White blood cells help your body fight infections. Platelets help your blood to clot. Blood cell disorders impair the formation and function of one or more of these types of blood cells.
What is the difference between red blood cells and platelets?
Red blood cells are complete cells, whereas platelets are considered as cell fragments. Red blood cells constitute more than 99% of total formed-element volume, while platelets constitute less than 1% of it. Red blood cells contain hemoglobin, while platelets lack hemoglobin. Platelets are smaller than red blood cells.
What type of cell is platelets?
A tiny, disc-shaped piece of cell that is found in the blood and spleen. Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They help form blood clots to slow or stop bleeding and to help wounds heal.
Why are my white blood cells and platelets low?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.

What are the functions of red blood cells?
Red Blood Cells. Blood has three main functions: transportation, regulation and protection. Our erythrocytes, or red blood cells, are the most abundant cell type in the human body. Additionally, erythrocytes are anucleated, which means they don't have a nucleus.
What is the most abundant type of white blood cell?
Neutrophils are the most abundant type of white blood cell in our body. These are primarily responsible for killing off foreign bacteria. Neutrophils are the first responders when we are injured or sick, and they help keep us healthy by phagocytizing (or consuming) bacteria in our bodies.
What is the matrix of blood cells?
The blood matrix surrounding the cells is known as plasma, which accounts for about 55% of our blood volume. There are three types of living cells in blood: red blood cells (or erythrocytes ), white blood cells (or leukocytes) and platelets (or thrombocytes ). These make up the remaining 45% of our blood volume. {"error":true,"iframe":true}.
How many types of leukocytes are there in the human body?
The types of leukocytes in the blood. There are five different types of white blood cells, or leukocytes, in our bodies, and we can break them up into two main categories. These are granulocytes and agranulocytes. These terms simply refer to how these cells look when stained.
What are the two cells that help us transport?
Red blood cells (or erythrocytes) are the tool our bodies use for transportation, and white blood cells (or leukocytes) are responsible for keeping us free of disease and healthy. Finally, platelets (or thrombocytes) are responsible for clotting our blood when we have a cut or open wound. Learning Outcome.
How does blood help us maintain homeostasis?
Blood also helps us maintain homeostasis by regulating our internal body pH and temperature as well as how much water is in our bodies at a given time. Plasma, our connective tissue matrix, is about 90% water. Blood is also vital in protecting our bodies.
What is the last blood component that is involved in protection?
Platelets. The last blood component, which is involved in protection, is platelets, or thrombocytes. These are small, irregularly shaped cells, which do not have a nucleus. These cells contain fibrinogen, which helps our blood to clot and helps our skin form scabs when we're cut. Lesson Summary.
What is the cellular portion of blood?
The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting. Click to see full answer.

How do platelets form a plug?
When a blood vessel is damaged, platelets accumulate at the damaged site and form a plug by sticking to one another and to the surrounding tissue. Platelets are approximately 3µm in diameter; very much smaller than the other formed-elements like red and white blood cells.
What are the cells that pinch off from white blood cells called?
Platelets. Platelets are considered as cell fragments that pinch off from larger cells called megakaryocytes, the precursor to white blood cells found in bone marrow. Platelets are colorless and have granular cytoplasm. These fragments play an important role in blood coagulation, which prevents excessive blood loss.
What percentage of the formed element volume is made up of red blood cells?
Red blood cells constitute more than 99% of the formed-element volume, while the rest (less than 1% of total formed element volume) constitute both white blood cells and platelets. Both red blood cells and platelets are formed in the red bone marrow and destroyed by phagocytosis.
What is the function of blood?
