what are the functions of blood?

to carry nutrients, oxygen, wastes to/away from body cells.

Based on the 2 conditions above, there are 4 functions.\n\nDigestive:\n\n * Production of Bile\n\nBile contains bile salts which help emulsify lipids (fats) into small oil globules.  Remember, Bile does not digest fats.  It 'chops' up fat in to smaller molecules so as to increase the surface area for enzymatic reactions.--> faster\n\n\n\nExcretory:\n\n * Deamination of excess protein (amino acids)\n\nThe toxic amino group is removed, converted to urea and is passed to the kidneys to be excreted.\n\n\n * Breakdown of red blood cells\n\nAlthough most of the breakdown of the RBCs occur in the spleen, products from the RBCs are sent to the liver for storage purposes.\n\n\n* Detoxification\n\nSolid matter are broken down by phagocytosis.  Bio-chemical conversion of soluble substances (e.g. drugs, alcohol) into harmless substances

The primary function of hemoglobin (Hb) is to transport oxygen. Since oxygen is not very soluble in water (the major constituent of blood), an oxygen transport protein must be used to allow oxygen to be 'soluble'. Hemoglobin (Hb) is the oxygen transport protein used in the blood of vertebrates. Below is a wireframe diagram of a hemoglobin molecule. It is composed of 4 polypeptide chains (represented in this diagram by different colors. Each chain contains one heme group (colored orange), each of which contains one iron ion (not shown). The iron is the site of oxygen binding; each iron can bind one O2 molecule thus each hemoglobin molecule is capable of binding a total to four (4) O2 molecules.

The liver has a bunch of functions. Not only does it help to filter things out of the blood, but it also produces cholesterol and stores extra energy that is released to the muscles as glycogen (a kind of carbohydrate). It also plays a role in digestion by interacting with the gall bladder, which is attached to it, but I don't remember exactly what the liver does in that case.

Blood provide 2 functions for all of the cells in your body. It brings nourishment to it such as vitamins, minerals, water, and oxegyn. It also carries the waste created by the cells away. Just like every human creates waste, such as fecal matter and urine, every cell also creates waste. The blood carries the waste away and takes it to elimination organs such as the bowel, skin, kidneys, and the lungs.

Its like getting your blood removed... Plasma=whole blood - blood cells. Plasma gives volume to blood, makes it fluid and allows blood cells to circulate (among other numerous functions). Loss of body liquids thickens blood by lowering the volume of plasma (which consists primarily of water), and thats how people die from dehydration... or vampire bites ;)

Blood's role in the body is three fold: First, it acts as a transort system for nurtients and such to reach the different parts of the body. Secondly as a defence system, where lymphocytes are active in controlling pathogens that enter the body (such as bacteria, viruses, fungi, etc). Lastly, the blood acts as a sealant. When there is damage to the body, the platelets in the blood seal up the wound.\n\nBlood is very important to the body. Without it, you wouldn't exist.

blood, fluid pumped by the heart that circulates throughout the body via the arteries, veins, and capillaries (see circulatory system; heart). An adult male of average size normally has about 6 quarts (5.6 liters) of blood. The blood carries oxygen and nutrients to the body tissues and removes carbon dioxide and other wastes. The colorless fluid of the blood, or plasma, carries the red and white blood cells, platelets, waste products, and various other cells and substances

1.  removal of dead blood cells\n2. stores platelets\n3. produces blood cells during fetal life.\n \n(p.s.  the "liver" metabolizes carbs, lipids, protein, processes drugs and hormones, excretes bilirubin, synthesizes bile salt, stores glycogen, phagocytize red blood cells, and activates vitamin D, Rodney)

Its like gas for a car. Blood is a oxygen carrier, and supports all the body organs. If anyone loses too much of it- too bad!

The spleen is a gland that is associated with the circulatory system, where it functions in the destruction of old red blood cells in holding a reservoir of blood.

No research is going on very fast. At laboratory stages artificial blood is already formed.Soon we will synthesize it in yhe lab.Blood substitutes are used to fill fluid volume and/or carry oxygen and other gases in the cardiovascular system. Although commonly used, the term is not accurate since human blood performs many important functions. Red blood cells transport oxygen, white blood cells defend against disease, platelets promote clotting, and plasma proteins provide various functions. The preferred and more accurate terms are volume expanders for inert products, and oxygen therapeutics for oxygen-carrying products. Examples of these two "blood substitute" categories:\nVolume expanders: inert and merely increase blood volume. These may be crystalloid-based (Ringer's lactate, normal saline, D5W (dextrose 5% in water)) or colloid-based (Haemaccel, Gelofusin). \nOxygen therapeutics: mimic human blood's oxygen transport ability. Examples: Hemopure, Oxygent, PolyHeme. \nOxygen therapeutics are in turn broken into two categories based on transport mechanism: perfluorocarbon based, and hemoglobin based.\nVolume expanders are widely available and are used in both hospitals and first reponse situations by paramedics and emergency medical technicians. Oxygen therapeutics are in clinical trials in the U.S. and Europe, however Hemopure is more widely available in South Africa.

The heart is what pumps blood and is the centerpiece of the circulatory system. Without it the blood could not carry the nutrients the body needs. The lungs take in oxygen to help feed the bloodstream. Basically both organs do the same job, just in different ways and for the same end. Keeping YOUR blood infused with the nutrients the body requires to sustain itself. Hope this helps.

Blood plasma, red blood cells, white blood cells, platelets, and numerous nutrients that are being delivered to various parts of your body.  \n\nStructurally speaking, the circulatory system is a complex set of arteries drawing blood away from your lungs and to every part of your body (including the brain and heart muscle), veins drawing blood toward your lungs, the heart that pumps to keep blood moving, and capillaries that drop of oxygen to cell tissue in exchange for carbon dioxide.

r.b.c is Red Blood Cell.Red blood cells perform the most important blood duty. A single drop of blood contains millions of red blood cells which are constantly traveling through your body delivering oxygen and removing waste. If they weren't, your body would slowly die.
