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.
What harmful substance can pass through the placenta to the foetus?
Ellicit drugs, alcohol and nicotine.
How the smoke travel from the mouth to the developing baby?
Through the placenta via the umbilical cord to the foetus.
How might the harmful substances of the foetus come to be at the placenta?
Harmful substances can reach the placenta through various pathways, primarily via maternal circulation. Substances such as drugs, alcohol, environmental toxins, and certain infections can cross the placental barrier, often due to their small molecular size or lipid solubility. Additionally, maternal health conditions or behaviors, such as smoking, can further elevate the levels of these harmful substances in the bloodstream, ultimately exposing the developing fetus. This transfer can have detrimental effects on fetal development and health.
What is an amoniotic sac?
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
What fluid burns a baby?
The amniotic fluid in the womb cushions the developing foetus from being physically damaged.
What surrounds the baby during pregnancy?
You have the amniotic fluid that surrounds the baby. Baby go on drinking this fluid and go on passing the same through the urine.
Which structure provides nutrients and oxygen for a developing foetus?
The placenta is the structure that provides nutrients and oxygen for a developing fetus. It is connected to the uterine wall and facilitates the exchange of gases and nutrients between the mother and the developing baby.
What is human fetal development?
A human fetus is a unborn human.A human foetus is a baby developing inside a woman's womb.
Name 2 ways in which harmful substances can be passed onto the foetus?
To my knowledge there is only one way. Across the placenta and into the foetus. Everything taken into mothers body will pass across the placenta, around the system of the foetus and even returning waste back across the placenta through the magic of Osmosis.
Is the SRY gene responsible for testosterone?
Indirectly. The SRY gene is responsible for activating the gene responsible for testosterone production (thereby causing 'maleness' in a developing foetus).
What process moves nutrients from the mother to developing foetus?
In mammals this is done by the placenta, through which the foetal blood flows and exchanges nutrients/gasses with the mothers blood supply.
