week 8 cycle 3 Make an anatomical model of the human heart! All it takes is some aluminum foil, crepe paper, pipe cleaners, and clay! Also, instructions for how to build a heart pump and represent blood flow!
Chambers and Associated Great Vessels The right and left atria are the receiving chambers of the heart. The right ventricle pumps blood into the pulmonary trunk; the left ventricle pumps blood into the aorta.
Scientists have been able to reverse heart failure in pigs by delivering a new gene to the heart that makes it better at pumping blood and supplying the body with oxygen. The goal is to reverse heart failure with a single injection. This time around, Dr. Hajjar said, he and his team have reengineered the viral vector to make it more effective at delivering the new gene to the heart. The gene therapy was safe and reduced heart failure by 25 percent in the left ventricle by 20 percent in the…
