The circulatory system consists of blood arteries that transport blood away from and toward the heart. Arteries convey blood out from the heart, whereas veins return it. The circulatory system transports oxygen, nutrients, and hormones to cells while also eliminating waste products such as carbon dioxide. These roadways are one-way only, ensuring that transport flows in the proper direction. The purpose of this group is to provide information on the different tissues present in our circulatory system.

Under the microscope, a mammal vein reveals a quiet kind of beauty. Its thin, flexible walls and smooth lining show a graceful design meant for steady, low-pressure blood flow. You can often see red blood cells gently passing through, like tiny messengers on a peaceful journey. Functionally, veins are essential, they carry blood back to the heart, working with valves to keep everything flowing in the right direction, even against gravity. It’s a gentle but vital part of the circulatory system.
The mammalian vein sample under LPO highlights the relatively thin wall and wide lumen characteristic of veins, as compared to arteries. This slide is useful for identifying the structural adaptations of veins that facilitate their function in low-pressure blood return
