What are the 3 types of blood?

Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma:

• Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken.
• Red blood cells carry oxygen.
• White blood cells ward off infection.

How many types of blood cells are there?

Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid component of blood.

Why low white blood cell count is bad?

The main risk of an abnormally low white blood cell count is how vulnerable it may make a person to infection. Without an adequate white blood cell response available to fight infection, the body is at greater risk that any infection (including those usually regarded as minor) may cause serious illness or death.

What percentage of blood is white blood cells?

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.

What are the 7 types of blood cells?

If you had no white cells, you would get lots of very serious infections . White blood cells can find germs that enter your body and destroy them, which keeps them from making you sick. Some white blood cells make antibodies, which are special molecules that can stick to germs and make them harmless. White blood cells also help repair damaged tissue, which is important in wound healing.

What would cause low white blood count?

Medical conditions that can cause low white blood cell count are aplastic anemia and some autoimmune diseases that can destroy WBCs . Other causes include myelodysplastic syndrome, hyperthyroidism, inflammatory conditions like rheumatoid arthritis, and liver or spleen disorders.

What are the symptoms of low blood cell count?

Other symptoms of a low red blood cell count may include dizziness (particularly when standing), shortness of breath, headaches, pale skin, chest pain, and coldness in the hands or feet.

What is the job of a white blood cell?

White blood cell. The job of white blood cells (also called leukocytes ) is to fight infections and cancer. They also remove poison, waste and damaged cells from the body.
