Fertilization occurs when a sperm cell from a male merges with an egg cell from a female, resulting in the formation of a zygote. This single-celled zygote undergoes a series of cell divisions, known as cleavage, as it travels down the fallopian tube to the uterus. Once in the uterus, the developing structure, now called a blastocyst, implants into the uterine lining and begins the process of embryonic development. Over approximately nine months, the embryo grows and differentiates into various tissues and organs, eventually forming a fully developed fetus.
What else can I help you with?
Describe in detail the site of blood formation in foetus and adults?
In the fetus, blood formation occurs mainly in the liver and spleen during the early stages of development and later shifts to the bone marrow. In adults, blood formation primarily takes place in the red bone marrow of the axial skeleton (such as the sternum, ribs, vertebrae, and pelvis) and proximal epiphyses of the long bones (such as the femur and humerus). The bone marrow contains stem cells that differentiate into various blood cell types, including red blood cells, white blood cells, and platelets.
What is the name of the organ system in the mothers body?
the aminotic fluid that the foetus gets before its born and when its a foetus
What is teratogen?
A teratogen is any substance or factor that can cause birth defects or developmental abnormalities in a growing fetus. These can include drugs, chemicals, infections, and other environmental factors that can negatively impact the development of the embryo or fetus during pregnancy.
What is an amoniotic sac?
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
What is the difference between mutagenic and teratogenic substance?
I found your question while google-ing this question myself! The answer is:A teratogen is an exogenous substance that interferes with normal development of the foetus. A mutagen, on the other hand, directly affects and disrupts DNA by causing an increase in the rate of change in genes. These mutations can be passed along as the cell reproduces, sometimes leading to defective cells or cancer. Some agents, such as ionizing radiation, are teratogens and mutagens; ionizing radiation can cause defects either in development or it can damage DNA directly. Examples of mutagens include certain biological and chemical agents (cigarette smoke) as well exposure to ultraviolet light or ionizing radiation. Examples of teratogens include alcohol, rubella virus, cytomegalovirus and hyperthermia.So, a foetus that has developmental abnormalities due to a teratogenic substance has normal genes, but the development was disrupted and altered by the presence of the teratogen. A foetus that was exposed to a mutagenic substance has genetic abnormalities.
What is first embryo or foetus?
An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
How developed is the foetus at 6 weeks?
Up to 8 weeks after fertilization embryo is present which is unborn baby in early stages while foetus is an unborn baby in uterus in later stages of development (after 8 weeks till birth).
After how many weeks can an embryo be called a foetus?
An unborn baby that is less than 8 weeks old, is an embryo, after this it is classified as a foetus.
What develops into the fetus?
A Foetus is formed by the growth and development of an embryo.
What would happen to the embyro in gestation?
The embryo will develop into a foetus in the womb.
What is a 6 letter word for beginning of a baby?
Infant.Zygote, Embryo, Foetus.
How do babies become embryos?
Babies don't become embryos, it's the other way around. A fertilised egg becomes a zygote, a zygote becomes an embryo, an embryo becomes a foetus, a foetus becomes a baby.
What is fully developed a fetus or an embryo?
Well, embryo is the developing stage of a zygote(fertilised egg) when it repeatedly divides itself into a ball of cells to form the different tissues and then the organs of the baby. The stage when the hands, legs , and different body parts of the baby can be identified is termed as the foetus. So, in accordance with your question the stage of the foetus is more developed. However the foetus is not the fully developed stage. The foetus once completely developed , the baby is born.
What is a baby-to-be?
A baby-to-be is an unborn child, a child which has not yet been born - an embryo or foetus.
What is a fetus and what is its function?
A Foetus is formed by the growth and development of an embryo. A Foetus is an unborn baby in the uterus in the later stages of development (after 8 weeks till birth). A Foetus is also multicellular. The body features of developing baby can be identified.
When the fertilized ovum implants in the uterine lining it becomes?
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
What is the differences between embryo and a foetus?
An embryo is the early stage of development in a multicellular organism, specifically from fertilization until about the eighth week of gestation in humans. During this period, the basic structures and organ systems begin to form. After the eighth week, the developing organism is referred to as a fetus, which continues to grow and mature until birth. The transition from embryo to fetus marks a significant phase in development, characterized by more complex growth and differentiation of tissues and organs.
