Arteries

100

What is the average heartbeat of the heart?

60 - 100 beats per minutes

100

How many valves does the heart have? 

Four! The Tricuspid valve, Pulmonary valve, Mitral valve, and Aortic valve

100

What the main function of the Circulatory system?

The circulatory system delivers oxygen and nutrients to cells and takes away wastes.

100

Is blood blue?

False


200
What are the tubes that carry blood to the heart?

Veins

200

How many red blood cells do we lose per second?

We lose 3 million red blood cells each second

200

What is it called when plaque builds upon the walls of your arteries

Atherosclerosis


200

What are the three main parts of the Circulatory system?

blood, blood vessels, and heart

200

Nutrients are transported to all cells in the body through blood vessels

True

300

What are blood vessels that connect arteries and veins together?

Capillaries
300

How much blood does our heart pump each heartbeat?

The heart bumps 2 ounces of blood each beat, five quarts of blood each minute, or 220 million quarts in 70 years

300

If blood is coming from the Right Atrium what type of blood is it.

Deoxygenated blood

300

How does the Circulatory system interact with the Endocrine system?

The circulatory system delivers hormones to the body which help regulate your body's processes, like hunger, blood pressure, and sexual desire.

300

Without oxygen, blood cells can still function properly 

False

400

What are platelets?

Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels

400

If you were to put the whole Circulatory system outside the human body and lay it out how long would it be?

66 million miles or more than two and half times the circumference of the earth

400

How does a heart attack happen?

When a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.

400

How does your Respiratory system rely on your Circulatory system?

The Circulatory system delivers the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. 

400

500

Name the four-chamber of the heart

YES! but it's extremely unlikely. Emotional or traumatic events can lead to a surge of stress hormone which can put you into short-term heart failure. 

500

Please explain the pathway the deoxygenated blood travels to be oxygenated

Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta

500

Name the two loops/circuits that occur at the heart

Pulmonary circuit and Systemic circuit

500

Platelets help clot damaged blood vessels until they are fully repaired

True
