1. Describe the structure of a capillary network

The capillary network is the vascular network specialized for movement of substances between blood and tissue.

Explanation:

The walls of the capillaries are thin and allow the substance to easily diffuse and pass through the substance. They are thinner than arteries and veins because their walls are made up of single layer of endothelial cells the flat blood cells.

The structure of vein consist of three layers. The outer layer is called tunica adventitia is a connective tissue, The middle layer of a smooth muscle is called tunica media, and the inner layer lined with endothelial cells are called tunica intima.

The main functions of the capillary is they bring nutrients and oxygen to tissues and remove waste products. The continuous, fenestrated and sinusoidal are the three types of capillaries.

A capillary network is a local network that uses short-range radio-access technologies to provide local connectivity to things and devices.

Explanation:

Capillaries are tiny, approx 2.5 micrometers in radius. They are composed of multiple layers of cells namely: an inner layer (which is of endothelial cells) and an outer layer (that is of epithelial cells). They are very small then we can imagine. Even the red blood cells need to flow through them a single file. The capillary network is the field of the vascular region that is specially designed for the movement of elements from blood to tissue and tissue to blood.
