Flashcards in Unit 2 Sac 1 Deck (21):
1

Conception

The point where sperm and ovum fuse to create new life

2

Germinal Stage

The first stage of pre-natal development measured from the moment of conception until implantation
(Conception to end of week 2)

3

Embryonic Stage

The second stage of pre-natal development measured from implantation until the end of week 8 after conception
(week 2 trend of week 8)

4

Foetal Stage

The third stage of prenatal development measured from the end of week 8 until birth.

5

Placenta

A vital organ that supplies oxygen and nutrients to the developing embryo and removes waste products

6

Maternal Morbidity

Is the ill health experienced by woman during their pregnancy or as a consequence of giving birth

7

Maternal Mortality

Refers to the death of a women during pregnancy or within 42 days of the termination of pregnancy from any cause related to or aggravated by pregnancy

8

Prenatal Morbidity

Determining whether an unborn baby has health complications or not

9

Prematurity

Having a baby before its due date, can cause long term morbidity or long term disabilities

10

Congenital Anomalies

Structural or functional defects that occurs during foetal development and are present at birth

11

Perinatal Mortality

Deaths that occur to babies before birth or within 28 days of birth

12

Germinal Stage (major developments)

- The first split, first divides into 2 cells after 24 hours (Zygote)

- After 4 days it keeps dividing into 32 cells (Morula)

-Cells start to differentiate, which makes up the embryo, placenta and chorion

13

Embryonic Stage (major developments)

-Placenta is fully formed

- All major body systems establish in this stage (critical period)

14

Respiration

Foetus relied on Placenta for oxygen supply and CO2 removal during pregnancy, the neonate during finals weeks of pregnancy prepares for its first breath. Once the umbilical cord is cut, the neonate must take its first breath to inflate the lungs

15

Circulation

During pregnancy the placenta fulfils the role of the lungs and liver as they are not fully functioned yet. When infant takes it first breath, it inflates the lungs increasing blood supply; the opening left and right side of the heart closes off causing a change in blood flow through heart

16

Digestion and Waste removal

When neonate is still in the mother, it obtains vital nutrients via placenta. The baby must adapt to digesting and drinking milk. After birth lungs excrete C02 and kidneys purity blood.

17

Temperature Control

Amniotic fluid assist in the womb to keep a constant warm temperature, prior to birth the babies temperature drops

18

Low Birth Weight

Body systems aren't functioning properly like respiratory, immune and circulatory systems.

Complications of low birth weight are:
- Lung disease
- Feeding difficulties (not able to suck or swallow)

Government initiative: Healthy mothers, healthy babies

19

FAS

With high levels of alcohol consumption, baby can experience mental and physical defects

Alcohol in placenta can cause disability and growth and weight defects

Government initiative:
Alcohol, think again

20

Gestational Diabetes

Puts mothers at risk of premature delivery, hypertension cardiovascular disease

Government initiative:
Diabetes Australia

21

Spina Bifida

A congenital disorder caused by incomplete closing of neural tube
Some risks are bowel and bladder problems, bone growth and leg functions

Government initiative:
Spina Bifida Hydrocephalus
