BLG 111 Midterm Review Questions With
Correct Answers
Functions of blood - CORRECT ANSWER✔✔-transportation, regulation, protection
| | | | | | |
Components of whole blood - CORRECT ANSWER✔✔-plasma, buffy coat,
| | | | | | | | |
erythrocytes (RBCs) |
Erythrocytes - CORRECT ANSWER✔✔-- part of the formed elements
| | | | | | | |
- made up of red blood cells
| | | | | |
- living matrix
| |
- most dense so its at the bottom when blood is spun
| | | | | | | | | | |
- disc shape and bendy
| | | | |
- anucleate so more Hb can fit
| | | | | | |
- no organelles other than cytoplasm which is filled with Hb
| | | | | | | | | |
- produced in red bone marrow from stem cells
| | | | | | | |
Buffy coat - CORRECT ANSWER✔✔-part of the formed elements, living matrix,
| | | | | | | | | | |
contains WBCs and platelets
| | |
Plasma - CORRECT ANSWER✔✔-non-living matrix, least dense (at the top), 90%
| | | | | | | | | | |
water, contains plasma proteins, electrolytes, nutrients and gasses
| | | | | | |
,Plasma proteins - CORRECT ANSWER✔✔-1. albumin (osmotic pressure, binds
| | | | | | | | |
H2O and helps blood retain water, transport molecule for nutrients and drugs)
| | | | | | | | | | |
2. globulins (antibodies and transport proteins)
| | | | |
3. fibrinogens (functions in blood clotting)
| | | | |
Hemoglobin - CORRECT ANSWER✔✔-- heme = red pigment | | | | | | |
- globin = protein, has 4 polypeptide chains, 2 alpha and 2 beta
| | | | | | | | | | | | |
- 4 heme groups total
| | | |
Hematopoiesis - CORRECT ANSWER✔✔-- forming of RBCs, WBCs, and platelets
| | | | | | | | |
- happens in red bone marrow via stem cells
| | | | | | | |
red bone marrow - CORRECT ANSWER✔✔-- in proximal heads of femur and
| | | | | | | | | | | |
humerus bones |
- in newborns, spongy bone contains it
| | | | | |
Ferritin - CORRECT ANSWER✔✔-storage protein that stores iron and releases it
| | | | | | | | | | |
when needed |
Transferrin - CORRECT ANSWER✔✔-transfer protein which iron binds to
| | | | | | | |
Erythropoiesis - CORRECT ANSWER✔✔-- type of hematopoiesis | | | | | | |
- productions of just RBCs
| | | |
- feedback loop
| |
, 1. Stimulus | |
2. Kidney will release erythropoietin
| | | | |
3. EPO stimulates red bone marrow
| | | | |
4. More RBC production
| | |
5. More RBC = more O2 carrying ability
| | | | | | |
Hemodilution - CORRECT ANSWER✔✔-Less RBCs because there is more blood (ie;
| | | | | | | | | |
pregnant people)
| |
Anemia - CORRECT ANSWER✔✔-can be caused by:
| | | | | |
1. too much blood loss
| | | |
2. not enough RBCs produced
| | | |
3. too many destroyed RBCs
| | | |
Hemorrhagic anemia - CORRECT ANSWER✔✔-- too much blood loss usually from
| | | | | | | | | | |
a severe wound
| |
- treated by giving whole blood
| | | | | |
- chronic hemorrhagic anemia is slight but persistent blood loss
| | | | | | | | |
iron deficiency anemia - CORRECT ANSWER✔✔-- low iron intake
| | | | | | | |
- RBCs are small and pale and cannot make enough Hb
| | | | | | | | | | |
- treatment is iron supplements
| | | |
