Your doctor may tell you to mix your insulin lispro solution with another type of insulin (NPH insulin) in the same syringe. Your doctor will tell you exactly how to do this. Always draw insulin lispro into the syringe first, always use the same brand of syringe, and always inject the insulin immediately after mixing.
The main function of blood vessels is to carry blood through the body. The blood carries oxygen, nutrients, and wastes that need to move around the body. There are three kinds of blood vessels: arteries, veins, and capillaries.
The systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart. The system of blood vessels in the human body measure about 60,000 miles (96,560 kilometers). Arteries carry oxygen-rich blood from the heart through the body. Veins carry oxygen-poor blood back to the heart. The superior vena cava carries oxygen-poor blood into the heart.
