  Vascular plant - Wikipedia, the free encyclopedia
The vascular plants are plants in the Kingdom Plantae (also called Viridiplantae) that have specialized tissues for conducting water.
Vascular plants have vascular tissues, enabling the plants to evolve to a larger size.
In vascular plants, the principal generation phase is the sporophyte, which is diploid with two sets of chromosomes per cell.

 CIRCULATORY SYSTEMS
The vertebrate cardiovascular system includes a heart, which is a muscular pump that contracts to propel blood out to the body through arteries, and a series of blood vessels.
Systemic pressure is sensed by receptors in the arteries and atria.
Two main routes for circulation are the pulmonary (to and from the lungs) and the systemic (to and from the body).

 Pharyngula: Evolution of vascular systems
It's interesting that acoelomate flatworms lack a discrete circulatory system, but they do have excretory epithelia—it implies that maybe the heart and blood vessels were cobbled together out of genetic pathways that were first pioneered in the building of the organism's sewage treatment system.
Vascular progenitors (cardioblasts) migrate dorsally, meet in the midline and form the myoepithelial dorsal vessel (top).
Progenitors of the vascular system and blood derive from the lateral plate.

 Seedless Vascular Plants   (Site not responding. Last check: )
The evolution of vascular plants is tied to Bryophyta (mosses, liverworts and hornworts for you un-science types) but it is still not known whether seedless vasculars evolved independently or from shared structures within Bryophyta.
The structure of the vascular plant can be broken down into three parts: subterranean root systems, where water and minerals are absorbed; aerial root systems, where photosynthesis occurs; and vascular tissue, where tubular cell chains deliver materials between different organs of the plant.
Vascular plants also have cuticles, which are waxy coverings on the surface of stems and leaves that prevent dehydration in terrestrial plants.

 Water vascular system - Wikipedia, the free encyclopedia
The water vascular system is a hydraulic system used by echinoderms, such as sea stars and sea urchins, for locomotion, food and waste transportation, and respiration.
The system is composed of canals connecting numerous tube feet.
Echinoderms move by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract.

 Vascular Disease Screening
But they know very little about vascular disease outside the heart, says William R. Flinn, M.D., head of vascular surgery and the Maryland Vascular Center at the University of Maryland Medical Center and professor of surgery at the University of Maryland School of Medicine.
That's despite the fact that many vascular diseases can produce stroke, which is the third leading cause of death in the United States.
Dr. Flinn says it's important to understand that vascular disease outside the heart does occur in a variety of different locations -- the carotid arteries in the neck, the aorta, the arteries in the legs and arms and even disease in the veins.
