Because transparency is of prime importance, the healthy cornea does not have or need blood vessels within it.
Venule
A venule is a very small blood vessel in the microcirculation that allows blood to return from the capillary beds to drain into the larger blood vessels, the veins.
Blood

Blood is circulated around the body through blood vessels by the pumping action of the heart.
Artery
An artery (plural arteries) is a blood vessel in humans and most other animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.).
Pulmonary artery
Artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.
Artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.
The pulmonary arteries are blood vessels that carry systemic venous blood returning to the right side of the heart through to the microcirculation of the lungs.
Nerve
Enclosed, cable-like bundle of nerve fibers in the peripheral nervous system.
Enclosed, cable-like bundle of nerve fibers in the peripheral nervous system.
Nerves are bundled and often travel along with blood vessels, since the neurons of a nerve have fairly high energy requirements.
Organ (biology)

Organ is a collection of tissues joined in a structural unit to serve a common function.
For example, the gland's tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the connective tissues that provide a suitable place for it to be situated and anchored.
