FAQs on The Circulatory System – Chapter 7, Biology(Class 10)
1. What are the two types of circulatory system mentioned in The Circulatory System Solutions for Class 10 Science ICSE Board (Concise - Selina Publishers)?
Circulatory is broadly divided into two types. They are the closed circulatory system and the open circulatory system. The open circulatory system is mainly found in invertebrates e.g. in organisms like snails, cockroaches and spiders. Here, the body fluid flows directly in the cavities or open spaces called sinuses and lacunae. Thus, in this type of circulatory system blood vessels are not required for the process of circulation of blood. The second type of circulatory system is the closed one in which the heart (blood-pumping organ) pumps blood into the blood vessels (arteries & veins) which reaches the other tissues and organs. This type of circulatory system is mainly found in mammals including humans as well as in squids and earthworms.
2. What is the meaning of systemic and pulmonary according to The Circulatory System Solutions for Class 10 Science ICSE Board (Concise - Selina Publishers)?
We know that there are two types of circulatory systems (open and closed) that function differently using different constituents. You must remember that the closed circulatory system is present in humans. The process of circulation in humans occurs in two different pathways i.e. the systemic or the pulmonary. In the systemic circulation, the blood is received from all parts of the body whereas in pulmonary circulation, the blood is sent to other parts of the body and deoxygenated blood is received from the lungs for the process of oxygenation.
3. According to The Circulatory System Solutions for Class 10 Science ICSE Board (Concise - Selina Publishers), how are the oxygenated blood and deoxygenated blood in humans not mixed?
The human heart is divided by 4 chambers – it has two atria and two ventricles. The deoxygenated blood from the body is received by the right atrium and is pumped to the right ventricle which is pumped to the lungs for oxygenation. Now, the blood is oxygenated i.e. it has become rich in oxygen. This is now received by the left atrium and is sent to the left ventricle. The left ventricle then pumps this blood to the entire body. These one-way valves are the reason why the oxygenated and deoxygenated blood are not mixed and there is no backflow of the blood either.
