FAQs on Cockroach: Circulatory System Video Lecture - Biology Class 11 - NEET
| 1. What is the circulatory system of a cockroach? |  |
Ans. The circulatory system of a cockroach is an open circulatory system, which means that the blood, called hemolymph, is not enclosed within blood vessels. Instead, the hemolymph flows freely within the body cavity, directly bathing the organs and tissues.
| 2. How does the circulatory system of a cockroach work? | |
Ans. In the circulatory system of a cockroach, the heart pumps hemolymph into the aorta, which then divides into smaller arteries. The arteries carry the hemolymph to various organs and tissues. After supplying the oxygen and nutrients, the hemolymph flows back into the heart through ostia, which are openings in the heart.
| 3. What is the role of the circulatory system in a cockroach? | |
Ans. The circulatory system in a cockroach plays several important roles. It transports oxygen and nutrients to the cells, removes waste products, distributes hormones, and helps in regulating body temperature. It also plays a role in the defense mechanism against foreign substances and pathogens.
| 4. Can cockroaches survive without a circulatory system? | |
Ans. No, cockroaches cannot survive without a circulatory system. The circulatory system is essential for the transportation of oxygen, nutrients, and waste products throughout the body. Without it, the cells would not receive the necessary oxygen and nutrients, leading to organ failure and death.
| 5. How does the circulatory system of a cockroach differ from that of a human? | |
Ans. The circulatory system of a cockroach differs from that of a human in several ways. Cockroaches have an open circulatory system, while humans have a closed circulatory system. Cockroaches have a tubular heart, whereas humans have a four-chambered heart. Additionally, cockroaches do not have specialized blood vessels like arteries and veins, as the hemolymph flows freely within their body cavity.
