Hello. It is not possible to make a report of your class in the laboratory, without having attended that class. For this reason, I will show you how this report can be written. I hope it helps you.
You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.
In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.
Finally, you should end the report with a conclusion, showing what you have learned from this experience.

When blood is drawn from a blood vessel in your arm, it is dark red. This color indicates that the blood was taken from the vein.
Why was my blood so dark when drawn?
Hemoglobin, a protein found in blood cells that enables the delivery of oxygen throughout the body, contains iron, which gives human blood its red color. However, the amount of oxygen in the blood affects the hue. Blood that contains a lot of oxygen will appear bright red. If blood is drawn from an artery that transports blood from the lungs to the rest of the body, this is typical.
Deoxygenated blood is contained in the veins, which carry blood back to the lungs from the body. Based on the light wavelengths they reflect, chemicals appear to our eyes in specific colors. As blue-green light is absorbed by hemoglobin attached to oxygen, red-orange light is reflected into our eyes, giving the appearance of redness. Because of this, when oxygen attaches to iron in the blood, the color turns brilliant cherry red. Blood is a deeper shade of red when it is not coupled to oxygen.
