The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste. <sep>What does the digestive system do?<sep>Digests food

After the August missile strikes, diplomatic options to press the Taliban seemed no more promising than military options. The United States had issued a formal warning to the Taliban, and also to Sudan, that they would be held directly responsible for any attacks on Americans, wherever they occurred, carried out by the  Bin Laden network as long as they continued to provide sanctuary to it. For a brief moment, it had seemed as if the August strikes might have shocked the Taliban into thinking of giving up  Bin Laden. On August 22, the reclusive Mullah Omar told a working-level State Department official that the strikes were counterproductive but added that he would be open to a dialogue with the United States on  Bin Laden's presence in Afghanistan. Meeting in Islamabad with William Milam, the U.S. ambassador to Pakistan, Taliban delegates said it was against their culture to expel someone seeking sanctuary but asked what would happen to  Bin Laden should he be sent to Saudi Arabia. Yet in September 1998, when the Saudi emissary, Prince Turki, asked Mullah Omar whether he would keep his earlier promise to expel  Bin Laden, the Taliban leader said no. Both sides shouted at each other, with Mullah Omar denouncing the Saudi government. Riyadh then suspended its diplomatic relations with the Taliban regime. (Saudi Arabia, Pakistan, and the United Arab Emirates were the only countries that recognized the Taliban as the legitimate government of Afghanistan.) Crown Prince Abdullah told President Clinton and Vice President Gore about this when he visited Washington in late September. His account confirmed reports that the U.S. government had received independently. Other efforts with the Saudi government centered on improving intelligence sharing and permitting U.S. agents to interrogate prisoners in Saudi custody. The history of such cooperation in 1997 and 1998 had been strained. Several officials told us, in particular, that the United States could not get direct access to an important al Qaeda financial official, Madani al Tayyib, who had been detained by the Saudi government in 1997.67Though U.S. officials repeatedly raised the issue, the Saudis provided limited information. In his September 1998 meeting with Crown Prince Abdullah, Vice President Gore, while thanking the Saudi government for their responsiveness, renewed the request for direct U.S. access to Tayyib. The United States never obtained this access. An NSC staff-led working group on terrorist finances asked the CIA in November 1998 to push again for access to Tayyib and to see "if it is possible to elaborate further on the ties between Usama bin Ladin and prominent individuals in Saudi Arabia, including especially the  Bin Laden family." One result was two NSC-led interagency trips to Persian Gulf states in 1999 and 2000. During these trips the NSC, Treasury, and intelligence representatives spoke with Saudi officials, and later interviewed members of the  Bin Laden family, about Usama's inheritance. <sep>Who was the US trying to contact during strained Saudi Relations in 1997, when they were denied the opportunity to question detainees?<sep>Bin laden

Crew members ran for their lives when overhanging metalwork crashed onto a stage in a Toronto park Saturday afternoon, pinning and killing one man, authorities said. The collapse happened around 4 p.m., one hour before spectators were set to begin streaming in for a concert by the alternative rock group Radiohead. Several people were on the stage at the time, preparing for the show, when scaffolding-like material towering about 50 feet above collapsed. "Unfortunately, four people were hurt," Toronto police Constable Tony Vella said. "The remainder of the people, when they heard the stage coming (down), ran from the area." Firefighters arrived to find one man "trapped under the structure," said Toronto fire Platoon Chief Tony Bellavance. They helped to extricate the man, then moved away from what was then still considered an "unstable structure," Bellavance added. Paramedics, who happened to be at the scene in preparation for the concert, "immediately rendered aid," according to on-site Toronto Emergency Medical Services commander Peter Rotolo. The victim -- who has not been identified, amid efforts to contact his next of kin -- was pronounced dead at the scene. Police said he was in his 30s. Another man who suffered serious injuries due to the collapse was transported to Toronto's Sunnybrook Hospital, Ian McClelland of the city's EMS department said. The 45-year-old man suffered a head injury that isn't considered life-threatening, according to Toronto police. Two other men with minor injuries were assessed and released, McClelland said. Aerial footage afterward showed that some metal framing -- some of it covered in a blue material -- crumpled on the stage, which was in front of a large grassy area. Some of the scaffolding-like material remained standing, reaching about 50 feet in the sky. The stage was being set up especially for the Radiohead concert, Vella said. At the time it came down, the weather was good with no storm rolling through or significant winds, added fellow police Constable Harrison Ford. <sep>Who "immediately rendered aid" when overhanging metalwork crashed onto a stage in a Toronto park Saturday afternoon?<sep>Emergency medical services
