All blood coming from the heart travels through arteries but not all have high levels of oxygen.
The blood that goes to the body is high in oxygen but the blood that goes to the lungs is low in oxygen.
There it drops of carbon dioxide and picks up oxygen and carries this back to the heart to be pumped out to the body.
Blood coming from the right side of the heart to the lungs has low oxygen. Blood coming from the left side of the heart to body circulation has high oxygen.
Your heart gives oxygen to blood cells, then those carry oxygen throughout your body, and when they reach your heart again, it refills them with oxygen.
The blood turns red once it has come into contact with oxygen. This is why your veins appear blue, purple, etc, but when you cut yourself the blood is red. Not sure about details, but oxygen changed the color.
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.
Not very much. It tells the brain nothing about the blood, such as oxygen state, or how fast it is beating. However, pain can be transmitted to the brain from the heart when the heart doesn't, for example, have enough oxygen. This information is quite non-specific, though, explaining why pain from the heart in a heart attack can appear to come from the arm or jaw.
Whether they have oxygen or not, all arteries carry blood away from the heart. And, since the pulmonary arteries carry blood from the right ventricle of the heart to the lungs, it is appropriately called an artery. Any blood vessel that carries blood toward the heart is called a vein. So that is why the oxygenated blood from the lungs uses the pulmonary veins to carry it to the left atrium of the heart.
Your heart gives oxygen to blood cells, then those carry oxygen throughout your body, and when they reach your heart again, it refills them with oxygen.
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
Carries oxygenated blood from the lungs to the left atria of the heart. Brings blood from the lungs to the heart.

Because blood in your arteries are fresh from your lungs. The haemoglobin in your red blood cells have just "picked up" oxygen, they then travel to cells in your body where that oxygen is used for the cells to respire aerobically.. (a lot happens to the red blood cell, which you can read a lot more about!) Therefore by the time the red blood cell reaches the veins, most of the oxygen has been used. Hope that helps :)
There are blood vessels in the heart. They are the coronary arteries and veins. The cornary arteries are so important that they come off the aorta before any oxygen rich blood goes to any other part of the body.
circulatory system it provides the oxygen for the red blood cells that come directly from the heart

Oxygen travels into the smallest air sacs of the lungs, called alveoli. Capillaries around these air sacs allow blood to exchange oxygen for unwanted carbon dioxide. The oxygen-rich blood then returns to the heart to be pumped to the rest of the body. The carbon dioxide in the lungs is passed out of the body through the mouth and nose when we exhale. So basically, your lungs have deoxygenated blood while the body has oxygenated blood.
Blood has a job: delivering oxygen. It needs to take it where it's needed, unload, and then come back to the heart and get some more.
Well it usually comes from the pigs heart maybe not always. I don't understand why blood has to come from the heart. I personally think it should come from the lungs. The Co2 should come from the heart. And oxygen should come from trees. I know I'm and idiot dont make fun of me cause i will not kill you. Thank you for listening to my advice or reading. or seeing or smelling
The heart has 4 chambers and blood comes into the heart through 2 of those chambers and exits through the other 2. Oxygen-poor blood enters the heart from the inferior vena cava and superior vena cava, into the right atrium. From there, the blood passes the tricuspid valve and enters the right ventricle. From there, the blood is pumped through the pulmonary valve into the pulmonary arteries and goes to the lungs to dispose of carbon dioxide and collect oxygen. On the left side of the heart, oxygen-rich blood arrives from the lungs via the pulmonary veins where it passes the mitral valve to enter the left ventricle. From there, the blood is pumped through the aortic valve into the aorta.
