Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.
The Largest Gas Producing province of Pakistan is Baluchistan. The Sui gas field is the biggest natural gas field in Pakistan. It is near Sui in Balochistan. The gas field was discovered in the late 1952 and the commercial exploitation of the field began in 1955. Sui gas field accounts for 6% of Pakistan's gas production. [14]
[9] Pakistan's first gas field was the giant gas field at Sui in Balochistan which was discovered in the late 1952. [10] Pakistan is also a major producer of bituminous coal, sub-bituminous coal and lignite. Coal mining started in the British colonial era and has continued to be used by Pakistani industries after independence in 1947. [11] [12]
Natural gas production is at a relatively high level and remaining reserves are estimated to be about 885.3 billion cu m (1 January 2009 est.). Pakistan's gas fields are only expected to last for about another 20 years at the most due to heavy industrial usage. [10] [11] The Sui gas field is the biggest natural gas field in Pakistan.
In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract.The tract is divided into an upper and a lower respiratory tract.The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.
During the closed phase of discontinuous gas exchange cycles, the spiracle muscles contract, causing the spiracles to shut tight. At the initiation of the closed phase, the partial pressure of both O 2 and CO 2 is close to that of the external environment, but closure of the spiracles drastically reduces the capacity for the exchange of gases with the external environment.

Sawan Gas Field is located in Nara Taluka, Sindh, Pakistan. It is a joint venture of OMV Pakistan , ENI Pakistan , PPL , Moravské naftové doly and Government Holdings (Private) Limited. [ citation needed ] Production peaked in 2007 and by late 2023, the field's operator had recovered 97% of the recoverable reserves. [ 2 ]
