Document Summary
Pathologies of having heart in pericardial sac: cardiac tamponade. Heart has an inherent rhythm determined by the sa node. Sympathetic system involves innervation from the cervical and thoracic chain ganglion; w input from the cardioacceleratory centre of the brain, signals down through these neurons and go to both the. Sa node and av node, regulating the pacing slows down the heart with ach. Sns releases ne, making the blood beat faster. Antagonist is the pns, mediated through the vagus nerve (travels to sa and av node too), and. This is a controlled system, but if we have a heart transplant, this process won"t happen. Having talked about the heart, we are going to talk about the systemic circ oxy"d blood comes out of the heart from the lv, through the aorta, and branches out to the whole body. First branches of the aorta are the right and left coronary arteries; when we follow the aorta, we.
