A fetus actually stays more vertical with head up toward the ribcage, or stays horizontal across (within) the uterus throughout the 9 months of gestation. Many women complain of feeling the baby kicking the mother's side(s) and some moms say they feel their fetus doing a roll or flip as they stretch and move arms and legs.
In the weeks before a woman's due date for delivery, the fetus begins to turn to the "head down" position, except in breach cases when the fetus fails to turn head down. Gravity and pre-labor uterine contractions (Braxton-Hicks) help move the baby further down. The head must enter the pelvic opening long before true labor begins (doctors might say the head is engaged or has dropped, meaning the head is sitting within the opening of the pelvic bones). As the mother continues her daily routine, and with the aide of uterine muscles influenced by drops in certain hormones, the baby continually pushes against the inside of the cervix, helping it to "efface" or "soften".
You've asked why the fetus doesn't experience blood "rushing to its head" because of the upside-down position. First, the movement downward is slow, over days to weeks, so the baby adjusts to the "head-down" bloodflow, much like astronaunts become acclimated to weightlessness over time. Second, a normal fetal and neonate (just after birth) and the infant's heart rate is much higher than a "normal" for an adult. While adults have a normal heart rate of about 80 (give or take 10 beats), a fetal to infant's heart rate is normally 140 to 160. This keeps the fetus well-perfused (i.e. an adequate amount of circulating blood) to the brain and all extremeties and vital organs, regardless of the position within the womb.
There can be complications during the 3rd trimester or during labor/delivery that can severely impede fetal blood flow, but normally women are well-monitored so that the majority of complications are found quickly and corrected quickly.
no it effects your blood because if you sleep upside down blood comes down to your brain.
First of all, the sensation of "blood rushing to your head," is actually not blood. It's a fluid, (mostly water) from the vestibular sacs in your inner ear. When your body is upside down, that fluid moves around, giving you the sensation of being upside down, and feeling liquid run to your head. But no blood ever actually goes to your head. But can you die from it? It's not immediately dangerous, but our bodies weren't designed to be upside down for extended periods of time, so I wouldn't recommend it for more than a few seconds.
The reason why is because when the heart pumps all that blood, it has to go somewhere. So it goes through your legs and arms and stays there I guess. So when you go upside down, the blood will go down and eventually go down into your brain. That's why it isn't good for someone to stay upside down for a long period of time.
If upside down, your blood flow to your head due to gravity.
because they need the blood flow to their brain
They flash it down the toilet. Its just a a pile of blood.
There is a risk of asphyxiation of a person hangs upside down for too long. The blood can leave the vessels causing oxygen to not circulate properly. There is not a risk if a person is healthy hanging upside down for short periods of time.
Its 7up just upside down !
no. thats just weird.......................
Yes, all of your blood goes to your head.
The earth can not be upside down.
if you are upside down then more blood will be rushed to your head due to gravity
