25
The production of offspring; in general humans copulate purely for the purpose of procreation
Procreation
26
TWO RELATED THEORIES FOR PROCREATION
CREATION AND EVOLUTION
27
God created the world and all that's in it, including humans, and they reproduce through sexual intercourse
Creation
28
Darwin's theory that humans evolved over the years through natural occurrences and from the growth and development of monkeys and other creatures
Evolution
29
This happened during sexual intercourse
some sperm ejaculated from the male penis swim up through the female vagina and uterus toward an oocyte (Egg cell) floating in one of the uterine tubes
30
Fertilization takes place where
ampula (outer 1/3) portion of the fallopian tube
31
The sperm and egg are ___
gametes
32
the sperm and egg contain half the ____ necessary for production. When a sperm cell penetrates and fertilizes an egg, that genetic information combines
genetic information
33
The 23 chromosomes from the sperm pair with 23 chromosomes in the egg, forming a 46- chromosome cell called a
zygote
34
___ Starts to divide and multiply. As it travels toward the uterus it divides to become a ___, which will burrow into the uterine wall
zygote ; blastocyst
35
A fertilized egg, or zygote takes about how many days to reach the uterus from the uterine tube
Five days
36
As the zygote moves, the zygote divides and develops into a ___, with an inner mass of cells and a protective outer ring
blastocyst
37
attaches to the wall of the uterus and gradually implants itself into the uterine lining
blastocyst
38
During implantation, its cells differentiate further. At day 15 after conception, the cells that will form the embryo become an
embryonic disc
39
the___, on one side of the disc, will become part of the digestive tract
yolk sac
40
As the cells multiply, they will also separate into two distinctive masses:
1. the OUTER CELLS will eventually become the placenta and umbilical cord, which will bring in nutrients and eliminate waste and
2. the inner cells from the embryo
41
On the other side, the ___ fills with fluid and will surround the embryo as it develops
amnion
42
By week 4, the embryo ____
the embryo has a distinct head and tail and a beating heart
43
Over the next six weeks, _________ form. Primitive versions of all body systems appear
limbs, eyes, brain region, and vertebrae form
44
In eight weeks, the embryo develops
contains a flat embryonic disc that now differentiates into three layers:
endoderm, mesoderm, ectoderm
45
skin and nervous system
ectoderm
46
digestive and respiratory system
Endoderm
47
Muscle and skeletal systems
Mesoderm
48
All organs of the human body derive from these three tissues called___. They begin to curve and fold and to form an oblong body
Ectoderm, Endoderm, Mesoderm
49
10th week of pregnancy
your baby will change names from an embryo to a fetus. There are about 40 weeks to a typical pregnancy. These weeks are divided into three trimesters
50
Pregnancy is often measured in terms
gestational age
51
age of the fetus starting with the first day of a woman's last menstrual period
gestational age
52
actual age of the growing fetus.
embryonic or fetal stage
53
STAGES OF FETAL DEVELOPMENT
Ovum- from ovulation to fertilization
Zygote - (12-14 days after fertilization) from the time the ovum is fertilized until is is implanted in the uterus
Embryo- from implantation to 5-8 weeks. During this period, embryo is most vulnerable to teratogens: viruses drugs radiation or infection can cause major congenital anomalies
Fetus- 8-10 weeks until term(38-41 weeks)
54
from ovulation to fertilization
Ovum-
55
(12-14 days after fertilization) from the time the ovum is fertilized until is is implanted in the uterus
Zygote -
56
from implantation to 5-8 weeks. During this period, embryo is most vulnerable to teratogens: viruses drugs radiation or infection can cause major congenital anomalies
Embryo-
57
8-10 weeks until term(38-41 weeks)
Fetus-
58
is the developing embryo or fetus and placental structures throughout pregnancy
Conceptus
59
the earliest age at which fetuses could survive if they were born at that time, generally accepted as 24 weeks, or fetuses
Age of viability
60
During intra uterine life the fetus derives _______, not from O2 exchange in the lungs but from the ____
O2 and excrete carbon dioxide ; placenta
61
is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy
fetus
62
How does fetus receive all the necessary nutrition, oxygen, and life support from the mother through the placenta
through the blood vessels in the umbilical cord
63
Where the gas exchange takes place during fetal life
Placenta
64
carry unoxygenated blood from the fetus to the placenta
Umbilical arteries
65
Brings oxygenated blood coming from the placenta to the fetus
Umbilical vein
66
Connects the left and the right atrium. It pushes blood from the right atrium to the left atrium so that blood can be supplied to brain, kidney, and heart.
Foramen ovale
67
Carry oxygenated blood from umbilical vein to inferior venacava, by passing fetal liver
ductus venosus (vein to vein)
68
carry unoxygenated blood from the pulmonary artery to aorta, by passing
Ductus arteriosus (artery to artery)
69
FETAL CIRCULATION
The oxygenated blood enters the umbilical vein from the placenta -> enters ductus venosus that connects the umbilical vein to the inferior venacava, w/c allows oxygenated blood to be supplied directly to the fetal liver -> it passes through inferior venacava -> enters the right atriums (heart) -> enters the foramen ovale (opening bet. rt. atrium and left atrium)
-> goes to the left atrium -> passes through the left ventricle -> flows to ascending aorta to supply nourishment to the brain and upper extremities -> it enters superior venacava (return to the heart) goes to the right atrium -> enters the right ventricle -> enters pulmonary artery with some blood going to the lungs to supply oxygen and nourishment -> it flows to ductus arteriosus (channel bet. aorta and main pulmonary artery) Allows blood to bypass the fetal lung. It closes during normal respiration -> It enters descending aorta (some blood going to the lower exteremities) -> and enters hypogastric arteries that return the blood to the placenta (unoxygenated blood because it is away from the fetal heart) -> and goes back to the placenta
70
During pregnancy, the pregnant mother undergoes significant anatomical and physiological changes in order to:Wh
nurture and accomodate the developing fetus
