Summary Introduction

To discuss:

The organization of a capillary bed and how its perfusion is regulated.

Introduction:

Capillaries are known as the business ends or exchange vessels of the cardiovascular system. The passage of nutrients, hormones, leukocytes, and waste, through the walls of the blood vessels into tissue, can occur through capillaries and venules. Capillaries only have a basal lamina and an endothelium. Based on their function, the capillaries are classified into three types, namely continuous capillaries, fenestrated capillaries, and sinusoid capillaries.
