As a medical professional with a background in anatomy and physiology, I can provide an explanation for why veins may become more prominent or "pop out" under certain conditions.
Veins are the blood vessels that return deoxygenated blood back to the heart. They are composed of three layers: the inner layer (intima), the middle layer (media), and the outer layer (adventitia). The middle layer is where you'll find the most elastic and muscular tissues, which allow veins to expand and contract as blood flows through them.
There are several reasons why veins might become more visible:
1. Physical Activity: During exercise, the heart pumps more blood to supply the body with oxygen and nutrients. This increased blood flow can cause veins to dilate, making them more visible, especially in the arms and legs.
2. Hydration: Dehydration can cause the skin to shrink, which can make veins more prominent as there is less fluid in the tissues surrounding the veins.
3. Age: As people age, the skin becomes thinner and loses elasticity, making veins more visible.
4. Sun Exposure: Prolonged exposure to the sun can damage the skin and reduce its thickness, which can also contribute to the visibility of veins.
5. Varicose Veins: These are swollen, twisted veins that can be seen just under the surface of the skin. They are often blue or dark purple and can be caused by various factors, including genetics, pregnancy, obesity, and prolonged standing.
6. Blood Volume: An increase in blood volume, such as during pregnancy, can also cause veins to become more prominent.
7.
Skin Color and Thickness: Individuals with lighter skin or thinner skin may naturally have more visible veins.
8.
Muscle Relaxation: When the muscles in the arms or legs are relaxed, the veins can become more prominent as there is less compression from the surrounding muscle tissue.
9.
Medical Conditions: Certain medical conditions can also cause veins to become more visible, such as venous insufficiency or heart failure.
It's important to note that while visible veins are often a normal part of anatomy, if they are accompanied by pain, swelling, or other symptoms, it's advisable to consult a healthcare professional.

This process, known as filtration, causes a swelling and hardening of the muscle that is noticed during exercise. As a result of this swelling, cutaneous veins are pushed toward the skin surface, flatten to some extent, and appear to bulge. Such veins are more visible in persons with less subcutaneous fat.
