Superficial muscles of the chest and upper arm in humans

The chest ( Latin pectus , adjective pectoralis ) is the front half of the trunk in vertebrates , and the upper part of the trunk in upright humans .

The bony basis of the chest is the chest ( thorax ), which surrounds the chest cavity ( cavum thoracis ) with the organs located in it . The thorax consists of the thoracic spine , the ribs ( costae ) and the breastbone ( sternum ). The largest muscle in the chest is the pectoralis major muscle . The lymphatic drainage from the breast occurs mainly through the axillary lymph nodes .

The term "breast" is also used for the breast with the mammary gland ( mamma ). The arrangement of the mammary gland ( glandula mammaria ) in the breast area is only typical for a few mammals . The lungs and deep airways are also sometimes referred to as the chest.
