How does blood travel from your heart to your body and back again?

Question

HEY!

Answer 1

blood runs from the heart to all the parts of the body through arteries and it runs back to heart from all the body parts through veins. this is exactly opposite when the blood runs from the heart to the lungs to pick up oxygen.

Answer 2

the heart is just like a pump with 4 chambers.it continuously pump blood in a fixed pressure called the blood pressure or pulse. the two blood vessels are arteries and veins. the arteries carry the pure oxygenated blood from the heart to the organs and the body parts. on the other hand the veins carry the impure or DE-oxygenated blood from the body parts to the heart. in this manner the blood travels from your heart to your body and back again.

hope the answer solves your problem.

Answer 3

Your heart is a pump. Every time it beats blood is being sucked into it, and then pushed out at a certain pressure (your blood pressure). This then flows around your body in your blood vessles (veins and atteries) with the aid of valves.

Answer 4

Left ventricle -> arteries -> capillaries -> veins - > right auricle -> right ventricle -> Pulmonary artery -> lungs -> pulmonary vein -> left auricle -> Left ventricle and then the cycle repeats.
Heart has four chambers two auricles above and two ventricles below. There is valve between auricle and ventricle such that it allows blood to flow from auricle to ventricle and not back.So, when ventricle pumps the blood out, it does not flow back to auricle. There is no passage between left and right.
Arteries carry blood away from heart and veins bring them towards heart. Except pulmonary artery (which takes impure blood to lungs all other arteries carry oxygenated blood (pure blood in layman terms)
All veins except pulmonary vein carry deoxygenated blood (or impure blood) Pulmonary vein carries oxygenated blood from lungs to heart.

Answer 5

With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells. Each day, 2,000 gallons (more than 7,570 liters) of blood travel many times through about 60,000 miles (96,560 kilometers) of blood vessels that branch and cross, linking the cells of our organs and body parts. From the hard-working heart to our thickest arteries to capillaries so thin that they can only be seen through a microscope, the heart and circulatory system (also called the cardiovascular system) is our body's lifeline, delivering blood to the body's tissues.

What Is the Heart and Circulatory System?
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when necessary. It beats about 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime.

The heart gets messages from the body that tell it when to pump more or less blood depending on an individual's needs. When we're sleeping, it pumps just enough to provide for the lower amounts of oxygen needed by our bodies at rest. When we're exercising or frightened, the heart pumps faster to increase the delivery of oxygen.

The heart has four chambers that are enclosed by thick, muscular walls. It lies between the lungs and just to the left of the middle of the chest cavity. The bottom part of the heart is divided into two chambers called the right and left ventricles, which pump blood out of the heart. A wall called the interventricular septum divides the ventricles.

The upper part of the heart is made up of the other two chambers of the heart, called the right and left atria. The right and left atria receive the blood entering the heart. A wall called the interatrial septum divides the right and left atria, which are separated from the ventricles by the atrioventricular valves. The tricuspid valve separates the right atrium from the right ventricle, and the mitral valve separates the left atrium and the left ventricle.

Two other cardiac valves separate the ventricles and the large blood vessels that carry blood leaving the heart. These valves are called the pulmonic valve, which separates the right ventricle from the pulmonary artery leading to the lungs, and the aortic valve, which separates the left ventricle from the aorta, the body's largest blood vessel.

Blood vessels carrying blood away from the heart are called arteries. They are the thickest blood vessels, with muscular walls that contract to keep the blood moving away from the heart and through the body. In the systemic circulation, oxygen-rich blood is pumped from the heart into the aorta. This huge artery curves up and back from the left ventricle, then heads down in front of the spinal column into the abdomen. Two coronary arteries branch off at the beginning of the aorta and divide into a network of smaller arteries that provide oxygen and nourishment to the muscles of the heart.

Unlike the aorta, the body's other main artery, the pulmonary artery, carries oxygen-poor blood. From the right ventricle, the pulmonary artery divides into right and left branches, on the way to the lungs where blood picks up oxygen.

Arterial walls have three layers:

The endothelium is on the inside and provides a smooth lining for blood to flow over as it moves through the artery.
The media is the middle part of the artery, made up of a layer of muscle and elastic tissue.
The adventitia is the tough covering that protects the outside of the artery.
As they get farther from the heart, the arteries branch out into arterioles, which are smaller and less elastic.

Blood vessels that carry blood back to the heart are called veins. They're not as muscular as arteries, but they contain valves that prevent blood from flowing backward. Veins have the same three layers that arteries do, but are thinner and less flexible. The two largest veins are the superior and inferior vena cavae. The terms superior and inferior don't mean that one vein is better than the other, but that they're located above and below the heart.

A network of tiny capillaries connects the arteries and veins. Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Answer 6

deoxygenated blood from the head passes through the superior vena cava while deoxygenated blood from the chest down enters the inferior vena cava. they enter the right atrium passing through the tricuspid valve to make sure that blood flow doesn't go back to the atrium and goes straight to the right ventricle. it passes then to the pulmonary valve into the pulmonary artery to the lungs to get oxygen. after they get oxygen they then enter the pulmonary veins into the left atrium passing to the mitral valve into the left ventricle. then into the aortic valve through the aorta then through all the arteries in the body to distribute oxygen. After it has distributed oxygen the blood goes back again the vena cava then the cycle continues....

P.S.
the purpose for the valves are to make sure blood flow continues and doesn't flow back to one section in the heart.
* all the veins are colored blue since they don't carry oxygen except for the pulmonary vein since they carry oxygen back to the heart for the distribution. all the arteries are colored red for the opposite reason and still with the exception of pulmonary artery.
*all arteries carry oxygen to the rest of the body (except pulmonary artery) while veins carry blood without oxygen into the heart (except for the pulmonary vein)

Answer 7

by the blood vessels. thi vessel flow blood which is pumped by our heart,bringin with them some oxygen to burn the food, to make an energy. When the food is burnt the carbon dioxide is released. the blood journey end to the heart; the point it started.

Answer 8

Through your arteries to your tissues, and back to your heart and lungs through your veins. Your heart is the pump that provides the pressure to keep it circulating.

Answer 9

Cardiovascular System

Answer 10

Your heatr pumps the blood all over your body.
