Ex Input:
The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity. In humans, the blood -- brain barrier, blood -- cerebrospinal fluid barrier, and similar fluid -- brain barriers separate the peripheral immune system from the neuroimmune system, which protects the brain.

Ex Output:
how many immune systems does the body have


Ex Input:
The Sino-Tibetan languages, in a few sources also known as Trans-Himalayan, are a family of more than 400 languages spoken in East Asia, Southeast Asia and South Asia. The family is second only to Indo-European in terms of the number of native speakers. The Sino-Tibetan languages with the most native speakers are the varieties of Chinese (1.3 billion speakers), Burmese (33 million), and the Tibetic languages (6 million), but many Sino-Tibetan languages are spoken by small communities in remote mountain areas and as such are poorly documented. Unlike Western linguists, Chinese linguists generally include Kra -- Dai and Hmong-Mien languages within Sino-Tibetan.
