INSECT MORPHOLOGY - CIRCULATORY SYSTEM 1 * Insects have an open blood system with the blood occupying the general body cavity which is thus known as a haemocoel.Blood is circulated mainly by the activity of a contractile longitudinal vessel (called the dorsal vessel) which opens into the haemocoel and which usually lies in a dorsal pericardial sinus, cut off by a Blood. Open circulatory systems (and their slower rate of blood flow) are usually associated with animals that have relatively low metabolic needs. The Heart, Blood Vessels, Blood Types The Closed Circulatory System •Humans have a closed circulatory system, typical of all vertebrates, in which blood is confined to vessels and is distinct from the interstitial fluid. List and add 2 additional traits you can add to each branch of the phylogeny. Illustration of a grasshopper with open circulatory system In an open circulatory system, the hemolymph surrounds all internal . the ground. Circulatory System. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment such as proper temperature and pH known as homeostasis. Instead of flow occurring in a closed system of tubes and produced by a large central pump, the insect system is open, consisting of a single, open-ended tube (the heart and aorta) that runs dorsally from the abdomen to the thorax or head [ 18 ]. Circulatory system The circulatory system is an open one, with most of the body fluid, or hemolymph, occupying cavities of the body and its appendages.
