Enrol is the standard spelling in British English, which breaks the general rule that British words carry with them an extra consonant. In many cases, such as traveling-travelling, canceled-cancelled, totaled-totalled, labeled-labelled, etc., it is the British spelling that contains the two –ll’s.

But, in the case of enrolment, the standard spelling in British English only has one l – enrol and yet in past tense it is – enrolled.

in American English the word has two ll’s – enroll and enrolled.

The origin of the word

The word enroll originated from late Middle English (formerly also as inroll ): from Old French enroller, from en- ‘in’ + rolle ‘a roll’ (names being originally written on a roll of parchment).

We were talking about feeding babies, and when the practise of using a pump to express milk originated.

The first patent for a breast pump was filed in 1854 by Orwell Needham in New York. The pump was made of a rubber cup connected to a glass pipe in which there was a hole. A mother would control the vacuum effect with her finger. A flexible tube connected the glass pipe back to a bellows fitted in a box.

The goal was to mimic the sensation of a nursing baby.

Atropos is cutting the threads
Sandie Shaw is a puppet on a string
And still
That still small voice that whispers
You should know that
Seek and ye shall find,
is a warning?

Gallstones are dried and compacted lumps of bile that form in the gallbladder when bile builds up. Gallstones can be as small as a grain of sand or the size of a golf ball. They do not cause symptoms in most people.

A train in Ireland: Ireland has some beautiful railways, and with recent cuts to fares, train travel there is now remarkably affordable. If you only have time for one trip, hop aboard at Rosslare, the ferry port at the country’s southeastern tip, and travel up the east coast to Dublin, says Vic O’Sullivan in The Guardian.

The journey of two to three hours is among the loveliest in Europe. The line wends at first across the Sloblands, marshy plains that are a winter sanctuary for migratory birds, to Wexford Town. Next comes the “striking” Norman town of Enniscorthy, and then Arklow, beyond which the scenery is “positively Alpine”, the train climbing higher and higher before plunging into the “lush” Vale of Avoca. Past Wicklow Town, there are ever more dramatic coastal views on the way to Bray, where it’s worth switching to the DART commuter service to visit “idyllic” seaside towns such as Dalkey and Killiney on the way into Dublin. Tickets cost from €7.49 (irishrail.ie).

In this description, oxygen-rich blood means blood filled with oxygen, and oxygen-poor blood means blood lacking oxygen.

The heart is divided into four chambers. The upper chamber of the right side of the heart – that is the right as one can imagine looking down on one’s own heart – is known as the right atrium and it receives oxygen-poor blood from the body. The blood travels to the lower right chamber – the right ventricle – and when the heart beats, the blood is squeezed into the lungs, where it is reloaded with oxygen and carries on its way up to the upper left chamber of the heart..

When the heart relaxes, the oxygen-rich blood flows into the upper left chamber – the left atrium – of the heart. From there is moves down into the left ventricle and when the heart beats the oxygen-rich blood is pumped to the organs throughout the body, including to the muscle of the heart itself because it too needs oxygen-rich blood to keep functioning.
