Tubular heart of cockroach has how many chambers

Heart of cockroach is elongated, tubular and pulsatile organ which is composed of narrow anterior aorta and thirteen segmentally arranged funnel shaped chambers , perforated by Ostia. Conical alary muscles that are twelve pairs in number are attached to the dorsal diaphragm which causes straightening of the heart and causes circulation of the. Blood vessels in cockroaches are poorly developed and they open up into space known as hemocoel. The heart of the cockroach consists of an elongated muscular tube lying along the dorsal line of the thorax and abdomen. It is transformed into funnel-shaped chambers with Ostia. The cockroach has a 13 chambered tubular heart. Hence, Option 2 is. The heart of a cockroach is an elongated tubular structure, closed behind and open in front.

Valves, ensuring the unidirectional flow of blood, guard the passage of each heart chamber

Heart of Cockroach: The heart or dorsal blood pericardial sinus. It consists of thirteen contractile chambers. The first three are present in the tho­racic segments, while the remain­ing ten chambers are placed in the abdominal segments. The first chamber of the heart forms a single narrow tubular anterior aorta leading into the head sinuses There is a tubular heart enclosed in a pericardial sinus, and lying in the mid-dorsal line immediately beneath the terga of the thorax and abdomen. It is composed of thirteen chambers each of which communicates with the pericardial sinus by a pair of ostia T he heart of the cockroach is elongated, thick, muscular, tubular and 13-chambered.

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest 49. (d) Digestive system of cockroach is divided into -foregut, midgut and hindgut. The mouth opens into a short tubular pharynx which further opens into a narrow tubular structure called oesophagus. The oesophagus opens into a sac-like structure called crop where food is stored. The crop is followed by gizzard and proventriculus. The gizzard.

Circulatory System Parts. The circulatory system consists of the heart, blood, blood vessels, lymph, and lymphatic vessels. While the heart is the largest organ of the circulatory system, it is really only a large blood vessel surrounded by muscles.The arteries and veins themselves are sometimes considered together as an interconnected organ that spans through the body These insects' functional organism is characterized by a tubular dorsal heart, which gives life to the insect. Even the heart of spiders can generate beats that range between 30 and 100 beats per minute. In this way, through the tracheal tubes, this organ captures oxygen and other compounds necessary to beat and give life to the insect
