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.
