fold‚ where the breast meets the chest. For about 5%[10] to 10%[17] women‚ their breasts are severely different‚ with the left breast being larger in 62% of cases.[17] This is due to the breast proximity to the heart and a greater number of arteries and veins‚ along with a protective layer of fat surrounding the heart located beneath it.[18] Up to 25% of women experience notable breast asymmetry of at least one cup size difference.[10][19][20][21] If a woman is uncomfortable with her breasts’ asymmetry

of coronary veins and arteries. The heart is the size of a clenched fist‚ located slightly to the left of the chest. It is divided into left and right sides‚ has four chambers and works as a pump. Veins deliver deoxygenated blood from the body to the right side of the heart; this is known as Pulmonary Circulation. The heart then pumps this back to the lungs to absorb oxygen. Oxygenated blood returns to the left side of the heart which pumps it to the rest of the body through the arteries; this is known

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

The foramen spinosum transmits the middle meningeal artery from the infratemporal fossa into the cranial cavity. The jugular foramen transmits the following structures from before backward: inferior petrosal sinus‚ CN IX‚ X‚ XI‚ and the large sigmoid sinus. The facial nerve exits the cranium via the stylomastoid
