Life cycle of the Liver Fluke: Fasciola hepatica
This video of the life cycle of the globally significant parasite of sheep and cattle; the liver fluke, Fasciola hepatica was produced in collaboration with parasitologist Dr Clive Bennett (University of Southampton, retired)
This video shows state of the art microscopy of the different stages of development throughout the life cycle including larval stages, mollusc infection and the hatching of juvenile flukes that cross the gut of sheep and cattle and migrate to the liver. We see the adult flukes living in a simulated bile duct, stages that we cannot normally see.
This video shows the enormous biotic potential of Fasciola sp. and what livestock farmers are up against to control its spread and severity.
Much more rarely it can also infect humans.

From the Cervix to the Uterus

As the sperm cells complete their journey through the cervix the enter the relatively vast vault of the uterus. The cervix and uterus are lined with cilia and cells that manufacture mucus and serous secretions.This is a sperm point of view shot created using a large scale model of the cervix.

Cervical Crypt
Переглядів 18 тис.9 років тому
The cervix contains many fissure and folds called cervical crypts. This folded structure along with the elastic nature of the tissue helps the cervix to expand greatly when necessary. This area provides a changing environment that filters out unhealthy or malformed sperm, yet nurtures healthy cells. It blocks infection from the outside world and will only allow sperm to pass when the female is ...
Sperm swimming in the Fallopian Tube

Once Sperm cells have reached the Fallopian Tube they have to find the ovum. The Fallopian tube is densely lined with cilia and cells that manufacture mucus and serous secretions. These secretions provide the optimal environment for both the sperm cells and the egg cell. The cilia along with muscular contractions of the tube drive the ovum towards the uterus. This is a silicon model of the cerv...

This is a silicon model of the cervix and the Fallopian tubes made for the Discovery Channel program: "Curiosity: Life before Birth" produced by Pioneer Productions.

The elephant is the largest land mammal. The gestation period is 660 days or 22 months. An adult bull elephant can weigh 6 metric tonnes. The larges, african elephants can stand up to 4 meters high at the shoulder. A 20 kilogram heart pumps 450 litres of blood around the body for sixty years. The heart beats at 28 beats per minute compared to 70 per minute for a human and 500 per minute for a m...

Ferning In Cervical Mucus
Переглядів 10 тис.9 років тому
At ovulation the cervix secretes a very clear mucus that is receptive to sperm cells but also acts as a filter to weed out bacteria and unhealthy sperm cells whilst nurturing the healthy ones. The change in the mucus at this time is characterised by an increase in Sodium salts. As a result, it produces these rather beautiful fern-like crystals within it as it dries. This only happens around ovu...

    Allah say in surah el nahl(which mean bee in ): Your Lord inspired the bee, saying: "Set up hives in the mountains and in the trees and in the trellises that people put up, then suck the juice of every kind of fruit and keep treading the ways of your Lord which have been made easy." There comes forth from their bellies a drink varied in colours, wherein there is healing for men. Verily there is a sign in this for those who reflect. Then allah who inspired this fluckes and every thing in our life❤

    Doesn't fail, watching how the puddles of sweat just dried up within 48 hours was so satisfying, I used what I read about the other day. Although it actually took about 72 hours for my sweating to normalize, I went ahead and go'ogled Cynthia Yulesin’s Stop Sweating Today and I don’t have to change clothes 2 times a day.

    Scary in a way. Imagine an entire lifeform with stem cells based off the HeLa template instead of just regular ol' stem animal cell. Or any cell based on a mutation from a smidgoen of any viral DNA piece added due to good ol fashioned covalent bond or whatever it is.

    why does the vessel go thicker so intensely in this video? some chemical response of human body? or body temperature or mechanical stress?

    • @davidbarlowarchive
      @davidbarlowarchive 8 місяців тому

      Blood vessels dilate because smooth muscle in the walls respond to chemical stimuli released into the blood by the body in response to many external and internal stimuli. This video looks fast because the process has been filmed with time lapse photography. Having said that, it can still be quite a quick process as in blushing which is a result of small blood vessels in the face all dilating at the same time.
