Circulatory System
A system designed to transport food and other necessary substances throughout an organism’s body
The circulatory system, also known as the cardiovascular system, is responsible for transporting blood, oxygen, and nutrients to various parts of the body. It is made up of the heart, blood vessels, and blood.
The heart is a muscular organ that pumps blood throughout the body. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body.
Blood vessels are the pathways that allow blood to flow throughout the body. There are three types of blood vessels: arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart to the rest of the body. Veins carry deoxygenated blood back to the heart. Capillaries are small, thin vessels that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Blood is the fluid that circulates throughout the body. It is made up of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for carrying oxygen to the body’s tissues. White blood cells are part of the immune system and help fight off infections. Platelets are important for blood clotting to prevent excessive bleeding. Plasma is the liquid portion of blood that carries nutrients, hormones, and waste products.
Overall, the circulatory system plays a vital role in maintaining the health and homeostasis of the body by ensuring that all organs and tissues receive the necessary nutrients and oxygen and eliminate waste products.
