• preventing infection

• transporting hormones and waste

• all of these are functions of the cardiac system

All of the following are formed elements of the blood except

• a platelet

• hemoglobin

Blood plasma is mostly made of

• water

• granules

• oxygen

• hemoglobin

This cell is respohnsible for releasing histamines, which dilate blood vessels during an allergice attack. How is it categorized and what is it called?

• granulocyte; lymphocyte

• agranulocyte; monocyte

• granulocyte; basophil

• agranulocyte/eosinophil

A single hemoglobin molecule can carry how many oxygen molecules? A red blood cell can carry how many hemoglobin proteins?

• 4 oxygen molecules; millions of hemoglobin proteins

• millions of oxygen molecules; four hemoglobin proteins

• 4 oxygen molecules, 100 hemoglobin proteins

• millions of oxygen molecules; 100 hemoglobin proteins

Because oxygen is nonpolar

• it must be absorbed by the lymphocytes

• it must diffuse dirrectly into the blood

• it must be eliminated quickly

• it must be carried by hemoglobin
