Cardiovascular System: Blood
Cardiovascular System: Blood
Laszlo Vass, Ed.D. Version 42-0007-00-01
Purpose
Explain why you did this lab and what if any safety precautions needed to be followed.
For this lab I had to prick my finger, then with the bleach solution I had to dab it and then carefully drop the blood on the slide. Once I was finished I had to take the second slide and smear the blood. I had to let the slide dry. Then I had to prick my finger again and make 3 more slides. Then I had to mix the chemical with a toothpick and then look under with the microscope.
Because I had to prick my finger I had to make sure the pin was cleaned with alcohol and burned, then I rubbed an alcohol swab on my finger. I made sure the slides were also clean. I didn’t allow anyone to touch my slides, and I soaked them in bleach before cleaning them.
Exercise 1: Observing Your Own Blood
Observations
Sketch and describe what you saw on the prepared slide of human blood:
I really couldn’t see much of anything on my prepared slide of human blood, it was just full of a bunch of pink dots/cells which were also not very vivid.
Sketch and describe what you saw on the blood smear slide using your own blood:
Much like the first this blood had a bunch of dots and blobs I couldn’t recognize. However this one was much more vivid and I could see the outline of the cells.
Questions
What are the components of blood?
Blood has several components, it is made of red blood cells, white blood cells, platelets and plasma.
What is the function of red blood cells?
Red blood cells carry oxygen and hemoglobin throughout the body, which helps the body preform homeostasis.
List the five types of leukocytes and describe the function of each.
Neutrophils- These leukocytes find bacteria/infection in the body and kill it.
Monocytes- These leukocytes defend the immune system, help
