Physical development
The changed that relate to people’s size and shape, and therefore, body structure.
Intellectual development
The ways in which people are able to think and reason.
Emotional development
Deals with feelings and moods and the ways in which people express, understand and exercise control over them.
Social development
The increasing complexity of behaviour patterns used in relationships with other people.
Menstruation
Menstruation is the process in a women when blood and other material from the lining of the uterus is discharged once a month from puberty until menopause.
Stage 1 (Menstrual phase)
it is the elimination of the lining of the uterus from the body through the vagina. Menstrual fluid contains blood, cells from the uterus and mucus. It is often call a period and it occurs between three days and one week.
Stage 2 (Follicular phase)
It occurs on the first day of menstruation and it ends with ovulation. The pituitary gland secretes follicle stimulating hormone (FSH) which stimulated the ovary to produce around five to 20 follicles. Each follicle is a immature egg and it will develop to become mature.
Stage 3 (Ovulation)
it is the release of the mature egg from the surface of the ovary. The egg travels down the fallopian tube to the uterus where it may get fertilised or it will die.
Stage 4 (Luteal phase)
During ovulation, the egg bursts from its follicle. If the egg is fertilised, it will implant into the lining of the uterus to form the corpus luteum. If pregnancy does not occur the corpus luteum will die.

Protein
- Macromolecule
-
Protein
- Macronutrient
- Forms amino acids which are ‘building blocks’ and are used in growth and repair for healthy body.
- Secondary source of fuel for energy production.
Eg. meat, milk, chicken,
fish, pork.
- Secondary source of fuel for energy production.
- Forms amino acids which are ‘building blocks’ and are used in growth and repair for healthy body.
Lipids/ fats
- Macronutrient
1. Main function is to provide fuel for energy production
2. Provides cushioning (& protection) for vital organs
3. Assists in temperature control
4. Excess fats are stored as adipose tissue in the body
e. g Olive oil, avocado, canola oil, nuts, fried foods.
Carbohydrates
- Macronutrient
1. Is a source of fuel for energy production to healthy body function
2. Is stored as fat if not used for energy production and can therefore contribute to obesity.
e. g Cereals, rice, pasta, simple sugars
