ICSE Class 5 Circulatory Systems Question Answers
Q – What are some of the vital organs in the body?
Lungs, kidneys, heart, and brain.
Q – What are organ systems?
Organ systems are groups of organs that work together to perform a particular function in the body.
Q – What are some important organ systems in the body?
Circulatory system, digestive system, nervous system, respiratory system, etc.
Q – What does the circulatory system do?
The circulatory system is responsible for transporting blood, nutrients, and oxygen to various parts of the body.
Q – What is the function of the digestive system?
The digestive system is responsible for breaking down food and absorbing nutrients from it.
Q – What is the role of the nervous system?
The nervous system is responsible for controlling and coordinating all the body’s functions and responding to internal and external stimuli.
Q – What is the respiratory system responsible for?
The respiratory system is responsible for the exchange of oxygen and carbon dioxide in the body.
Q – What is the largest organ in the human body?
The skin is the largest organ in the human body.
Q – What gives us energy to do different activities in our daily life?
The food that we eat gives us energy to do different activities.
Q – What do we need to breathe in besides food?
We need oxygen to breathe in besides food.
Q – Why is it important for nutrients and oxygen to reach various parts of the body?
Nutrients and oxygen are needed to provide energy and nourishment to various parts of the body for proper functioning.
Q – What are the waste products produced by our body?
Carbon dioxide, urine, and sweat are some of the waste products produced by our body.
Q – What is the name of the system responsible for transporting nutrients, oxygen, and waste products in the body?
The circulatory system is responsible for transporting nutrients, oxygen, and waste products in the body.
Q – What is the function of the circulatory system?
The circulatory system moves blood around the body to transport nutrients, oxygen, and waste products.
Q – What is transported by the blood in most animals?
In most animals, the blood transports food, water, and oxygen to cells in all parts of the body.
Q – What is the job of the circulatory system in removing waste products?
The circulatory system transports waste materials made in the body cells to different parts of the body for excretion.
Q – What does the circulatory system consist of?
The circulatory system consists of the heart, blood, and blood vessels.
Q – What is the function of the heart?
The heart pumps blood to all parts of the body through a network of tubes called blood vessels.
Q – Where is the heart located in the body?
The heart is located in the chest cavity slightly towards the left side.
Q – What is the size of the heart?
The size of the heart is roughly equal to our fist.
Q – What is the heart made of?
The heart is made of a special muscle called cardiac muscle.
Q – How many compartments are there inside the heart?
The hollow space inside the heart is divided into four compartments called chambers.
Q – What are the upper chambers of the heart called?
The upper chambers of the heart are called atria.
Q – What are the lower chambers of the heart called?
The lower chambers of the heart are called ventricles.
Q – What are the four chambers of the heart?
The four chambers of the heart are left atrium, right atrium, left ventricle, and right ventricle.
Q – What is the function of the atria?
The atria receive the blood.
Q – What is the function of the ventricles?
The ventricles pump the blood away from the heart.
Q – Why is blood red in color?
Blood is red in color because it contains a red pigment called hemoglobin.
Q – What are the functions of blood in the body?
Blood carries digested food and water, oxygen, and waste products from the body cells. It also protects the body from diseases.
Q – What does blood carry to different parts of the body?
Blood carries oxygen from the lungs to different parts of the body.
Q – What does blood carry from the body cells to the lungs?
Blood carries the waste product carbon dioxide from the body cells to the lungs for breathing out.
Q – What is the role of white blood cells in blood?
White blood cells kill bacteria and other germs which cause diseases, thus protecting the body from diseases.
Q – What are the three types of blood vessels?
The three types of blood vessels are arteries, veins, and capillaries.
Q – What is the function of arteries?
Arteries carry blood away from the heart to all parts of the body.
Q – Where are arteries located in the body?
Arteries are located quite deep under the skin and hence are not seen easily.
Q – Why do arteries have thick and elastic walls?
Arteries have thick and elastic walls because blood flows through them at high pressure.
Q – What type of blood do all arteries normally carry?
All arteries normally carry oxygenated or pure blood from the heart to all parts of the body.
Q – What is the main artery coming out of the heart?
The main artery coming out of the heart is the aorta.
Q – What is the function of the pulmonary artery?
The pulmonary artery carries deoxygenated or impure blood from the heart to the lungs.
Q – What are veins?
Veins are the blood vessels that carry blood from all parts of the body back to the heart.
Q – How are veins different from arteries in terms of location and visibility?
Veins are less deep than arteries and can be seen easily. The greenish-blue lines that we see just below the skin on our hands and legs are veins.
Q – What is the flow rate of blood in veins?
Blood flows at low pressure through the veins.
Q – Why do veins have thin walls and valves?
Veins have thin walls because they carry blood at low pressure. They also have valves which prevent blood from flowing backwards.
Q – What are the two important veins in the body and what is their function?
The two important veins are the superior vena cava, which brings blood from the upper part of the body to the heart, and the inferior vena cava, which brings blood from the lower part of the body to the heart.
Q – What type of blood do all veins normally carry?
All veins normally carry deoxygenated or impure blood from body organs, except for the pulmonary vein.
Q – What is the main difference between an artery and a vein?
The main difference between an artery and a vein is that an artery normally carries blood from the heart to the body organ, whereas veins normally carry blood from the body organs back to the heart.
Q – What are capillaries?
Capillaries are thin blood vessels that connect arteries to veins.
Q – Where are capillaries present in our body?
Capillaries are always present in between the arteries and veins in our body.
Q – What can pass through the thin walls of capillaries?
Nutrients, oxygen, carbon dioxide, and other waste materials can pass through the thin walls of capillaries.
