Series synopsis
left|thumb|upright=1.25|Title card|alt= The title card of Grey Anatomy
Grey's Anatomy chronicles the lives of surgical interns, residents, and attendings at the fictional Grey Sloan Memorial Hospital (formerly Seattle Grace Hospital, Season 1–6; Seattle Grace Mercy West Hospital, Season 6–9; and then Grey Sloan Memorial Hospital, Season 9–present), as the interns progressively evolve into seasoned doctors under the guidance of their residents, attendings, and the chief of surgery.
Each episode usually opens with a voice-over narration from Meredith Grey or another season regular, often foreshadowing the episode's theme. Most seasons typically mirror the physicians' academic year, with each completed year elevating the residents to a higher level in the surgical field. The season finale often culminates in a dramatic event, such as a character's death or departure.
The series focuses on the doctors' professional lives as surgeons, but also gives significant attention to their personal lives.
Upon arrival at the hospital each morning, residents may compete over who gets assigned a challenging case, often generating tension. A hospital superior typically assigns cases, further intensifying the dynamic between residents and their superiors. Episodes shift between the doctors' interactions with patients and their personal dynamics with colleagues. Once assigned a case, each doctor works to diagnose the patient, typically with the support of an attending physician, which usually results in surgery. Each episode typically features scenes of a surgery towards the center of the episode.
The show often portrays the doctors forming personal connections with their patients, with many cases indirectly reflecting the doctors' own personal struggles. One notable instance is Izzie Stevens' entanglement with her patient, Denny Duquette, in Season 2. Relationships between the doctors, whether romantic or platonic, frequently develop and create conflicts between their personal and professional lives.
Emotional moments are often underscored by an indie rock soundtrack, with "songtages" – tracks that run through a montage of scenes, connecting storylines with poignant lyrics – becoming a hallmark of the series. Each episode concludes with a voice-over, generally providing contrast or a follow-up to the initial narration. They are initially mentored by Dr. Miranda Bailey, a senior resident who becomes the hospital's Chief Resident, and later an attending general surgeon, in Season 6. The surgical program is initially headed by Richard Webber, the Chief of Surgery, who has a pre-existing personal relationship with Meredith, having had an affair with her mother, famed general surgeon Ellis Grey, when Meredith was a child.

Shepherd is introduced as Meredith's love-interest, while Burke begins a relationship with Cristina.
Introduced in the show's second season are obstetrician-gynecologist and neonatal surgeon, Addison Montgomery, plastic and ENT surgeon Mark Sloan (nicknamed 'McSteamy' by the interns), from New York, and orthopedic surgeon Callie Torres. Montgomery is Shepherd's estranged wife who arrives in Seattle seeking reconciliation with him, Sloan is Shepherd's former best friend, who aided the breakdown of his marriage by having an affair with Montgomery, while Torres is introduced as a love-interest, and eventual wife for O'Malley. The penultimate episode of Season 3 introduces Lexie Grey, Meredith's half-sister who unexpectedly decides to pursue her internship at Seattle Grace Hospital after her mother's sudden death, and begins an on-again, off-again relationship with Sloan. Burke and Yang, having been engaged, endeavor to plan their wedding, while Montgomery departs the show in the Season 3 finale, relocating to California, seeking a new life, thus becoming the lead character of the spin-off Private Practice. The Season 3 finale also shows Burke's exit from the show, after leaving Yang at the altar on their wedding day.
