The network of specialised cells that conduct through the body of a plant both water (in xylem tissue) and assimilated products (in phloem tissue).
The tubular blood-conducting network of the body composed of arteries, veins, and capillaries.
The series of vessels such as veins, arteries and capillaries, carrying blood around the body.
The blood vessels: the arteries, capillaries, and veins. The vessels carry blood to and from the heart and contribute to the regulation of blood pressure. Exchange of materials between the blood and tissues takes place in capillary networks. Pulmonary and systemic circulation are included. Moreover, the lymphatic system, which returns a significant amount of tissue fluid to the venous circulation, is usually considered a part of the vascular system.
