There are four types of Vedas – Rigveda, Samaveda, Yajurveda, and Atharvaveda. One of the best sources of Ancient Indian History is Vedic literature. Vedas have formed the Indian scripture. The ideas and practices of Vedic religion are codified by the Vedas and they also form the basis of classical Hinduism.

Veins are a type of blood vessel that return deoxygenated blood from your organs back to your heart. These are different from your arteries, which deliver oxygenated blood from your heart to the rest of your body. The aorta is the large artery leaving the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.

A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers. A whole number is any positive number(0 through infinity) (including non-integers). An integer includes whole numbers and negative whole numbers. Integers can be positive, negative, or zero. For example: 1, -1, 0, 101 and -101. They can be ordered by being placed on a number line; the number to the right is always greater than the one to the left.
