a) Phagocytes
b) Antibodies
c) T-Lymphocytes
d) B-Lymphocytes

Answer 1

Answer:

innate immunity is provided by phagocytosis

Explanation:

innate immunity is the first line of defence response of our body.it is activated when a foreign pathogen first invade in our body it is greeted by toll like receptor that contain carbohydrate residue in its surface.This interraction further strikes an alarm to release various immune response regulatoty molecules called cytokines  from t helper cell .The cytokines then receive a signal to propagate themselves to the site of inflamation.After reaching the site of inflamation the cykines along with other immune system cells such as T lymphocyte,macrophages engulf the pathogen and destroy the same by phagocytosis.

Answer 2

Innate immunity is provided by Antibodies.

Option B

Explanation:

• Innate immunity is defined as immunity that is present in a person from birth. This immunity is acquired by the person in form of antibodies that are transported from a mother via the placenta or the mother’s milk.
• Placenta serves as an important barrier to the infection but also transports different antibodies like gamma globulin to the baby. These serve as the innate immunity to the child.
• The milk secreted by the mother for first few days is called colostrum. It is rich in gamma globulins. This also serves to innate immunity.
