In order to turn percent to a fraction, first, we write it as 48/100. Then, from there we simplify it to the simplest form.
48/100 = (48/4) / (100/4) = 12/25
So, 48% <span>expressed as a fraction in simplest form is 12/25.</span>
The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.
Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.
Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.
This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.

The hypothalamus is the main control center for the autonomic nervous system.
Hypothalamus is part of the brain that contains a number of small nuclei. It link the nervous system to endocrine system via pituitary gland, In addition hypothalamus control many bodily function example release of hormone from pituitary gland.
