Hint: The human heart is a muscular organ that is involved in the pumping of the blood. The blood is transported to different body parts through three types of blood vessels such as arteries, veins and capillaries.
Complete step by step answer: The correct answer is:
‘A' is the vena cava that carries deoxygenated blood. The vena cava brings deoxygenated blood from all the tissues of the body to the right atrium of the heart. The blood then passes the right ventricle via a valve. The blood is then pumped to the lungs for oxygenation.
'B' is the aorta that carries oxygenated blood. It carries oxygen-rich blood to all the tissues and organs of the body. The aorta receives blood from the left ventricle after it is oxygenated in the lungs.
'C' is the pulmonary artery that carries deoxygenated blood. It is also known as pulmonary circulation. The pulmonary artery carries deoxygenated blood from the left ventricle to the lungs.
'D' is the pulmonary vein that carries oxygenated blood. It is also a part of the pulmonary circulation, where the blood that is oxygenated in the lungs via diffusion and is brought to the left atrium.
Additional information: Blood enters the heart through two large veins; the posterior and the anterior vena cava which carries deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve. There are three main types of blood vessels involved in the circulation process; arteries, veins and capillaries.
Note: The blood contains a protein called haemoglobin, which is involved in the transportation process. It is a biconcave structure present in the red blood cells that carry oxygen as well as carbon dioxide.
