A standard normal distribution table shows a cumulative probability associated with a particular z-score. Table rows show the whole number and tenths place of the z-score. Table columns show the hundredths place. The cumulative probability (often from minus infinity to the z-score) appears in the cell of the table. standard normal distribution table shows a cumulative probability associated with a particular z-score.

1 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.
Blood Vessels: Pathways of blood flow in human body, hollow tubes, of which there are three types-. Arteries: Carry blood away from heart to other body parts, very muscular and elastic. Capillaries: Microscopic blood vessels where exchange of nutrients with tissues take place.LOOD VESSELS: Human beings have a closed type of circulatory system which means blood does not come into direct contact with body tissues. Instead, the blood flows in restricted pathways called blood vessels. Materials are exchanged between blood and body tissues through the walls of blood vessels.
