Joana,

This wasa very good approach to P1 that covers all the main stages of development.

Well done!

Both male and female reproductive systems need to be functioning effectively for conception to take place naturally. The female sex hormones oestrogens and progesterone are produced by the ovaries and control the female menstrual cycle. An average menstrual cycle lasts 28 days. During the first part of the cycle, the lining of the uterus thickens. Around day 14, of the cycle of a female egg is released from the ovary into fallopian tube, a process called ovulation. If the egg is not fertilised by a males sperm, it will be expelled with the lining of the uterus as a menstrual bleeding. The testes produce the male sex hormone testosterone, which stimulates sperm production. Sperm are made in the testes and stored in the epididymis. When a male becomes sexually aroused, his penis becomes erect and sperm are released from the testes. During sexual intercourse, sperm are deposited in the vagina and swim up through the female reproductive system to reach the fallopian tubes.
If sexual intercourse takes place during this time when the egg may become fertilised by a male sperm in the fallopian tube. The fertilised egg starts to develop into an embryo and begins to grow rapidly. The growth and development of the baby in the uterus is one of the most eventful periods of human growth and development.

First trimester.
The first 12 weeks of pregnancy are referred to as the first trimester. The starting point of the trimester is the date of the mother's last menstrual period. Once fertilised ovum has implanted in the wall of the uterus, the embryo begins to grow and develop. this is a critical time in the pregnancy. The growing embryo is nourished directly from time in the mothers blood through placenta to which is attached by the umbilical cord. The embryo receives both nutrients and oxygen in this way, so does not breathe normally or need to digest food. It is protected in the uterus within the amniotic sac, surrounded by amniotic fluid. This is protective environment keeps the embryo at a constant temperature and helps to prevent some infections.
Second trimester.
Between weeks 12-25, it is a period of rapid foetal growth and from about week 20 and 25. By week 24 the foetus is considered to be viable, or to survive on its own outside of the uterus. At this stage, an average foetus measures 21cm and weighs 700g. Most woman will appear noticeably pregnant during this trimester.
Third trimester.
From week 25 until full term between 37 and 42 weeks. The foetus grows very rapidly during this time, in preparation for birth and life outside of the uterus. Towards the end of the third trimester, the baby will settle low in the uterus with the head facing downwards. Occasionally,, the baby will settle, with its bottom legs and feet facing downwards. Many woman experience backache at this stage because the foetus is heavy.

The process of birth is called 'labour' and is well named; the woman's body works hard to push the baby out of the uterus. Birth is the first big event in every human beings life. At 9months of rapid foetal development culminates in the moment when a new baby enters the world. labour begins with contractions which is the muscles of the uterus tighten up and get ready to push the baby out. Labour is divided into three stages.
Stage one; is characterised by steady contractions of the uterus that open the cervix wide enough for the baby to pass through.

Stage two; begins when the cervix has fully opened and involves the strong and frequent contractions that push they baby out. stage two is the very active stage of labour as the woman pushes with each contraction. she is usually encouraged to use special breathing techniques A special moment comes when the baby's head becomes visible.

Stage three; consists of expelling the placenta from the uterus. It is usually a straightforward process guided by the midwife and requires little effort from the mother.
After the baby's birth, mucous is cleared from the baby's nose, moth to allow him or her to take a first breath.

Infancy is probably the most dynamic phase of growth and development in the human life course. The rapid growth and development that begin at conception and which continued through 9months of foetal development shows little signs of slowing when a baby is born. physical change during 3 years of life transforms an infants appearance. infants grow taller and generally gain weight quickly. first 18months of life, an average infants body weight triples. Physical change occurs from head downwards which is known for the (cephalocaudal) and from middle of the body outwards (proxmodistal). An infant first develops gross motor skills. In later stages of infancy, children begin to develop fine motor skills. These are more sophisticated and finely controlled forms of movement.
The physical growth and changes that occur in early infancy provide an essential foundation for various forms of growth and development that occurs later in the human life. These changes include: brain growth, enabling the infant to develop language and thinking skills, later giving the child the ability to build relationships and use social skills and ossification of the baby's soft bones allowing independent movement and making the infant physically robust..

During childhood, individuals gradually become less physically dependent and immobile and more physically capable and competent. The pace of physical change experienced by the human body is slower than childhood. Children gradually develop greater awareness of who they are and how they are similar to different from others. A child can usually identify their own sex by 2 years of age. A childs sense of who they are is relatively simple. In early childhood, children, don't tend to reflect on their self-worth. They tend to think about who they are in terms of their visible characteristics and can say how good they think they are at familiar physical, intellectual and social tasks. By the end of this stage, children usually have an awareness of their own internal qualities, beliefs and personality traits. Relationships with friends become increasingly important during childhood. in fact, by the middle of childhood many children prefer to spend time with peers rather than their parents

Adolescence is often seen as an emotionally difficult and stormy life stage. Teenagers hormones are often blamed for their moodiness and emotional sensitivity. Two of the key emotional concerns of adolescence was: coping with the physical effects of puberty and forgoing a sense of personal identity. Adolescence tend to need reassurance about their growth patterns. They may seek this from development and physical maturation during this life stage. Late maturation can damage self-confidence and self esteem in some adolescence who may be tested or bullied. Relationships in this stage of life, play a very important role in social and development. Friendships are more stable and adolescence spend more time with their friends more than family.

This stage is the stage where you typically leave home to live independently of their family in early adulthood. Often young adults make new friendships through work and social life. New responsibility are put into place. Although the timing of the major life events that occur in early and middle adulthood vary substantially across individuals, they nevertheless tend to follow a general sequence, known as a social clock which is, the culturally preferred “right time” for major life events, such as moving out of the childhood house, getting a job, getting married, having children, and owning your own home.
Parenthood is also a common feature of early adulthood. For most people it appears to be an experience that brings profound satisfaction. The multiple roles of adulthood which are, parent, partner and worker, change as an individual progresses through this life stage. Relationships, especially partnerships, are likely to be given more time and a new significance. Partnership satisfaction trends to rise in mid-life.

Later adulthood is a time when there is changes in roles and relationships are experienced. Later adulthood is a time when considerable changes in roles and relationships are experienced. Many long-standing roles are shed. the roles of worker is largely lots of people retire. some experience tragic deaths of their partners or children. partnership relationships in later life tend to be based on loyalty, familiarity and mutual investments in the relationship. Many older people see their adult children regularly for purposes of practical help and emotional support.
