pulmunary artery
heart attack
There is a lot of dark coloured blood. If it was an artery, the blood would be pulsing out, and bright red. Veins carry blood that needs oxygen back to the heart and lungs so oxygen can be replenished. This is why the blood is dark. Well oxygenated blood is bright red (in the arteries)
There is no such thing as an arterial vein. You either have an artery, or a vein. Arteries move blood away from the heart, and veins move blood to the heart. Also, arteries carry blood that contains oxygen to the various parts of the body, whereas veins carry blood that needs oxygen to the heart and lungs.
AnswerThe carotid artery provides the brain with the blood that carries the blood and oxygen.common-carotid-artery-1Blood provides the brain and all of our other organs with the oxygen and nourishment it needs. Blood is kind of like the body's highway, it gets everything where it needs to go.When our heart beats blood is sent to the lungs, then when we breath the red blood cells absorb oxygen, then when our heart beats again the blood is sent around out body like to our arms, legs and brain etc etc. This oxygen is then passed to the different lims and organs.Then the cycle starts again.
The primary function of blood is to carry oxygen from the lungs to the cells of the body. It contains a protein called hemoglobin that bonds with the oxygen in an oxygen rich environment like the lungs and that releases oxygen in an oxygen poor environment such as is found where cells are using oxygen. Some oxygen is also in solution in the blood plasma but this contributes little to meeting the oxygen needs of the body.
The air carries oxygen to your body when it is inhaled into your lungs.The blood carries oxygen through you body to the vcells that use it as part of their metabolism.
arteries carry oxygen This is a trick question ! The answer above is absolutely right in that the arteries transport oxygen to everywhere in the body that might need it. The trick lies in the detail; the oxygen is not transported in the form of a gas. What happens is this. Red blood cells contain a substance called haemoglobin; it's a solid. In the lungs oxygen reacts with this to form oxyhaemoglobin (also a solid). This travels round the arterial system; when a cell needs oxygen it grabs an oxygen atom from a passing red blood cell, at which point haemoglobin reappears in the red cell. The teacher who set this question should be ashamed.
The major blood vessel that needs to be cut when removing a heart during a transplant is the aorta. It is the main artery that carries oxygen-rich blood from the heart to the rest of the body.
The aorta is the largest artery connected to the heart. It needs to accommodate all blood needed for all of the bodies tissues.
Oxygen.
The body needs oxygen to survive, and blood carries oxygen to cells in the body.
It's not really the blood that needs the oxygen. All the living tissues in our bodies needs a steady supply of oxygen, and the blood is what carries that oxygen around and delivers it where it needs to go.
