A cauterizer or stitch.
Connective tissue flows through the heart and blood vessels.
because vascular tissue is a blood vessel
Epithelial tissue lacks blood vessels. Instead, it receives nutrients and oxygen through diffusion from nearby blood vessels in the underlying connective tissue.
Laser surgery is used to: Cut or destroy tissue that is abnormal or diseased without harming healthy, normal tissue; Shrink or destroy tumors and lesions; Cauterize (seal) blood vessels to prevent excessive bleeding.
Tissue fluid is returned to circulation through the lymphatic system, where it is collected in lymph capillaries and transported back to the bloodstream through lymphatic vessels.
capillaries
Vascular just means that the tissue has a blood supply, in other words, it has blood vessels running through it. Avascular means that the particular tissue does not have blood vessels in it. For example, the cornea of the eye is avascular. This is one of the reasons it's an 'easy' transplant... because it doesn't bleed!
Connective tissue obtains nutrients through diffusion from nearby blood vessels. Nutrients diffuse through the blood vessel walls and into the surrounding connective tissue to provide nourishment to the cells within the tissue.
It is the thin lining that goes through the outer surface of blood vessels and cavities.
Simple squamous epithelial tissue does not have a good blood supply because it is a thin layer of cells that is designed for diffusion and filtration rather than for supporting blood vessels. Instead, nutrients and oxygen are supplied through diffusion from nearby blood vessels.
Blood vessels are surrounded by very small circular muscles which contract and relax to allow blood vessels to constrict and dilate. The vessels also contain elastin which allows them to stretch.
Sugar and nutrients are carried up through the phloem vessels.
