The proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney.The PCT connects Bowman's capsule with the proximal straight tubule, and it is essential for the reabsorption of water and solutes from filtrate within the nephron.lomerular filtrate that has not been reabsorbed passes from the proximal convoluted tubule into the proximal straight tubule and into the loop of Henle and the distal convoluted tubule.
General Interest. Barack Obama elected as Americaâs first black president. On this day in 2008, Senator Barack Obama of Illinois defeats Senator John McCain of Arizona to become the 44th U.S. president, and the first African American elected to the White House.
President Obama made history in 2008 as the first African American president in U.S. history. President Obama gives a keynote address during the Civil Rights Summit at the LBJ Presidential Library on the University of Texas campus in Austin, Texas, USA, 10 April 2014. While whites and Hispanics are far more likely to describe Obama as mixed race, a strong majority of African Americans see him as black. And black voters voted in historically large numbers for Obama. He won 93 percent of the African American vote in 2012 and 95 percent among that group in 2008. Obama, for his part, struggled for much of his life in how to define himself racially with a Kansas-born white mother and a Kenyan father.
