What is the term for blood development?
✓✓ hemopoiesis
Where do blood cells form after birth?
✓✓ Red bone marrow
What percentage of the blood is plasma vs. formed elements (know what
formed elements are?)
✓✓ Plasma: 55%
Formed elements: 45%
What substances are found in the plasma of the blood?
✓✓ 91.5% water, 7% proteins, and 1.5% solutes (other proteins)
(plasma is produced in the liver)
What are the plasma proteins and what are they responsible for?
✓✓ The major proteins found in plasma include:
- Albumin (60%)- regulate the osmarlity of the blood
- Globulins (30-38%)- immunoglobulins and transporting lipids/fat soluble
vitamins
- Fibrinagen (4-7%)- blood clots by forming fibrin

differ in terms of life cycle?

Expert solutions
✓✓ Erythrocytes (RBC)
-Go through a recycling process ¨ 100-300 days (agranular)
- 120 days ¨ Some B & T cells exist for years
- Must replenish at a rate of 2 ¨ 12 hrs. to 3 days (granular)
million per second
- Broken down in spleen and liver
Leukocytes (WBC)
- 100-300 days (AGRANULAR)
-Some B & T cells exist for years
-12 hrs. to 3 days (GRANULAR)
Which are the granular/agranular leukocytes and what are their general
functions?
✓✓ GRANULAR (end with PHIL -- Grandpa Phil)
-Neutrophils: 1st to respond to bacterial invasion
-Eosinphils:replace enzymes that combat inflammation in allergic reactions
-Basophils: intensify inflammation
AGRANULAR (end in OCYTES)
-Lymphocytes: immune cells such as B & T cells
-Monocytes: become macrophages, clean up debris post infection
Reaction (ex: heparin, histamine)
What is erythropoiesis
✓✓ Erythropoiesis: Cycling and recycling production of red blood cells
What hormone regulates it and where do each of the components go during
the recycling process?
✓✓ -Erythropoientin: Hormone that triggers erythropoiesis
-Transferred to the bone marrow and recycled back into hemoglobin
What are the "raw ingredients" needed to continue the life cycle?
✓✓ ¨ Raw ingredients needed include: Iron, vitamin B12, globin, and EPO
What are the 8 different blood types?
✓✓ A+, A-, B+, B-, AB+, AB-, O+, O-
