if you spin down (centrifuge) a tube of blood and remove the supernatant, and then you spin that supernatant to remove the liquid from the fibrinogen, you will have what liquid?
plasma
serum
saliva
lymph
matching 2 points
match the cell type to its function(s).
erythrocyte (rbcs)
white blood cells
platelets (thrombocytes)
i
immune function and inflammation
carrying oxygen primarily (and carbon dioxide
secondarily)
clotting

Explanation:

• Plasma: When blood is centrifuged, plasma is the liquid part. If fibrinogen (a clot - forming protein) is removed from plasma, it becomes serum.
• Erythrocytes (RBCs): Their main function is carrying oxygen (and also carbon dioxide to a lesser extent).
• White Blood Cells: They are involved in immune function (such as fighting infections) and inflammation.
• Platelets (thrombocytes): They play a crucial role in clotting.

Answer:

• Erythrocyte (RBCs): Carrying Oxygen primarily (and carbon dioxide)
• White Blood Cells: Immune function and inflammation
• Platelets (thrombocytes): Clotting
