4. Render the text into English.

Гистология – наука о структуре тканей, определяемых как группы или слои клеток, которые вместе выполняют определенные функции. Как самостоятельная наука гистология была основана сравнительно недавно, и с тех пор успешно развивается. Ткань животных – группа клеток, а также межклеточного вещества, имеющих одинаковое происхождение, строение и функцию. Морфологи обычно выделяют четыре типа тканей: эпителий – покровный (плоский), железистый (кубический), мерцательный (ресничный), всасывающий (цилиндрический); соединительная (плотная, рыхлая, хрящевая, костная, кровь); мышечная (гладкая, поперечнополосатая); нервная. Все ткани образуются из зародышевых листков при их дальнейшей дифференциации и специализации.

Supplementary texts Most cot deaths due to "natural causes"

Parents are advised to put babies to sleep on their backs. Doctors continue to investigate exactly what causes cot death, but say the majority of cases are due to natural causes. Each year, around 600 babies die in England and Wales between one week of age and their first birthday.

That works out at around one baby in every 1,600 dying of cot death each year. Around ninety per cent of deaths occur in babies aged under six months. Unfortunately, there is a current eagerness by some to view all sudden and unexpected deaths with suspicion, particularly where there is a second death in the family. Boys appear to be at a slightly higher risk.

In around half of cases, a cause of death cannot be found at the post mortem, and they are registered as having died of Sudden Infant Death Syndrome (SIDS).

It is still the most common cause of death in young babies.

Cot death kills more babies each year than road accidents, leukaemia and meningitis put together. But very little is known about what causes healthy babies to die so suddenly. However, the number of babies dying as a result of cot deaths in the UK has fallen by nearly 70 % since the introduction of initiatives to cut risk factors in the early 90s.

The campaign to encourage parents to put their babies to sleep on their backs is credited with significantly cutting deaths.

However, certain risk factors mean a baby is at a higher risk of cot death than if they are not present.

If the mother is under 27 and has more than one previous child, and if both parents are unemployed and are smokers, the likelihood of a cot death is around one in 200.

If none of these factors apply, then the likelihood is far less, around one in 8,5001.

The Foundation for the Study of Infant Death (FSID) advises that parents can reduce the risk of cot death by:

  • stopping smoking;

  • not letting anyone smoke near the baby;

  • placing the baby on its back to sleep;

  • not letting the baby get too hot;

  • keeping the baby's head uncovered;

  • keeping the baby in their bedroom for the first six months;

  • not sharing the bed with your baby if either parent smokes, has been drinking or takes medication or drugs which make them feel drowsy or tired;

  • not sleeping with the baby on the sofa;

  • seeking medical advice promptly if the baby appears to be unwell.
