Blood
Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

Is it dangerous to have high Erythrocyte sedimentation rate?
A raised ESR indicates that there is inflammation in the system somewhere It will not tell you where the inflammation is or what is causing it. If a elevated ESR is indicated then the next step is to find out what the cause for this is. Often when RA is suspected an ESR test and a rheumatoid factor test is done along with joint X rays to help confirm the diagnosis. It is not necessarily dangerous to have a high ESR however on the other hand it may signal something that could be.
What a sudden change in erythrocyte sedimentation rate mean?
Osinophils are a type of white blood cell usually representing less than 8% of the total white blood cell population. The number of these cells (eosinophil count) with illnesses, such as allergies, asthma, Addison's disease, sarcoidosis, parasite infections, drug reactions, and connective tissue diseases (like rheumatoid arthritis and scleroderma). A high ESR means that there is some sort of inflammation in the system. The ESR is not a test designed to pinpoint the reason for the inflammation. However a high eoeinophil count could explain the high ESR.
Why is erythrocyte sedimentation rate higher in females?
This sedimentation rate in females should normally be under 20, with slight variation depending in the lab doing the testing. 50 indicates that there is some sort of inflammation some where in the body. A sedimentation rate will indicate inflammation, however it does not indicate what is causing it. these test are most often used in monitoring autoimmune disorders such as Rheumatoid arthritis.
ESR stands for erythrocyte sedimentation rate. this is a test that indirectly measures the level of inflammation is in the body.
normal readings are
Adults, Westergren method Women under 50 years old-- less than 20 mm/hr
Women over 50 years old---- less than 30 mm/hr

Where does the exchange of carbon dioxide and oxygen with the blood occur?
it occurs somewhere in the lungs. sorry, i cant get anymore specific than that. sorry, though. :o(
RESPIRATORY
Ericaemily8's improved answer (instead of her's) (The one above mine is someone elses):
It happens at the capillaries, the red blood cells carry the Carbon Dioxide to the capillaries which dispose of it in the human body, that is why you have gas. The capillaries which had oxygen to start with then give the oxygen to the red blood cells which carry it all around your body, mostly your heart.
What is written below is the work of fiction and isn't and never will be backed up by fact. It is the product of a storybook 'The Da Vinci Code'. The author of the below answer obviously cannot separate reality from a movie he saw or a book he read.
According to Leonardo der si Piero da Vinci, the Holy Grail was not a Cup, but actually a Chalice. The Sign of Womanhood. Now, in the Last Supper painting by Leonardo, Jesus, and his Wife, are leaning away from each other, forming a shape in between them. A Chalice, Womanhood.
In the beginning, the Holy Grail was the Cup Jesus had drinken from in the Last Supper, according to Early Christain Mythology Legends. Jesus's Wife, was Mary Magdalene who was preganent with Jesus's Son. When the Romans had Crucified Jesus, Mary fled to another place where she lived the remainder of her life. Even though the Zealots continued to persue her, she was never caught. She died and was laid to rest in a Concrete tomb, located in France. Paris. The Holy Grail isn't a Magical Cup indicating gods powers, no. The Holy Grail is Mary Magdalene's Tomb, indicating, the CHURCH's power. "Holy", being Jesus's Blood, the Grail, a Type of Cup, or Chalice, was Womanhood, Mary Herself. Now, some might question "Just because Da Vinci Painted it, doesnt make it true". That is where the Priory of Sion comes into play. The Priory of Sion, protects the holy Grail, and its power. Da Vinci was, one of the Priory's Members. He belonged to the Sion. The Sion was a Secret Society founded by the Kingdom of Jerusalem in 1099, which preserves the Bloodlines of the Merovingian Dynasty alongside, protecting the Holy Grail. The Sion created the Knights Templar as their Financial Branch and Military Arm.
In May of 2014, Spanish historians claimed that they found the Holy Grail. They believe it is in a church in Northern Spain. If it's not the real thing, you may want to search Rosslyn Chapel in Scotland.
It is not the blood but the veins that "look" blue, and even then it is not the actual color of the vessel. The difference is in the way colored light moves through the tissues, and how the eye perceives those colors of light.
The oxidation state of the iron in the hemoglobin determines it's color; when the blood is oxygenated, the iron's oxidation state changes, changing the color of the blood from dark red to light red. It is never blue.
The changes in blood coloration relate to the respiratory pigment, hemoglobin. Hemoglobin is a topologically complex molecule that very readily binds to oxygen. Once the molecule is fully saturated, it reflects in the crimson red spectrum, and therefore fully oxygenated blood appears to be bright red.
After the hemoglobin molecule gives up its oxygen to tissue that needs it, the molecule becomes much less reflective, and thus deoxygenated blood appears very dark red to purple. But blue is used in charts and diagrams to contrast against red, red being the arterial system bearing O2 and blue being the "deoxygenated" blood in the venous system.
Human blood is always red. It can have different hues of red, but it is still red.
Where does the blood entering the Inferior vena cava come from?
The blood entering the Inferior Vena Cava comes from all your lower body areas... Legs, feet, ect.
What does plasma have to do with a plasma TV?
A plasma panel is a layered device. It is comprised of millions of cells each lined with a red, blue or green phosphor, much like a CRT is coated with the same color phosphor dots. Each cell is filled with a gas and wired to a computer chip that tells it when it needs to light. When the gas is electrified it causes a plasma gas discharge that emits ultraviolet light. That in turn causes the phosphor to glow its color. The complete pattern is scanned in lines from top to bottom in a 60th of a second. (Therefore twice in a 30th of a second which is the time it takes for your eye to comprehend and register any image).
Which blood vessel carries waste-rich blood from capillaries back to the heart?
well form the legs it would be The great saphenous vein and femoral vein that empty into the inferior vena cave, which leads back to the heart
What blood vessel leaves the heart to pick up oxygen?
ARTERIES ALWAYS take blood AWAY from the heart.
How many liters of blood does your heart pumps a day?
About 7,000 liters of blood per day is pumped through the heart of an adult human being.
The amount of blood pumped by the heart changes with activity level
(Stroke volume * heart rate ) = ml/min so if heart rate is 70 beats/min and stroke volume is 120 ml (ml/beat) blood is being pumped by the heart at
75 ml/stroke * 70 beats/min = 5250 ml/min = 5.25 liters/min
5.25 liters/min* 60 min/hour * 24 hour/day = 7560 liters/day but this answer is still wrong as both stroke volume and heart rate are variable.
An average human heart pumps 1,900 gallons (7,200 litres) of blood around the body per day
What organ system brings the blood to the body?
The cardiovascular system brings blood to the body. You have more than 50,000 miles of blood vessels in your body.
What part of the heart acts like doors that control blood flow?
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
What could cause the starter not to work in a 1987 Dodge Dakota 4 cylinder?
Make sure battery is charged. Clean all wire connection at battery & at the starter. Make sure trans is in neutral or park completely or clutch pedal is completely depressed (check if neutral switch is ok) If no response from these check out solenoid, starter 7 innition switch & all wires/connectors in starting circuit. Here is another thing to look for-make sure the ground strap is connected to block & frame/body. Check the fuse & relay. They are located in the fuses box on the fender well in the engine compartment
The chambers that receive blood into the heart?
left and right atriums, and the left and right ventricles
wrong its just the left and right atrium the ventricles (left and right) pump out the blood
the receiving parts of the heart are the auricles. . eep
The answer is atria, not capillaries.
atria
What tube in your body moves blood from your heart through your body?
I think the answer is blood vessels. I hope I was right. :)
What describes the next step after the blood has traveled from the heart to the toes?
The blood returns to the heart through veins.
Does blood ever flow backwards in the heart?
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.
Did plies the rapper get arrested?
I can't speak on if Plies has or doesn't have a criminal record, because I don't know him personally, however MOST rappers nowdays who claim they have a criminal record really don't, and sooner or later they get exposed for pretending they live out a certain lifestyle that they know they really don't.
Anyways, I'm a fan of Plies music, I think he makes good music, so regardless of if he has a criminal record or not, I'm still a fan of his music and will continue to listen to it as long as I enjoy it.
What prevents backflow of blood in the heart?
valves in the veins.
AV (Atrioventricular) Tricuspid between the right atrium and ventricle, Bicuspid (Mitral) between the left atrium and ventricle,
Semilinar valves = pulmonic valve between the right ventricle and the pulmonary trunk, Aortic valve between the left ventricle and aorta
