White blood cells, or leukocytes (also spelled "leucocytes," "leuco-" being Greek for white), are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Five[1] different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. Leukocytes are found throughout the body, including the blood and lymphatic system.[2]
The number of WBCs in the blood is often an indicator of disease. There are normally between 4×109 and 1.1×1010 white blood cells in a litre of blood, making up approximately 1% of blood in a healthy adult.[3] An increase in the number of leukocytes over the upper limits is called leukocytosis, and a decrease below the lower limit is called leukopenia. The physical properties of leukocytes, such as volume, conductivity, and granularity, may change due to activation, the presence of immature cells, or the presence of malignant leukocytes in leukemia.

What does the MARROW produce?
The marrow produces blood cells in the body, including red blood cells, white blood cells, and platelets.
What are two main kinds of cells in blood?
The two main kinds of cells in blood are red blood cells, which transport oxygen throughout the body, and white blood cells, which help the body fight infection and disease.
Compare white blood cells with red blood cells?
White blood cells are part of the immune system, defending the body against infections and diseases, while red blood cells transport oxygen to tissues throughout the body. White blood cells can move independently, whereas red blood cells circulate in the blood vessels. White blood cells are less numerous than red blood cells in the bloodstream.
How many white blood cell are there for every 600 to 800 red blood cell?
There are 500 white blood cells to every 1000 red blood cells (or you could say there is double the amount of red blood cells). The answer would be 200 red blood cells for every 100 white blood cells.
Are there more white blood cells or red blood cells?
There are more red blood cells than white blood cells in the body. Red blood cells are the most abundant type of blood cell and are essential for transporting oxygen throughout the body, while white blood cells play a crucial role in the immune system.
Why does your body need red blood cells and white blood cells?
Red blood cells carry oxygen to the cells in your body while the white blood cells fight diseases.
Where are the white blood cells in the body?
In blood of the body
How many white blood cells do you have going around in your body?
there are about 6000-9000 WHITE BLOOD CELLS in your body
What are white blood cells?
Hi there! white blood cells are little cells in our body that help eradicate viruses and other harmful things in our body. (just in case you want to know about these cells as well) Red blood cells are what transport oxygen throughout our body.
What blood cells fight germs that enter the body?
White blood cells tend to gobble up germs. White blood cells flock to areas of irritation and infection in order to fight them off.
Is oxygen delivered to the cells of the body by white blood cells or red blood cells?
Red blood cells transport oxygen throughout the body. White blood cells aid in the fight against infection.
Where are most of the White Blood Cells in the human blood?
White Blood Cells are found everywhere in the body including blood and lymphatic cells.
What are the blood cells that protect the body from infection?
White blood cells
What does the MARROW produce?
The marrow produces blood cells in the body, including red blood cells, white blood cells, and platelets.
What are the two kinds of blood cells inside your body?
White blood cells and red blood cells.
What are two main kinds of cells in blood?
The two main kinds of cells in blood are red blood cells, which transport oxygen throughout the body, and white blood cells, which help the body fight infection and disease.
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.
