Circulatory System
The circulatory system is a complex network responsible for transporting blood throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps oxygen-rich blood from the lungs to the rest of the body, supplying organs and tissues with vital nutrients and oxygen. Blood vessels carry this blood, while veins return oxygen-poor blood to the heart for reoxygenation. This system is crucial for maintaining overall health, regulating temperature, and defending against disease, ensuring that every part of the body functions effectively.

The circulatory system is a complex network that transports blood throughout the body. It consists mainly of the heart, blood vessels, and blood. The heart pumps oxygen-rich blood from the lungs to the rest of the body, providing nutrients and oxygen to cells. Blood returns to the heart carrying carbon dioxide and waste products, which are then expelled from the body. This system helps maintain body temperature, transports hormones, and supports the immune system, ensuring that all organs function effectively and work in harmony to sustain life.

The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood. Its primary function is to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps oxygen-rich blood through arteries to the organs and tissues, while veins return oxygen-poor blood back to the heart. This system plays a vital role in maintaining body temperature, pH balance, and overall health. In essence, the circulatory system ensures that every part of the body receives the necessary substances it needs to function properly.
