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.

In most states driving while intoxicated is defined as having a blood alcohol concentration of?
.8 percent
Is blood thicker or thinner in winter?
Blood is thicker in the winter, which prevents heat loss. Conversely, it is thinner in the summer, which allows more heat to escape, cooling the body. This is while a 60 degree day in October feels a lot colder than a 60 degree day in February.
Why does your daughter have blood in her poop?
Please go to ER immediately. You could be bleeding internally and losing more blood than you are seeing. It could be from an ulcer, but many other things can cause this as well. This is serious, please don't fool around because you are afraid.
What is the most abundant cellular component of whole blood?
The cellular components of blood include red corpuscles (erythrocytes), platelets (thrombocytes), and five types of white corpuscles (leukocytes). Of these, erythrocytes are the most common (37- 54%).
What is RBC Count in Haematology blood test for humans?
A red blood cell, (the cells that Give blood its distinctive red colour). A red blood cell's (erythrocyte) function is to carry haemoglobin around the body. Haemoglobin carries oxygen which is required for cellular respiration
An RBC count is used in a variety of tests in the diagnosis of disease
They are normally confined to blood vessels, which is specialized to transport oxygen. When mature, red blood cells are biconcave discs, which lack a nucleus and contain hemoglobin. Women have about 4 million to 5 million erythrocytes per cubic millimeter (microliter) of blood and men about 5 million to 6 million; people living at high altitudes with low oxygen tension will have more. The RBC reference range 4.5-5.9 (x1012/L) in males and 3.8-5.2 (x1012/L).
What is normal hemoglobin for 6 year old?
Normal levels of hemoglobin reading in children is 11 to 16 g/dl, grams per deciliter.
What should white blood count be?
At least you have to get your blood clotting time measured. You can ask the lab to check your International Normalised Ratio (INR). The count should be in the range of 2.0-3.0, the target is 2.5. If applicable, you can do it monthly.
What may cause a slightly elevated white blood cell count?
Many things. It could be related to a short-term illness such as the cold or flu, or it could be linked to a chronic condition like an autoimmune disease. It is best to check with your doctor.
Basically your white blood cells are there to fight infection...if you have an increased count, your body is probably fighting something. It is definitely better to have that checked out by a doctor because you never know if it could be something serious.
What type of air that lungs put into blood cells?
Oxygen, but most of the oxygen you take in will probably get breathed out again, depending on wether or not you are exercising, and how hard you are exercising.
it's not much of an elaboration, if that's what you were going for, but I tried.
How does blood flow back to the heart from the kidney?
the deoxygenated blood from the kidneys is carried by venules which combine to form veins. These veins then bring the deoxygenated blood to the heart via. the anterior and superior vena cava. This blood is then poured to right atrium of heart and it is then passed to right ventricle via. tricuspid valve.
Platelets, or thrombocytes, are the smallest formed element in the blood. Made of cell fragments, platelets are part of the blood clotting process. Non-formed clotting factors also are critical to blood clotting.
thrombocytes
What are the two general major components that go into makeing up of blood?
Plasma is the liquid component of blood that we see when we get a cut. This plasma is made up of red blood cells, white blood cells and platelets.
Does donating blood weaken the immune system?
When donating blood, you do not give enough blood to significantly reduce the number of white blood cells in your system. Those that are lost are quickly replaced in a healthy individual. And individuals with already weakened immune systems are not permitted to give blood.
What would happen without plasma in your blood?
The brain would not get oxygen, and the body would not get food, and different organs would not be connocted correctly. all in all, blood is a major part of the body parts functioning together (besides nerves). Without blood, you would die.
What is the task of white blood cells?
White blood cells (WBCs), or leukocytes, are a part of the immune system and help our bodies fight infection. They circulate in the blood so that they can be transported to an area where an infection has developed. In a normal adult body there are 4,000 to 10,000 (average 7,000) WBCs per microliter of blood. When the number of WBCs in your blood increases, this is a sign of an infection somewhere in your body.
Here are the six main types of WBCs and the average percentage of each type in the blood:
- Neutrophils - 58 percent
- Eosinophils - 2 percent
- Basophils - 1 percent
- Bands - 3 percent
- Monocytes - 4 percent
- Lymphocytes - 4 percent
Most WBCs (neutrophils, eosinophils, basophils and monocytes) are formed in the bone marrow. Neutrophils, eosinophils and basophils are also called granulocytes because they have granules in their cells that contain digestive enzymes. Basophils have purple granules, eosinophils have orange-red granules and neutrophils have a faint blue-pink color. When a granulocyteis released into the blood, it stays there for an average of four to eight hours and then goes into the tissues of the body, where it lasts for an average of four to five days. During a severe infection, these times are often shorter.
Neutrophils are the one of the body's main defenses against bacteria. They kill bacteria by actually ingesting them (this is called phagocytosis). Neutrophils can phagocytize five to 20 bacteria in their lifetime. Neutrophils have a multi-lobed, segmented or polymorphonuclear nucleus and so are also called PMNs, polys or segs. Bands are immature neutrophils that are seen in the blood. When a bacterial infection is present, an increase of neutrophils and bands are seen.
Eosinophils kill parasites and have a role in allergic reactions.
Basophils are not well understood, but they function in allergic reactions. They release histamine (which causes blood vessels to leak and attracts WBCs) and heparin (which prevents clotting in the infected area so that the WBCs can reach the bacteria).
Monocytes enter the tissue, where they become larger and turn into macrophages. There they can phagocytize bacteria (up to 100 in their lifetime) throughout the body. These cells also destroy old, damaged and dead cells in the body. Macrophages are found in the liver, spleen, lungs, lymph nodes, skin and intestine. The system of macrophages scattered throughout the body is called the reticuloendothelial system. Monocytes stay in the blood for an average of 10 to 20 hours and then go into the tissues, where they become tissue macrophages and can live for months to years.
Neutrophils and monocytes use several mechanisms to get to and kill invading organisms. They can squeeze through openings in blood vessels by a process called diapedesis. They move around using ameboid motion. They are attracted to certain chemicals produced by the immune system or by bacteria and migrate toward areas of higher concentrations of these chemicals. This is called chemotaxis. They kill bacteria by a process called phagocytosis, in which they completely surround the bacteria and digest them with digestive enzymes.
How do white blood cells leave the blood stream?
Bone - surprising to many people - is vascular, which means it has a plentiful access to blood. So, since it has blood vessels running though it, especially the spongy bone at the ends of long bones, it is quite easy for the blood cells that form in red bone marrow to find their way into the blood stream.
How long can you survive without red blood cells?
Look i don't know ok. why do you want me to answer it. this is the dumbest site ever. Wikianswers Bla Bla Bla. Yesterday i wrote who is the president of the united states and Wikiaswers told me george bush wrong da its obama. i have never seen that much stupdity. This site is amerian for pite sake. take this as advice, DO NOT TAKE ANY ANSWERS FROM THIS SITE BELEIVE ME IT WILL BE WRONG!!!!!!!!
HOW HIGH CAN YOU COUNT BEFORE YOU USE THE LETTER A?
Technically I guess i could count to about 5 million. That is: if for the next 55 odd years I incremented my count by 1 every second. That means I would never sleep, eat, drink or anything else for the next 55 years.
So if anyone tells you they can count to higher than 5 million, they are probably PHYSICALLY incapable of doing so
i still think the answer he was looking for was 27 but thank you for your thoughts!
Oh! Oh! I can count high, watch! One, two, three, four, f- umm ok dunno what comes after that. But i can count to 10 in German! =D
How is sickle cell hemoglobin different from normal hemoglobin?
The difference is that a patient with sickle cell disease has an increased level of one specific type of Hemoglobin, that is Fetal hemoglobin or HbF. However, the amount of total hemoglobin is the same.
Will aspirin cause blood in the urine?
Blood in the urine should be investigated by a doctor, not some random person on the internet. Aspirin is a blood thinner, but whether it is causing the urinary problem is something an expert needs to decide.
What percent of blood loss is needed to cause shock?
A healthy adult has 5 Liters of circulating blood and another 500 ml as reserve in the spleen. Loss of up-to 500 ml of blood will not usually produce any tachycardia or hypo-tension unless fear of blood loss occurs in an otherwise healthy person.
Why blood is unique as a tissue?
blood itself is considered a tissue. however its main difference and i guess its most striking characteristic is that its ability to flow from one place of the body to the others by way of the blood vessels. it also has the ability to transport important substances which the body needs in order for it to survive. --thoughtfulobserver
