The thorax or chest is a part of the anatomy of humans, mammals, other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the creature's body, each of which is in turn composed of multiple segments. 胸部是人类、哺乳动物和其他四足动物的解剖结构的一部分，位于颈部和腹部之间。在昆虫、甲壳类动物和已灭绝的三叶虫中，胸部是生物身体的三个主要部分之一，每个部分又由多个部分组成。

The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain. 人的胸部包括胸腔和胸壁。它包括心脏、肺、胸腺等器官，以及肌肉和各种其他内部结构。许多疾病可能影响胸部，其中最常见的症状之一是胸痛。

In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle. 在人类和其他原始人类中，胸部是身体颈部和腹部之间的胸部区域，以及内部器官和其他内容物。它主要由胸腔、脊柱和肩带保护和支撑。[原始的肩带只是一个软骨棒，以后逐渐发展骨化成硬骨。]

The ribs of the thorax are numbered in ascending order from 1-12. 11 & 12 are known as floating ribs because they have no anterior attachment point in particular the cartilage attached to the sternum, as 1-7 are, and therefore are termed "floating". 胸部肋骨按1-12的升序编号。11和12被称为浮动肋骨，因为它们没有前附着点，尤其是与胸骨相连的软骨，如1-7，因此被称为“浮动”。

Pectus carinatum is a rare chest wall deformity that causes the breastbone to push outward instead of being flush [完全平齐的] against the chest. It is also known as pigeon chest [鸡胸] or keel chest. When the chest wall develops, the cartilage that connects the ribs usually grows flat along the chest.
