Answer:
The immune response of the human body to infections brought on by invading agents, whichever these may be, can be classified into two: the innate response and the adaptive response. While the first one is totally unprogrammed, and will be activated massively once the proper exposure to the pathogen hsa been carried out, the second one is much more coordinated, and it depends entirely on the capacity of the immune system to "remember" a pathogen.
In the adaptive immune response, we also have two categories, the humoral response, which is carried out by the B lymphocytes and their antibodies, and the cellular response, which is the responsibility of T lymphocites. As such, the answers would be:
1. A B lymphocyte is the one responsible, by producing antibodies, of mounting the humoral response to infection.
2. The most common immunological cell that can be found in the bloodstream, and which serves as a phagocyte, are Neutrophils. These cells can be found in the blood at a percentage of 60 to 65%, making them the more numerous of all white blood cells in the blood.
Answer:
The correct answer is: (a) Â B lymphocyte; (b) neutrophil
Explanation:
(a) Lymphocyte is a type of leukocyte in the immune system of vertebrates.
The B lymphocytes are the lymphocytes which are responsible for the secretion of the antibodies and are a part of the humoral immunity component of adaptive immune system of the vertebrates.
(b) Neutrocytes, also called the neutrophils, are the phagocytes and the most common type granulocytes, and white blood cells, which are an important part of innate immune system.
