The primary source of RBCs in the adult human being is the bone marrow in the shafts of the long bones. T/F

False

Hormone production is a function of blood T/F

False

Antibodies are a formed element of the blood T/F

False (erythrocytes, platelets, leukocytes)

Leukocytosis is a functional characteristic of leukocytes T/F

False (amoeboid motion, diapedesis, positive chemotaxis)

Erythrocytes lack a nucleus. T/f

true

All leukocytes are also lymphocytes. T/F

false

Thromboembolic disorders include embolus formation, a clot moving within the circulatory system T/F

True

The immediate response to blood vessel injury is clotting. T/F

false

The process of fibrinolysis disposes of bacteria when healing has occurred. T/F

False

Positive chemotaxis is a feedback system that signals leukocyte migration into damaged areas. T/F

True

Basophils increase in number when parasitic invasion occurs. T/F

false

Leukocytes move through the circulatory system by amoeboid motion. T/F

False diapedesis

All lymphocytes are leukocytes, but not all leukocytes are lymphocytes. T/F

True

Blood typing for the Kell, Lewis, and Duffy factors is always done before a blood transfusion. T/F

False

RBC's are efficient oxygen transporters because t hey generate ATP by anaerobic mechanisms and do not consume any of the oxygen they carry. T/F

True

Macrocytic anemia is an illustration of iron deficiency seen in individuals who have expanded their blood by increased activity. T/F

False (true is athlete's anemia. Macrocytic anemia is caused by vitamin B12 deficiency.

Each hemoglobin molecule has four polypeptide chains: two alpha chains and two beta chains. T/F

True

Eosinophils are erythrocytes that fight parasitic infection or allergic reaction. T/F

False (Eosinophils are leukocytes that defend the body against parasite infections and lessen the severity of allergic reactions.)

Hemoglobin serves to transport oxygen, but NOT carbon dioxide. T/F

False (About 20% of carbon dioxide is transported bound to hemoglobin.)

Plasma contains water, proteins, nutrient molecules, and hormones. T/F

True

Reticulocytes are sometimes found in circulating blood and are filled with hemoglobin and some ribosomes. T/F

True (Reticulocytes are precursors of RBC.)

The buffy coat in centrifuged blood contains RBC and platelets. T/F

False (The buffy coat contains leukocytes and platelets.)

The RBC count in both men and women is between 5.1 and 5.8 million per microliter of blood. T/F

False (Women have a slightly lower RBC count than men.)

Vitamin D is essential for the synthesis of RBC. T/F

False (B-complex vitamins are essential for the production of RBC.)

When oxygen is bound to hemoglobin it becomes oxyhemoglobin. T/F

True

One of the regulatory functions of blood is to maintain normal temperatures in body tissues. T/F

True

The most abundant component of plasma is protein. T/F

False (The most abundant component of plasma is water.)

Formed elements of blood include erythrocytes, leukocytes, and platelets. T/F

True

Hemoglobin is the protein that makes red blood cells red. T/F

True

Blood cell formation is referred to as hemostasis. T/F

False (Blood cell formation is referred to as hemopoiesis (or hematopoiesis).)

Dissolved proteins are an important part of blood clotting. T/F

True

Blood is NOT important in the regulation of the body's pH. T/F

False (Plasma proteins and bicarbonate ions are very important in maintaining pH.)

Albumin serves an immune system function T/F

False (It has a significant role in regulating plasma osmotic pressure. It also acts as a carrier protein and a blood buffer. Albumin is not an immunological protein.)

The B cell is a lymphocyte T/F

True

The extrinsic pathway of blood clotting is triggered by tissue factor. T/F

true

A free-floating blood clot is called a thrombus. T/F

False Embolus

Hemolytic disease of the newborn (HDN) can develop when an Rh+ woman is pregnant with an Rh- baby. T/F

False Hemolytic disease of the newborn (HDN) can develop when an Rh- mother carries an Rh+ fetus. HDN is unlikely to develop in an Rh- female's first pregnancy with an Rh+ baby. However, HDN can develop in a subsequent pregnancy with an Rh+ baby.

Fetal hemoglobin has a higher affinity for oxygen than does adult hemoglobin. T/F

True

Leukemia refers to cancerous conditions of white blood cells.

True
