The eyelid has the thinnest skin compared to the earlobe and the lip. This is because the skin on the eyelid is delicate and sensitive, allowing for easy movement and flexibility of the eyelid. The thinness of the skin in this area also helps to protect and cover the sensitive structures of the eye, such as the cornea and the conjunctiva.

The term "magnetic resonance" refers to the process of using magnetic fields and radio waves to create images based on the behavior of atoms in the body.

Frederick Banting and his colleagues discovered the hormone insulin in the 1920's. This breakthrough discovery revolutionized the treatment of diabetes and saved countless lives. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. Banting's work led to the development of insulin therapy, which allowed people with diabetes to manage their condition effectively. The discovery of insulin in the 1920's marked a major milestone in medical history and has had a profound impact on the lives of millions of people worldwide.

Explanation
The human heart beats approximately 100,000 times per day. This is because the heart is responsible for pumping blood throughout the body, supplying oxygen and nutrients to the organs and tissues. The average resting heart rate is around 60-100 beats per minute, which adds up to approximately 100,000 beats in a 24-hour period. However, heart rate can vary depending on factors such as physical activity, stress, and overall health.

Explanation
The aorta is the largest artery in the body. It is responsible for carrying oxygenated blood from the heart to the rest of the body. It is a thick and elastic artery that branches out into smaller arteries, delivering blood to various organs and tissues. The aorta plays a crucial role in maintaining blood flow and distributing nutrients and oxygen throughout the body.
