Total questions: 30
Worksheet time: 16mins
Which of the following is considered as the first line of defence of the human body?
Inflammation reaction
Secretion of mucus in the respiratory system
Macrophages decompose bacteria through phagocytosis
Secretion of histamine
During inflammation, the blood capillaries become more permeable due to the existence of
Monocytes
Leucocytes
Histamine
Lysozyme
One of the PHYSICAL shields of the first line of defence of the human body is
Secretion of sebum of the skin
Hydrochloric acid in the stomach destroys bacteria
Lysozyme present in nasal mucus and saliva
Continuous shedding of dead cell layers on the skin surface
Antibodies are produced by
All cells are possible to produce antibodies
Phagocytes
Histamine
Lymphocytes
The process by which microorganisms or other particles (eg dead cells) are trapped and digested by phagocytes is _____________
Phagocytosis
Inflammation
Immune response
Agglutination
The lymphocytes are formed in
Inflamed areas
Lymph nodes
Lysosomes
Any tissues
How does fever help to fight against diseases?
Raises the temperature of the human body to directly kill bacteria
Raises the temperature of the human body to denature the protein of bacteria
Increases phagocytic activity
Increases heart rate
The T lymphocyte cells attack ________
Antigens
The pathogen
Antibodies
Cells infected by pathogens
The combination of microorganisms, fragments of tissues and white blood cells is called
Phagocytes
Lymphocytes
Pus
Phagosome
Inflammatory response occurs in infected areas. These areas become red because
Histamine increases the permeability of blood capillaries
Platelets accumulate in the infected areas
Phagocytes carry out phagocytosis
Histamine causes the blood capillaries to expand and increases blood flow
The secondary immune response occurs because of the existence of _________ during primary immune response
Memory cells
Killer T cells
Histamine
Macrophages
Which of the following is only present during specific immune response?
Antigens
Antibodies
Antinodes
Antidadah
"Antibodies coagulate the pathogens and make them an easy target to be trapped and destroyed by phagocytes"
This describes __________
Neutralisation
Opsonisation
Agglutination
Precipitation
When antibodies bind with toxins produced by bacteria and neutralises the toxin, it is considered as
First line of defence
Second line of defence
Third line of defence
An insoluble complex is formed when antibodies react with dissolved antigens. This process is known as
Agglutination
Lysis
Opsonisation
Precipitation
Antibodies that combine with antigens and act as a marker for phagocytes to recognise the antigens and destroy them are known as
Lysine antibodies
Opsonin antibodies
Any types of antibodies
Antigens
When antibodies combine with antigens and cause bacteria to be broken down and decomposed, this process is known as _________, and it requires __________________
Opsonisation, opsonin antibodies
Neutralisation, toxin
Lysis, lysine antibodies
Precipitation, phagocytes
Which of the following describes the situation when antibodies are obtained from an external source?
Injects Sinovac vaccine
A person is permanently immuned against chicken pox
Antiserum injection
Injection of tetanus 破伤风 vaccine
Antibodies are produced naturally by lymphocytes in human bodies in which case?
Antiserum injection
Vaccine injection
Breastfeeding
Inflammation
A suspension of pathogens that are weakened, dead or non-virulent is

Antiserum
Colostrum
Placenta
Rabies 疯狗症
Injection of anti-rabies antiserum is considered as
Natural active immunity

Antiserum
Antibodies
Antigens
The purpose of this kind of immunity is
Prevention
Treatment
When immediate protection is required
Inflammation
Antiserum is a serum that contains
Specific antigens
Specific antibodies
Non-specific antigens
Non-specific antibodies
HIV causes AIDS, which is a disease that destroys the immune system of the human body. HIV is NOT transferred to a baby through
Pregnancy
Birth
Breastfeeding
Skin contact with a baby
HIV is transmitted through?
(more than one answer)
