Hi, everybody!
Sperm is tiny cells created by the male reproductive organs. that is made mostly of water, plasma, and mucus. It also contains 5 to 25 calories and is made up of small amounts of essential nutrients including Calcium.
Males produce millions of these cells each day, yet it takes only one to fertilize an egg and create a life!
Is human sperm visible?
Yes! but Only if you're looking through a microscope. Sperm are tiny. Like really tiny
scientists can typically identify the following three parts When studying a sperm cell under a microscope
The sperm head contains chromatin, which is the DNA material that makes up chromosomes.
Typically, both the human sperm cell and the human egg cell each contain 23 chromosomes. When the sperm and egg combine, this results in an embryo cell with 46 chromosomes.
Covering the head of the sperm is a cap called an acrosome. The acrosome contains enzymes that help the sperm penetrate the outer shell of an egg.
The head shape is important because it can affect the sperm’s ability to penetrate the outer surface of a woman’s egg to fertilize it.
The midsection of the sperm contains energy-producing mitochondria. These specialized structures provide the energy necessary for the sperm cell to move.
The sperm tail is the most complicated structure with more than 1000 proteins involved in its functioning. scientific, Over 300 years ago, described sperm tails swaying in a symmetric pattern, like “that of a snake.
With the advent of three-dimensional microscopes, Most recent studies have shown that sperms move by spinning rather than swimming, The sperm almost seemed to be drilling into the surrounding fluid.

Normal Vaginal Childbirth and birth Canal

Normal Vaginal Childbirth and birth Canal Fakty Jebać fałsz 2 צפיות • לִפנֵי 3 שנים

Traumatic brain injury from Induced labor and autism.
During pregnancy, the baby is held securely inside a mother’s uterus for the full term of the pregnancy, by the strong muscular wall of the lower end of the uterus called the cervical canal. The fluid-filled membranous amniotic sac protects the baby from external trauma of any kind. When the baby is ready to be delivered, occasional minor contractions begin causing the strong muscular cervical canal to start to thin out. The amniotic sac may rupture, which typically brings on active labor, characterized by stronger contractions at a higher frequency.
During birth, once active labor begins the cervical wall begins to thin out rapidly in a continuous feedback loop process of contractions and cervical effacement. In a normal delivery, the cervical wall takes anywhere between 15 minutes and 3 hours to efface and eventually disappear,
However, in some mothers, the cervix is not ready and none of these processes begin even after the due date. In some others, they begin and then get stuck in the middle. This might be due a natural protective mechanism in the mother to protect the fetal brain from damage. When the cervical wall is not ready to efface, contractions do not begin or back off, so that they do not damage the baby's head and brain by hammering it against a rigid cervical wall.
However, modern oxytocin-based labor induction does just the opposite. It brings on strong contractions even when the cervix is not ready to efface. This results in brain damage to the baby by strong contractions hammering the head against a non-effacing cervix. When induction is pursued for long hours in such cases, the cervix wall might eventually dilate, but the baby is significantly brain damaged by then. When cervical dilation finally reaches 10 centimeters after prolonged induction the next pushing phase is reached.
Here as the baby pushes through the birth canal passing through the maternal pelvic bones, the head and brain are subjected to a big squeeze. The squeezed head deforms to take on a conical shape. This is especially the case for the first child of a new mother. Such deformation from the squeeze actually has the effect of blotting out any scarring and damage in the previous phase, preventing it from showing up on MRI scans. Thus, the pushing stage effectively erases any brain damage from MRI visibility.
Unfortunately, such traumatic damage to the brain is fairly permanent and the damage to brain white matter and the blood brain barrier have further negative effects as the baby grows up, resulting in neurodevelopmental disorders we call autism.

Alcohol increases acid in the stomach| Dandelion Team

Alcohol increases acid in the stomach| Dandelion Team Fakty Jebać fałsz 3 צפיות • לִפנֵי 3 שנים

After alcohol leaves the mouth, it flows down the esophagus and into the stomach.
If there is no solid food in the stomach, most of the alcohol moves down into the small intestine and will come into contact with the intestinal walls more easily and pass quickly into the blood.in this way, All the alcohol of one drink may be absorbed within 30 minutes. If one drinks alcohol with food in the stomach, it will be trapped with the food in the stomach, where absorption is not very efficient. it can’t move into the small intestine immediately, this, slows the absorption of alcohol into the bloodstream considerably. and the person will become impaired more slowly and will reach a lower peak alcohol concentration. also, Alcohol increases acid in the stomach, which in alcohol abusers can lead to severe stomach pain or sores in the intestines. This is why it is a good idea to eat a nice big meal while you are drinking. In fact, The presence of fatty meals can significantly reduce the peak blood alcohol concentration (BAC) up to 50% relative to that produced when alcohol is consumed on an empty stomach.
