1.
What type of leukocyte is pictured above?
Correct Answer
B. EosinopHil
Explanation
The correct answer is Eosinophil. Eosinophils are a type of leukocyte, or white blood cell, that are involved in the immune response against parasites and allergic reactions. They are characterized by their granules that contain enzymes and proteins involved in killing parasites and modulating inflammation. In the given picture, the cell shown exhibits the characteristic morphology of an eosinophil, with a bilobed nucleus and large granules in the cytoplasm. Therefore, the correct answer is Eosinophil.
2.
What type of leukocyte is pictured above?
Correct Answer
C. Monocyte
Explanation
A monocyte is a type of white blood cell (leukocyte) that plays a vital role in the body's immune system. Monocytes are part of the innate immune response, which is the body's first line of defense against infections and foreign invaders.
3.
What type of leukocyte is pictured above?
Correct Answer
C. BasopHil
Explanation
The correct answer is Basophil. Basophils are a type of leukocyte, or white blood cell, that are responsible for triggering allergic reactions and releasing histamine. They are characterized by their dark-staining granules in the cytoplasm, which can be seen in the picture. Eosinophils, monocytes, and neutrophils are also types of leukocytes, but they have different characteristics and functions.
4.
What type of leukocyte is pictured above?
Correct Answer
D. LympHocyte
Explanation
The given image shows a lymphocyte. Lymphocytes are a type of leukocyte, or white blood cell, that play a crucial role in the immune system. They are responsible for recognizing and destroying foreign substances in the body, such as viruses or bacteria. Lymphocytes are characterized by their round shape and large nucleus, which can be seen in the image.
5.
What type of leukocyte is pictured above?
Correct Answer
B. LympHocyte
Explanation
The picture shows a lymphocyte. Lymphocytes are a type of leukocyte, or white blood cell, that play a crucial role in the immune system. They are responsible for recognizing and attacking foreign substances, such as bacteria or viruses, in the body. Lymphocytes are characterized by their large, round nucleus and small amount of cytoplasm. They are an essential component of the body's defense against infections and diseases.
6.
What type of leukocyte is pictured above?
Correct Answer
C. NeutropHil
Explanation
A neutrophil is a type of white blood cell, specifically a type of granulocyte, that plays a crucial role in the body's immune system. Neutrophils are a primary component of the innate immune system, which is the first line of defense against infections.
7.
What is the Leukocyte pictured below?
What type of leukocyte is pictured above?
Correct Answer
D. BasopHil
Explanation
This Leukocyte is a basophil. The white blood cell granules stain blue/black and appear to be showing through the Nucleus, giving it a "ghost-like" appearance. Memorization aid: BLUE BOO BASOPHIL.
8.
What type of leukocyte is pictured above?
Correct Answer
C. NeutropHil
Explanation
This Leukocyte is a NEUTROPHIL. Its granules stain light-pink and light-purple. The one pictured a segmented (seg) neutrophil, a.k.a: polymorpho-nuclear leukocyte. Memorization aid: PINK NEUTROPHIL! NOT RED!
9.
What type of leukocyte is pictured above?
Correct Answer
B. LympHocyte
Explanation
This Leukocyte is a LYMPHOCYTE. The lymphocyte has a LARGE nucleus with little cytoplasm. Memorization aid: LARGE NUCLEUS LYMPHOCYTE
10.
Which type of leukocyte is primarily responsible for combating parasitic infections and is also involved in allergic reactions?
Correct Answer
B. EosinopHils
Explanation
Eosinophils are a type of white blood cell that are particularly involved in the body's immune response to parasitic infections and play a significant role in the manifestation of allergic reactions. They are characterized by their large, brightly staining red-orange granules which contain enzymes used to digest parasitic organisms. Unlike neutrophils which primarily target bacteria, or lymphocytes which are involved in adaptive immunity, eosinophils are specifically adept at combating larger parasitic invaders and mediating allergic inflammatory responses. Basophils, while also involved in allergic responses, are more known for their role in releasing histamine and other mediators.
