1. Identify the right and left sides of the heart. Look closely and on one side you will see a diagonal line of blood vessels that divide the heart, this line is called the interventricular sulcus. The half that includes all of the apex (pointed end) of the heart is the left side.
What is the pointy end of the heart called?
The apex is the pointed tip of the heart. It is located on the lower portion of the heart (left ventricle).
What are the different parts of the heart?
Heart Chambers, Valves, Vessels, Wall and Conduction System
The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.
What does the apex of the heart do?
The heart sits atop the diaphragm and its apex is close to the anterior surface of the thoracic cavity. With every beat, the heart twists forward and the apex taps against the chest wall, producing the apex beat.
Where is the apex of the heart located?
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.
Which heart chamber has the thickest walls?
The left ventricle of your heart is larger and thicker than the right ventricle. This is because it has to pump the blood further around the body, and against higher pressure, compared with the right ventricle.
Which are the strongest pumping chambers?
The left and right ventricles are stronger pumps. The left ventricle is the strongest because it has to pump blood out to the entire body. When your heart functions normally, all four chambers work together in a continuous and coordinated effort to keep oxygen-rich blood circulating throughout your body.

What are the 4 layers of the heart?
The outer layer of the heart wall is the epicardium, the middle layer is the myocardium, and the inner layer is the endocardium.
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.
What is the largest vein in the human body?
The inferior vena cava (or caudal vena cava in some animals) travels up alongside the abdominal aorta with blood from the lower part of the body. It is the largest vein in the human body.
What is a pericardium?
Summary. The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include.
What side is the human heart?
The base of the heart is located along the body’s midline with the apex pointing toward the left side. Because the heart points to the left, about 2/3 of the heart’s mass is found on the left side of the body and the other 1/3 is on the right.
What are the heart layers?
The walls of the heart are composed of three layers:
- Epicardium – the outer layer.
- Myocardium – the middle, muscular layer.
- Endocardium – the inner layer.
Are the lungs lateral to the heart?
The lungs lie lateral to the heart. … The heart lies medial to the lungs.
