0:00some diseases and disorders that are
0:02associated with the blood would be
0:05anemia which I mentioned before Amia
0:08meaning blood a meaning absent or
0:10without so this would be someone who has
0:13that decreased number of red blood cells
0:17going down you have leukemia leukemia is
0:20something that originates within the
0:22bone marrow and it's when an individual
0:24has an abnormal amount a large abnormal
0:28amount of white blood cells now remember
0:31I said that white blood cells are
0:33leukocytes aren't typically hanging
0:35around unless there's a reason to so an
0:38elevated amount in this case an
0:39extremely large amount could indicate
0:42leukemia or cancer
0:45sickle cell anemia sickle cell anemia is
0:48genetic uh it it is inherited and it
0:52tends to be more on the dominant gene uh
0:55with this remember when we started out
0:58our lesson we looked at the red blood
1:00cells and the shape so we know that red
1:02blood cells are round but they are
1:04slightly concaved in the Middle where
1:06they have a dip uh that dip that's in
1:09the middle of the red blood cell AIDS in
1:11the red blood cell being able to
1:13transport itself throughout the
1:15circulatory system and so with sickle
1:18cell anemia uh what happens is
1:20individuals have what's called a crisis
1:22and when that crisis occurs that cell
1:25that red blood cells it folds and as it
1:30folds or creases it does not have the
1:33ability to transport itself through the
1:35circulatory system and so the cells tend
1:38to pile up one on top of the other
1:40causes blockage within the circulatory
1:43system which leads to extreme pain lack
1:46of oxygen and canned oftentimes if
1:50sickle cell goes untreated could lead to
1:52death
1:53uh for some reason don't know why it is
1:57linked to individuals with darker skin
1:59tones and also more specifically uh
2:02those that are within the
2:03African-American descent
2:05polycystemia Vera uh this is a disease
2:08of the bone marrow again another one
2:11that's going to result in a high number
2:13of cells but here uh it's not white
2:17blood cells it's red blood cells so with
2:20the elevated amount of red blood cells
2:22this will place a patient at risk for
2:25clotting blood is thicker red blood
2:27cells are going to be more compact could
2:30lead to blood clots and then the very
2:33last disease and disorder that we'll
2:35cover today is called Talus isthemia
2:37this is also inherited and this is of
2:40course it's it falls under the umbrella
2:42of anemia
2:44as a defective hemoglobin chain causes
2:46small pale and short-lived rbcs I
2:51remember a red blood cell has the
2:53capability to sustain and restore itself
2:55every 120 days so someone with Talus
2:58ischemia would probably have to have
3:01blood transfusions because their cells
3:04their red blood cells have a shorter
3:06lifespan
