Breccia is a rock formed from angular gravel and boulder-sized clasts cemented together in a matrix. The angular nature of the clasts indicates that they have not been transported very far from their source. There are several modes of formation for breccia.
Low blood pressure results in inadequate blood flow -- and therefore inadequate delivery of oxygen and nutrients -- to the heart, brain, kidneys, and other organs. This can be damaging and cause permanent harm. The heart circulates blood throughout the body with every beat.
