Heart Anatomy
The names of chambers in the heart.
What are atria and ventricles?
In humans, blood normally flows in this many directions.
What is one direction?
This is one of the two major arteries that leave the heart. This one carries blood to the body.
What is the aorta?
These are the flexible, bagel-shaped cells that carry oxygen throughout your body.
What are red blood cells?
The name of fluid that runs through the lymphatic system.
What is lymph?
The heart is mostly made up of this type of tissue.
What is muscle?
This part of the circulatory system pumps blood going to and leaving from the lungs.
These are the smallest blood vessels, where exchange of fluid and substances between blood and cells takes place.
What are the capillaries?
This is the part of the blood that transports proteins, sugars, and other chemicals in your blood.
What is plasma?
This is the main function of the lymphatic system.
What is collecting lost fluid from around your cells?
The name for the wall that separates the right side of the heart from the left side of the heart.
This is what makes the "lub-dub" sound your doctors hear when they listen to your heart.
What is the valves closing?
This is the thicker of the two types of blood vessels because it contains a lot of muscle.
What are arteries?
These are cell fragments that float around in your blood and aid in clotting.
What are platelets?
This is where lymph is returned to the circulatory system.
What are large veins in the chest?
This valve separates the left atrium from the left ventricle.
What is the bicuspid/mitral valve.
This is the part of your heart that coordinates the contraction of the muscle fibers.
What is the pacemaker?
This is the name of the large vein that empties into the heart located above the heart.
What is the superior vena cava?
This is the protein that gives red blood cells their color and carries oxygen within the cells.
What is hemoglobin?
These help prevent lymph from flowing backwards through lymphatic vessels.
What are valves?
The side of the heart contains deoxygenated blood (blood that has little oxygen in it).
What is the right side?
This buildup of fat in arteries can cause high blood pressure and, if severe enough, lead to a heart attack.
What is arteriosclerosis?
This is the tissue that makes up the outer portion of blood vessels and gives them flexibility and support.
What is connective tissue?
These proteins act as "name tags" on your red blood cells and determine your blood type.
What are antigens?
These lumps of tissue help filter out things that can make you sick.
What are lymph nodes?
