Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Answer:
Myelination
Explanation:
The white matter is the tissue present in the brain which is composed of the neurons enclosed in the myelin sheath. The presence of the myelin sheath gives white colour to the matter.
The cognitive process like the new experiences and learning ability is the result of the myelination process which forms a myelin sheath around the axon of the neuron.
The formation of the myelin sheath provides insulation and increase the speed of transmission in the neurons allows us to think and learn new things.
Thus, Myelination is the correct answer.
The correct option is this: IT INCREASES THE AMOUNT OF ENERGY YOUR BODY USES AT REST.
Regular exercise increases the amount of energy that one burns while exercising, but it does not stop there, it also increases the amount of energy that one burns while the body is at rest. This is because regular exercise speed up the rate of metabolism of the body and this rate remain high even when the body is at rest, thus, an individual who exercises regularly will lose more energy at rest than some one who is not actively exercising.<span />
