how would a dislodged piece of plaque in the cardiovascular system most likely affect an otherwise healthy person?

the right pulmonary artery could become blocked, restricting blood flow to the right lung.
a narrow region of the superior vena cava could become blocked, restricting blood flow to the heart.
a smaller artery in a leg could become blocked, restricting blood flow to capillaries in the leg.
a narrow vein in the brain could become blocked, restricting blood flow to capillaries in the brain.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
