• Heart
• Arteries
• Capillaries
• Veins

$\textsf{\textbf{\red{Types \: of \: blood \: vessel:-}}}$

There are three main types of blood vessels of the human circulatory system are –

➊ Arteries :-

• Arteries carry oxygen rich blood away from the heart to all of the body's tissues.
• They branch several times, becoming smaller and smaller as they carry blood farther from the blood and into organs.

➋ Capillaries :-

• These are small, thin blood vessels that connect the arteries and veins.
• Their thin walls allow oxygen, nutrients, carbon dioxide and other waste products to pass from cells.

➌ Veins :-

• These are blood vessels that take blood back to the heart.
• These blood contains less oxygen and rich in waste products that are to be excreted or removed from the body.
