Heart Anatomy
This muscular organ pumps blood throughout the body.
What is the heart?
These vessels carry blood away from the heart.
What are arteries?
This type of circulation carries blood between the heart and lungs
What is pulmonary circulation?
These cells are responsible for carrying oxygen throughout the body.
What are red blood cells?
This is a common term for chest pain caused by reduced blood flow to the heart.
What is angina?
The two upper chambers of the heart are called these
What is the atria?
The smallest blood vessels, where exchange of gases and nutrients occurs, are called these.
What are capillaries?
This system returns excess tissue fluid to the bloodstream and helps protect against infection.
What is the lymphatic system?
This component of blood helps in clot formation and prevents bleeding.
What are platelets?
This condition occurs when the heart suddenly stops beating.
What is cardiac arrest?
This structure separates the left and right sides of the heart.
What is the septum?
This major vein returns deoxygenated blood from the body to the heart
What is the vena cava?
Oxygenated blood flows from the heart to body tissues through this type of circulation.
What is systemic circulation?
The fluid part of blood, making up about 55% of its volume.
What is plasma?
High blood pressure is also known by this medical term.
What is hypertension?
The left ventricle pumps blood into this largest artery of the body.
What is the aorta?
The largest artery in the body, it carries oxygenated blood from the heart to the rest of the body.
What is the aorta?
This circulation system supplies blood specifically to the heart muscle.
What is coronary circulation?
These white blood cells are the first responders to microbial infection in the bloodstream.
What are neutrophils?
This condition, also called a heart attack, happens when blood flow to the heart muscle is blocked.
What is a myocardial infarction?
This valve lies between the left atrium and left ventricle.
What is the mitral (or bicuspid) valve?
These blood vessels are the primary sites of nutrient and waste exchange in tissues.
What are capillaries?
The law stating that blood flow is directly proportional to pressure difference and inversely proportional to resistance.
What is Ohm’s law?
This protein in red blood cells binds to oxygen, allowing it to be transported in the blood.
What is hemoglobin?
This irregular heartbeat is often described as a “flutter” or “quiver” in the heart.
What is atrial fibrillation?
