It means that you ''go down'' and are about to die. In the case of the Hot Zone, the victims of Ebola litterally bleed out through throwing up blood and leaking blood from all of there body orifaces, especially the rectum.
It travels to the right ventricle passing through the tricuspid valve. Then it travels to the lungs via pulmonary arteries. The oxygenated blood from the lungs returns to the heart (into the left auricle). From the left auricle the blood travels to the left ventricle. The left ventricle pumps it to aorta. The blood travels through the arteries and veins, then it returns to the right auricle of heart.
Answer1 while passing through the heart it recieves the charge from the nodes of the heart answer2 during the formation of sodium and potasium ions the charge is produced in the plasma and so in this mechanisim charge is produced in the plasma of the blood
White blood cells are found in the blood vessels. Having said this, one remarkable adaptation of WBCs is their ability to squeeze out of capillaries. This means they don't have to rely on microbes passing through the bloodstream; the WBCs can go directly to the source of the pathogens.
That mean it contain old blood as if from oesophagus,stomach and upper small intestine.
No. Bleeding from the rectum after the biopsy is normal. This is due to the needle passing through the wall of the rectum; it may strike a blood vessel causing some bleeding or it may not. Also, you may notice a small amount of blood in your urine. This should clear up after a day or two. You may also see blood in your semen. This can last a week or longer. The presence of blood or lack thereof does not indicate cancer.

Hypoperfusion!
The upper rectum receives its blood supply from branches of the inferior mesenteric artery from the abdomen

It flows round the body, passing blood through your body. It goes through the vessels, collects oxygen and lets the oxygen go in the cirlculation system. :)
