You are studying the mechanisms underlying human heart development, in the hope of uncovering novel therapies aimed at re-building heart tissue in those that have suffered damage (e.g. cases of heart attack). For this reason, you are working with a variety of different bio-engineered hearts.
You are organising the heart mutant protypes in your research notebook: Match the mutant with the phenotypes that directly arise from the mutation in combination with the normal phenotypes present because of the mutation. More than one answer may apply.
CV.mut.3: probe-patent foramen ovale
This transverse histological image is an example of what type of blood vessel?
This low magnification histological section shows two different blood vessel types for comparison. At this level, corresponding blood vessels can often be found in close proximity to one another.
What blood vessel type is labelled 'A'?
This is a high magnification histological section.
What type of blood vessel is labelled 'A'? What type of blood vessel is labelled 'B'?

Atria & Auricles
The atria have out-pouches called auricles (= 'ears'). These are visible mostly from the anterior view of the heart. Internally, the auricles of the atria contain mostly pectinate muscle.
