Human Biology Unit 2 Quiz

The lymphatic system consumes pathogens, produces antibodies, and helps neutralize toxins released by pathogens.

The lymphatic system transports a clear watery fluid called lymph, which contains white blood cells, cellular debris, and bacteria.

During blood clotting, platelets form a plug at the injury site, and plasma components known as coagulation factors create fibrin strands to strengthen this plug.

A complex system that plays a key role in immunity, fluid balance, and waste removal.

A clear fluid that circulates throughout the lymphatic system, containing white blood cells, cellular debris, and bacteria.

Specialized white blood cells produced by the lymphatic system that destroy pathogens and produce antibodies.

Proteins produced by the lymphatic system that specifically target and neutralize pathogens.

Substances produced by pathogens that can harm the body.

The two upper chambers of the heart that receive blood from the body and lungs.

The two lower chambers of the heart that pump blood to the lungs and the body.

The circulation of blood from the heart to the lungs and back.

The circulation of blood from the heart to the rest of the body and back.

Blood that is low in oxygen and high in carbon dioxide.

The valve between the left atrium and the left ventricle.

The valve between the right atrium and the right ventricle.

The valves that prevent backflow from the aorta and pulmonary artery into the ventricles.

Chord-like tendons that prevent the valves from turning inside out.

Thicker muscular walls of the ventricles allow them to generate more force to pump blood.

The heart's right side pumps deoxygenated blood to the lungs, while the left side receives oxygenated blood from the lungs and pumps it throughout the body.

The superior vena cava carries deoxygenated blood from the upper body to the right atrium of the heart.

The inferior vena cava carries deoxygenated blood from the lower body to the right atrium of the heart.

The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs.
