Answer 1

Answer:

The   circulatory  system is the main transport system of the human body. it is made up of the heart, blood, and blood vessels namely arteries ,  veins And  capillaries .These vessels bring oxygen-rich blood also Called veins   to the different tissues in the body and transport blood   from the tissues to the lungs ,in a process called circulation  

Explanation:

ABOUT CIRCULATORY SYSTEM -: Blood vessels that carry blood away from and into the heart make up the circulatory system. Blood is carried away from the heart by arteries, and blood is carried back to the heart by veins. Oxygen, nutrients, and hormones are carried to cells by the circulatory system and waste materials, such as carbon dioxide, are extracted.

THREE MAIN BLOOD VESSELS -:

• ARTERIES -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. The aorta, the large artery leaving the heart, begins with the arteries. They carry blood rich in oxygen away from the heart to all the tissues of the body. As they carry blood further from the heart, they branch several times, becoming smaller and smaller.
• VEINS -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. These are vessels of the blood that carry back oxygen-poor blood to the heart.  When they get closer to the heart, the veins get bigger and bigger. The superior vena cava is a large vein which carries blood from the head and arms into the heart, and the inferior vena cava carries blood from the abdomen and legs into the heart.
• CAPILLARIES -: Capillaries are small, thin blood vessels that connect the arteries and the veins.  Their thin walls allow the passage of oxygen, nutrients , carbon dioxide and waste products from and to the tissue cells.

BLOOD -: Blood circulates through the entire body through a network of vessels to provide oxygen and nutrients to individual cells and helps to dispose of metabolic waste. The blood around the blood vessels pumps the heart. Blood and circulatory processes circulate oxygen and extract carbon dioxide.
