Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets.
What are the 7 formed elements of blood?
- Erythrocytes (red blood cells) Erythrocytes, or red blood cells, are the most numerous of the formed elements. …
- Leukocytes (white blood cells) Leukocytes, or white blood cells, are generally larger than erythrocytes, but they are fewer in number. …
- Thrombocytes (platelets)
What are the elements found in the blood?
Blood is composed of formed elements—erythrocytes, leukocytes, and cell fragments called platelets—and a fluid extracellular matrix called plasma. More than 90 percent of plasma is water.
What elements are in red blood cells?
RBC element levels are very useful for:
- Cardiotonic influences (magnesium, potassium)
- Anti-inflammatory processes (selenium, copper, zinc)
- Anemia (copper, iron)
- Immunological function (zinc, copper, magnesium)
- Glucose tolerance (chromium, manganese and possibly vanadium)
Which element is important in the formation of blood?
Formed blood elements involve erythrocytes, leukocytes and thrombocytes. They can be separated from blood plasma using centrifugal force. Figure shows that the most descended are erythrocytes – the volume of erythrocytes in a sample of blood is called the hematocrit.
What is the largest formed element in blood?
Monocytes: They are the largest of the formed elements. Their cytoplasm tends to be abundant and relatively clear. They function in differentiating into macrophages, which are large phagocytic cells, and digest pathogens, dead neutrophils, and the debris of dead cells.
What makes up 41 of blood?

Which metal is present in blood?

Which element is not found in blood?
Chromium is the component which isn’t found in blood.
How blood is formed in our body?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
What are two main components of blood?
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.
Which element can damage the blood?
When the oxygen concentration is low, RBCs tend to become distorted and “sickle” shaped. These deformed cells can block small blood vessels and damage the organs they are supplying.
What are the three functions of the 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.
