A normal recording of ECG shows P, QRS, and T waves. Sometimes a U wave is also recorded.In the recording strip of paper, there are horizontal and vertical.
Electrocardiogram (ECG) deals with the study of electrical activity of the heart. The instrument used to record the activity is called electrocardiograph..
The cardiac center, is situated in the medullary reticular formation in the dorsal motor nucleus and nucleus ambiguus, which give rise to vagus. The vagus.
The mechanical activity of the heart produces heart sounds. Sounds are produced due to vibrations caused by the closure of valves, contraction of the myocardium.
Capillaries are the exchange vessels, present between arterioles and venules. The arterioles in some places end in metarterioles, which in turn end in.
Blood flow through the skin is variable depending upon the body temperature regulation (flow ranges from 1 ml to 150 ml/100 gm/min.). The cutaneous blood.
Blood flow to the brain is supplied by cerebral arteries, which form the circle of Willis at the base of the brain. The venous drainage from the brain.
The blood flow in the left coronary artery is phasic in nature. The left ventricular pressure developed during systole is greater and hence the coronary.
