Blood

Red blood cells have a life span of about 120 days. They are formed in the bone marrow and destroyed by the reticuloendothelial cells present in spleen, liver, lymph nodes, brain, the heart or even in the muscles. Spleen is the major site of their destruction.

Plasma donations can be given at the Society of the Precious Blood. Society of the Precious Blood is located at 689 South Ave, Rochester, NY.

External Nares (Nostrils) --> Nasal Cavity --> Inferior, Superior, & Middle Nasal Conchae --> Pharynx --> Larynx --> Trachea --> Primary Bronchi (Left & Right) --> Hilus --> Bronchioles --> Respiratory Bronchioles --> Alveolar Ducts --> Alveoli (the grape-like sacs) --> the the "spider web" of Pulmonary Capillaries.

I'm pretty sure its something like calcium or iron... but you better check, just in case

It is iron, because when exposed to oxygen, it turns red because together they form rust. This is also why blood has a metalic taste.

Red cells are more numerous.

Dissolved gases and ions

the 287 hemoglobin units in a chimp are the same 287 hemoglobin units in a human. Humans did evolve from the chimp as did the gibbon,orangutan,gorilla and monkey. These animals cannot exchange blood with a chimp because it would kill them. They are not the same species because they evolved from the chimp.Humans did not evolve from the chimp because they have the 287 identical hemoglobin units as a chimp. The common chimp, the bonobo and the human have identical hemoglobin along with 98.4% same DNA. Go weigh it out.

You should be able to go to the bathroom without blood in your stool. However, if you do see some don't be alarmed. In most instances the blood doesn't indicate anything serious. It Is typically do to hemorrhoids or a tear in the lining of your anus. Some more serious reasons for blood in the stool include, Colon polyps, colon cancer, Colitius, and diverticulitis.

The presences of a large number of white bloods are usually a good indicator of infection due to the fact that white blood cells fight off pathogens. If a wound becomes infected that means that bacteria, viruses, fungi, or any other type of foreign body then white blood cells rush to the site to try and prevent the infection from spreading. This is sometimes how doctors are able to see if there is an underlying problem with a patient, such as an infection. They take blood samples and see the concentration of white to red.

It depends on your doctor and your age, for the most part yes you will of you are over about 14-15 years old

It is hemoglobin that is the oxygen transport substance in blood. Wikipedia has some good information on this metalloprotein, and a link is provided.

Melanin darkens skin. It is also responsible for photoprotection, ie resistance to ultraviolet light-induced skin damage. This is achieved by rapidly converting incoming ultraviolet light into heat, which is much less likely to cause problems like free radicals. Thus, sunlight exposure tends to stimulate melanin production.

It is slightly above normal for most labs but it may still be normal for some individuals.

Starting in the right atrium, the blood flows through the tricuspid valve to the right ventricle. Here it is pumped out the pulmonary semilunar valve and travels through the pulmonary artery to the lungs. From there, blood flows back through the pulmonary vein to the left atrium. It then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta. The aorta forks, and the blood is divided between major arteries which supply the upper and lower body. The blood travels in the arteries to the smaller arterioles, then finally to the tiny capillaries which feed each cell. The (relatively) deoxygenated blood then travels to the venules, which coalesce into veins, then to the inferior and superior venae cavae and finally back to the right atrium where the process began.

Meticulous infection control techniques are the best defense against sepsis. It is caused by a massive invasion of the body by bacteria or other organisms or toxins. This infection is body wide and can be very difficult to control under some instances. For eample massive trauma of the hand, car accidents or even extensive surgery.

Platelets are the small cells in your body that stick to the wall of a blood vessel following injury. They clump together and prevent bleeding. If you have low platelets in your blood, or thrombocytopenia, your ability to form clots and stop bleeding may be impaired. Therefore, there are some things you should know about living with low platelets.

A substance that prevents or slows the clotting of blood is called an anticoagulant.

Anemia is any condition in which the oxygen-carring capacity of blood is less than that required by the body.

The white blood cells

The primary function of platelets is to from blood clots. The formation of these blood clots help to control bleeding so there is not too much blood loss.

To form a blood clot, platelets clump together using fibrinogen as an adhesive.
