How is the term "anatomy" defined?
✔✔ The study of the structure and organization of living organisms.
What is the definition of "physiology"?
✔✔ The study of the functions and processes of living organisms and their parts.
What are the key levels of organization in the human body?
✔✔ Chemical, cellular, tissue, organ, organ system, and organismal levels.

,What is the significance of homeostasis?
✔✔ Maintaining a stable internal environment despite external changes is crucial for the survival
and proper functioning of an organism.
What are the major organ systems in the human body?
✔✔ The integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic,
respiratory, digestive, urinary, and reproductive systems.
What is "homeostatic regulation"?
✔✔ The process by which the body maintains a stable internal environment through feedback
mechanisms.
How do feedback mechanisms contribute to homeostasis?
2
,✔✔ Feedback mechanisms regulate physiological processes by using sensors to detect changes,
control centers to process the information, and effectors to produce responses.
What is the difference between positive and negative feedback mechanisms?
✔✔ Negative feedback mechanisms work to counteract deviations from a set point, while
positive feedback mechanisms amplify changes in the system.
What are the primary functions of the integumentary system?
✔✔ Protecting the body, regulating temperature, and providing sensory information.
How does the skeletal system contribute to overall body function?
✔✔ By providing structural support, facilitating movement, protecting internal organs, and
producing blood cells.
What role does the muscular system play in the human body?
3
, ✔✔ Facilitating movement through muscle contractions, maintaining posture, and generating
heat.
How does the nervous system communicate with different parts of the body?
✔✔ Through electrical impulses transmitted via neurons that regulate bodily functions and
respond to stimuli.
What are the main functions of the endocrine system?
✔✔ Regulating physiological processes through hormone secretion, which influences growth,
metabolism, and reproduction.
How does the cardiovascular system support homeostasis?
✔✔ By transporting nutrients, gases, hormones, and waste products throughout the body and
regulating blood pressure.
What is the role of the lymphatic system in the body?
