What is calcium?
This mineral is necessary for the formation of healthy bones and teeth.
What are salivary glands?
These glands produce saliva, which contains enzymes that begin the digestion of carbohydrates.
What is the aorta?
This largest artery in the human body carries oxygenated blood away from the heart
What is the right ventricle?
This chamber of the heart pumps oxygen-poor blood to the lungs for oxygenation.
Dietary Guidelines: What is 5 to 9 servings?
How many servings of fruits and vegetables are recommended per day according to dietary guidelines?
What is vitamin C?
This vitamin, found in citrus fruits and leafy greens, is essential for collagen synthesis and wound healing.
What is the esophagus?
This is the muscular tube that connects the throat to the stomach.
What is the inferior vena cava?
What is the largest vein in the human body, which carries deoxygenated blood to the heart?
What is the mitral valve (or bicuspid valve)?
This valve separates the left atrium from the left ventricle and prevents the backflow of blood into the atrium.
What is the percentage of a nutrient in one serving compared to the recommended daily intake?
What does the %DV (% Daily Value) on a food label represent?
What is potassium?
This mineral is crucial for muscle contraction, nerve function, and maintaining normal blood pressure.
What is the liver?
This digestive organ secretes bile, which emulsifies fats for better digestion.
What is the left atrium?
This chamber of the heart receives oxygen-rich blood from the lungs.
What is the bundle of His?
This part of the heart's conduction system conducts electrical impulses between the atria and ventricles.
What is the inferior vena cava?
Blood returning from the lower body enters the heart through this large vein
What can a lack of vitamin C do?

What are villi?
These finger-like projections in the small intestine increase its surface area for nutrient absorption.
What are arteries?
These blood vessels carry blood away from the heart to various parts of the body.
What are Purkinje fibers?
These specialized muscle fibers in the heart transmit electrical signals, causing the heart to contract rhythmically.
What are coronary arteries?
These blood vessels supply oxygenated blood to the muscles of the heart
What is vitamin D?
This vitamin, found in dairy products and fortified foods, is essential for calcium absorption and bone health.
What is ghrelin?
This hormone, released by the stomach, stimulates the secretion of gastric juices and increases hunger.
What are capillaries?
These thin-walled blood vessels facilitate the exchange of nutrients and waste products between the blood and tissues
What are the sinoatrial (SA) node and atrioventricular (AV) node?
These structures, also known as the "pacemaker" of the heart, regulate the heart's rhythm.
What is the pulmonary artery?
This blood vessel carries deoxygenated blood from the heart to the lungs for oxygenation.
