The attackers inserted IFrame code into the saved search results of legitimate websites. When a visitor clicked on a link from the compromised search tool, he would be redirected to a malicious website by the IFrame code. The unsuspecting user's computer would then be vulnerable to the automatic download of malware.
A Human's Heart. Like the human heart, the chicken heart has four chambers - a right atrium and ventricle which receives deoxygenated blood from the body and sends it to the lungs and a left atrium and ventricle which receives oxygenated blood from the lungs and sends it to the body. Birds have a much higher metabolic rate than humans. The average body temperature of a chicken is 41-45 degrees C, compared to a human's average body temperature of 37 degrees C. The pulse rate of a chicken can reach as high as 400 beats/min.
Chambers and valves of the heart. A normal heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.
