Just wanted to add another few thoughts to Grumpy's excellent comments.
Wound care - in the UK its the nurses domain. Doctors don't do wound care. You will be expected to know the different dressing categories and when to use them, and don't even think about trying that darned WTD gauze if you want to keep your licence! You will usually do plaster casting as well, although the bigger A&Es do have technicians for this during the daytime.
Suturing is usually a nursing role as well, although most A&Es will have protocols where certain wounds, (mostly facial) get referred on to Plastics for suturing. But the majority of A&E suturing is done by nurses.
And there are no respiratory therapists, you will set up your own CPAP and BiPAP, and work with the docs on RSIs.
As Grumpy mentioned, the 4 hour rule prevails and sets the pace. You will get into a rhythm, patients are triaged within 15 minutes, including labs and EKG, then seen by a doc within the hour. At 2 hours all results are in and they are reviewed. By 3 hours you should be getting a decision on discharge v admit, and they need to be gone by 4 hours.
There have been several A&E closures in recent years, which means that the ones that still exist have far higher census numbers. Its not unusual anymore for departments to see several hundred patients each day, when they might only have seen 200 a decade ago.
Nursing is a lot more 'hands-on' in the UK, and you will be changing diapers for incontinent patients, and helping to feed those that need it. Body fluid spills are cleaned up by nurses, and you will work as a team player, doing whatever is needed to keep the department moving. This might include pushing carts to xray, (they are called trolleys, btw) or emptying linen bags, or running to pharmacy. You work far more as a team, so when you coworker receives a new patient, you all dive in! One does the triage, another does the EKG and another does the labs, so that everything is done in the 15 minutes.
