Ascending Aorta

The ascending aorta is the initial section of the aorta, arising from the left ventricle of the heart and carrying oxygenated blood to the body.

Thoracic Aorta

The section of the aorta that passes through the thorax, supplying blood to the chest wall and thoracic organs.

Cardiac Muscle Fibers

Cardiac muscle fibers are specialized muscle cells in the heart that contract rhythmically to pump blood throughout the body; they are striated and interconnected, facilitating coordinated heart contractions.

Intercalated Discs

Structures in cardiac muscle cells that facilitate the synchronized contraction of the heart by allowing the rapid passage of ions between cells.
