About this document
Capillary Function and Blood Flow Dynamics by jchu2919 is a document available to read on EtoBox.
- Capillaries open and close depending on tissue activity, with about 3/4 closed at any given time to regulate blood flow and exchange. Exchange occurs between tissues and nearby blood vessels. - Veins have weaker walls than arteries and collapse when empty, taking irregular shapes. They have one-way valves to prevent backflow of blood. - The heart receives a disproportionate and increased blood supply from the coronary arteries during diastole when the aortic valve is open, to ensure adequate oxygenation
