Choose the correct statement(s) regarding the composition of plasma. Check all that apply.

-Plasma is mostly water. -The most abundant nitrogenous waste is urea.

Check all that are functions of the blood in the body.

-Transports oxygen from the lungs to body cells -Transports carbon dioxide from the cells to the lungs -Regulates body temperature -Helps maintain normal body pH levels -Helps guard against infection

Check all that are formed elements.

-erythrocytes -leukocytes -platelets

Match the plasma protein with the correct description or example.

1. Albumin (abundance): 58% of the plasma proteins 2. Globulins (abundance): 38% of the plasma proteins 3. Fibrinogen (abundance)- 4% of the plasma proteins 4. Albumin (function)- Regulation of water movement between tissues and blood 5. Globulins (function) -Provide protection against microorganism 6. Fibrinogen (function) -Forms blood clots

Test your basic knowledge about blood with these four True/False questions.

1. Blood and its fibers are a type of loose reticular connective tissue. FALSE 2. The liquid portion of blood is called plasma, and plasma makes up about 75% of the total blood volume. FALSE 3. The total blood volume in the average adult is about 4-5 liters in females and 5-6 liters in males. TRUE 4. Blood makes up about 8% of the total weight of the body. TRUE

Put the life cycle of an erythrocyte in order, beginning with their formation in red bone marrow

1. Erythrocytes form in red bone marrow. 2.Erythrocytes circulate for 120 days in the bloodstream. 3.Erythrocytes are phagocytized in the liver and spleen. 4.Hemoglobin is converted to biliverdin.

Match the CBC measurement with the normal value or range.

1. Female red blood cell count 4.2-5.4 million/microliter 2. Male red blood cell count 4.7-6.1 million/microliter 3. Female hemoglobin count 12-15 g/100mL of blood 4. Male hemoglobin count 14-17 g/100mL of blood 5. Female hematocrit 38-47% of the total blood volume 6. Differential count of neutrophils 55-70% 7. Differential count of eosinophils 1-4% 8. Differential count of basophils .5-1% 9. Differential count of lymphocytes 20-34% 10. Differential count of monocytes 2-8%

Indicate whether each statement is true or false.

1. Glycoproteins and proteins on the surface of platelets allow them to attach to other molecules such as collagen in connective tissue. TRUE 2. Platelets are tiny fragments of cytoplasm and plasma membrane from larger cells called hemocytoblasts. FALSE 3. The platelet cytoplasm contains actin and myosin, which can cause contraction of the platelet. TRUE 4. The life expectancy of platelets is about 120 days, after which they are filtered out of the bloodstream by the kidneys. FALSE

Place the events of the life of a red blood cell in the correct order.

1. Hemocytoblast 2. Proerythroblast 3.Early erythroblast 4. Intermediate erythroblast 5. Late erythroblast 6.Reticulocyte 7.Red blood cell

Indicate whether each statement is true or false.

1. Hemoglobin consists of four heme polypeptide chains and four iron-containing globin groups. FALSE 2. Each heme is a pigmented molecule containing one iron atom. TRUE 3. There are three forms of hemoglobin: embryonic, fetal, and adult. TRUE

Match the plasma protein with its description.

ALBUMIN: Plays a major role in maintaining colloid osmotic pressure GLOBULINS: Consists of α, β, and γ subtypes FIBRINOGEN:Involved in blood clotting

Match the white blood cell with the correct description or function.

NEUTROPHILS: -Nucleus has up to five lobes -Phagocytize microorganisms and other substances EOSINOPHILS: -Attack worm parasites BASOPHILS: -Granules stain blue or purple with basic dyes -Release histamine and heparin LYMPHOCYTES: -Produce antibodies MONOCYTES: -Horseshoe-shaped nucleus -Become macrophages

Match the blood type with the description

TYPE A: Erythrocytes have surface antigen A TYPE B: Erythrocytes have surface antigen B TYPE AB: Erythrocytes have surface antigens A and B TYPE O:Erythrocytes have neither surface antigen A nor B

Platelets are roughly the same size as erythrocytes, and like erythrocytes, they eject their nucleus just before entering circulation.

false

Free bilirubin is transported by the blood to the liver.

true

Iron is transported in the blood by transferrin.

true
