Pre-Lab Questions-answer in the space provided
1. Describe the function of 5 types of leukocytes in the blood.
Neutrophils extinguish and digest bacteria or anything toxic from the
environment that could cause harm. Neutrophils are found at the injury site,
and dead neutrophils look like pus.
Eosinophils are known to protect against foreign invaders, such as parasites
and allergens. They release substances that can fight these invaders.
Basophils are also present during an injury, and they release histamine, which
triggers more blood flow to the site and creates swelling.
Lymphocytes protect your body against cancer, viruses, and bacteria, known
as antigens. The T cells help regulate the immune system. In contrast, the B
cells cling to the antigen and cause plasma cells and antibodies to be
produced while also remembering the prior infectious agent. They can also
distinguish blood types.
Monocytes are phagocytes that also destroy invading microorganisms. They
are the largest leukocytes. They can turn into macrophages where they clear
the tissues they enter of pathogens.
2. What is the function of erythrocytes?
Red blood cells' primary function is to carry and transport oxygen through the
body. Another function they have is taking the carbon dioxide out of our
system to the lungs so we can exhale it.
3. Describe the role of platelets in the blood.
Platelets, also known as thrombocytes, are responsible for blood clot
formation. When an injury occurs, platelets stick to the injury, forming a plug.
Then, they work with other coagulating factors in the blood to create a stable
blood clot as part of the hemostasis process.
4. Describe what you would look for to differentiate an artery from a vein in cross-
section when taken from the same body part.
Arteries have thicker walls and smooth muscle cells, so I would look for a well-
developed tunica media. I would also look for a round circular lumen in a cross-
section for arteries, while veins have an irregularly shaped collapsed lumen.
Arteries have more elastic fibers than veins in a cross-section as well. Veins
have valves, while arteries generally do not. Another visual would be the blood
color; while arteries have a brighter red color, veins hold a darker hue.

Activity 1 Copper Sulfate Test

Data Table 1 Time Location in tube Start of the experiment Once the blood hit the solution, it sat in the top of the solution for a couple of seconds. 15 seconds After a couple of seconds, the blood dropped to the bottom of the container. By 15 seconds, it was sitting at the bottom with a slight erection. 60 seconds After 60 seconds, the blood appeared flat on the bottom of the container.

Activity 3 Bleeding Time Test

Arteries have thicker walls, like the first photo above, consisting of three layers. Veins have thinner walls, three layers, and less muscle and connective tissue than the arteries. Veins also have valves, such as the second picture shows. Arteries carry blood to the body through high pressure and do not require valves to prevent backflow. Veins rely on valves to return blood to the heart. One last difference is the color of the blood, as veins will be darker and appear blue through the skin due to deoxygenated blood.

  1. Explain the differences between the aorta and the vena cava. The aorta is the main artery and distributes oxygenated blood from the heart to the body with high pressure. The vena cava has two features: the superior and inferior vena cava. Both bring deoxygenated blood from the body back to the heart with lower pressure.
