OD •There are 5-6 liters in a grown male

•It is about 8% of your body weight

You will watch a video that introduces you to all the parts that make up blood. Pay attention to all the different components your blood actually has!

Erythrocytes

AKA: Red Blood Cells Donut shaped! (But there’s not a hole

in the middle, it’s just flattened out) Makes up 45% of all blood Main job: transport oxygen from the

lungs to the rest of the body Only last for 4 months, then they are

removed from the body by the liver Contains hemoglobin

Draw an erythrocyte.

Hemoglobin

Protein on the erythrocyte that holds the oxygen molecule› There are 250 million

hemoglobin molecules on EACH erythrocyte…

› Each hemoglobin molecule can carry 4 oxygen molecules… 250 million x 4 = 1 billion

oxygen molecules can be carried by 1 erythrocyte

Fill in the Blank:Red blood cells, also known as erythrocytes, make up 45% of our blood. They can live for about 4 months, and their main job or function is to transport oxygen from the lungs to the rest of the body. To transport this oxygen, erythrocytes have hemoglobin on them. Hemoglobin attracts about 4 oxygen molecules each.

Leukocytes

Makes up 1% of all blood Protects body, fights infection Can leave the blood vessels to hunt down

and destroy infections! Leukocyte levels can be measured to

determine if person is sick If you are sick (fighting infection), your body

makes a lot of leukocytes to win the fight… so more leukocytes = probable infection

AKA: White Blood Cells

Platelets

Makes up 1% of all blood Pieces of cells Clots bleeding

Plasma

Makes up 53% of all blood Fluid part of blood

› Mostly water

Label each of the following in the picture below: Erythrocyte, leukocyte, platelet, plasma

Hematopoiesis

Blood cell formation (making blood cells)

Happens in:› the ends of long bones in red bone marrow› flat bones like skull and pelvis› ribs & sternum

Blood Transfusions

Blood Transfusion – the transfer of blood from one person to another

Why would someone need to receive blood from another person?

Certain diseases like Sickle Cell AnemiaCancer, for example LeukemiaSurgeries like organ transplant or Open-Heart Surgery

Open-Heart surgeries can require up to 10 pints of blood

Blood Types

There are 4 blood types:

A = 40%B = 11%AB = 5%O = 44%

You will watch a video that that gives you the details about why and how we have different blood types. After that, you will have to explain what makes each blood type different.

Remember... The Key to Blood Donation is Blood Types!

1

•Antigens are little proteins on the outside of red blood cells

2

•Antibodies are made for any antigens you don’t have on your red blood cells

3

•If you put blood in your body, and you have already made antibodies for those antigens, your body will start attacking

4

•This attacking can lead to blood clots, which can cause heart attacks and strokes

Open-ended:Explain the following things:1. The types of blood(How many and what are their names?)2. Which types can be donated to which other types and why?

I love creating interactive lessons that educators can use to inspire their students’ learning! I hope you found this lesson helpful in engaging all of your learners.

Thank You!Abby
