what is the general function of white blood cells?

They protect you against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health.

They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness. White blood cells are made in the bone marrow.

Functions of blood Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body. Nutrients from the digestive tract and storage sites to the rest of the body.

Phagocytosis is the process by which white blood cells, known as phagocytes, engulf and digest cells - thereby destroying them. These cells may be pathogens such a bacteria. Therefore, phagocytosis is one of the ways by which the immune system can protect the body from infection.

Just as there are many cell types, there are varied cell functions. The generalized cell functions include movement of substances across the cell membrane, cell division to make new cells, and protein synthesis.

Neutrophils make up roughly half of the white blood cell population. They are usually the first cells of the immune system to respond to an invader such as a bacteria or a virus. As first responders, they also send out signals alerting other cells in the immune system to respond to the scene.

Normally, most of our white blood cells are neutrophils. Neutrophils are key infection-fighters and form an important defense against most types of infections. The other types of white blood cells (lymphocyte, monocytes, and macrophages) also help fight infections.

Leukocytes are part of the body's immune system. They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
865246
Monocytes are a type of white blood cell. They help fight bacteria, viruses, and other infections in your body. Along with other types of white blood cells, monocytes are a key element of your immune response.

The spleen has some important functions: it fights invading germs in the blood (the spleen contains infection-fighting white blood cells) it controls the level of blood cells (white blood cells, red blood cells and platelets) it filters the blood and removes any old or damaged red blood cells.

In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).

There are five major types of white blood cells: neutrophils. lymphocytes. eosinophils.

White blood cells include lymphocytes (such as B-cells, T-cells and natural killer cells), and many other types of immune cells. Antibodies help the body to fight microbes or the toxins (poisons) they produce.

White Blood Cells (also called leukocytes) White blood cells protect the body from infection. They are much fewer in number than red blood cells, accounting for about 1 percent of your blood.
