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.

Do the lungs have de oxygenated blood?

It does indeed contain the blood it pumps, but the heart cells themselves receive a rich supply of blood via capillaries. A good rule of thumb is that each contractile cell has one capillary associated with it, since these energy intensive cells need a lot of fresh blood to function.

Does a high white blood cell count specifically indicate bacterial infection?

A high blood cell count that might indicate a bacterial infection is referring to white blood cells specifically. If a bacterial infection is present in the body, the immune system releases into the blood stream additional white blood cells to respond to the threat. A high count of these additional immune cells will then indicate that there is a bacterial presence to which the body is responding.

Is leukopenia an abnormally low number of leukocytes?

A decrease in white blood cells in the blood is known as leukopenia. Leukemia, chemotherapy and many medications can cause leukopenia.
What does low white blood cell count mean

Why does blood have to be filtered?

The kidney does not get filtered. It does the filtering of the blood that passes through it. It removes impurities from the blood, and filters these impurities to the urinary bladder. The filtered blood is sent back into the body to be recirculated. And the impurities are expelled from the body in the urine.

How does hemoglobin enable red blood cells to pick up oxygen then release to other parts of the body?

The haemoglobin helps the red blood cells to the source of the oxygen, like a transport system and then once the red blood cells have the oxygen they then proceed to escort them throught the entire body. the haemoglobin is circulated and then replenished along with the new blood cells through the heart.

What causes white blood cells to rise?

What is estimated in complete blood count?

A complete blood count (CBC) is a fairly broad blood test that is very helpful when you're sick. Your blood is comprised of many different parts. When you're sick it affects the different parts of the blood in different ways. For example, if you have an infection, your white blood cells (your defense system) will likely be higher than normal. Or, if you have been feeling more tired than usual perhaps your red blood cells (which carry iron) are low and you need to take an iron supplement.

Is the hemoglobin content different in calves male and female animals?

Hemoglobin content levels vary from location to location. Calves that live in a higher elevation may have a higher hemoglobin content than calves that live in a lower elevation. Also, male calves tend to have a higher hemoglobin content than females, and differences in breed also provide variances. However each slight is slight to the point where it can be considered insignificant.

According to the journal article below (Clinical and Hematological Studies on Experimentally Induced Selenosis in Crossbred cow calves), the normal hemoglobin content of calves is around 11.92 g/dl.

According to the second journal article below (The Hemoglobin Content of the Blood of Dairy Cattle), the average normal hemoglobin content of calves per 100 cc of blood, regardless of sex or breeding, is 10.46 grams. It is useful to note the key differences of Hb between breeds and between areas where each dairy herd was studied.

Where do veins come from?

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.

What element helps in blood clotting?

Platelets or thrombocytes are a component of blood tissues involved in the formation of blood clots. Platelets are not cells, but are cell fragments.

What is found in the center of a hemoglobin molecule?

Iron is the element found at the centre of haemoglobin.

How does blood infected with bacteria differ from healthy blood?

More white blood cells are produced during an infection

What is the cure for leukemia?

there is actually no cure for leukemia but what can prevent it from getting worse is keep doing exercises and eating right also make sure if you are going to get physical with someone that they have nothing at all because if they do you may worsen and you can end up dying within hours if not treated properly

What substance is transported by hemoglobin?

The hemoglobin molecule is what the oxygen molecule will attach to in the red blood cell.

Are white blood cells the smallest blood cells?

The granule cell of the cerebellum is the smallest cell in the human body, but the red blood cell is the smallest blood cell.

What is the purpose of fetal hemoglobin test?

Fetal hemoglobin (Hemoglobin F), Alkali-resistant hemoglobin, HBF (or Hb F), is the major hemoglobin component in the bloodstream of the fetus. After birth, it decreases rapidly until only traces are found in normal.

How long do you stay on the vegan diet?

I'm vegan for life.

me too!

veganism isn't a diet- its a way of life! its not something like detox which you do to loose weight, you become vegan to end suffering and pollution and cruelty and to become a healthier, happier, kinder person :)

Which gas will be absorbed by the erythrocytes to the exclusion of oxygen?

That would be Carbon monoxide. The blood cells prove that they like Carbon monoxide better by turning even more red.

Carbon monoxide poisoning is often first diagnosed by the person's features being cherry red.

What are some causes of bleeding disorder?

Here are some causes of bleeding disorder:

1. Thrombocytopaenia

There is a deficient number of circulating platelets. Petechiae appears due to spotaneous, widespread haemorrhage. It can be treated with transfusion of concentrated platelets.


2. Impaired liver function

The liver does not have the ability to synthesise procoagulants. This eads to vitamin K deficiency, hepatitis, and cirrhosis.


3. Haemophilia

It includes several similar hereditary bleeding disorers. Haemophilia A is the most common type of haemophilia and it occurs due to factor VIII deficiency. Haemophilia B is due to factor IX deficiency. As for haemophilia C, this condition is mild and occurs to the the deficiency of factor XI.

What is troponin blood test?

Troponin level is a type of blood test used to check for damage to the heart. It is a protein found inside the muscle cells in the heart and is not normally found in the blood stream. If the heart is damaged due to lack of blood flow or oxygen, the muscle cells of the heart begin to break down and release troponin into the blood stream. Since it is not normally found in the blood stream, if the laboratory detects troponin in your blood, it is likely that you have suffered some sort of damage to your heart muscle tissue and need further testing or therapy.

How is bug blood different from human blood?

The former belongs to a human being, and the latter to an insect. Best not to mix 'em up really.

Do earthworms have hemoglobin?

I'm not absolutely sure, but I would say yes, so they can breathe and live like humans.
