What are valves?
This is the site of gas exchange in the circulatory system.

This peptide, produced by endothelial cells, is known for its potent vasoconstrictive properties.
What is endothelin?
Substances pass through the capillary wall by these three processes.
What are diffusion, filtration, and osmosis?
Deep vein insufficiency can lead to this dangerous condition.
What is DVT – deep vein thrombosis?
The conduction system starts at this node, called the “pacemaker.”
