The human heart is a four-chambered muscular organ, shaped and sized roughly like a man’s closed fist with two-thirds of the mass to the left of midline. The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane.
Subsequently, What are the main parts of 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.
Also, What is the function of the heart?
Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.
What is the heart structure and function?
The heart is a large muscular pump and is divided into two halves – the right-hand side and the left-hand side. The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs. The left-hand side pumps oxygenated blood around the body.

– Maintaining blood pressure.
Where exactly is your heart located?

What is the main structure of the heart?
The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.
What are the 3 main functions of the heart?

What is heart and its function and structure?
The heart is a muscle whose working mechanism is made possible by the many parts that operate together. The organ is divided into several chambers that take in and distribute oxygen-poor or oxygen-rich blood. These chambers are accompanied by veins and arteries that facilitate the same function.
What is the heart’s main function?
The task of your heart is to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain and the other vital organs.
What are the parts of the heart and its functions?
– The right atrium receives blood from the veins and pumps it to the right ventricle.
– The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.
– The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

What are the parts of the heart?
– The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.
– The two top chambers are the right atrium and the left atrium. They receive the blood entering the heart.
