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 heart and into organs.
Capillaries. These are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste products to pass to and from cells.
Veins. These are blood vessels that take blood back to the heart; this blood contains less oxygen and is rich in waste products that are to be excreted or removed from the body. Veins become larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
Any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange are called alveoli.

<h3>What is CPR?</h3>
CPR stands for Cardio-pulmonary resuscitation. It may be defined as a lifesaving procedure that's valuable in many troubles, such as a heart attack or near drowning, in which an individual's breathing or heartbeat has stopped.
The best way to perform CPR is to kneel subsequent to the person and position the heel of your hand on the breastbone at the center of their chest.
Position the palm of your other hand on top of the hand that's on their chest and interlock your fingers. Place yourself so your shoulders are straight above your hands.
Therefore, it is well described above.
