Where is the human heart really located?
It lies in the front and middle of your chest, behind and slightly to the left of your breastbone. It is a muscle that pumps blood to all parts of your body to provide it with the oxygen and nutrients in needs to function. Your heart has the right and left separated by a wall.
Where is the apex of the heart found?
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.
What is the physiological function of the heart?
The four main functions of the heart are: Pumping oxygenated blood to the other body parts. Pumping hormones and other vital substances to different parts of the body. Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
Which side of the heart is more muscular?
left ventricle
The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as seen in the adjacent image.
Where is the heart located on a woman?
The heart is in the chest, slightly left of center. It sits behind the breastbone and between the lungs. The heart has four distinct chambers.
What side is a woman’s heart on?
Chest pain is the most common heart attack symptom, but some women may experience it differently than men. It may feel like a squeezing or fullness, and the pain can be anywhere in the chest, not just on the left side.

What is the apex beat of the heart?
The apex is the tip or summit of an organ; the apex beat is the heart’s impact against the chest wall during systole. It is primarily due to recoil of the apex of the heart as blood is expelled during systole and correlates with left ventricular contraction (Scott and MacInnes, 2006).
What are 3 layers of the heart?
The walls of the heart are composed of three layers:
- Epicardium – the outer layer.
- Myocardium – the middle, muscular layer.
- Endocardium – the inner layer.
What is the main function of heart?
It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.
Why is the left side of the heart so muscular?
The reason for this difference in muscle size is because the left ventricle needs to pump blood to the whole body, compared to the right ventricle which only pumps blood to the lungs. The larger muscle size is needed to generate the force necessary to pump the blood to the whole body.
Why the left side of the heart is more muscular?
The left ventricle of the heart is more muscular than the right ventricle because the left ventricle has to pump blood a longer distance than the right ventricle. This makes the heart incredibly efficient because it prevents oxygen poor blood from mixing with oxygen rich blood.
