What blood cell in the kidney secrets bed blood cells?
Cells within the kidney called interstitial fibroblasts produce a substance called erythropoietin, EPO for short, that stimulates production of red blood cells. They doesn't secrete or produce red blood cells themselves. Red blood cells are produced within bone marrow.
Is white blood cells a virus or bacteria?
White blood cells are normal parts of the human body. They are neither viruses nor bacteria.
What is hemolytic streptococcus?
Hemolytic streptococcus is a group of bacteria that can cause various infections in humans, including strep throat, skin infections, and invasive diseases such as pneumonia and sepsis. These bacteria can be classified into different groups based on their hemolytic properties (alpha, beta, or gamma) when grown on blood agar plates. Beta-hemolytic streptococci are known for producing toxins that cause the breakdown of red blood cells.
Do white blood cells clean themselves after attacking bacteria?
No. They just "eat" them just as you would if you ate a sandwich.
What cells would not divide using mitosis?
Cells that do not divide using mitosis include red blood cells (erythrocytes) and neurons in the brain. Red blood cells lack a nucleus, and neurons undergo a different process called mitotic division or neurogenesis to replace themselves.
Why do alpha streptococci produce a green color on blood agar?
All of the different streptococci are organized into three groups based on how they break down red blood cells, a process called hemolysis. The group of streptococci that perform alpha hemolysis are called alpha streptococci. In alpha hemolysis, the hydrogen peroxide produced by the streptococci oxidizes the blood's hemoglobin, turning it into methemoglobin, which is green in color.
Why do alpha streptococci produce green color on blood agar?

How does the white blood cells ability to change to affect its function?
white blood cells can squeeze themselves in between other cells, to reach other, infected cells
What type of medium is blood agar?
Blood agar is media rich in reb blood cells and the most commonly used type of media is horse blood media. It is useful for the isolation of bacteria such as Streptococci or organisms that would not readily grow on media that lack red blood cells. For the isolation of Streptococci it is also useful in observing alpha and beta haemolysis.
Are red blood cells found in the structure of a synovial joint?
No. Not by themselves. They will be inside the tiny blood vessels.
Are blood cells capable of renewing themselves?
Red blood cells (RBCs) have a life span of 120 days. More are always being made.
Why is the bone marrow is important?
because it produces red blood cells since red blood cells cant reproduce themselves because they lack a nucleus
How does streptococci pneumonia affect and attack cells?
well basically it affects yo wee wee

What move materials past cells or move cells?
Blood moves materials past cells, allowing for diffusion. It also moves cells themselves to places they are needed, as with immune system cells.
How does oxygen get in blood?
There are little sacs called Alveoli in the lungs. In these sacs are where gasses are exchanged. Oxygen molecules attach themselves, from the air we breathed in, to the red blood cells, while carbon dioxide molecules unattach themselves from red blood cells and are carried away in the air we exhale.
Are blood cells produced by mitosis or meiosis?
No. Meiosis is when a cell produces a haploid, which is a cell with only half the number of chromosomes. Meiosis is only used for making cells used for reproduction. Red blood cells are created by mitosis, which is when cells make two copies of themselves and split into two identical cells.
