blood transports oxygen and nutrients
Lumen
The aorta is the blood vessel with the widest lumen. In contrast, capillaries are the blood vessels with the narrowest lumen.
The three items that the blood transports includes nutrients, oxygen, and metabolic waste.
The blood in the villi is referred to as villous blood or villous capillary blood. It plays a vital role in absorbing nutrients from the small intestine after digestion and transport these nutrients to the rest of the body.
Double-lumen PICC lines come in two colors. Red is the blood access lumen or arterial lumen and blue is the blood return lumen or venous lumen. Despite the names, neither lumen is leads to an artery, but both lead into a vein.
Your blood does this; IE; your Cardiovascular system.
called lumen
The Vasa Vasorum supply the wall of the large arteries This method to feed the smooth muscle is necessary as the endothelium covering the lumen doesn't permit the ready diffusion of nutrients from the lumen.
blood vessels carry/distribute blood and nutrients throughout body.Blood vessels carry blood round the body, to and from the heart.Blood stores oxygen and nutrients to be distributed throughout the body, and blood vessels are their means of transport. the function of the blood vessels is to transport blood to all part of the body.The blood vessels carry the oxygen rich blood to the cells, and the carbon dioxide and wastes away from them. They act sort of like channels through which the nutrients can flow.
In the intestines, cells use active transport to pump nutrients such as glucose and amino acids from the intestinal lumen into the bloodstream. In the kidney, cells actively transport ions and small molecules from the blood into the nephron tubules for excretion in urine. In nerve cells, active transport is used to maintain the concentration gradients of sodium and potassium ions across the cell membrane, essential for nerve signaling.
