|---|---|---|---|---|---|
| What is pathogen? | Organism that cause diseases
🗑
|
||||
| What is immunity? | The ability to resist infection
🗑
|
||||
| What is general system? | Is non-specific. This means that it acts against all pathogens.
🗑
|
||||
| What is specific defence system? | Is also called the immune system. It attacks particular(or specific) pathogens
🗑
|
||||
| First line of general defence | Skin,Clotting,Lysozyme,Sebaceous Glands, Mucous, Cilia, Acid and Beneficial Bacteria
🗑
|
||||
| S: Physical barriesr | SKIN
🗑
|
||||
| C:The skin is broken, blood ... prevents the entry of further pathogens | CLOTTHING
🗑
|
||||
| L: This is an enzyme found in sweat, tears and saliva. It attacks and dissolves the cell walls of many bacteria | LYSOZYMES
🗑
|
||||
| S.G:Produce chemicals that kill bacteria | SEBACEOUS GLANDS
🗑
|
||||
| C:Theses beat and create current, which moves mucous back up the respiratory system so that it can be swallowed into stomach | CILIA
🗑
|
||||
| A:Hydrochloric... in the stomach kills many pathogens | ACID
🗑
|
||||
| B.B: In the vagina produce lactic acid. This acid prevent the growth of pathogens | BENEFICIAL BACTERIA
🗑
|
||||
| Second line of general defence | Destruction of pathogens by white blood cells, production proteins kill or prevent pathogens from reproducing
🗑
|
||||
| Types second line of general defence | White blood cells
Defence proteins
Inflamation
🗑
|
||||
| White blood cells | Micro-organisms they realease number of chemicals. Destroy any bacteria, viruses or other micro-organisms that they meet
🗑
|
||||
| Types of white blood cells | Phagocytes and magrophages
🗑
|
||||
| Phagocytes | Sunrround and ingest pathogens
🗑
|
||||
| Magrophages | Phagocytes very large, move around the body in body fluids and act as scavengers for pathogens
🗑
|
||||
| Defence proteins | 20 proteins found in the blood plasma. The proteins in complement are activated by infection, and they destroy viruses and other pathogens. Multiplication and help to limit
🗑
|
||||
| Specific defence system | Attacks particular(or specific) pathogens
🗑
|
||||
| Types of specific defence system | Lymphocytes and monocytes
Antigens and antibodies
Active immunity
🗑
|
||||
| Monocytes | Recognise foreign molecules, digest a pathogen, antigens. These antigens then stimulate the production of antibodies
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
