The official world record for the longest hair is held by Xie Qiuping of China, whose hair was measured in 2004 at 4.2 meters (14 ft) long.

The lungs are among the hardest-working organs in the body. They expand and contract up to 20 times a minute to supply oxygen to be distributed to tissues all over the body and expel carbon dioxide that has been created throughout the body.

In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The study of tissue is known as histology or, in connection with disease, histopathology.
