THE CARDIAC CYCLE Where there is electrical natural process coordinates the rhythmic contraction and relaxation. The cardiac cycle consists of two phases, called the diastole and systole. The diastole is where the life ventricles are relaxed and the systole is ejected from the ventricles. During the diastole is the sinus node generates an impulse that forces the two atria to contract. In this process the tricuspid and mitral value are undetermined and blood goes from the atria in to the relaxed ventricles. The end of diastole the electric impulse reaches the ventricles cause them to contract. In the systole the contracting ventricles closed the tricuspid and the mitral valves. And afterward the contract of the blood inside the ventricles rises to force the pulmonary and aortal value to open and blood is ejected into the pulmonary artery and the aorta. As the ventricle relaxed is lower in the atria, the tricuspid and mitral set open again and then the cardiac starts. The lub dub is the crush knockers that respond to the two sets of contract during the cardiac cycle.
look RATE- For an adult resting heart should be in the range from 60 c crush per minutes, and for an athlete a normal resting heart rate will be closer to 40 beats per minute.
The way to measure you heat rate would be laurel facing upward, place two finger on the ruffle side of wrist or place your index and ternary fingers on your neck to the side of your windpipe. If your resting heart is over 100 beats a minutes you need to call your doctor, and if you hasten sign of fainting or shortness of breath.
PULSE Blood pressure reading are given in two numbers. The roundabout number is the maximum pressure your heart exerts while trouncing (systolic pressure), and the bottom number is the amount of pressure in your arteries among beats (diastolic pressure). If youre resting blood pressure is 120/80 millimeters of mercury (mmHG), your pulse pressure is 40- which is considered a...If you want to get a full essay, order it on our website: Orderessay
