Blood is a liquid which is a type of connective tissue. Blood is made up of blood cells and the liquid from the blood (plasma). Two main functions of substances from the blood into cells and immunity to infectious agents such as bacteria, transport and is a component viruses.Blood cardiovascular system. Blood flows through the body to the heart and blood vessels.
Blood is composed of several components. The major component of blood beef ared blood cells, white blood cells and platelets.
Plasma contains nutrients, sugars, fats, hormones, gases and waste to be transported in the blood. blood plasma levels of about 55 percent of volume.Plasma blood consists of water with dissolved substances. The plasma contains salt, proteins and blood cells.
Red blood cells (erythrocytes)
red blood function is oxygen to tissues and cells distribution members and absorb carbon dioxide for transport to the lungs of body.These cells determine blood type and is the cell type abundant in blood cells blood.Red They have what is called a double-concave shape is known. Red blood cells have a nucleus, but to millions of hemoglobin molecules contained. These proteins containing oxygen molecules bind iron in the lungs receive and transport to various body parts.
White blood cells (leukocytes)
white blood cells function in the immune system and defense of the lymphatic system of the body against infection. Quote this cell, destroy and remove pathogens and foreign bodies out of the body. There are several types of white blood cells, each having different functions. Examples include lymphocytes, monocytes, neutrophils, basophils and eosinophils.
Platelet function in the clotting process. When platelets encounter a damaged blood vessels, which are grouped together to close the wound in the blood vessels. These cell components are formed from portions of cells in the bone marrow.
The blood cells produced in the bone marrow. The mother of the bone marrow that develop in the red blood cells, blood cells and platelets white blood cells. blood cells have a variety of tire life. Red blood cells circulate for about 4 months, platelets about nine days, and white blood cells ranged from a few hours to several days. The production of blood cells, it is often determined by the body structure, such as lymph nodes, spleen, liver and kidneys. If the oxygen in the tissues is low, the body responds by stimulating the bone marrow to produce extra red blood cells. When the body is infected, white blood cells are produced.
