Document Summary
Lecture #23: heart and major blood vessels: 10th may 2018. Describe the anatomical pathway of blood through the heart. Identify the major blood vessels of the head, heart, abdomen, upper and lower limbs. Double-layered wall= tough fibrous- stops infection (outer) and serous- movement of heart- hence lubrication and slippery movement (inner) Sensory innervation by phrenic nerves (c3, c4, c5) Sensory fibres on the pericardium- lets you know if the pericardium is breached from the phrenic nerve (cervical spine) Innervates the diaphragm- explains the referred pain areas from a heart attack. Heart location: (inferior, superior as well) middle mediastinum. Perfectly wedged between the vertebral column and the sternum (cardiopulmonary resuscitation) Coronary sinus drains the deoxygenated blood from the myocardium. Towards the pulmonary arteries towards the lungs then oxygenated and then veins begins towards the lungs. Artery through the heart- bicuspid- through the aortic ach. And then the neck and the body.
