The kidneys remove wastes and extra water from the blood to form urine. Urine flows from the kidneys to the bladder through the ureters. The wastes in your blood come from the normal breakdown of active muscle and from the food you eat. Your body uses the food for energy and self-repair. After your body has taken what it needs from the food, waste is sent to the blood.
The land to the north of the Gila River, in United States territory, was too mountainous. President Pierce instructed the American minister to Mexico, James Gadsden, to purchase as much territory in northern Mexico as possible.he Gadsden Purchase represented the last parcel of land acquired by the United States to complete the 48 mainland states. The transaction with Mexico was controversial and it intensified the simmering conflict over slavery and helped to inflame the regional differences that eventually led to the Civil War.
Mexican Cession lands were captured in the MexicanâAmerican War in 1846â48, and ceded by Mexico in the Treaty of Guadalupe Hidalgo, where Mexico agreed to the present MexicoâUnited States border except for the later Gadsden Purchase.
