The circulatory system

delivers oxygen and nutrients to cells and takes away wastes

. The heart pumps oxygenated and deoxygenated blood

What is circulatory system parts and functions?

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. 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

.

What are the 4 functions of the circulatory system?

  • To transport nutrients, gases and waste products around the body.
  • To protect the body from infection and blood loss.
  • To help the body maintain a constant body temperature (‘thermoregulation’)
  • To help maintain fluid balance within the body.

What is the function of the circulatory system definition?

Listen to pronunciation. (SER-kyoo-lah-tor-ee SIS-tem) The system that

contains the heart and the blood vessels and moves blood throughout the body

. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.

What are the five main 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.

What is the main organ of the circulatory system?


The heart

is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.

What are the 3 major parts of circulatory system and its function?

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.

Why is it called the circulatory system?

As the name implies,

blood contained in the circulatory system is pumped by the heart around a closed circle or circuit of vessels as it passes again and again through the various “circulations” of the body

.

What are the three parts of the circulatory system?

The Circulatory System moves nutrients to the cells of the body to feed them and help them fight disease. The main parts of the Circulatory System are

the heart, blood and blood vessels

. Arteries carry blood and the oxygen in it from the lungs to all of the other cells of the body.

What are the components of the circulatory system?

  • the heart.
  • blood vessels.
  • blood.

What is circulatory system in simple words?

Circulatory system:

The system that moves blood throughout the body

. The circulatory system is composed of the heart, arteries, capillaries, and veins. This remarkable system transports oxygenated blood from the lungs and heart throughout the body via the arteries.

What the two major components of blood are?

  • Plasma, which is a clear extracellular fluid.
  • Formed elements, which are made up of the blood cells and platelets.

How are the organs of the circulatory system protected?

Protection: The cardiovascular system protects the

body through its white blood cells

. White blood cells clean up cellular debris and fight pathogens that have entered the body.

What are the 5 functions of the heart?

  • Pumping oxygenated blood to the other body parts.
  • Pumping hormones and other vital substances to different parts of the body.
  • Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
  • Maintaining blood pressure.

What’s the main artery called?

The largest artery is

the aorta

, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
