| What are the two divisions of the nervous system that work together to process and respond to stimuli? | The central nervous system and the peripheral nervous system. |
| The __________ nervous system controls involuntary actions like digestion, while the __________ nervous system controls voluntary actions like walking. | autonomic; somatic |
| What is the function of neurotransmitters in the nervous system? | They act as chemical messengers that transmit signals between neurons or from neurons to muscles and glands. |
| What are the names of the four chambers of the heart? | The left atrium, right atrium, left ventricle, and right ventricle. |
| The ____________ system transports lymph, filters pathogens, and supports immune function. | Lymphatic |

| The __________ system uses hormones to regulate body processes, while the __________ system uses nerve impulses. | endocrine; nervous |
| How do the respiratory and circulatory systems work together to maintain pH homeostasis? | The respiratory system regulates carbon dioxide levels in the blood, which directly affects blood pH, while the circulatory system distributes oxygen and removes carbon dioxide. |
| What is the primary function of the autonomic nervous system? | To regulate involuntary physiological processes such as heart rate, digestion, and respiratory rate. |
| Hormones are secreted into the bloodstream by the __________ system to regulate activities in distant tissues. | endocrine |
| What is the role of the immune system in the body? | To identify and neutralize pathogens such as bacteria, viruses, and other harmful organisms. |
| What structural feature ensures unidirectional blood flow through the heart? | Valves, including the atrioventricular valves (tricuspid and mitral) and semilunar valves (pulmonary and aortic). |
| What sensory function does the respiratory system support, in addition to its roles in gas exchange and air distribution? | The sense of smell (olfaction), facilitated by specialized sensory epithelium. |
