The correct answer is option 'D' - Anterior aorta.
Explanation:
In a cockroach, the heart consists of a tubular structure divided into chambers. The first chamber is called the alary heart, and it pumps deoxygenated blood towards the anterior part of the body. The blood vessel that arises from the first chamber of the heart in a cockroach is called the anterior aorta.
The anterior aorta is the main artery that carries oxygenated blood to the different parts of the body. It branches out into smaller vessels called arteries, which further divide into arterioles and capillaries, allowing the exchange of gases and nutrients with the tissues.
The structure and function of the cockroach's circulatory system are similar to other insects. The heart pumps hemolymph, which is a fluid equivalent to blood in vertebrates. The hemolymph flows through a series of interconnected tubes called tracheae, which deliver oxygen directly to the tissues.
The anterior aorta is responsible for supplying oxygenated hemolymph to the head and anterior regions of the cockroach's body. It ensures the delivery of nutrients and oxygen for cellular respiration and metabolic processes.
In summary, the blood vessel that arises from the first chamber of the heart in a cockroach is the anterior aorta. It plays a crucial role in delivering oxygenated hemolymph to the head and anterior parts of the body, providing nutrients and oxygen for vital physiological functions.

The circulatory system of the cockroach is placed in the pericardial sinus. The circulatory system of cockroach consists of a tubular heart, which is 13 chambered. A blood vessel called as the anterior aorta arises from the first chamber of the heart.
Each chamber of the heart receives oxygenated blood from the dorsal sinus through one pair of slit-like openings called as ostia.
Fenestrae is one of two perforations, covered with the membrane on the head of a cockroach.
The nephrocyte in a cockroach is the lateral wall of their heart. This wall helps excretion and helps store waste.
