Option A: Cockroaches have an open circulatory system and are also known as the lacunar circulatory system. In this case, the blood falls into the cavity of the body and does not circulate in the blood vessels, so it flows at low pressure. Therefore, this is an incorrect option.
What is the problem with the circulatory system?
Common problems with the circulatory system include: Aneurysm – Weakness of the arterial wall. Atherosclerosis – Arterial stenosis caused by plaque deposition. Heart disease-Insufficient blood supply to the heart due to narrowing of the arteries.
Are cockroaches closing the circulatory system?
The insect cockroach has an open circulatory system.
Why is the cockroach circulatory system open?
This is because cockroaches are in the category of arthropods, which are primitive organisms. Cockroaches do not depend on the heart or blood for the transport of oxygen in the body. They have fully developed the tracheal network for the above process.
What is right about the cockroach heart?
Cockroaches have a tubular heart with 13 chambers. Oxygenated blood enters each chamber through a pair of slit-like slits known as Ostia. The first chamber leads to the aorta, which in turn leads to the cranial sinus. Therefore, the correct option is option d.
