Regardless of the vein size, blood can still be drawn. I personally have smaller and weaker veins, and can still donate, but sometimes it takes a few tries.

Why Do Leaves Have Veins? This pattern is made up of much larger, primary veins that connect to the leaf stem as well as smaller, secondary veins. The larger veins' main purpose is to carry water from the stem into the leaf, while the smaller veins spread it throughout every part of the leaf. The smaller network of veins also collects chlorophyll created in the leaf, which the larger veins then transport back to the main part of the plant. Each species of plant has a unique pattern of veins in its leaves, varying in the density of the network and the distance between the larger veins. Some scientists have begun studying exactly what this pattern says about a plant and have made a number of conclusions.

- Varicose veins are visible veins in the leg that bulge, often protruding through the skin. They are the result of venous insufficiency: blood that pools in the vein because of a faulty valve and causes the protrusion. Varicose veins are a symptom of early stage venous disease. Untreated, they can lead to increased symptoms and worsening appearance. Varicose veins affect approximately half of the U.S. population, and in addition to causing pain and discomfort, those with varicose veins struggle unnecessarily with their appearance.

Some people may progress from having no symptoms, to the development of varicose veins, and then on to problems with leg swelling, and finally to ulcers caused by stagnant blood flow. A small number of these people will have deep vein clots as a cause for their signs and symptoms, but most will not.

Superficial phlebitis is most often caused by an intravenous catheter (IV) placed in a vein, and the vein becomes irritated. Superficial phlebitis may or not have a blood clot form to cause the pain and inflammation. In the legs, superficial phlebitis can be associated with varicose veins. Causes of deep vein thrombosis or thrombophlebitis include: 1  inactivity (blood pools in the veins and tends to clot if a person is inactive for a prolonged period of time); 2  trauma, and.  blood clotting abnormalities (may be inherited).
