Erythrocyte-ing
100

Identify the cell: defensin proteins, very phagocytic, respiratory burst (granulocyte)

Neutrophil

100

Binds reversibly with oxygen, made up of polypeptide chains and a heme pigment. 

hemoglobin

100

The process of blood clotting is a: positive or negative feedback mechanism?

positive feedback mechansim

100

where does erythropoiesis take place primarily?

red bone marrow

200

Identify the cell: parasites, allergies, asthma (granulocyte) – red staining contains digestive enzymes

Eosinophils

200

The percentage of RBCs in the blood. Slightly higher in males. 

Hematocrit

200

what are the three stages of hemostasis?

1. vasuclar spasm

2. platelet plug formation 

3. coagulation

200

what is the name of the hematopoietic stem cell 

hemocytoblast

300

Identify the cell: contain histamine, vasodilate & recruit WBCs to inflamed sites (granulocyte)

Basophils

300

the process of red blood cell creation

erythropoesis 

300

the third step of hemostasis involves coagulation which has two different pathways. Which one is faster? Intrinsic or extrinsic?

extrinsic 

300

The kidney receiving low O2 levels will trigger what production?

EPO production

400

Identify the cell: mostly in lymph tissue, contains T-cells and B-cells (agranulocytes)

lymphocytes

400

The fast series of reactions for stopping bleeding and blood loss.

hemostasis

400

Platelets stick to what in damaged vessel walls in platelet plug formation?

collagen fibers

400

What is the primary hormone in erythropoesis and what triggers its release?

EPO, kidney receiving low oxygen levels (low O2 levels in the body or low RBC levels)

500

Identify the cell: enter tissues to become macrophages & activate lymphocytes to mount immune response (agranulocyte)

monocytes

500

blood clotting that reinforces the platelet plug with fibrin threads

coagulation 

500

What is the difference between the instrinsic and extrinsic pathways of coagulation? (explain how they're initiated and mention speeds)

Intrinsic: clot factors found in blood, slower because it has to go through several steps, initiated by a rupture in blood vessel endothelium 

Extrinsic: clot factors outside of blood, faster because it bypasses steps, initiated by tissue cell trauma which exposes blood to tissue factor (TF)

500

What organ is primarily responsible involved in the promotion of erythropoesis?

kidneys
