The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. ... Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells which stabilize the tissue.

Parts of the Heart. The heart acts as a pump. The right portion receives blood (which is impure) from the body and pumps the same to the lungs for purification (oxygenation). The impure blood enters the heart from two large veins called the superior and inferior vena cava
