We have heard about Respiration. In human beings, respiration is a cellular activity which takes place in the presence of oxygen and in result produces carbon dioxide. Jamal model is a clear manifestation of that process. Medulla is the region of a brain that controls the respiration activity. When we breathe we take in oxygen and the excess amount of carbon dioxide is removed from out body.
Brains cells have capability to detect the carbon concentration in blood and add excess amount of carbon from body to the air.

Answer:
Manuel Roxas, (born Jan. 1, 1892, Capiz, Phil.—died April 15, 1948, Clark Field, Pampanga), political leader and first president (1946–48) of the independent Republic of the Philippines.
After studying law at the University of the Philippines, near Manila, Roxas began his political career in 1917 as a member of the municipal council of Capiz (renamed Roxas in 1949). He was governor of the province of Capiz in 1919–21 and was then elected to the Philippine House of Representatives, subsequently serving as Speaker of the House and a member of the Council of State. In 1923 he and Manuel Quezon, the president of the Senate, resigned in protest from the Council of State when the U.S. governor-general (Leonard Wood) began vetoing bills passed by the Philippine legislature. In 1932 Roxas and Sergio Osmeña, the Nacionalista Party leader, led the Philippine Independence Mission to Washington, D.C., where they influenced the passage of the Hare-Hawes-Cutting Act. Roxas was later opposed by Quezon, who held that the act compromised future Philippine independence; the Nacionalista Party was split between them on this issue.
