- The heart consists of several layers of a tough muscular wall, the myocardium. A thin layer of tissue, the pericardium, covers the outside, and another layer, the endocardium, lines the inside. The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers.

Nov 10, 2024 · The heart is a four-chambered muscular organ with a complex structure that allows it to efficiently pump blood throughout the body. It is divided into two halves—the right and left sides—each responsible for different aspects of circulation. The heart consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle.

The parts of your heart are like the parts of a building. Your heart anatomy includes: 1. Walls. 2. Chambers that are like rooms. 3. Valvesthat open and close like doors to the rooms. 4. Blood vesselslike plumbing pipes that run through a building. 5. An electrical conduction systemlike electrical power that runs through a building.
Your heart is in the front of your chest. It sits slightly behind and to the left of your sternum (breastbone), which is in the middle of your chest. Your heart is slightly on the left side of your body. It sits between your right and left lungs. The left lung is slightly smaller to make room for the heart in your left chest. Your rib cage protects...
Your heart looks a little bit like an upside-down pyramid with rounded edges. Large blood vessels go into and out of your heart to bring blood into and away from your heart. They connect your heart to the rest of your body, which it supplies with blood and oxygen.
The heart has four chambers: the left and right atriums and the left and right ventricles. They form a shallow groove at the line of their junction, which form the atrioventricular groove. The atrioventricular groove hosts major coronary arteries while they travel along to the line of attachment of atrioventricular valves.

- Heart Anatomy. The heart is made up of four chambers: Atria: Upper two chambers of the heart. Ventricles: Lower two chambers of the heart.
- Heart Wall. The heart wall consists of three layers: Epicardium: The outer layer of the wall of the heart. Myocardium: The muscular middle layer of the wall of the heart.
- Cardiac Conduction. Cardiac conduction is the rate at which the heart conducts electrical impulses. Heart nodes and nerve fibers play an important role in causing the heart to contract.
- Cardiac Cycle. The Cardiac cycle is the sequence of events that occurs when the heart beats. Below are the two phases of the cardiac cycle: Diastole phase: The heart ventricles are relaxed and the heart fills with blood.
The heart is divided into four chambers: right atrium, right ventricle, left atrium, and left ventricle. The atria are the two superior chambers of the heart and the ventricles are the two inferior chambers of the heart.
Feb 27, 2019 · The outer layer of the pericardium surrounds the roots of the heart's major blood vessels, and the inner layer is attached to the heart muscle. Your heart does a lot of work to keep the body going. Learn about the organ’s amazing power and the functions of its many parts.
