- Draw a tilted and irregular curved shape in the center of your page. Use a pen or pencil to draw the heart's main body. Create a curved shape similar to an acorn or apple’s bottom half. Angle the slightly tampered end of the shape to the left about 120 degrees. The main shape will be the basis for the left and right ventricles.

Oct 20, 2024 · The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure \(\PageIndex{1}\).

The heart sits within a fluid-filled cavity called the pericardial cavity. The walls and lining of the pericardial cavity are a special membrane known as the pericardium. Pericardium is a type of serous membrane that produces serous fluid to lubricate the heart and prevent friction between the ever beating heart and its surrounding organs. Besides ...
The heart wall is made of 3 layers: epicardium, myocardium and endocardium. 1. Epicardium. The epicardium is the outermost layer of the heart wall and is just another name for the visceral layer of the pericardium. Thus, the epicardium is a thin layer of serous membrane that helps to lubricate and protect the outside of the heart. Below the epicard...
The heart contains 4 chambers: the right atrium, left atrium, right ventricle, and left ventricle. The atria are smaller than the ventricles and have thinner, less muscular walls than the ventricles. The atria act as receiving chambers for blood, so they are connected to the veins that carry blood to the heart. The ventricles are the larger, strong...
The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or "regurgitating" back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves. 1. Atrioventricular valves. The atriove...
The heart is able to both set its own rhythm and to conduct the signals necessary to maintain and coordinate this rhythm throughout its structures. About 1% of the cardiac muscle cells in the heart are responsible for forming the conduction system that sets the pace for the rest of the cardiac muscle cells. The conduction system starts with the pac...
The space bound by the IVC and the right pulmonary veins (in the lower part of the image) and the left pulmonary veins, is the oblique sinus of pericardium. Before the heart was removed, my fingers could trace the cul de sac! The left atrium, occupying most of this space forms the base of the heart.
In this tutorial, we will guide you through the process of drawing the structure of the human heart, including the chambers, valves, arteries, and veins. Wit...

The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure 1.
Jun 20, 2023 · To draw the internal structure of the heart, start by sketching the 2 pulmonary veins to the lower left of the aorta and the bottom of the inferior vena cava slightly to the right of that. Then, fill in the base of the heart with the right and left ventricles and the right and left atriums.
