WHAT IS IN BLOOD?

Blood is a connective tissue.
Transports all the elements required by our cells.
Contains components that protect the body from infection and clears metabolic wastes from tissues and organs.
Suspended in a water-based, somewhat yellow fluid known as plasma.

When the formed elements and clotting factors are removed from plasma, a serum is left behind that contains minerals, nutrients, wastes, and antibodies from the immune system.

White blood cells (WBC)
Red blood cells (RBC)
Platelets

THE ROLE OF BLOOD

Materials transported by blood? Nutrients Oxygen Carbon dioxide Wastes
How does it protect the body? Fights diseases with white blood cells
How does it stop bleeding? Platelets clot the blood and help weave a net across a cut or injury

PLASMA OF BLOOD

What is it made of? Plasma consists mainly of water (55%). A variety of other substances are dissolved in it, salts, nutrients, proteins, glucose, oxygen, wastes

RED BLOOD CELLS (RBCs)

What component of red blood cells carries oxygen and makes the RBCs red in color? hemoglobin is a compound in red blood cells that's responsible for giving blood its red color
Red blood cells are also called… erythrocytes
What do RBCs transport in the body? oxygen from the lungs to other cells in the body carbon dioxide, a waste gas, back to the lungs where it can be exhaled
What do RBCs have on their surfaces? two possible carbohydrates which coat their surface. The letters "A" and "B" refer to these two different types of carbohydrates. blood type A has the type of A carbohydrate in their blood cells, blood type B has the B-type carbohydrate in their blood cells. AB blood has both carbohydrates, type O blood has neither of these carbohydrates.

WHITE BLOOD CELLS (WBC'S)

White blood cells are also called… Leukocytes
What do WBCs do? help the human body fight diseases
Can they move into tissues? There are a number of different kinds of white blood cells with various functions. White blood cells are much larger and less numerous than red blood cells. White blood cells have the ability to move through blood vessels into body tissues to fight infections.

PLATELETS

What are they made of? consist of cell fragments that play a key role in blood clotting
What can platelets do? platelets help weave a net across a cut or injury. Without clotting, you'd bleed to death.

ASSIGNMENT DIRECTIONS

For this assessment,

you will read and analyze a case study on a patient with a blood disorder.

There may be some medical terms or procedures in the case study that you do not know or understand.

Please use reliable internet resources to do whatever research is necessary to define terms and get additional information on diseases and symptoms mentioned in the case study.
However, make sure your answers are in your own words and are supported by specific evidence from the text.

SOME ASSISTANCE WITH THE GRADING CHECKLIST

What does it mean that Nikoleta is in the 10th percentile for both length and weight? Is that a desirable statistic if she was in the 50th percentile at birth? (4 points)

If you are not sure what it means to change percentiles, read more here

What are the symptoms of anemia? (4 points)

Refer to the case study and the symptoms experienced by Nikoleta

Why did the parents change Nikoleta’s formula to a high-iron baby formula? (2 points)

Refer to the case study and the explanation provided by Nikoleta’s parents

What components should be in a normal blood sample? What is the function of each of these components? (Refer to page one of the lesson.) (5 points)

Use your worksheet you completed on page 3 of the module

Are the lab results of the blood sample normal? Which values are normal and which are not? (Refer to the chart of Nikoleta’s results.) (4 points)

Use quantitative (numbers and units) values in the data table from the information gathered from the lab to support your answer

SOME ASSISTANCE WITH THE GRADING CHECKLIST

Why was an analysis of Mr. and Mrs. Stamos’s blood ordered? (4 points)

Refer to the case study and the information provided by the doctor

Would a picture of Mr. Stamos’s red blood cells look like Nikoleta’s red blood cells? Why? (2 points)

Use qualitative data and refer to the information provided in the images and descriptions from the case study to support your answer

What is erythroblastic anemia? (4 points)

Complete research outside of the LMS, be sure to cite your resources

What are the general features of Cooley’s anemia? (5 points)

Complete research outside of the LMS, be sure to cite your resources
Be sure to include cause(s), symptoms, possible treatments

What is the structure of hemoglobin and how is oxygen bound to it? (2 points)

There may be some medical terms or procedures in the case study that you do not know or understand.
Please use reliable internet resources to do whatever research is necessary to define terms and get additional information on diseases and symptoms mentioned in the case study.
However, make sure your answers are in your own words and are supported by specific evidence from the text.

Mr. and Mrs. Stamos want to know if it is likely that they would have another child born with erythroblastic anemia. If you were the genetic counselor, what would you suggest to Mr. and Mrs. Stamos concerning having more children? Why? (4 points)

Make sure you support your answer with scientific evidence and not just your opinion
Use a Punnett Square (you can search online easily for the genetics of Cooley’s Anemia, Beta Thalassemia) to support your answer
Keep in mind: a genetic counselor advises and counsels and does not tell a family what to do
