The Conduction System of the Heart
Pacemaker cells at the sinoatrial node (SA) fire spontaneously and act as a pacemaker. They form the conduction system for the heart. The SA node sets the pace since it […]
Systemic Circulation
The left side of the heart pumps blood throughout the body. The left ventricle pumps oxygenated blood into the aorta. The aorta branches into many arteries that travel to organs. The arteries branch into many arterioles in tissue. The arterioles branch into thin-walled capillaries for exchange of gases and nutrients. Deoxygenated blood begins its […]

One day after I drove the jeep I pulled the emergency brake to park. I guess the sunglasses were under the brake and I crushed […]

Around 10:00 about twenty moms and one dad got […]
