The buffy coat evidenced by separating blood cells is comprised of ___...
The buffy coat is a layer of white blood cells and platelets that can be seen after separating blood cells through centrifugation. It is located between the plasma (the liquid component of blood) and the red blood cell layer. The correct answer is option 'D', which states that the buffy coat is comprised of platelets and leukocytes (white blood cells).
Explanation:
1. Buffy coat:
- The buffy coat is a thin layer that appears as a whitish or yellowish band in a centrifuged blood sample.
- It is formed when the blood is spun at high speeds in a centrifuge, causing the components to separate based on their density.
- The buffy coat is located between the plasma and the red blood cell layer.
2. Platelets:
- Platelets, also known as thrombocytes, are small, irregularly shaped cell fragments that are essential for blood clotting.
- They are produced in the bone marrow and play a crucial role in hemostasis, preventing excessive bleeding.
- Platelets are involved in the formation of blood clots by aggregating at the site of injury and releasing clotting factors.
3. Leukocytes:
- Leukocytes, commonly known as white blood cells, are a diverse group of cells that play a vital role in the immune system.
- They are responsible for defending the body against infectious agents, such as bacteria, viruses, and fungi.
- There are several types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific functions in the immune response.
4. Composition of the buffy coat:
- The buffy coat is primarily composed of platelets and leukocytes.
- Platelets are present in the buffy coat due to their relatively high density compared to the red blood cells and plasma.
- Leukocytes are also present in the buffy coat because they are larger and have a higher density than red blood cells.
- The buffy coat contains a mixture of different types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
In summary, the buffy coat is a layer of platelets and leukocytes that can be observed after separating blood cells through centrifugation. It plays a crucial role in blood clotting and immune defense.
