The composition of blood is

Reduced red blood cell numbers cause

Which of the following formed elements carry oxygen?

Hematocrit and packed cell volume are synonymous terms

A reticulocyte count can indicate to a physician the rate of leukocyte formation

Oxygen deficiency increases RBCs numbers by increasing the secretion of erythropoietin by the kidneys

The life span of circulating RBCs is about 10 - 12 days

Heme is broken down into iron and amino acids for use in the synthesis of new RBCs

Plasma is a pale yellow fluid that accounts for more than half of the blood volume

Serum is whole blood minus the clotting elements

Synthesis of plasma proteins occurs in the spleen

The mature erythrocyte does not contain ribosomes, mitochondrias, and other organelles typical of most body cells

The final step in RBC formation is called erythropoiesis

A person with antibody A in his or her plasma would have which blood type

Type AB blood is considered to be the universal recipient.

Blood does not normally contain the anti-Rh [blank_start]antibodies[blank_end] but they may appear in the blood of an Rh-negative mother during certain circumstances.

Which of the following substances is not found in serum?

Which of the following substances is not found in blood plasma?

An allergic reaction may increase the number of

What is a blood clot that is moving through the body called?

What is the primary function of hemoglobin?

Are any of the following steps not involved in blood clot formation?

Classification of leukocytes that contain cytoplasmic granules: [blank_start]granulocytes[blank_end] Most numerous leukocytes: [blank_start]neutrocytes[blank_end] Granulocytes that release heparin and histamine: [blank_start]basophils[blank_end] Granulocytes that protect against infections from parasitic worms and allergic reactions: [blank_start]eosinophils[blank_end] Agranulocytes that produce antibodies: [blank_start]lymphocytes[blank_end] Agranulocytes that can enter tissue spaces as macrophages: [blank_start]monocytes[blank_end] Cell fragments that function in blood clotting and hemostasis: [blank_start]platelets[blank_end] Cells from which platelets are formed: [blank_start]megakaryocytes[blank_end] Classification of leukocytes without cytoplasmic granules: [blank_start]agranulocytes[blank_end] Classification of formed elements that are nucleated cells lacking hemoglobin: [blank_start]leukocytes[blank_end]
