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.

How many white blood cells are in the human body?

The average adult has between 4,000 to 11,000 white blood cells per microliter of blood. The total number of white blood cells in the body can vary depending on individual factors such as age, health status, and stress levels.

For what type of fitting would the application of solder wire during the jointing process be required intgral ring or capillary or type a or type b?

The application of solder wire during the jointing process is typically required for integral ring fittings or capillary fittings, as these types of fittings use soldering as the method to create a secure connection between the pipes or components. Type A or Type B fittings usually do not require soldering for jointing.

What is the clear liquid in the blood?

The clear liquid in blood is called plasma, which makes up about 55% of the total blood volume in the body. It contains water, electrolytes, proteins, hormones, and waste products, and plays a crucial role in transporting nutrients, hormones, and waste products throughout the body.

What is the indication of increased white blood cells on cervix?

It could just mean that there is an infection around the cervix or it could mean something greater. You have to wait for the Pap tests to come back but women often have inflammation of the cervix. Your doctor might prescribe an antibiotic prior to the test results if she or he feels that an infection is present.

Do white blood cells form antibodies which help you become immune to certain diseases?

Yes, white blood cells produce antibodies in response to foreign substances like viruses or bacteria. These antibodies can recognize and neutralize specific pathogens, helping the immune system become immune to certain diseases by identifying and attacking them upon future exposure.

How do you strelise blood agar?

You can't sterilize blood as it would hemolize. Blood is sterilized aseptically when it is purchased-meaning the animal (lets say a sheep) is killed in a certain way to ensure this happens. So the blood in your blood agar plate has already been aseptically sterilized

What is the function of the cell nucleus?

The cell nucleus is the "control center" of the cell and controls the metabolic and reproductive functions of the cell

Contains the genetic information needed for protein synthesis and regular cell function.

Contains the genetic information needed for reproduction.

How do you produce fake blood?

If you are on a low budget, Corn Syrup and Red food coloring would work the best. it's a great combination for low budget movies, class films, or even just messing around with your friends. ---- More:

To make your own fake blood, here are some other methods depending on the type of blood you need (use amounts/proportions according to eye):

Fresh or spurting blood from arteries or flowing from capillaries (like when you cut your finger) is bright red because it has its hemoglobin carrying lots of oxygen in it and that makes it more red. Make it by mixing red food coloring in white (clear) corn syrup.

Old pooled blood gets thicker and darker. Make it by mixing the red food coloring in the corn syrup and then add chocolate syrup.

Older blood that is spattered or not pooled is a little thinner than pooled and thickened blood, so make that mixture as above with the chocolate syrup and then add a little water to thin it.

Fresh flowing blood from veins has less oxygen than arterial blood and it is also carrying some wastes from the body's cells that make it darker. But, it is not blue like is often incorrectly indicated, even sometimes in school. It is darker red but it is a "cooler" shade of red, and that can be made using some blue in the mix. Make it like the pooled blood with food coloring, corn syrup, chocolate syrup and then a small amount of liquid detergent (like dish washing liquid) that is a blue color just to get a glossy darker dirty red.

But, when you add the detergent, you can't use it for blood to come out of your mouth, so instead of the detergent, when you want to have the blood come from your mouth or be on your face, use honey. So what you'll have in your mouth is corn syrup, honey, food coloring and chocolate syrup.

To make alien blood that is green or blue, just substitute the green or blue food colorings for the red.

Which human blood group lacks proteins in the red blood cells?

Blood type O lacks the antigen proteins of A and B. Blood type O is the universal donor.

How does m protein help streptococcus pyogenes evade phagocytes?

M protein is a surface protein on Streptococcus pyogenes that can prevent phagocytes from recognizing and engulfing the bacteria. This evasion tactic allows the bacteria to evade the host immune response and persist in the body.

Why can't human blood be used in a gorillas body?

Gorillas have a different blood type than humans do. If you inserted the blood into a gorilla, the gorillas immune system would see the human blood as a foreign object and attack it, making the gorilla very sick. This happens even between humans! When blood transfusions are made in hospitals, doctors have to be very careful that the recipient has the smame kind of blood as the donor so the patients body doesn't react.

How are red and white blood cells alike?

== == Platelets: surface when you get cut and clogs the bleeding (scabs) white blood cells: fight against bacterias and viruses

red blood cells: Carry "food" and oxygen == ==
their both in your body, they both can only be seen through a microscope, their both cells(blood), they both benefit your body, and you need them both to survive that's all i could think of
All i know about red blood cells is that they are part of your first line defence. White blood cells on the other hand are your second line of defence and they find diseases/pathogens and find them, some may just 'eat up' the pathogens but others will make antibodies which put antigens on the pathogens and kill them.

That is what i think as i have just done about it in science! Year 8
well it is quite obvious whrn you think about it.............THEY ARE BOTH CELLS. see the simplist way of doing it just think what they both have in common plus blah blah blah blah blah!EASY!!tfjtfhbdgffhg

What is meant by unexpected antibody in human blood?

An unexpected antibody in human blood means that a person does not have the antigen required to make a certain antibody because it is foreign to them. Unexpected antibodies are usually alloantibodies.

What would happen if you placed an human red blood cell in a hypotonic environment?

hypotonic solution will cause the blood cell to swell up and maybe lyse or be destroyed.

Hypotonic solution contains low solute and high water concentration.

To reach equilibrium or blanace the difference in the cell and out side of the cell water will move in to make the solute in the cell equal the solute outside the cell

What are the largest blood cells?

Blood is a type of vascular fluid,so it cannot be termed as big or small.It has two main components namely plasma and corpuscles(blood cells).The blood corpuscles are of three types-erythrocytes(red blood cells)

leucocytes(white blood cells)

thrombocytes(the platelets).

If question is about the largest blood corpuscle,the answer is (leucocytes)white blood corpuscles.

Produced by bones?

Bones are involved in the production of red and white blood cells in the bone marrow, as well as storing minerals like calcium and phosphorus. This process is crucial for maintaining proper bone density, immune function, and overall physiological health.

What makes a nerve cell good at its job?

The nerve cell is good at its job because it is very long, and is branched out across the body. It is also well insulated so that electrical impulses can pass quickly to the Central Nervous System.

How is oxygen transported in the blood?

Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.

Organic chemistry is the study compounds containing what element?

Organic Chemistry, is a branch of chemistry in which carbon compounds and their reactions are studied. A wide variety of classes of substances-such as drugs, vitamins, plastics, natural and synthetic fibers, as well as carbohydrates, proteins, and fats-consist of organic molecules. Organic chemists determine the structures of organic molecules, study their various reactions, and develop procedures for the synthesis of organic compounds. Organic chemistry has had a profound effect on modern life: It has improved natural materials and it has synthesized natural and artificial materials that have, in turn, improved health, increased comfort, and added to the convenience of nearly every product manufactured today.------------------------------------------------------------------------------------------------------------ Horse Isle - Carbon -DaveyBoy on bay/brown sever

Is blood organic?

Yes, blood is considered organic because it is composed of organic molecules such as proteins, lipids, and carbohydrates. It is a complex mixture of cells and fluids that play essential roles in our body's functions.

Can pennicillian lower progestrerone levels in the blood?

There is no known direct interaction between penicillin and progesterone levels in the blood. Penicillin is an antibiotic that works by targeting bacteria, while progesterone is a hormone involved in regulating the menstrual cycle and pregnancy. If you have concerns about medication interactions, it's best to consult with a healthcare provider.

What are the two basic kinds of cells?

The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.

What shape are red blood cells?

Spherical bi-concave disc. This shape is due to the absence of a nucleus.
a red blood cell is like a disc with a dent in the middle.it is known to be a cell without a nucleus.however,young red blood cells do have a nucleus,just as the grow older,they loose it.blood contains hemoglobin which contains iron which gives blood its metalish smell.however in rare cases,the red blood cell is shaped like a sickle due to chromosomes,resulting in what we call sickle cell anemia
Biconcave Disc Shape
it is kinda shaped like a doughnut but the center isn't totally gone
The shape of RBC (Red Blood Cells) are Biconcave disc-shaped cells
You can see pictures by following the related links below.

A general description though: a mint with a slightly indented middle on both sides....

That's so that it can carry oxygen to the cells...
A red blood cell is shaped like a concave disc. In easier terms it's shaped like a doughnut but without a complete hole in the middle.

A red blood cell that is spiky and misshapen shows signs of sickle-cell anemia.
red blood cells are elliptically shaped cells which have a conaved middle from both sides how ever there are many types of cells the discussed above is the most common one
a biconcave disc

How long for entire blood supply to be filtered?

A person's kidneys receive about 20% of the heart's cardiac output (~1200mL/min). A person has about 6 - 8L of blood depending on gender, body size, etc. So on average it will take about 5 - 7 minutes for a person's entire blood volume to reach the kidneys.

But once the blood reaches the kidneys, it is the glomeruli that filters the blood. The average glomerular filtration rate (GFR) is 125mL/min or 180L/ 24hr. So it takes about 45 min - 1 hour for 6 - 8L of blood to be filtered.
