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.

Why is protein hemoglobin different from protein insulin?
They are two different proteins, like the difference between a train and a robot.
The difference between one protein and the other is the amino acid sequence that comprises that protein and the molecular bonding that determines its shape. Shape determines function in a protein. If it loses its shape it can't do its job. The shape of insulin and hemoglobin is different so insulin binds with glucose and hemoglobin binds with oxygen.
What is considered a lymphocyte count?
What about a range of 22.2-43.6% as a normal range for lymphocytes, and the number is 47.6%, would this be considered abnormally high?
What blood cell is ancestral of platelets?
Platelets are derived from the fragmented cytoplasm of megakaryocytes, which are large cells found in the bone marrow. They contain the necessary components to form platelets, including granules and microtubules. Platelets play a crucial role in blood clotting and wound healing.

What hormone helps with the maturing of white blood cells?
The hormone that helps with the maturing of white blood cells is called colony-stimulating factor (CSF). CSF is responsible for stimulating the production and maturation of white blood cells in the bone marrow.
Do platelets assist with clotting?
Platelets are not cells, but cell fragments, that help plug any holes in the blood vessel, acting in combination with other factors in the blood, such as fibrin, during clotting to prevent excessive bleeding.
What the function of platelet?
The function of platelets is in clotting. Without them the blood would not clot. They are cell fragments and not cells. They live only 5-9 days.
Too many platelets can cause clots that then can travel and cause blockages in vessels. Too few can cause uncontrolled bleeding.
What ABO agglutinogens are present on the red blood cells of MrGreen's blood?
Mr. Green's blood type could potentially have A and B agglutinogens present on his red blood cells if he has blood type AB, have only A agglutinogens if he has blood type A, only B agglutinogens if he has blood type B, or no agglutinogens if he has blood type O.
Is red blood cell membrane an excitable tissue?
No, the red blood cell membrane is not an excitable tissue. Excitable tissues are able to generate and conduct electrical impulses, which is not a function of red blood cells. Red blood cells are primarily involved in transporting oxygen and carbon dioxide in the bloodstream.
How long does it take for all of the red blood cells in your body to be replaced 10 times?
Red blood cells have a lifespan of about 120 days. If it takes about 120 days for all red blood cells to be replaced once, then it would take approximately 1200 days (120 days x 10) for them to be replaced 10 times in your body. This is roughly equivalent to 3.3 years.
Can o negative receive o negative blood?
No, unless there has been a genetic mutation in one of the parent; They are B, but a mutation makes them appear to be O --> link between sugar and blood cell is missing so appear O ( the absence of sugar on the blood cell)
DNA can be mixed through a process called recombinant DNA technology, where DNA from two or more different sources is combined to create a new genetic combination. This can be done in the lab using enzymes like restriction enzymes and DNA ligase to cut and paste DNA fragments together. The resulting mixed DNA can be used for various purposes in genetic engineering and biotechnology.
How do white blood cells increase body temperature?
White blood cells release chemicals called cytokines when they detect an infection in the body. These cytokines signal the brain to increase body temperature as part of the immune response to help fight off the invading pathogens by creating an unfavorable environment for their growth. This increase in body temperature is known as a fever.
What do red blood cells do to help heal a cut?
Red blood cells do not play a direct role in healing a cut. Their main function is to carry oxygen from the lungs to the rest of the body and remove carbon dioxide. Platelets and other components of the blood are involved in the clotting process to stop bleeding and initiate the healing cascade.
Are there 25 trillion red blood cells in an adult's body?
Yes. An adult has about 20-30 trillion red blood cells.
What component in the plasma of red blood cells carries oxygen molecules to the somatic Cells?
Hemoglobin is the component in red blood cells that carries oxygen molecules to the somatic cells in the body. Hemoglobin binds to oxygen in the lungs and releases it in tissues where it is needed for cellular respiration.
How long do you have to stop drinking alcohol to pass blood lab work?
The amount of time needed to pass blood lab work after stopping drinking alcohol can vary depending on factors such as frequency and quantity of alcohol consumption, overall health, and the specific tests being conducted. Generally, it is recommended to abstain from alcohol for at least 24-48 hours before undergoing blood tests for accurate results. It's always best to consult with a healthcare provider for personalized guidance.
What parts of blood assist in clotting?
People can be genetically predisposed to having blood clots, or thombosis (single) or thombi (multiple).
However, most incidents of thrombosis relate to a combination of lifestyle factors, including:
- prolonged immobility - in a car, in an airplane, or due to other illness or disability. People who sit for long hours or who are bedridden have a higher risk of developing thrombi.
- decreased fluid intake - which thickens blood
- smoking - which thickens blood
- underlying narrowing of blood vessels - due to high fat intake, for example
A blood clot begins when the one or more RBCs become "sticky". As the RBCs travel through smaller veins, especially in the legs, the stickiness makes one or more adhere to the vessel's wall, like a pimple. As more sticky RBCs pass over the pimple, some of them stick to the already stuck RBCs, making a sort of speed bump in the vessel. This process of stickiness continues, making the clot grow larger and longer. If noticed early, the clot remains small(ish), more like a misshapen ball. But many times, the clot just keeps adding RBCs to the mass. As it fills the vessel, it begins to make a longer clot typically following the blood's direction of flow. So a clot that forms in the calf grows longer up to the knee... up to the thigh... and so on. These are often referred to generically as "clothesline type" clots. They are one long mass that nearly completely obstructs blood flow in that area.
Swelling is one of the first symptoms people notice, along with pain in the calf. Redness and warmth follow, especially when the limb is in a dependent position. Swelling can increase dramatically when standing because the blood cannot force its way past the clot. Pulmonary embolism (PE) can quickly follow.
What activities before donating blood would cause facility to deny you?
Activities such as traveling to certain countries with high risk of infectious diseases, recent tattoos or piercings done in unregulated settings, recent drug use, or certain medical conditions like low hemoglobin levels or high blood pressure can all be reasons for a blood donation facility to deny someone from donating blood.
What organ breakdown red blood cells and synthesizes urea?
The liver is responsible for breaking down red blood cells and synthesizing urea as part of the body's waste removal process. The breakdown of red blood cells releases hemoglobin, which is processed by the liver to form a substance called bilirubin. This substance is then converted into bile, which contains waste materials like bilirubin and cholesterol and is excreted from the body.
What would stop red blood cells from being produced?
well they're produced in the bone marrow, and if you have something wrong with your bone marrow then i guess that would result in less red blood cells being produced.
in the bone marrow there is pluripotent hematopoietic stem cells which produce many different types of blood cells ( including red bloodcells) and if there was a problem ere then this would also cause there to be less red blood cells ( which are very important as the carry oxygen around the body)
hope this helped ;)
The condition characterized by an inadequate number of circulating red blood cells is known as hypoproliferative anemia. This can be caused by various factors such as nutrient deficiencies, bone marrow disorders, or chronic diseases.
Is anemia a common disease in the white blood cells?
Anemia is not a disease in white blood cells; rather, it is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood. Anemia can be caused by various factors such as iron deficiency, vitamin B12 deficiency, or chronic diseases. White blood cells are responsible for fighting infections and are not directly related to anemia.
