The menstrual cycle is a (a) -controlled monthly cycle:
1. (b) development and ovulation
2. Preparation of the (c) for implantation and (d)
3. Cycle pauses for pregnancy, (e) develops
4. Cycle ends with release of uterine lining (menstruation/ bleeding)
The (a) is an extension of uterine wall. It connects to the umbilical cord and allows (b) and O2/CO2 to (c) back and forth between mother and (d) (blood never mixes).
(a) occurs when the blastocyst (b) to the (c) wall.
Fertilization occurs when a (a) cell joins an egg (b)
=> (c) cell is formed.
Meiosis is the creation of (a) (sex cells) that half one set of (b) material to produce offspring.
* (c) in males
* (d) in females
*Haploid cells = (e)
Estrogen and (a) are the sex hormones in (b) . They regulate the female (c) cycle.
Testosterone is the sex (a) in males. It develops (b) characteristics and controls the (c) system.
Risks to a healthy pregnancy...
smoking
drugs
alcohol
injury to abdomen
obesity/high blood pressure
radiation
lack of nutrients/water
blastocyst attaches to uterine wall
Hormone-controlled monthly cycle:
Egg development and ovulation
Preparation of the uterus for implantation and pregnancy
Cycle pauses for pregnancy, placenta develops
Cycle ends with release of uterine lining (menstruation/ bleeding)
extension of uterine wall
=> connects to the umbilical cord
=> allows nutrients and O2/CO2 to diffuse back and forth between mother and baby (blood never mixes)

Fertilization...
sex hormone in females;
regulate the female reproductive cycle
Creation of gametes (sex cells) that half one set of genetic material to produce offspring.
