01
The heart
A muscular pump with four chambers that moves blood to the lungs and the rest of the body.

Student learning pathway
Heart failure anatomy map: from the heart to symptoms, tests, and treatment.
Use this visual pathway to connect normal heart function with the concepts clinicians use to describe heart failure. It is built for retrieval practice—follow the links, then test what you remember in CollegeWard.
02
Cardiac output
The amount of blood the heart pumps matters because tissues depend on oxygen-rich circulation.
03
Heart failure
The heart cannot keep up with the body’s need for blood and oxygen; it does not mean the heart has stopped.
04
Symptoms
Fatigue and shortness of breath can appear as the weakened pump struggles with its workload.
05
Diagnosis → care
History, examination, tests such as echocardiography, and clinician-directed treatment complete the loop.
What to remember
Turn the map into a five-question drill.
When revising, recall the chain in both directions:
- Structure → function: chambers and muscle create the pumping action that supports circulation.
- Function → finding: reduced pumping ability can be reflected in symptoms and in measurements such as ejection fraction.
- Finding → next step: diagnosis and management depend on the person, the type of heart failure, and its severity.
