A-Level Biology Lesson "Lung Disease" Summary.

After watching this revision notes video you'll find these useful too (since of course exam questions are typically asked in context), and with a topic like TB typically the questions revolve around: -

 

Prokaryote Structure. and Binary Fission.

 

Phagocytosis. and Antibody Structure.

 

Measuring Lung Function.

 

HIV Structure and HIV replication

Check Your Spec!

★ AQA 3. Students should be able to: interpret information relating to the effects of lung disease on gas exchange and/or ventilation. (TB, Asthma, Fibrosis and Emphysema).

 

★ CIE 10.1 Infectious diseases. b) state the name and type of causative organism (pathogen) of each of tuberculosis (TB). c) explain how, TB is transmitted.

 

★ Edexcel (Biology A – Salters-Nuffield) 6.6 Understand how Mycobacterium tuberculosis (TB) and Human Immunodeficiency Virus (HIV) infect human cells, causing a sequence of symptoms that may result in death.

 

★ Edexcel (Biology B) 6.2 Bacteria as pathogens: ii Understand that pathogenic effects can be produced by invasion of host tissue (Mycobacterium tuberculosis).

 

★ OCR (Biology A) 4.1.1 Communicable diseases, disease prevention and the immune system. (a) bacteria – tuberculosis (TB). (b) the means of transmission (TB).

 

★ OCR (Biology B) 3.2 Pathogens, immunity and disease control: 3.2.1 Pathogenic microorganisms. (a) how pathogens, e.g. bacteria - cause communicable disease. (b) the causes, means of transmission, symptoms and the principal treatment of tuberculosis (TB) To include droplet infection, details of primary and secondary TB and also opportunistic infections (HIV, AIDS).

 

★ WJEC Specification Reference: - IMMUNOLOGY AND DISEASE - (c) the following diseases in terms of: the types of organisms; source of infection; tissue affected; mode of transmission; prevention; control methods and treatment, - tuberculosis.
