Week 8 - Blood Worksheet Flashcards
3 Locations where blood can be found
- Arteries
- Veins
- Capillaries
Describe Blood
- Connective Tissue - connects the body systems together
- Delivers Oxygen and nutrients
- Removal of waste
- Transports hormones
- Regulation of Temperature and pH
- Protection (WBCs & Platelets)

Describe plasma
90% water & contains:
1. nitrogenous waste
2. nutrients
3. electrolytes
4. hormones
5. respiratory gases
immune function
Produced in the liver
1. Albumin
2. Globulins
3. Fibrinogen
Albumin is important for
Osmotic balance
60%
Fibrinogen is important for
Blood clotting
4%
Glubulins are important for
immunity
36%
Alpha Beta important for
transports proteins
Gamma important for
Antibodies
What are the Non-protein nitrogenous substances
- lactic acid
- urea
- creatinine
Organic chemicals absorbed from the digestive tract
Lipids
Proteins
CHO
Respiratory gases
Oxygen
Carbon dioxide
Which biological molecules and minerals are necessary for RBC production and what aspect of cell production are they needed for?
Iron and B12
Erythposeisis - production of RBCs in bone marrow
Erythropoietic factor protein - converts to plasma proteins - Erythropetin and goes tp the bone marrow to produce RBCs.
Give two examples of nutritional anemia
- Pernicious - B12
- Iron deficiency
How does the number of RBCs affect the viscosity of blood?
more RBCs the thicker it becomes
Higher viscosity
What percent of WBCs have hemoglobin?
0% - WBCs do NOT have hemoglobin
RBCs have hemoglobin
What would a RETICULOCYTE COUNT indicate if not within normal values?
Test to determine if RBCs are being created in the bone marrow at an appropriate rate
Which white blood cells are elevated in infectious mononucleosis
Lymphocytes
How are the various types of leukemias named?
By the number of WBCs
Low WBCs = Leukopenia
High WBCs = Leukocytosis
What are the most common causes of death for patients with leukemia?
- Death due to secondary infection
- Low platelet production resulting in hemorrhaging
What could result in anemia during pregnancy?
dietary - iron
Folate deficiency anemia - due to increased Blood Volume
Which type of WBC is elevated during parasitic infections?
Basophils
