Intestines are the biological pipes or Plumbing through which your food and drink travel through after having sit in the stomach for a while. The entire journey of the food and drink through the digestive tract breaks down the food into parts that can be absorbed into the blood stream.
Hydrochloric (stomach) acid, pepsin, trypsin, bile, and so on are used by the body to cause the breakdown of the food so that the nutrients and liquid can be used in the body to maintain health of all the cells in the body.
The food and drink are moved through the piping system by peristaltic waves that systematically contract, then expand the diameter of the biological piping so as to induce a rhythmic flow of the food and drink. The vitamins, sugars, minerals, oils, and other nutrients are part of the body's metabolic system of energy production that permits the cells of the body to continue living. Once the broken down nutrients, etc, have passed through the selectively permeable intestinal wall, they can be circulated by the blood stream to most parts of the body to nourish all of the cells to prevent their death.
If this system should encounter a problem, and it malfunction, the gastrointestinal tract usually gets blocked or springs a leak in some way, and doctors refer to this as a metabolic system breakdown or malfunction or illness or disease.
Ducts from the gallbladder and the pancreas feed into parts of the intestines to supply the bile and enzymes that help digest and breakdown the food and drink into forms that are usable in the blood. Different sections of the intestines contain different types of enzymes, so different sections of the intestines specialize in absorbing different types of vitamins, nutrients, and minerals. If certain sections are removed by surgery, then certain vital food components needed for health will be missing, unless those sections somehow re-grow themselves with time (as sometimes can actually happen).
Professor John Beard surmised that cancer was partly caused by a deficiency of the pancreatic enzymes trypsin and chymotrypsin. People on diets rich in animal meat were losing the preventative effects of these enzymes because the latter were being constantly employed to break down these animal proteins. These pancreatic enzymes were shown by Beard to strip down and digest the protein coating of cancer cells. It was this life-saving action that was described by the Edinburgh embryologist in his Unitarian or Trophoblastic Thesis of Cancer.
No, vascular tissue is not composed of red blood cells and white blood cells. Vascular tissue is made up of vessels that transport blood throughout the body, while red and white blood cells are components of blood itself. The vascular tissue includes arteries, veins, and capillaries.
The cardiovascular system consists of:The heart (the pump)The blood vessels (arteries, capillaries and veins which form a network around the body)Blood (fluid medium)
bloodcells, skin cells, white blood cells
The plant you are describing is likely a dicot, such as a dandelion. Dicots have leaves with branched veins, taproots, and stems made primarily of collenchyma, parenchyma, and sclerenchyma cells.
Red blood cells are part of the circulatory system
The thick layer of a vein is made of collagen, wrapped in bands of smooth muscle while the interior is lined with endothelial cells called intima.

Carbon dioxide, made by the cells as they do their work, moves out of the cells into the capillaries, where most of it dissolves in the plasma of the blood. Blood rich in carbon dioxide then returns to the heart via the veins.
You probably mean what do veins do? Anyways, they always return blood back to the heart.
Blood cells are made in bone marrow.
Red marrow is where RBCs are made mainly in the flat bones such as hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the proximal ends of the long bones femur and humerus. They then go to the blood itself.
Veins, in most animal circulatory systems, carry deoxygenated blood from the tissues back to the heart.The exception are the pulmonary veins, which carry oxygenated blood to the heart.There is also a lining inside the veins made of epithelial tissue.
BLOOD.
Blood and veins and bones. -aysha
they did not have blood they had a substance called"ichor' flowed in their veins
Mainly, they're made out of the same tissues in the same order, the difference being how thick those tissues are, a lot thicker in arteries than in veins. They're both responsible for blood flow, being the arteries responsible for blood flow from the heart to the tissues and veins responsible for blood flow from the tissues to the heart.
