three arteries that emerges from surface of aortic arch supplies blood to
shoulders, head and arms
10/12 circulation – process of pressure driven bulk flow of blood to all parts of the body  pressure relies on cardiovascular components  heart o four chambered pump  blood vessels o tubes heart pumps fluid in to o arteries, arterioles, capillaries, venules, and veins structure of the heart  right atrium o receives deoxygenated blood from body  right ventricle o pumps deoxygenated blood to lungs  left atrium o receives oxygenated blood from the lungs  left ventricle o pumps oxygenated blood from the body  fibrous skeleton o separates atria from ventricles  so atria work as one unit and ventricles work as separate unit o forms t (i) ventricles are in diastolic phase. the arrows indicate blood entering the ventricles. during a ventricular diastole, the valves between atria and ventricles open which allow the entry of blood into the ventricles.(ii) 1 – pulmonary artery, 2 – pulmonary veins(iii) closing of the bicuspid and tricuspid valves causes the ‘lubb’ sound, and the closing of semilunar valves causes the ‘dup’ sound.(iv) coronary artery supplies oxygenated blood to the heart muscles. (v) cross-section of an artery and a vein: Sensory input from barorecepors in the carotid and aortic sinuses.  
Sensory input from the chemoreceptors in the carotid and aortic bodies.  
Cranial nerves IX and V relaying impulses to the cardiovascular center.  
The balance of sympathetic and parasympathetic impulses from the cardiovascular center. an abnormal sound heard due to blood flow turbulence in your carotid artery. this sound can be attributed to a carotid artery aneurysm, dissection or partial blockage, or the same diagnoses in the aortic artery further upstream. please see a vascular surgeon or cardiologist for proper diagnosis and treatment. thanks for trusting in healthtap. see more... blood flow to intestinal area increase and hr will increase to compensate and keep blood flow to other organs. not a good habit to develop. see more... that's a bit of an ovary-action. **Pure substance – ethyl alcohol, oxygen, carbon, distilled water mixture – blood, steel** it's likely either a thromboses hemorrhoid with the surface slightly ulcerated, if so it will resolve on it's own or it's a small perianal abscess which if draining will also likely resolve. if your symptoms persist for more than a few weeks or recur see your doc. see more... brief answer: its probably the heart detailed answer: hello and welcome in hcm i can understand your concern according to the history you explain its not osteoporosis causing this pain. there are three organs that you have to control . first the heart with the following tests: repeat ecg, and the... ch3cn > ch3ch2ch3 > ar
