innermost layer; squamous epithelium surrounded by connective tissue with elastic fibers
middle layer of artery; made up of smooth muscle fibers and thick layer of elastic connective tissue
largest type of artery; contains many elastic fibers that allow it to stretch in response to each pulse; close to the heart.
arteries that deliver blood; active in vasoconstriction; thick tunica media. Distribute to all parrts of the body.
This system's funtions are (1) to transport tissue fluid to the blood vessels, and (2) to protect the body by removing foreign material such as bacteria from the lymphatic stream and by serving as a cite for lymphocytes "policing of body fluids and lymphocyte multiplication. It is a one-way system that carries lymph only towards the heart.
smooth muscle cells from a continuous layer. addition of tunica adventiatia made of collagenous connective tissue
capillaries found in skin and muscles; uninterupted lining; held with tight junctions
secretions enter the circulation through these that contain open spaces between their epithelial cells. Pores, holes
Are like fenestrated capillaries but they have gaps between adjacent endothelial cells and thin or absent basal lamina.
leaky capillaries; found only in the liver, bone marrow, lymphoid tissues and some endocrine glands; allow large molecules to pass between blood and surrounding tissues
When two arteries merge and provide alternative routes of blood supply to a tissue:
what are vascular anastomoses especially with veins that provide alternative pathways for blood to reach a given body region
allow arteries to have direct connections w/ veins and bypass the capillary bed when needed
condition in which fatty deposits called plaque build up on the inner walls of the arteries
the blood pressure (as measured by a sphygmomanometer) during the contraction of the left ventricle of the heart
the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood
