Cardiovascular System
The cardiovascular system, also known as the circulatory system, is a network of vessels, including arteries, veins, and capillaries, that transport blood throughout the body. The heart, a muscular organ, pumps blood through the vessels, delivering oxygen and nutrients to the body's tissues and removing waste products. The cardiovascular system also plays a crucial role in regulating body temperature, pH balance, and fluid balance. In the maritime context, the cardiovascular system is particularly important for sailors and other maritime workers, who may be exposed to extreme weather conditions and physical exertion that can put a strain on the heart and circulatory system.
