The smallest part of the circulatory system is the capillary. Capillaries are tiny, thin blood vessels that allow for the exchange of oxygen, nutrients, and waste products between the blood and tissues in the body.

Which body system does the aorta belong?

The aorta belongs to the circulatory system. It is the largest artery in the human body, responsible for carrying oxygen-rich blood from the heart to the rest of the body.


Is there a spleen in the circulatory system?

Ok, I have no idea what you mean by that question. Technically, since blood flows to the spleen to keep it alive...then yes. But blood flows to every living cell in your body to keep it alive so...yeah. But is the spleen a part of the circulatory system? That is also a yes. It is part of the lymphatic system, not the cardiovascular system. The lymphatic system is a sub-system of the circulatory system that basically helps fight infection, recycle blood plasma, etc. Most people do not think of the lymphatic system as part of the circulatory system though (even though it is) and most use the words "circulatory" and "cardiovascular" interchangeably (even though they're not interchangeable). Seeing as the cardiovascular organs are the heart and blood vessels, if that is what you meant...then no it's not. Please be more specific with your questions.

What system transports materials to and from the body's cells?

The circulatory system, which includes the heart, blood vessels, and blood, transports materials such as oxygen, nutrients, and waste products to and from the body's cells. Oxygen and nutrients are delivered to cells, and waste products are carried away from cells for removal by the circulatory system.


Open circulatory system to lymphatics to closed circulatory system is to blood circulatory system?

The transition from an open circulatory system to a lymphatic system involves the movement of fluid and immune cells through vessels and lymph nodes. This ultimately connects to the closed circulatory system, responsible for transporting oxygen, nutrients, and waste products through the body. The closed circulatory system, also known as the blood circulatory system, uses the heart to pump blood through arteries, capillaries, and veins to maintain circulation.
