Question

All selected options are wrong

Which of the following about Neutrophils is TRUE? Neutrophils are white blood cells that are commonly that are responsible for the phagocytosis of foreign material. Neutrophils are white blood cells that transport oxygen and carbon dioxide. Neutrophils are lymphocytes. Neutrophils are primarily responsible for the destruction of parasites. Neutrophils are red blood cells that are commonly found circulating in the circulatory system.

Answer 1

1. Answer: Neutroplils are white blood cells that are comonly responsible for the phagocytosis of foreign material. - True

Neutrophils are a type of white blood cell (WBC or granulocyte) that protect us from infections, among other functions. Neutrophils can secrete products that stimulate monocytes and macrophages. Neutrophil secretions increase phagocytosis and the formation of reactive oxygen compounds involved in intracellular killing. Secretions from the primary granules of neutrophils stimulate the phagocytosis of IgG-antibody-coated bacteria.

2. Epidermis is a part of lines of defense against infectious agents. - true

Physical and chemical barriers form the first line of defense when the body is invaded. The skin has thick layer of dead cells in the epidermis which provides a physical barrier against infectious agents. The mucous membranes produce mucus that trap microbes and the periodic shedding of the epidermis removes microbes.

3. Monocyte true

Neutrophils are the principal cells that engulf and destroy the invading micro-organisms. The influx of neutrophils is followed a short time later by monocytes that rapidly differentiate into macrophages.

4. Urinary tract infections are primarily caused by motile enterics - true

Urinary tract infections (UTI) is primarily an ascending infection caused by organisms, primarily enteric bacteria, residing in the intestinal flora.
