System & Vessels
This major body system is responsible for circulating blood, oxygen, and nutrients throughout the entire body.
What is the circulatory system?
Blood is made up of this exact number of primary components.
What is 4?
Along with blood vessels, this muscular organ is the other main part of the circulatory system.
What is the heart?
This chamber is the very first stop for oxygen-poor blood returning from the body to the heart.
What is the right atrium?
This fatty buildup inside arteries can cause them to narrow and eventually become clogged.
What is plaque?
This is the total number of distinct types of blood vessels found in the human body.
What is 3?
Making up 55 percent of blood, this yellowish liquid component holds blood cells in suspension.
What is plasma?
The human heart is divided into this total number of internal chambers.
What is 4?
This final heart chamber pumps oxygen-rich blood into the aorta so it can reach the rest of the body.
What is the left ventricle?
This cardiovascular disease is commonly referred to as the "silent killer" because it often shows no symptoms.
What is high blood pressure?
These blood vessels are responsible for carrying oxygen-rich blood away from the heart to the rest of the body.
What are arteries?
These biconcave disk-shaped cells are primarily responsible for transporting oxygen throughout the body.
What are Red Blood Cells (RBC)?
These are the specific names given to the top two receiving chambers of the heart.
What are the atriums?
After leaving the right atrium, deoxygenated blood moves directly into this lower chamber.
What is the right ventricle?
Poor diet, stress, genetics, and lack of exercise are the four primary causes of this medical condition.
What is high blood pressure?
These blood vessels carry oxygen-poor or deoxygenated blood back toward the heart.
What are veins?
Often called the "soldiers" of the body, these blood components help fight off infections and foreign bacteria.
What are White Blood Cells (WBC)?
These are the specific names given to the bottom two pumping chambers of the heart.
What are the ventricles?
After returning from the lungs, oxygenated blood first enters this specific chamber of the heart.
What is the left atrium?
Patients experiencing a heart attack frequently describe their chest pain using this famous phrase.
What is "I feel like there is an elephant on my chest"?
These microscopic blood vessels are the site where the actual exchange of oxygen, nutrients, and waste products occurs.
What are capillaries?
These cellular fragments act as clotting agents to help stop bleeding when you get a small cut.
What are platelets?
This large main artery connects directly to the left ventricle to distribute oxygenated blood to the body.
What is the aorta?
Blood leaves the right ventricle and travels to these organs, where oxygen-poor blood becomes oxygen-rich.
What are the lungs?
This dangerous medical event occurs when an artery supplying blood to the heart muscle gets clogged completely.
What is a heart attack?
