Final answer:
The statement is true; the xiphoid process is indeed located at the lower end of the sternum.
Step-by-step explanation:
True, the xiphoid process is located at the lower end of the sternum. The sternum, also known as the breastbone, consists of three parts: the manubrium, body, and xiphoid process. The manubrium is the upper portion, while the xiphoid process forms the smallest, most inferior part. Initially cartilaginous, the xiphoid process undergoes ossification starting during middle age, turning into bone. The ribs connect to the thoracic vertebrae at the back and most of them attach anteriorly to the sternum via their costal cartilages, forming the front part of the thoracic cage.
