What are the three basic kinds of formed elements in blood and what are their respective functions?
Formed Elements consist of Erythrocytes (red blood cells that function in oxygen transport), Leukocytes (white blood cells that function in immunity), and Platelets (cell fragments that function in blood clotting).
What are the three formed elements in the blood quizlet?
The three formed elements of blood are: white blood cells (leukocytes), red blood cells (erythrocytes) and platelets (thrombocytes ).
What are the 3 unusual features of the formed elements of blood?
What are unusual features about the formed elements? – Only White Blood Cells are complete cells. – Red Blood Cells have no nuclei or other organelles. – Platelets are cell fragments that help control bleeding.
Where are the formed elements of blood produced?
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 is the main formed element in blood?
Formed Elements. The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).
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.
What are functions of formed elements?
The formed elements of the blood include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Of these, leukocytes are primarily involved in the immune response. All formed elements originate in the bone marrow as stem cells (HSCs) that differentiate through hematopoiesis.
Which determines the blood type of a person?
Blood types are determined by the presence or absence of particular antigens on the surface of red blood cells. There are eight main blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive and O negative. The positive and negative refers to your Rh type (once called Rhesus).

red blood cells. … platelets. white blood cells.
What is the function of RBC?
What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
What are the blood components?
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets.
Which blood cells are responsible for fighting infections?
White blood cells (WBCs) fight infections from bacteria, viruses, fungi, and other pathogens (organisms that cause infection). One important type of WBC is the neutrophil.
What makes the blood look red?
