Elastic-muscular layer
How does the endocardium of the atrium compare to the endocardium of the ventricle?
Endocardium of the atrium contains more connective tissue than endocardium of the ventricle
What is the main component of microvascular capillaries?
Endothelial cells
Which type of capillaries has a complete endothelial lining with tight junctions?
Continuous capillaries
Test your knowledge about the smallest blood vessels, thin tubes formed by a single layer of highly permeable endothelial cells. Explore how they facilitate the transfer of O2, CO2, substrates, and metabolites between the blood and tissues. Learn about the different types such as continuous capillary, fenestrated capillary, and sinusoid capillary.
