a
4
Which of the following statements explain why red blood cells are specialized for oxygen transport?

(1) Red blood cells contain hemoglobin.

(2) Red blood cells lack a nucleus.

(3) Red blood cells have many mitochondria and thus generate ATP aerobically.

(4) The biconcave shape of RBCs provides a large surface area for the inward and outward diffusion of gas molecules

(5) Red blood cells can carry up to four oxygen molecules for each hemoglobin molecule
1,2,4 and 5
5
Which of the following are true statements?

(1) White blood cells leave the bloodstream by emigration.

(2) Adhesion molecules help white blood cells stick to the endothelium, which aids emigration.

(3) Neutrophils and macrophages are active in phagocytosis.

(4) The attraction of phagocytes to microbes and inflamed tissue is termed chemotaxis.

(5) White blood cells are the most numerous formed elements during disease processes
1,2,3 and 4
6
A person with type A Rh negative blood can receive a transfusion with blood of which of the following types?

(1) A positive,

(2) B negative.

(3) AB negative,

(4) 0 negative,

(5) A negative.
4 and 5
7
The components of blood are_____________ and ____________, which includes ____________,_____________ and___________
plasma and formed elements, wbc, rbc and platelets
8
Plasma minus its clotting proteins is termed______________
serum
9
The stages of blood clotting are as follows:
1.the formation of ______________ by initiation of either the __________ or ___________ pathway or both.
2. the conversion of ________________ into _____________ by action of chemical formed in stage 1.
3. the conversion of ____________ into______________
1. prothrombinase, intrinsic, extrinsic
2. prothrombin, thrombin
3. fibrinogen, fibrin
10
Cell fragments enclosed by a piece of the cell membrane of megakaryocytes and containing clotting factors are called________________
platelets (thrombocytes)
11
True or false
Hemoglobin functions in both oxygen and carbon dioxide transport and blood pressure regulation.
  • true
  • false
12
True or False
Blood groups include the ABO, Rh, Lewis, Kal, Kid, and Duffy systems, among others.
  • true
  • false
13
a tissue protein that leaks into the blood from cells outside blood vessels and initiates the formation of prothrombin activator
thromboplastin
14
an anticoagulant
heparin
15
required for normal blood clotting
vitamin k
16
its formation is initiated by either the extrinsic or intrinsic pathway or both; catalyzes the conversion of prothrombin to thrombin
prothrombinase
17
glycoproteins and glycolipids on the surfaces of red blood cells that can act as antigens
agglutinogens
18
forms the threads of a clot, produced from fibrinogen
fibrin
19
can dissolve a clot by digesting fibrin threads
plasmin
20
serves as the catalyst to form fibrin; formed from prothrombin
thrombin

contain hemoglobin and function in gas transport
red blood cells
22
young neutrophils showing a rod-shaped nucleus
bands
23
white blood cell showing a kidney-shaped nucleus
monocytes
24
monocytes that roam the tissues and gather at sites of infection or inflammation
wandering macrophages
25
occur as B cells, T cells, and natural killer cells
lymphocytes
26
combat the effects of histamine and other mediators of inflammation in allergic reaction; also phagocytize antigen-antibody complexes
eosinophils
27
respond to tissue destruction by bacteria; release lysozyme, strong oxidants, and defensins
neutrophils
28
older neutrophils with several different shaped nuclear lobes
polymorphs
29
monocytes that leave the blood and reside in a particular tissue such as Kupffer cells in the liver
fixed macrophages
30
involved in inflammatory and allergic reactions; are involved in hypersensitivity reactions

33
give rise to red blood cells
myeloid cells
34
give rise to lymphocytes
lymphoid stem cells
35
