Cardiovascular System
This artery delivers oxygenated blood to the heart muscle.
What is the coronary artery?
This structure is primarily responsible for gas exchange in the lungs.
What are the alveoli?
This structure stores urine before it is excreted.
What is the bladder?
This part of the brain controls voluntary movement and coordination.
What is the cerebellum?
This gland regulates the release of thyroid-stimulating hormone (TSH).
What is the pituitary gland?
This valve prevents blood from flowing back into the left atrium.
What is the mitral valve?
The majority of air filtration, warming, and humidification occurs here.
What is the nasal cavity?
Most nutrient absorption occurs in this part of the digestive system.
What is the small intestine?
Taste receptors are located in this structure.
What are taste buds?
This structure connects muscle to bone.
What is a tendon?
This is the natural pacemaker of the heart.
What is the sinoatrial (SA) node?
This substance reduces surface tension to prevent alveolar collapse.
What is surfactant?
This structure prevents the contents of the stomach from flowing back into the esophagus.
What is the cardiac sphincter?
The sympathetic nervous system is most responsible for this type of response.
What is the "fight or flight" response?
This hormone is secreted by the pancreas to lower blood sugar levels.
What is insulin?
This is the protein in red blood cells that binds with oxygen.
What is hemoglobin?
This is the primary function of hemoglobin in the blood.
What is carrying oxygen from the lungs to tissues?
The nephron is primarily responsible for this function.
What is filtering blood and forming urine?
This structure is responsible for hearing.
What is the cochlea?
This is the most movable joint type in the body.
What is a synovial joint?
These white blood cells are primarily involved in responding to bacterial infections.
What are neutrophils?
This muscle contracts and flattens to help expand the lungs during inhalation.
What is the diaphragm?
This enzyme is secreted by the stomach to aid in protein digestion.
What is pepsin?
This part of the brain processes visual information.
What is the occipital lobe?
This gland is responsible for the "fight or flight" response by releasing adrenaline.
What are the adrenal glands?
