Overview of the Vascular System Blood moves through the circulatory system as a result of being pumped out by the heart. Blood leaving the heart through the arteries is saturated with oxygen. The arteries break down into smaller and smaller branches in order to bring oxygen and other nutrients to the cells of the body's tissues and organs.

- Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, so it can receive more oxygen to be sent back to the body via the arteries. As the heart beats, you can feel blood traveling through the body at your pulse points — like the neck and the wrist — where large, blood-filled arteries run close to the surface of the skin. The blood that flows through this network of veins and arteries is called whole blood. Whole blood contains three types of blood cells: red blood cells

How does blood travel throughout the human body? The left ventricle pumps oxygen-rich blood out of the heart and into an artery called the aorta. From the aorta, blood branches out into a series of ever smaller tube-like vessels: arteries, arterioles and finally capillaries. The capillaries deliver the blood's oxygen and nutrients to cells.

- Explain the structure of arteries, veins, and capillaries and how blood flows through the body. 1  Arteries carry blood away from the heart; the main artery is the aorta.  Smaller arteries called arterioles diverge into capillary beds, which contain 10-100 capillaries that branch among the cells and tissues of the body.

About the Heart and Blood Vessels A network of arteries and veins also carry blood throughout the body: Arteries transport blood from the heart to the body tissues. Veins carry blood back to the heart.ow the heart works. The heart is a large, muscular organ that pumps blood filled with oxygen and nutrients through the blood vessels to the body tissues. It's made up of: Four chambers. The two upper chambers, the atria, receive and collect blood.

While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries. The effective arterial blood volume is that extracellular fluid which fills the arterial system.

The arteries are the large blood vessels that carry blood from the heart to all the organs and muscles of the body, to give them the energy and oxygen they need.The arteries manage the flow of blood by controlling the speed and direction it flows in.hat happens when your arteries become too narrow. The higher your blood pressure is, the greater the chance that the extra pressure could make a weak artery burst. Also, the narrower your arteries are, the greater the risk that they could become blocked.

How does blood flow through your lungs? Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale.

Blood Flow and Blood Pressure Regulation With each rhythmic pump of the heart, blood is pushed under high pressure and velocity away from the heart, initially along the main artery, the aorta . In the aorta, the blood travels at 30 cm/sec. From the aorta, blood flows into the arteries and arterioles and, ultimately, to the capillary beds. As it reaches the capillary beds, the rate of flow is dramatically (one-thousand times) slower than the rate of flow in the aorta.

Artery After travelling from the aorta, blood travels through peripheral arteries into smaller arteries called arterioles, and eventually to capillaries. Arterioles help in regulating blood pressure by the variable contraction of the smooth muscle of their walls, and deliver blood to the capillaries.

Physiology of Circulation Blood Flow. Blood flow refers to the movement of blood through the vessels from arteries to the capillaries and then into the veins. Pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels.Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels. As the total cross-sectional area of the vessels increases, the velocity of flow decreases.lood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels.

How the Heart and Blood Vessels Work Arteries are blood vessels that carry blood away from the heart. Because they are under high pressure, arteries have strong elastic walls. The largest artery from the heart is called the aorta. This artery branches into smaller and smaller vessels before finally reaching the tiny capillaries where oxygen and nutrients are delivered to organs and tissues. The other main artery from the heart goes to the lungs where its blood picks up oxygen. Veins are the blood vessels that carry blood back ...

Cardiovascular System Anatomy Blood vessels are the body’s highways that allow blood to flow quickly and efficiently from the heart to every region of the body and back again. The size of blood vessels corresponds with the amount of blood that passes through the vessel. All blood vessels contain a hollow area called the lumen through which blood is able to flow.

Blood Flow Through The Heart This blood carries little oxygen, as it is returning from the body where oxygen is used. The blood first enters the right atrium. It then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes the blood through the pulmonic valve into the pulmonic artery. This artery is unique: It is the only artery in the human body that carries oxygen-poor blood.
