What is the arrangement and cell morphology of the streptococci?
Streptococci are spherical bacteria that typically arrange themselves in chains or pairs due to their division in one plane. They are characterized by their cocci shape, which can vary in size but generally remain small. This arrangement is a result of the incomplete separation of daughter cells after binary fission, leading to their distinctive chain-like formation.
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.
Does blood cells contain fibers?
Blood cells do not contain fibers in the same way that connective tissues do. However, blood does contain fibrinogen, a protein that can form fibers during the clotting process, leading to the formation of a clot. Red blood cells, white blood cells, and platelets, which are the primary components of blood, do not possess fibrous structures themselves.
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.
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.

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.
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

Are blood cells capable of renewing themselves?
Red blood cells (RBCs) have a life span of 120 days. More are always being made.
Are red blood cells found in the structure of a synovial joint?
No. Not by themselves. They will be inside the tiny blood vessels.
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

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.
