Which is the hematological function of platelets?
- Carrying oxygen
The primary function of red blood cells (RBCs), or erythrocytes, is to carry oxygen.
- Preventing blood loss
The primary function of platelets is coagulation per clotting factors; therefore, platelets play a role in preventing blood loss.
- Protecting against infection
The primary function of white blood cells (WBCs), or leukocytes, is to protect against infection.
- Ridding the body of carbon dioxide
Ridding the body of carbon dioxide is primarily the function of the respiratory system; however, the circulatory system and red blood cells (RBCs) carry carbon dioxide for this to occur.
There are three primary types of blood cells within the body: red blood cells (RBCs), white blood cells (WBCs), and platelets.
Platelets are small colorless disk-shaped cell fragments without a nucleus. They are found in large numbers in blood and are involved in clotting. Due to the role that platelets play in the clotting process, one primary function is preventing blood loss.
