Amino acids
The building blocks of proteins.
Aorta
The largest artery in the body, carrying oxygenated blood from the left ventricle to the rest of the body.
Arteries
Blood vessels that carry blood away from the heart.
Atria
The two upper chambers of the heart that receive blood.
Atrioventricular node (AV node)
A part of the heart's electrical conduction system that delays the electrical signal from the atria to the ventricles.
Atrioventricular valves
Valves located between the atria and ventricles that prevent backflow of blood.
Capillaries
Tiny blood vessels that connect arteries and veins, where exchange of nutrients and gases occurs.
Diastole
The phase of the cardiac cycle when the heart muscle relaxes and the chambers fill with blood.
Digestive organs & accessory organs
Organs involved in digestion, including the mouth, esophagus, stomach, intestines, liver, pancreas, and gallbladder.
Fatty acids
The building blocks of lipids (fats).
Monosaccharides
Simple sugars that are the building blocks of carbohydrates.
Myocardium
The muscular tissue of the heart.
Myogenic muscle
Muscle tissue that generates its own contractions (e.g., the heart muscle).
Oxygenated blood
Blood that is rich in oxygen.
Deoxygenated blood
Blood that has had much of its oxygen removed.
Pulmonary artery
The artery that carries deoxygenated blood from the right ventricle to the lungs.
Pulmonary vein
The vein that carries oxygenated blood from the lungs to the left atrium.
Purkinje fibres
Specialized muscle fibers that conduct electrical impulses through the ventricles, causing them to contract.
Respiratory organs
Organs involved in gas exchange, including the lungs, trachea, and bronchi.
Semilunar valves
Valves located at the exits of the ventricles (aortic and pulmonary valves) that prevent backflow of blood.
Septum
A wall that divides the heart into left and right sides.
Sinoatrial node (SA node)
The heart's natural pacemaker, which generates electrical impulses that initiate heartbeats.
Systole
The phase of the cardiac cycle when the heart muscle contracts and pumps blood out of the chambers.
Veins
Blood vessels that carry blood towards the heart.
Vena cava
The large vein that carries deoxygenated blood from the body to the right atrium.
Ventricles
The two lower chambers of the heart that pump blood out to the lungs or the rest of the body.
