Conception, pregnancy and birth

A human life start at the point of conception, the women usually produces 1 egg cell per month, 2 weeks after the menstruating the egg then travels from the ovary to the fallopian tube then in to the uterus. if sexual intercourse happens when the egg is in the fallopian tube it may become fertilized by 1 sperm out of millions.(sperm = 23 chromosomes, egg = 23 chromosomes) when the sperm meets the egg the path of physical development start as the genetics from the mother and father become joined as one.

At 2-3 days the egg is the size of a pin head and starts to travel and attaches itself to the wall of the uterus.

At 8 weeks the foetus is normally 3-4 cm and has a heart beat as well as developing arms, legs, eyes, ears and mouth ect.

At 12 weeks the foetus (baby) is about 5 cm long and weighs less then 14g.
Baby will start moving around and there face is becoming to look more human, there eyes have moved closer together and there organs are starting to performing more tasks like the kidneys are secreting urine into there bladder.

At 20 weeks the baby is putting weight on and is half the length they will be at birth.

    In the first month the amniotic sac and placenta develop along with a face, mouth, jaw, and throat. The embryo also develop blood cells and a heart tube. In the second month, ears, fingers, toes, and eyes begin to form. The arms and legs also begin to form during this stage. The nervous system, digestive tract, and sensory organs develop in these first six weeks and bone begins to replace cartilage. During the third month the arms, hands, fingers, feet, and toes are fully developed. The fingernails and toenails develop along with the beginnings of teeth. The fetus is fully formed after the first three months which is the most critical stage of development in a pregnancy. After the first twelve weeks, a chance for miscarriage drops…

    The fetal stage, also known as prenatal development, is a stage of life that so much can occur. Humans begin life as a single cell. There are multiple stages that have to happen in order to become a "human." The first stage is known as the Germinal Stage. The Germinal Stage is from the conception to implantation which is from 0 to 2 weeks. This is the period when cell division occurs, the zygote reaches the uterus and begins to implant on the uterine wall. The process of implantation can take up to a week. Our next stage is the Embryonic Stage. This stage is from implantation till the end of the first two months. Some of the things that occur in this stage are, vital organs and bodily systems begin to develop from the embryonic disk. The nervous system, sensory organs, hair, outer skin, digestive and respiratory systems, liver and pancreas, bones, and muscles are all beginning to develop. At 7 weeks genetic activity on the Y chromosome causes testes to differtiate, meaning if there is no Y chromosome then ovaries will differentiate. Stage 3 is the fetal stage, which is from the third month until birth. There is so much that happens during this time. By the end of the second trimester I felt fetal movement, the eyes begin opening and closing, thumb sucking, and the pattern of sleep begins. By the end of the third trimester, the fetus typically weighing 6-7lbs and around 20in long. The survival rate increases to…

    Just 1 short week after fertilization, the egg burrows itself into the mother’s uterus. For the rest of the 1st trimester, the cell grows at an astronomical rate. At 4 weeks the blastocyst, as it is now called, is the size of a grain of rice, and is now forming a heart, spine, arms, and legs. At 23 days the heart begins to beat. At 8 weeks, all of the organs are in place, and the organism is now called a fetus. 10 weeks, the fetus can feel. 13 weeks, the baby can make expressions and is developing its own unique finger and toe prints. At 26 weeks, the baby can now taste, squeeze its hand, respond to light, hear sound, and most critically, has a…

    Infants (birth to age 1) and toddlers (ages 1 to 2) grow quickly; bodily changes are rapid and profound. Physical development refers to biological changes that children undergo as they age. The first 4 weeks of life are termed the neonatal period. Most babies weigh between 2.5 and 4.5kg, and are between 45 and 55cm long. Male babies are generally slightly heavier and longer than female babies. Both premature and postmature babies are at higher risk of complications such as sickness, brain damage, or death, than are full-term babies. Physical growth is especially rapid during the first 2 years. An infant's birthweight generally doubles by 6 months and triples by the infant's first birthday. Similarly, a baby grows between 25 and 30cm in length (or height), and the baby's proportions change during the first 2 years. The size of an infant's head decreases in proportion from 1/3 of the entire body at birth, to 1/4 at age 2, to 1/8 by adulthood. Fetal and neonatal brain developments are also rapid. The lower, or subcortical, areas of the brain (responsible for basic life functions, like breathing) develop first, followed by the higher areas, or cortical areas (responsible for thinking and planning). Most brain changes occur prenatally and soon after birth. At birth, the neonate's brain weighs only 25% of that of an adult brain. By the end of the second year, the brain weighs about 80%; by puberty, it weighs nearly 100% of that of an adult brain. Because infants cannot endure on their own, newborns have specific built-in or prewired abilities for survival and adaptive purposes. Reflexes are automatic reactions to stimulation that enable infants to respond to the environment before any learning has taken place. For instance, babies automatically suck when presented with a nipple, turn their heads when a parent speaks, grasp at a finger that is pressed into their hand, and startle when exposed to loud noises. Some reflexes, such as blinking, are permanent. Others, such as…
