Name the three types of increased red blood cell destruction

Back 6

Aplastic anemia, thalassemia, and sickle cell anemia

Front 7

Define anemia

Back 7

Condition in which the blood oxygen carrying capacity is too low to support normal metabolism

Front 8

Define acute hemorrhagic anemia

Back 8

Bleeding usually due to a trauma

Front 9

Define chronic hemorrhagic anemia

Back 9

Usually do to slow internal bleeding such as an ulcer, or bleeding hemorrhoidal vessels, or heavy menstrual cycles

Front 10

known as the graveyard for red blood cells

Back 10

Spleen

Front 11

What happens to hemoglobin when it is salvaged from dead erythrocytes?

Back 11

Hemoglobin is broken down into heme , globin, and iron

Front 12

This product of hemoglobin is transported through the blood via its transport protein transferrin , and stored in the liver as hemosiderin or ferritin for later use in new red blood cells?

Back 12

Iron

Front 13

this product of hemoglobin is degraded into bilirubin, transferred to the liver, delivered to the gallbladder, secreted into the intestine, metabolized to urobilinogen and then to stercobilin by bacteria and excreted in feces as a brown pigment

Back 13

Heme

Front 14

This product of hemoglobin is broken down into amino acids circulated to the delivered cells where the amino acid blocks can be used to build new proteins?

Back 14

Globin

Front 15

Where and why is erythropoietin EPO produced

Back 15

In the kidneys, and when and when O2 to delivery decreases (hypoxia)

Front 16

Define reticulocyte

Back 16

Young red blood cell which has just expelled its nucleus

Front 17

When does erythropoiesis begin

Back 17

When the myeloid stem cell transforms into a proerythroblast

Front 18

What is hematopoiesis and where does it occur

Back 18

Blood cell formation and occurs in red bone marrow

Front 19

What is a hematopoietic stem cell (aka hemocytoblast)

Back 19

Precursor of all formed elements

Front 20

What is hemoglobin

Back 20

Main protein which transports respiratory gases. Made of red 4 heme pigment and 4 globin protein chains. Two alpha chains and 2 Beta chains

Hint 20

How many heme pigments? How many globin protein chains?

Front 21

What are the normal hemoglobin values for men and women

Back 21

Men 13 - 18 grams / 100 milliliters. Women 12 - 16 grams/100 milliliters

Hint 21

(Teens) g/100mL

Front 22

____________ contains one iron atom which combined to 1 O2 molecule

Back 22

Heme pigment

Hint 22

Each hemoglobin molecule has four of these which means that each hemoglobin molecule can bind to 4 O2 molecules

Front 23

What is an oxyhemoglobin

Back 23

A fully oxygenated hemoglobin

Front 24

What is deoxyhemoglobin

Back 24

Hemoglobin after delivering oxygen to the cells in a body

Front 25

Name given to hemoglobin when it is carrying carbon dioxide

Back 25

Caraminohemoglobin

Front 26

What does co2 bind to in the blood

Back 26

It binds to amino groups of globin and not heme. Only 20% of the CO2 in the blood is carried by the hemoglobin the rest is dissolved in plasma

Front 27

What are the normal red blood cell counts for women and men

Back 27

Women, 4.2 to 5.4 million per microliter. Men 4.7 - 6.1 million per microliter
