Explanation (Approx. 300 words):
The circulatory system plays a critical role in maintaining life by transporting essential substances throughout the body. Each term listed above represents a key part of this system.
An artery is a blood vessel that carries oxygenated blood away from the heart to various tissues, with the exception of the pulmonary artery which carries deoxygenated blood to the lungs. Blood, composed of red cells, white cells, platelets, and plasma, serves as the medium for transport of gases, nutrients, and waste products.
Capillaries are tiny blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues. These structures connect arteries and veins, forming an extensive network throughout the body.
Oxygen is a vital gas carried by red blood cells from the lungs to body tissues. Cells require oxygen for aerobic respiration, a process that generates energy. In return, carbon dioxide is transported back to the lungs for exhalation.
The septum is a muscular wall dividing the right and left sides of the heart, ensuring that oxygen-rich and oxygen-poor blood remain separate for efficient circulation.
A vein is a blood vessel that carries blood toward the heart. Most veins carry deoxygenated blood, except for pulmonary veins which return oxygenated blood from the lungs.
The heart functions as a powerful pump that drives blood through the arteries and veins in a continuous loop. Each heartbeat ensures movement of blood through this closed system.
A valve ensures unidirectional blood flow in the heart and veins by preventing backflow. Valves are essential for maintaining efficient circulation, especially in the low-pressure venous system.
This set of components together supports a fully functional circulatory system.
