- An artery (plural arteries) (from Greek ἀρτηρία (artēria), meaning 'windpipe, artery')[1] is a blood vessel that carries blood away from the heart. While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries.

What Are the Names of the Teeth on a Dental Chart? It is followed by the lateral incisor, the canine or eye tooth, the first bicuspid, the second bicuspid and the first molar. This is followed by the second molar and the wisdom tooth. Starting right beneath this wisdom tooth in the lower left quadrant of the jaw is the wisdom tooth, or third molar.

Vascular Disease Understanding Vascular Disease. The vascular system is a network of blood vessels including arteries, veins, and capillaries. Arteries carry oxygen and nutrients to the body; veins return blood from the tissues to the heart. Vascular disease refers to changes that can occur in blood vessels affecting the normal flow of blood.

Vascular Tissues The vascular tissue system is composed of two different types of tissues: xylem and phloem. Although both xylem and phloem form a continuous tissue system throughout the plant body, the two tissues have different functions.ylem: The Water-Conducting Vascular Tissue. Xylem is a complex tissue composed of several different cell types. This tissue includes parenchyma cells, fibers, and two cell types specializing in water and mineral transport: tracheids and vessel members.

Vascular tissue The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.

Vascular Plants: Examples, Types & Characteristics Some types of plants, known as vascular plants, have a system of vessels within them that carry water and food throughout the plant. These vessels are found in the roots, stems, and leaves of the plant.The vascular vessels are divided into two types based on what they transport.his type of vascular plant is often referred to as a seedless vascular plant. The majority of vascular plants reproduce by creating seeds rather than spores and are classified as either gymnosperms or angiosperms. Gymnosperms are vascular plants that create cones to house their seeds.

Overview of the Vascular System What is the vascular system? The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.

Vascular disease Vascular disease is a pathological state of large and medium muscular arteries and is triggered by endothelial cell dysfunction. Because of factors like pathogens, oxidized LDL particles and other inflammatory stimuli endothelial cells become active.

- In botany, vascular tissues include xylem and phloem. Xylem is the type of vascular tissue that moves water and dissolved nutrients from the roots to the leaves. The xylem are … one-way roads, however. No particles can move down the tree through the xylem.xygen diffuses directly from the air to corneal cells to keep the cornea transparent. There are fewer blood vessels in connective tissue and bone than in high metabolic areas such as muscle cells and organ cells, but blood vessels (vascular tissue) is found all over the body.

- Artery (Definition). Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent-blood from the body back to the heart.

Vein As in arteries, there are tiny vessels called vasa vasorum that supply blood to the walls of the veins and other minute vessels that carry blood away. Veins are more numerous than arteries and have thinner walls owing to lower blood pressure. They tend to parallel the course of arteries. See also artery; capillary.

Nonvascular Plants: Examples, Definition & Characteristics Within vascular plants is the phloem, the vessel that transports food, and the xylem, which transports water. Nonvascular plants are small, simple plants without a vascular system. They do not have a phloem or xylem.

vein vein. 1. Any of the blood vessels that carry blood toward the heart. Veins are thin-walled and contain valves that prevent the backflow of blood. All veins except the pulmonary vein (which returns to the heart from the lungs) carry blood having low levels of oxygen.ein. n. 1. (Anatomy) any of the tubular vessels that convey oxygen-depleted blood to the heart. Compare pulmonary vein, artery. 2. (Zoology) any of the hollow branching tubes that form the supporting framework of an insect's wing.

What are Vascular Plants? Vascular plants have conducting, also referred to as vascular or liquefied, tissues that transport water, minerals, and photosynthetic materials throughout the plant’s roots, stems, and leaves. They differ from nonvascular plants, which do not have conducting tissues, and require water for fertilization.

- physiology: the movement of water through the vascular system. You will work in teams of four to design and perform and experiment that will help you understand the general workings of one of the two types of vascular tissue in plants, the xylem.

stem 1 The main, often long or slender part of a plant that usually grows upward above the ground and supports other parts, such as branches and leaves. Plants have evolved a number of tissue arrangements in the stem. Seedless vascular plants (such as mosses and ferns) have primary vascular tissue in an inner core, a cylindrical ring, or individual strands scattered amid the ground tissue.
