Q

red blood cell production (erythropoiesis)
hormone involved? where released? function? what’s required for this hormone to be released? what cells are involved? RBC lifespan?

A

hormone: erythropoietin (EPO) controls RBC formation rate
-released by kidneys
works on negative feedback system
-low O2 content-> EPO released
vitamin B 12 & iron (Fe) required
hemocytoblasts divide and differentiate
RBC’s lifespan- 120 days (get old -> die)

Q
red blood cell removal/ recycling
# of RBC maintained by? what happens to old/damaged ones?
A
# of RBCs is constant & maintained by negative feedback
old/damaged cells engulfed by macrophages (pac men) in spleen, liver, red bone marrow

Q

hemoglobin (involved in red blood cell removal/ recycling)

A

broken down into heme & globin
-globin reduced to amino acids
-Fe removed from heme & transported to liver
-rest of heme converted to pigement- BILIRUBIN
-becomes part of bile (made in liver, stored in
gallbladder, yellow/green)

Q

White blood cells aka?

A

leukocytes

22
Q

White blood cells (leukocytes)

called? how much in blood volume? how much total in blood? function? mostly located? 2 different classes of WBC?

A
"true cells"
less than 1% of blood volume 
FUNCTION: protect against pathogens, toxins, cancer cells
formed in red bone marrow by hemoblasts
5,000-10,000 mewL of blood
most WBCs in lymphatic organs
two class of white blood cells
-Granulocytes: stainable granules (have grains)
-Agranulocytes: no stainable granules
23
Q

Granulocytes

size? lifespan? shape? kinds (3)?

A
2x size of red blood cells 
granular cytoplasm 
short life span
kinds:
-neutrophils
-eosinophils
-basophils
24
Q

neutrophils

known for being…? amount in WBCs? granules color? nucleus? function & examples?

A

most numerous WBC - 50-70% of WBCs
stained light purple granules
3-6 lobed nucleus
FUNCTION: fight bacterial infections (ex: cut, sore throat)

25
Q

eosinophils

amount in WBCs? nucleus? granules color? function?

A

2-4% of WBC
bi-lobed nucleus
granules redish-orange

no cytoplasmic granules

kinds: (mainly lymphatic system)
- monocytes
- lymphocytes

28
Q

monocytes

amount in WBCs? shape of nucleus? cytoplasm color? become? function?

A
3-8% of WBCs
LARGEST blood cell
kidney-shaped nucleus, blue cytoplasm

lymphocytes

amount in WBCs? shape of nucleus? location and how many? lifespan? types (2)?

A
30% of WBCs
large, round nucleus
trillions in mostly lymphatic tissues (immune system too)
live for many years
types
-T cells
-B cells
