Red blood cells in blood carry oxygen throughout the body. The actual chemical substance in red blood cells that carries oxygen is hemoglobin. Hemoglobin also carries carbon-dioxide when passed through capillarys, the part where the carbon dioxide is exchanged with the oxygen. capillaries are a cell thick for the lower blood presure.

What substences does the blood carry out?

What are the substances carried by blood and their functions?
Blood carries oxygen through out your body. Your lungs inhale oxygen and the blood cells carry the oxygen to your heart. Then the heart makes more blood cells to carry more oxygen to pump more blood.
Are veins tiny blood vessels that allow substances to pass between the blood and body tissues?
No, capillaries are what allows substances to go from the walls of the small intestine into your cells. Veins are what carry the blood (with cells inside) to the heart to be oxygenated.
What are the names of the three blood vessels that carry blood around the body?
There are three blood vessels. 1. Arteries - these blood vessells carry blood away from heart to the cells of the body. They have a pulse and they are walled with elastic fibres. 2. Veins - Carry blood from the other parts of the body to the heart. They have valves to stop backward flow of blood. 3. Cappilaries are only one cell thick in reality, and they help to diffuse substances from the blood to the cell through the cell membrane (which is selectively permeable). They diffuse useful substances to the cell, and diffuse waste substances out. Hope that helps ;)
What does blood carry - and where does the exchange of substances take place?
Blood carries oxygen, nutrients, hormones, and waste products. The exchange of substances between blood and body tissues occurs in the capillaries, which are tiny blood vessels with thin walls that allow for the transfer of molecules. Oxygen and nutrients are delivered to tissues, while waste products are picked up and taken away by the blood for disposal.
Which structure contains blood vessels that carry nutrients and oxygen from the mother to the embryo?
The umbilical cord contains blood vessels which carry substances to and from the placenta and thence from the mother.
What is blood composed?
Blood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen, white blood cells fight infections, platelets help with blood clotting, and plasma is the liquid portion that carries cells and nutrients throughout the body.

What are characteristics of blood?
Three types of blood vessels are found in the human body: arteries, veins, and capillaries. Arteries typically carry oxygenated blood away from the heart with the exception of the pulmonary arteries, which carry deoxygenated blood to the lungs. Veins carry deoxygenated blood back to the heart. Capillaries are the smallest blood vessels and they allow various substances such as oxygen, carbon dioxide and nutrients, to pass from the bloodstream into the tissues of the body.
