No, the heart is placed more towards the left lung, anterior to the vertebral column and posterior to the sternum.
That is why in 95% of the world population there are only two lobes on the left lung and three on the right.
The heart is located in the thoracic cavity, specifically in the mediastinum, situated between the lungs.
Heart is located in the thoracic cavity and the appendix is in the abdominal cavity.
The body cavity bounded by the ribs is the thoracic cavity. It contains the heart, lungs, and other structures involved in breathing and circulation.

thoracic cavity
The heart is located in a small cavity called the mediastinum, which is situated in the thoracic cavity between the lungs. Specifically, it is positioned in the middle mediastinum, bordered by the sternum in front and the vertebral column behind. This space contains not only the heart but also major blood vessels, the trachea, and other structures.
Chest cavity
The thoracic cavity contains the heart and lungs, while the abdominal cavity houses the digestive organs such as the stomach, liver, and intestines. The thoracic cavity is separated from the abdominal cavity by the diaphragm muscle. The thoracic cavity is enclosed by the rib cage, while the abdominal cavity is not.
The chest cavity is a general term referring to the area within the chest, while the thoracic cavity specifically refers to the space within the rib cage that contains the lungs and heart. The thoracic cavity is a subset of the overall chest cavity.
The heart is a vital organ located in the thoracic cavity, between the lungs. It is responsible for pumping blood throughout the body, delivering oxygen and nutrients to cells and removing waste products.
Organs like the heart and lungs are not found in the abdominal cavity. The heart is located in the thoracic cavity, between the two lungs, while the lungs are also located in the thoracic cavity on either side of the heart.
The mediastinum contains the heart and its large vessels, the trachea, thymus, lymph nodes, aorta, esophagus and bronchi. It is divided into superior and inferior regions, the latter subdivided into anterior, middle, and posterior parts.
