Answer 1

1. Acquired immunity that a fetus obtains from maternal antibodies that cross the placenta is called: Naturally acquired passive immunity where a baby's immunity against infections is obtained by antibodies through breast milk from Mother Artificially acquired natural immunity is acquiring immunity through artificial means.Naturally acquired active immunity is a kind of immunity where natural exposure to an infectious agent or other antigen by the body and thereby body responds by making its own antibodies.Artificially acquired active immunity can be obtained through means of vaccine. So option B would be appropriate answer

2. Which of the following cells plays a role in both specific and non-specific defenses?

The answer would be All of the above as it covers all the functions like Filtering, recycling, and producing

   lymph, Collecting surplus fluids, Absorbing fat-soluble molecules from the digestive tract.

3. Which of the following cells plays a role in both specific and non-specific defenses?

Lymphocytes are the cells which plays both the role in specific and non specific defenses where neutrophils and

monocytes are non specific type

4. Small proteins that are secreted by virally infected cells that protect neighboring cells and thwart further multiplication

of viruses are Interferon

5. Answer is all of the above as Phagocytic cells include neutrophils, eosinophils, monocytes, macrophages, dendritic cells, and B-lymphocytes

6.Phagocytosis refers to which immune system response - Engulfment of molecular materials as Phagocytosis is a  process by which certain living cells called phagocytes ingest/engulf other cells or particles

7.Which of the following is NOT true regarding lymphatic capillaries?

Lymphatic capillaries are less porous than blood capillaries as Lymph capillaries are able to absorb larger particles from the tissues, such as proteins, cells, bacteria and other large substances, which cannot be absorbed by blood capillaries.

8. Lymph flows: Into the capillaries.

9.Which of the following is NOT an organ of the immune system - Esophagus

10.What is the purpose of a cytokine? Recruit immune cells.

11.The lining of the gastrointestinal tract are an example of what type of immune system defense is

Pre-Determined which is innate in nature

12.Where are immune cells synthesized - The bone marrow.

13.What are the proteins released by leukocytes to recruit other immune cells and regulate the immune response? Cytokines

14.Specialized lymphatic capillaries that project into the small intestines are called: Lacteals

15. Which of the following is not a splenic function - Monitor Blood Flow
