MT 30-E Lab (Histology Art 2024-2025) 7 months ago The circulatory system, also known as the cardiovascular system, is responsible for transporting blood, nutrients, oxygen, carbon dioxide, hormones, and other essential substances throughout the body. It plays a vital role in maintaining homeostasis, supporting cellular function, and protecting the body from disease. The main components of the circulatory system are the heart, blood vessels, and blood. The heart acts as a muscular pump that continuously propels blood through the body. Blood vessels include arteries, which carry oxygen-rich blood away from the heart; veins, which return oxygen-poor blood back to the heart; and capillaries, which are tiny vessels where the exchange of gases, nutrients, and waste products occurs between the blood and tissues. Blood itself is made up of red blood cells, white blood cells, platelets, and plasma. The circulatory system is essential not only for delivering oxygen and nutrients to tissues but also for removing waste products, regulating body temperature, and distributing immune cells to fight infections. It works closely with other systems, such as the respiratory system for gas exchange and the digestive system for nutrient absorption, to ensure the proper functioning of the body.
