IN which part of the body,blood purify?

White Blood Cells\n\nThere are between 6,000 and 8,000 white cells per cubic millimetre of blood. White cells, slightly larger than red cells, are also called leukocytes. They purify and protect the body from infections. Once an infection is detected in any part of the body, the while cells move in to fight it.

when we breath oxygen it enter in to our blood which is called oxyhaemoglobin.it helps in circulation the fresh blood through entire body through artillaries and deocygenated blood goes again for circulation in heart through veins.

The human spleen is an organ that creates lymphocytes for the destruction and recycling of old red-blood cells. The spleen is also a blood reservoir. It supplies the body with blood in emergencies such as a bad cut. The speen is also the location where white blood cells trap organisms.

The Circulation of Blood\n\nThe human circulatory system is really a two-part system whose purpose is to bring oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood out into two major loops or cycles. In the systemic loop, the blood circulates into the body’s systems, bringing oxygen to all its organs, structures and tissues and collecting carbon dioxide waste. In the pulmonary loop, the blood circulates to and from the lungs, to release the carbon dioxide and pick up new oxygen. The systemic cycle is controlled by the left side of the heart, the pulmonary cycle by the right side of the heart. Let’s look at what happens during each cycle:\n\nThe systemic loop begins when the oxygen-rich blood coming from the lungs enters the upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral valve and the blood flows down into the left ventricle. When the ventricles contract during a heartbeat, the blood on the left side is forced into the aorta. This largest artery of the body is an inch wide. The blood leaving the aorta brings oxygen to all the body’s cells through the network of ever smaller arteries and capillaries. The used blood from the body returns to the heart through the network of veins. All of the blood from the body is eventually collected into the two largest veins: the superior vena cava, which receives blood from the upper body, and the inferior vena cava, which receives blood from the lower body region. Both venae cavae empty the blood into the right atrium of the heart.\n\nFrom here the blood begins its journey through the pulmonary cycle. From the right atrium the blood descends into the right ventricle through the tricuspid valve. When the ventricle contracts, the blood is pushed into the pulmonary artery that branches into two main parts: one going to the left lung, one to the right lung. The fresh, oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.\n\nAlthough the circulatory system is made up of two cycles, both happen at the same time. The contraction of the heart muscle starts in the two atria, which push the blood into the ventricles. Then the walls of the ventricles squeeze together and force the blood out into the arteries: the aorta to the body and the pulmonary artery to the lungs. Afterwards, the heart muscle relaxes, allowing blood to flow in from the veins and fill the atria again. In healthy people the normal (resting) heart rate is about 72 beats per minute, but it can go much higher during strenuous exercise. Scientists have estimated that it takes about 30 seconds for a given portion of the blood to complete the entire cycle: from lungs to heart to body, back to the heart and out to the lungs.\n\n^_^

Veins carry deoxygenated blood from the organs and tissues back to the heart.\nDeoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part which drains the portal cyrculation too full with nutrients to nourish the body.

Respiratory and circulatory.\n\nRespiratory brings oxygen into your body.  Circulatory pumps blood, which carries the oxygen, to the cells in the rest of your body.

i don't know them all...but i'll try out some! =D\n1.tissue\n2. red blood cells [not sure though, sorry]\n3. blood plasma\n7.white blood cells\n8.platelets\n9.1%\n10.haemoglobin\n\ni recalled these from what i studied before....hope they're not too far off!! =D i tried!! =D

plasma is what makes up 55% of the blood. it carries chemicals, horomones, etc throughtout your body. does that help? i just did a unit on all of that in biology class.

The kidneys . They discard electrolytes through a membrane that the body doesn't use such as uric acid and keep those that the body uses like water. Other filters in the body are lungs, skin, liver,  and spleen

Arteries\n\nThere are two major kinds of blood vessels, veins and arteries. arteries run from the heart to all the other body parts, and the heart pumps fresh blood into the arteries. All the cells in the body draw nourishment and oxygen from this blood and leave out waste and carbon dioxide. The veins then carry this impure blood back to the heart. The blood that goes to the lungs brings back extra oxygen and the liver and the small intestine play a major role in introducing nourishment into the blood stream

always in your arm. Blood travels first to your arm from your lungs. Blood is oxygenated in your lungs. Therefore there is more pressure in blood near your lungs. The first places after lungs have hte most pressure. Then slowly it decreases. The legs get teh least pressure. When blood goes across capellaries and hte O2 is used up and the pressure is very low. It is lowest in veins since all oxygen has been used up. It is also lowest far away from the heart because the heart increases pressure.

The heart is what pumps blood and is the centerpiece of the circulatory system. Without it the blood could not carry the nutrients the body needs. The lungs take in oxygen to help feed the bloodstream. Basically both organs do the same job, just in different ways and for the same end. Keeping YOUR blood infused with the nutrients the body requires to sustain itself. Hope this helps.

A lot, actually. The kidney and the small and large intestines are the most well-known ones. But your skin actually does it's share of excreting waste from your body too. And so do your lungs. Carbon dioxide is a waste product after all.

Your heart is a pump that circulates blood through the many veins and arteries in your body...oxygenated blood leaves your heart ,in your arteries, flows to your tissues, organs and cells depositing oxygen then returns through your veins back through your lungs to heart to re oxygenate the the cycle starts over.
