Difficulties defining the terms Health and Disease
Disease - It is usually defined as any condition that adversely affects the normal functioning of the body. It will involve reduced health within a person.

This could be due to the effect of a pathogen, a non infectious means, or your genes.

Disease may involve a wide range of conditions, from a bee sting to more significant diseases, eg. malaria

If you follow the definition precisely a broken arm or pregnancy would be considered a disease
Normal functioning can also change with age etc

How your health is maintained:
Outcome 1.2 Outline how the function of genes, mitosis, cell differentiation and specialisation assist in the maintenance of good health
Genes contain coded information for proteins that repair, control and manufacture tissue components.
When a gene is allowed to be expressed (gene expression) it can produce specific arrangements of amino acids, polypeptides, and ultimately, proteins, such as enzymes which permit correct bodily metabolism. If a gene is not allowed to function correctly it can affect an organism and reduce its health therefore leading to disease. Gene functioning is essential for good health. A faulty gene can lead to disease because it will affect the functioning of the organism.
If you have a problem with your genes eg Cystic Fibrosis you will be more likely to succumb to respiratory diseases.




Difficulties defining the terms Health and Disease
WHO's definition:
Health is described as a state of complete physical (biology), mental and social well-being not just being free of disease or infirmity

Good health typically involves the complete functioning of the body and not just freedom from disease. Generally, good health will include being active and happy, being free from pain, getting along with others and being free from stress.

Problems: Health will have very broad meanings. Health is very subjective - what is good health to some people may be different to others. Some people with a disability or chronic disease may considered themselves healthy as they have learnt to adapt.
Health as used in normal conversation may be different to the scientific meaning of health.
Health constantly changes - varies on a daily basis and is not just the absence of disease. Health varies with age and the susceptibility to disease. Could be very hard to achieve being healthy to cover all three aspects in any given day.


Outcome 1.2 Outline how the function of genes, mitosis, cell differentiation and specialisation assist in the maintenance of good health
Differentiation: cells mature and take on different structural features, so that they become structurally suited to perform a specific function in the body.
Specialisation: specific genes are ‘switched on’ in order to perform a particular function in the body.
Differentiation and specialisation enable cells to work together in a healthy body to carry out complex functions in a controlled and co-ordinated way in order to maintain and repair tissues.
If differentiation and specialisation of cells do not occur for any reason, the cells would not be able to function effectively and processes in the body would not be co-ordinated. eg immune response


Outcome 1.2 Outline how the function of genes, mitosis, cell differentiation and specialisation assist in the maintenance of good health
Every day millions of cells die and must be replaced. Mitosis produces identical cells and is a critical part of the cell cycle by maintaining and repairing cells and tissues.

Cells are the basic functioning unit of the organism, and the production of identical cells is therefore vital for good health

If cells are damaged through injury and disease they need to be replaced by healthy cells near the site.

There are genes that are responsible for DNA repair, protein synthesis for the cell growth and mitosis and tumour supressing
