Which part of the human body doesn't get oxygen from the blood?

Lungs ~ it comes through the mouth and nose doesn't it?

the major parts of circulatory system are heart and blood vessels.\nthe blood vessels are of three types-1. arteries \n2. veins\n3. capillaries\nthe arteries carry blood mainly oxygenated blood from heart to different parts of the body.\nthe veins carry deoxygenated blood from all parts of the body to heart.\ncapillaries connect the arteries and veins...they are thin walled and allow the exchange of gases to occur across their walls.

well, let's think.\nwe have more oxygen than needed. the bronchiolar arterioles are the places where blood cells pick up oxygen. we don't need more oxygen, so we want less blood cells to pick it up. we want less blood cells - we constrict the arteriole, so less blood cells can get through, and...viola.

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

Well break the words down. Capillaries are closer to the surface of the skin, that is where gases exchange and where waste is disposed of. Veins are a little deeper and have more pressure on them, they are returning blood back to the heart.\nSee you have arteries, veins, and capillaries.\nThe arteries are the pipes going out of the heart, they have the most pressure on them. Because they have to deliver all the blood with the o2 in it to the capillaries all over your body. After the gas exchange at the capillary level, it then turns in to your veins, that return to the heart.

Single cell organisms don't have blood. Blood is a transportation system, bringing O2 and nutrients to cells, whilst taking away CO2 and waste. Since a Single cell organism can get what it needs from its immediate surroundings, it does not need a transport system, so it does not need blood.

breathing is just lungs.  respiration has to do with the blood getting oxygen.\n\nand there are 2 types of respiration too.  one with chemistry.  not sure about that one.

YES , OUR BLOOD CONTAIN Hemoglobin or haemoglobin (frequently abbreviated as Hb) is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. Hemoglobin transports oxygen from the lungs to the rest of the body, such as to the muscles, where it releases the oxygen load. IRON IS A CONDUCTOR OF ELECTRICITY

I don't believe that guy called her a moron for giving the right answer. Yes blood without oxygen is blue but it may appear green due to you looking at it through your skin. I'm sure you've seen someone with blue lines on their body. When blood becomes oxygenated...the Fe is pulled to the center of the heme ring. It's actually this conformational change that produces the red color. Not rust. Also to comment. The Fe is contained within the porphyrin ring but not in a flat structure. It is partially off center and is pulled more equally within the ring structure with the addition of oxygen. If you looked it up you'd know I wasn't making **** up. Although i do apologize for the blue comment. But we see blue because of the absorption of light at the surface of our skin. At least while the blood is stil in circulation. You need to be less critical. Yes all of them are red but to the naked eye under the skin they clearly appear blue. It's not total "bullocks" for someone to assume such. The intelligent should learn to be teachers not arrogant tactless shrews.

Yup, oxygen oxidises our bodies. As we are carbon based lifeform, we lose carbon when we breathe out - hence, carbon dioxide.

The red blood cells have a special oxygen transport molecule called hemoglobin. It has an iron atom in the middle of it that binds to the oxygen very loosely in the lungs where oxygen is plentiful. Then, when the red blood cell reaches tissue that has a low oxygen concentration, the loosely bound oxygen dissociates from the hemoglobin, ready to be used by the cells in the body.\n\nThe right side of the heart pumps blood to the lungs where the oxygen is picked up. Then the blood goes back to the left side of the heart to be pumped out to the rest of the body so the oxygen can be delivered.

In order for your heart to pump well, it needs oxygen, and it obtains it from the coronary arteries that are connected to the aorta. \nCoronary arteries - like any other organ or tissue, the heart needs oxygen. The coronary arteries that supply the heart are connected directly to the aorta, which ensures a rich supply of oxygenated blood.

Our brain functions tell our heart to pump, it pumps blood throughout your body, when your heart stops pumping, it cuts off circulation to the brain and to the tissues in your body.  Without blood circulation, your cells in your body degenerate.  Your degeneration will start with rigamortis (makes your body turn cold and stiff).  After day 3, your body starts to swell up and deteriorate. The soul is not a physical part of your body but a mental part of your mind.

hemoglobin carries oxygen and crosses the placenta from mother to child.  they don't actually breathe until they are born, until that time their oxygen comes from their mothers.

The brain requires oxygen to function. Without oxygen, the brain cells deteriorate. Yes people with hypoxia say strange things and do weird stuff. Their thinking is definitely impaired. You can help this person with hypoxia by getting more iron and folic acid into their system. This helps speed the blood to the brain and blood carries oxygen. Also at low levels of oxygen, they can not perform surgery, if they do they risk the patient having a stroke.

its where the blood picks up the oxygen.

Blood does not need oxygen to be red.  Blood is never blue.  Just because a hose is green, it doesn't mean the water coming out will be green as well. (referring to veins)
