Arteries act as conduits for blood, but this is not their only function; much of their specialized structure is dependent on the essential physiological role they have to play in the circulation. They develop under two sets of influences: genetic factors mainly control the morphological pattern of...

Compare and contrast the major structures and functions of invertebrates and vertebrates. Compare and contrast the anatomy and physiology of blood vessels: arteries, veins, and capillaries. Why are these differences significant in the overall function of the circulatory system?
Both direct in vitro evidence and histological evidence strongly suggest that in essential hypertensive patients there is an alteration in the structure of proximal resistance vessels (small arteries); the media: lumen ratio is increased and the lumen volume is decreased. Although it may be supposed...
Describe the structure and function of the arteries, veins, and capillaries. Name and describe the structure and function of three plant tissues. Explain about the structure and function of the pulmonary system. Explain how structure and function are correlated at all levels of the biological hierar...
The present invention relates to the unexpected finding that vessels smaller than even the smallest arteries (i.e. arterioles) thicken, become dysfunctional and cause end organ damage to tissues as diverse as the brain and the kidney. This invention provides a method to improve the structure and...
OBJECTIVE: To investigate the effects on resistance artery structure and function of monotherapy with the beta-blocker atenolol or the calcium channel antagonist nifedipine in its once a day form or gastrointestinal therapeutic system (GITS). SUBJECTS: Twenty well-controlled essential hypertensive patients...
5. What types of blood vessels are in the body?Discuss their structure and function.Blood vessels are of three types: arteries, capillaries,and veins.Arteries transport blood away from the heart. Theyhave think walls composed of an inner endothelium layer(tunica internal), an outer connective ti...
The atypical structure and function of newborn arterial endothelium is mediated by Rho/Rho kinase signaling Endothelium of fetal or newborn arteries is atypic S Flavahan,NA Flavahan - 《American Journal of Physiology》 被引量: 9发表: 2014年 Cytoskeleton, cytoskeletal interactions, and vascular endo...
Middle ear cavity expansion has occurred in members of all three groups, apparently in association with an essentially 'freely mobile' ossicular morphology and the development of bony tubes for the middle ear arteries. Cavity expansion can occur in different ways, resulting in different subcavity ...
