is the largest artery. The aortic ostium is the lower part of the aorta, which is located in the chest.
The left atrium is the apex of the heart, while the right atrium is the left atrium. The ventricles are called the aorta and pulmonary artery. In between these two cavities is a vein known as the aortic apex. The two coronary arteries are separated by the superior vena cava. When the blood flows to the left atrium, it exits through the aortic arch, the inferior vena cava is named the aortic sinus.
The right atrium and the left ventricle are connected by a network of veins. The aorta is the apex of the heart. The aortic sinus is the apex of the cardiac arteries. The coronary artery is the large, thin vein that drains the right atrium. The small aortic artery drains the left atrium.
The anterior aortic sinus is the location of the aortic artery. Its terminal parts include the right atrium, the posterior aortic sinus, and the aortic artery. The remaining parts are the aortic valve and the aortic arteries. The aortic artery is located at the base of the aortic sinus.
The anterior interventricular artery, also known as the AIVA, is located at the left aortic sinus. It is the main artery that connects the right aortic auricle to the aorta. The two auricles are connected by the aortic artery and the pulmonary trunk. The pulmonary auricle is located in the right atrium. The superior vena cava is located at the bottom of the aortic sinus.
The apex of the heart is formed by the left atrium and the left ventricle. The aortic sinus is the location of the aortic artery. The apex of the heart is surrounded by the aortic artery. The left aortic sinus and the pulmonary auricle are connected by the aortic aorta.
The apex of the heart consists of the atria and the two ventricles. These chambers are separated by the aortic sinus and the aortic artery. The atria and ventricles are joined by the coronary artery. These arteries are connected to the apex of the heart by a ring. It is not necessary to draw the apex of the aortic sinus.
The right atrium has four chambers, known as atria. These chambers are connected by a narrow opening called the coronary sinus. The left atrium has a heart that is deflected posteriorly. The atria is deflected anteriorly. The aortic arch is the aortic apex. The atria and aortic arch are separated by the atrioventricular sulcus.
