Fundamentals of Human Biology Quiz

The heart pumps blood throughout the body to deliver oxygen and nutrients to tissues and organs.

The respiratory system transports oxygen from the air into the bloodstream and removes carbon dioxide.

The nervous system processes and transmits information through electrical and chemical signals.

Fibroblasts are not components of blood; rather, they are cells found in connective tissue.

The kidneys filter waste products from the blood and regulate fluid balance.

The gallbladder stores bile produced by the liver and releases it into the small intestine to aid in digestion.

The skeletal system supports the body, protects organs, and produces blood cells, but it does not produce digestive enzymes.

Respiration is the process where cells break down glucose using oxygen to produce energy.

White blood cells defend the body against infections and foreign invaders.

Cartilage is not a type of muscle tissue; it is a type of connective tissue.

Peripheral ganglia are part of the peripheral nervous system, not the central nervous system.

The lymphatic system helps the body fight infections and maintains fluid balance.

The pancreas produces insulin, a hormone that regulates blood sugar levels.

The adrenal glands produce adrenaline, which helps the body respond to stress.

Insulin regulates blood glucose levels by facilitating the uptake of glucose into cells.

Melatonin regulates the sleep-wake cycle and is produced by the pineal gland.
