Difference between arteries and veins Figure 37-5 The Three Types of Blood Vessels Difference between arteries and veins Section 37-1 Artery Vein Connective tissue Smooth muscle Endothelium Valve Venule Arteriole Capillary Arteries – except for the pulmonary arteries, all arteries carry oxygen-rich blood. -thick walls that maintains pressure with muscle Veins contain valves that prevent the backward flow of blood. Veins tend to be superficial and arteries tend to be deep Capillaries are one cell thick so that diffusion occurs readily.

Blood is made up of red blood cells and many types of white blood cells Blood is the only fluid tissue in the body. Blood transports oxygen and nutrients to body tissues, and returns waste and carbon dioxide. Blood distributes nearly everything that is carried from one area in the body to another place within the body. For instance, hormones are transported from the endocrine organs to their target organs. Blood helps maintain body temperature and normal pH levels in body tissues. The protective functions of blood include clot formation and the prevention of infection.

Production of blood cells formation of blood cells All the various types of blood cells Link to a diagram showing the actual appearance of these cells (96K) are produced in the bone marrow (some 1011 of them each day in an adult human!). arise from a single type of cell called a hematopoietic stem cell — an "adult" multipotent stem cell

The lymph system's primary function is to isolate infection and cellular detritus from the rest of the body. The lymph system transports lymph fluid through ever-widening vessels, moving it through 500 filtration and collection points - your lymph nodes. Because lymph cleanses nearly every cell in your body, symptoms of chronic lymph blockage are diverse but can include worsened allergies and food sensitivities, frequent cold and flu infections, joint pain, headaches and migraines, menstrual cramps, arthritis, fibrocystic breasts, breast tenderness, sinusitis, loss of appetite and GI issues, muscle cramping, tissue swelling, fatigue, mental fuzziness, mood irregularities, depression, parasites, skin breakouts, acne, and cellulite. In general, you may feel tired and toxic, with a heaviness in your abdomen.
