What is the circulatory system?
The term circulatory system describes both the cardiovascular system and the lymphatic system. Both work closely together to move fluids around your body and protect it from disease. Your moving blood helps to keep all parts of your body warm.
What is the cardiovascular system and what does it do?
Your heart, blood, and blood vessels make up your cardiovascular system, which transports blood around your body. The cardiovascular system is a closed circulatory system meaning that the blood is carried in vessels that form a closed loop.
Blood is the fluid that carries gases, nutrients, and wastes through the body. The blood maintains homeostasis by transporting hormones, nutrients, and oxygen to cells and by carrying wastes away from cells.
What is the lymphatic system?
The lymphatic system is a group of organs and tissues that collect lymph and return it to the blood. The lymphatic system is an open circulatory system and lymph can move in and out of the vessels. The lymphatic system is also part of the body's defenses against disease. Certain lymph vessels in the abdomen move from the intestine and into the blood.
What is lymph?
Lymph is the fluid that leaks from blood. Lymph capillaries absorb the lymph and bring it to larger lymph vessels. It is returned to the cardiovascular system when it drains into blood vessels at the base of the neck.
What are capillaries?
Capillaries are tiny blood vessels. Every time your heart pumps a little fluid is forced out of them. Most of the fluid is reabsorbed by the capillaries, and the remaining fluid is collected by lymph capillaries.
What are lymph capillaries?
Lymph capillaries absorb fluid, particles such as dead cells, and pathogens from around body cells. The lymph capillaries carry the lymph to larger lymph vessels.
