BME 235 Exam 3 Questions and Answers
Verified by Experts
List the three major classes of plasma proteins. Which one is absent from blood serum? 1.
Albumin (responsible for maintaining blood osmolarity)
2. Fibrinogen- (important in blood clot formation) -absent from blood serum
3. Globulin- carry stuff. Hormones like steroids that are not soluble in blood.
What is the function of hemoglobin? What are its protein and nonprotein moieties called?
Oxygen transport, also aids in the transport of carbon dioxide and buffers the pH of blood
Nonprotein- Heme group
What does hemopoiesis mean? After birth, what one cell type is the starting point for all
hemopoiesis? the production of blood cells and platelets, which occurs in the bone
marrow. Hemopoietic stem cell (HSC)
Components of plasma Glucose, Antibodies, Fibrinogen, Hormones, Chloride
Formed elements Platelets, Neutrophils, Erythrocytes, Leukocytes, Monocytes
,Identify at least two each of the transport, protective, and regulatory functions of the circulatory
system. -TRANSPORT: O2, CO2, nutrients, waste, hormones, stem cells
-PROTECTIVE: WBCs, inflammation, antibodies, platelets
-REGULATORY: stabilize fluid distribution, balance pH of ECF, body temp
In the breakdown of hemoglobin, the globin chains __________. are broken down by
macrophages into amino acids
What are the two principal functions of erythrocytes? To pick up oxygen from the lungs
and deliver it to tissues and to pick up carbon dioxide from the tissues and unload it in the lungs
Neutrophils abundance in blood 60-70%
Monocytes abundance in blood 3%-8%
, Lymphocytes abundance in blood 25%-33%
Basophils abundance in blood <0.5%
Eosinophils abundance in blood 2%-4%
Choose the accurate statement(s) about the two reaction pathways that lead to the common
pathway of coagulation. Check all that apply.
1. The intrinsic mechanism uses only clotting factors found in the blood itself.
2. The extrinsic mechanism uses only clotting factors found in the blood itself.
3. The intrinsic mechanism is initiated by clotting factors released by the damaged blood vessel
and perivascular tissues.
4. In most cases of bleeding, both the extrinsic and intrinsic mechanisms work simultaneously to
contribute to hemostasis.
5. The extrinsic mechanism is initiated by clotting factors released by the damaged blood vessel
and perivascular tissues. 1, 4, 5
The cascade of enzymatic reactions in coagulation acts as an ____________ mechanism to
ensure rapid clotting of blood. amplifying
