Any of the muscular elastic tubes that form a branching system and that carry blood away from the heart to the cells, tissues, and organs of the body.
The only veins that have oxygen in them are the pulmonary veins. The definition of a vein is a blood vessel that carries blood to the heart. This blood is usually de-oxygenated, but the pulmonary veins are the exception.
a swollen vein or group of veins in the region of the anus.
The definition of the word 'bulged' is to swell or protrude to an unnatural extent. For example, one could say, 'The veins in his neck bulged out, when he was angry.".

The veins are small tube like structures inside the body that help with the flow of blood. The veins actually move blood all over the body, they work in tandem with the arteries, which takes blood to and from the heart.
Parallel venation is the term used to describe the arrangement of leaf veins in monocotyledonous plants. The veins are arranged parallel to each other, thus parallel venation (as opposed to the branched or net venation of dicotyledonous plants)
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
Reticulate venation is a type of leaf venation pattern in which the veins form a network branching structure throughout the leaf. This pattern is common in dicotyledonous plants and allows for efficient nutrient transport and support for the leaf.
Any of the muscular elastic tubes that form a branching system and that carry blood away from the heart to the cells, tissues, and organs of the body.
There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.
There are three types of veins, superficial veins that are just beneath the surface of the skin, deep veins that are large blood vessels found deep inside muscles, and perforator veins that connect the superficial veins to the deep veins.
Pulmonary veins
