The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in
Also to know is, what are the 5 functions of the circulatory system?
Functions of the cardiovascular system
- Circulates OXYGEN and removes Carbon Dioxide.
- Provides cells with NUTRIENTS.
- Removes the waste products of metabolism to the excretory organs for disposal.
- Protects the body against disease and infection.
- Clotting stops bleeding after injury.
Also, what are the 4 main functions of the circulatory system? Major Functions of the Cardiovascular System. On this page we take a closer look at the four major functions of the cardiovascualr system – transportation, protection, fluid balance and thermoregulation.
Similarly, you may ask, what does the Circulatory System Transport?
Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
What does the circulatory system consist of give the main function of each?
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.

What is the main function of blood?
Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body. Nutrients from the digestive tract and storage sites to the rest of the body.
What is the function of human heart?
Human Heart: Anatomy, Function & Facts. The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. “The tissues of the body need a constant supply of nutrition in order to be active,” said Dr.
Is blood a tissue or an organ?
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
What are the two types of circulation?
There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation. Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
How does the circulatory system transport nutrients?
Transporting nutrients to the cells of your body is the job of your circulatory system. Nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins. Nutrients, oxygen and wastes all pass in and out of your blood through the capillary walls.
What is open circulatory system?
Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
