Blood
These tiny donut-cough drop shaped components give blood their red color. Sickle cell anemia occurs when these are the wrong shape.
What are red blood cells?
This major blood vessel at the top of the heart is the largest artery in the body and is the main gateway for the blood to go from the heart into the body.
What is the aorta?
This is the broad term for the tubes that blood flows through in the body.
What are blood vessels?
This is the name for the substance that can build up in the circulatory system by sticking to the walls of your blood vessels. It sounds like something you would find on your teeth.
What is plaque?
The blood is responsible for carrying this gas to all parts of the body. When it has delivered all of this gas so the body can produce energy, it returns back to the heart.
What is oxygen?
The pulmonary veins bring oxygenated blood back from the lungs, and flow directly into this quadrant of the heart.
What is the left atrium?
These are used in the circulatory system to primarily carry oxygenated blood from the heart to the body's extremities.
What are arteries?
Blood circulation helps the body with this process which involves regulating things like temperature and electrolytes.
What is homeostasis?
This is the central wall of the heart, dividing it into left and right sides.
What is the septum?
These are used in the circulatory system to primarily carry deoxygenated blood from the body back to the heart.
What are veins?
This issue is caused when a cranial artery is blocked or burst which hinders the blood flow to the brain, causing that part of the brain to die.
What is a stroke?
When flowing through the arteries, blood appears to be this color due to the oxidized iron.
What is bright red?
This quadrant of the heart pumps the blood to the blood through the pulmonary circuit.
What is the right ventricle?
These are the smallest blood vessels that can get to only one cell in diameter. They are used for gas and nutrient exchange when the arteries are flowing into the veins.
What are capillaries?
What is a heart attack?
This feature of the blood is incredibly important when a blood vessel is cut or broken. It allows for the hole to be patched up and not let all the blood flow out until it can heal.
What is clotting?
This quadrant of the heart pumps blood into the aorta, and out to the rest of the body. It typically has the thickest and most muscular walls to perform this task.
What is the left ventricle?
These are present in the veins and are used to ensure that the blood flows against gravity in the right direction toward the heart.
What are valves?
This circulatory issue occurs when a blood vessel blows up like a balloon and can potentially burst. If this occurs in a major blood vessel, it can be lethal.
What is an aneurysm?
