Question

Name the organ which is located in the chest cavity with its lower tip slightly tilted towards the left.

Answer 1

Hint: The thoracic cavity is also known as the chest cavity. It is a hollow space in the human body. The chest cavity is protected by the thoracic wall. The thoracic wall is made up of the rib cage, muscle, and fascia. The organs present in the chest cavity are the thymus gland, the heart, and the lungs.

Complete answer:
The heart is the organ that pumps blood to all parts of the body. It is about the size of a fist and the weight is around two eighty to three forty grams in men and two-thirty to two eighty grams in women. The heart is located between the lungs in the chest cavity. This area is known as the mediastinum. The base of the heart, which is cone-shaped, is at the top, behind the sternum. The larger vessels either enter or leave here. The tip of the heart (apex points down and slightly to the left. Since it is pointed to the left, the heartbeat can be felt on the left side, as the strongest beat can be felt at the tip.

The heart wall is made up of three layers. The outermost layer is known as the epicardium. It is made up of a thin-layered membrane that helps to lubricate and acts as a protection to the outer part.
The middle layer is known as the myocardium. It is the thick muscular layer and is responsible for the pumping of the heart.

The innermost layer is called the endocardium. It covers the inner part of the heart chambers and the valves. It prevents blood from sticking to the inner heart surface.

Note: The heart valves are flaps of fibrous tissues. They are found between the veins in the heart chambers. Their function is to ensure the unidirectional flow of blood. The different heart valves that are present in the human heart are the tricuspid valve, the mitral valve, and the semilunar valve.
