A total of 26 were killed in the attack on a Piccadilly line train between King's Cross and Russell Square
The coroner at the 7/7 inquests has praised the courage and professionalism of a doctor who was the first medic on the scene of the Edgware Road attack.
Dr Elizabeth Wynne-Evans told the inquests she rushed into the bombed Tube to help the wounded despite having only a rudimentary first aid kit.
Earlier, the inquests heard tributes from relatives of those killed in another of the Tube attacks.
Fifty-two people were killed by suicide bombers on three Tubes and a bus.
Dr Wynne-Evans told the hearing at the Royal Courts of Justice in central London that she was waiting for a bus outside Edgware Road station when she saw people in various states of distress, covered in soot, emerging from the exit.
She said she poured water onto one woman's burned and blistered face to soothe it before heading down to the bombed carriage.
"What I can recall is there being glass everywhere, a very prominent acrid smell - the smell of burning flesh - and some sort of blood, debris and glass everywhere," she said.
She examined a number of casualties - many already dead, the court heard. She said she found one man holding his briefcase with the back of his clothing blown away.
With the injured, she was able to check wounds and stayed with the more serious cases until further help and medical equipment arrived.
Coroner Lady Justice Hallett told Dr Wynne-Evans: "You were down there as quickly as you could, helping people. You acted with great courage and great professionalism."
Earlier on Monday, relatives of those killed in the attack on a Piccadilly line train between London King's Cross and Russell Square spoke of their loss.
Shelley Mather's mother Kathryn Gilkison said the 26-year-old was "a kind, generous, friendly, bright and amazing young woman" who wanted to "circumnavigate the universe".
Speaking about what her future might have been, she added: "That could have been anything she had wanted it to be."
Veronica Cassidy, whose 22-year-old son Ciaran was another of the victims, told the inquests: "He had no hate in him or ego and he didn't care for politics or war.
"He loved his family, friends and Arsenal."
Lives cut short
Stacey Beer remembered her brother, Philip, 22: "Phil was never able to fulfil his dreams and ambitions - he was so young and barely an adult when he was killed.
"Phil's ambition was to become a well-known hairdresser and travel the world."
Germaine Lindsay killed 26 people when he detonated his bomb
Samantha Badham, 35, and Lee Harris, 30, had been together for 14 years when they were both killed in the Piccadilly line attack.
Mr Harris' mother, Lynne, told the inquests she had "lost a son and daughter on July 7 together with the hopes of seeing them grow old together and have children".
Liz Staffell told the inquests that unlike most gap-year students, her daughter Helen Jones had spent her time working with prostitutes and drug addicts at Glasgow's city mission.
She added: "Into a busy life Helen had packed more living, more loving and more giving than many of us will have in a very long life."
Harry Levy said his wife Susan, 53, had been "a wonderful woman and someone people felt they had known for years even though they only just met her".
Ernest and Elaine Adams' tribute to their son, James, 32, was read by a lawyer.
They said he had been a committed Christian and charity worker, so well thought of that one of the charities he supported in southern India had erected a building in his memory.
