The respiratory system is responsible for delivering sufficient oxygen to all cells of the body and for removing carbon dioxide (CO 2) that is produced as a waste product of cellular respiration. Given the high level of activity in many arthropods (such as honeybees), consider how the presence of the tracheal system enables these animals to fulfill their high metabolic demand. The heart is a bit like the engine, making sure the blood can get to where it needs to go. In an open system, blood (usually called hemolymph) spends much of its time flowing … Mucus - from cells lining the mouth; it makes food easier to swallow. • Efferent (motor) neurons-- unipolar cells that conduct signals AWAY from CNs and stimulate responses in muscles and glands.

Introduction to Circulatory System in Earthworm: Earthworms possess a closed circulatory system in which blood always flows in the vessels and never comes in direct contact with tissues. Q. After filling out the order form, you fill in the sign up details. Hemocyanins are copper-containing respiratory pigments found in many mollusks (some bivalves, many gastropods, and cephalopods) and arthropods (many crustaceans, some arachnids, and the horseshoe crab, Limulus).They are colourless when deoxygenated but turn blue on oxygenation. The heart. the dorsal vessel is divided into two regions: a posterior … Human circulation consists of a closed circulatory system. The heart, blood vessels and blood make up the circulatory system – because together, they keep blood circulating. Like other insects, the ladybug has an exoskeleton made of a protein like the one that forms our hair and fingernails. Read the following features of vessels :- (a) It carries blood from organ to heart (b) Blood flows with high pressure & speed yo (c) Their lumen is constricted (d) The walls of vessels are thin & soft (e) They usually collapse when empty — (f) Valves are generally absent (g)They arrange superficially just below the skin. #4- Circulatory System Materials: preserved fetal pig, dissecting pan, scissors, forceps, blunt probe, twine/string, safety goggles, one pair of disposable latex gloves per dissection day, tape measure.

They are vermiform (worm like) animals with a body divided into a series of similar segments or somites. Circulatory system: Insects do not have blood, or blood vessels that are part of a closed circulatory system. The food then pass into the gizzard where it is ground & shredded & is pushed into the midgut In the midgut, enzymes are released to digest the food & nutrients are absorbed Undigested matter enters the hindgut & leaves the body The Grasshopper: Circulatory system Nutrients are transported through the body of a grasshopper by an open circulatory system Hemolymph … 1.
