What are the 7 functions of the circulatory system?

What are the 7 functions of the circulatory system?

Functions of blood and circulation:

• 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.

How does the circulatory system of the heart work?

The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

Where does the blood go when it leaves the circulatory system?

As the blood reaches the capillaries of the different organs of the body, oxygen, food, and other substances diffuse out of the blood and into the tissues. At the same time, waste materials from the cells diffuse into the bloodstream. The blood returns to the heart by way of veins.

How does the circulatory system work like a tree?

The arteries carry blood away from the heart; the veins carry it back to the heart. The system of blood vessels resembles a tree: The “trunk” – the main artery (aorta) – branches into large arteries, which lead to smaller and smaller vessels. The smallest arteries end in a network of tiny vessels known as the capillary network.

Is there only one circulatory system in the human body?

There is not only one blood circulatory system in the human body, but two, which are connected: The systemic circulation provides organs, tissues and cells with blood so that they get oxygen and other vital substances. The pulmonary circulation is where the fresh oxygen we breathe in enters the blood.

What are the three functions of the circulatory system?

• The circulatory system delivers nutrients and oxygen to different cells of the body.
• It carries body metabolic waste away
• It protects the body from diseases as it serves as the body’s defence system

  How does the circulatory system do its job?

  The circulatory system consists of your heart, blood, and blood vessels. Its main job is to carry oxygen throughout the body to the cells and to carry waste products from the cells out of the body.

  What is the job of the circulatory system?

  What is the job of the Circulatory System? The Circulatory Systemis responsible for transporting materials throughout the entire body . It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce.

  How does the circulatory connect with any other systems?

  The circulatory system is connected to many other systems. One of them is the respiratory system . The kidneys filter the blood and then sends it back to the heart in a vein called the vena cava. The digestive system is the last connection to the circulatory system.
