Answer 2

Answer:Correct, most invertebrates do not have a capillary system. However, some exceptions include crustaceans, cephalopods, insects, and gastropods which have a specialized circulatory system.

Explanation:

Circulatory system is an essential means of transporting materials like respiratory gases, nutrients, hormones, intermediate metabolic products and metabolic end prod­ucts, to and from all body tissues, even those that are remote from the source of supply.

In invertebrates, the circulatory system is a network of channels and spaces in the con­nective tissue, which is continuous around and between all epithelial layers of the body. Invertebrate blood or haemal channels range widely in size.

Small tubular channels are called vessels; large sac like spaces are sinu­ses; small spaces are lacunae; and in case where the connective tissue compartment enlarges to form a voluminous, blood filled cavity, is called haemocoel.

Blood vessels that pass through mesenteries and septa are overlain -by mesothelium, which is often composed of myocytes bearing circularly arranged fibres. When the myocytes are dis­tributed widely over the surface of a blood vessel, their rhythmic contraction produces peristalsis, which pushes the blood forward in waves.
