QUESTIONS AND VERIFIED
SOLUTIONS LATEST UPD ATE
Question : Explain the principle of complementarity.
CORRECT ANSWER: Anatomy and physiology are
inseparable because function always reflects structure examples.) bones support and protect body organs because they contain hard mineral deposits and, blood flows in one direction through the heart because the heart has valves that prevent back flow.
Question : Levels of structural organization (in order of
increasing complexity)
CORRECT ANSWER : 1) Chemical Level- At this level
atoms, tiny building blocks of matter combine to form molecules such as water and proteins.2) Cellular Level- All cells have some common functions, but individual cells vary widely in size and shape, reflecting their unique functions in the body.3) Tissue Level- Tissues are groups of similar cells that have a common function

4) Organ Level- Organs are made up of different tissues.5) Organ (System) level- Organ systems consist of different organs that work together closely.6) Organismal Level- The human organism is made up of many organ systems.
Question : 11 Organ systems of the body (major
functions)
CORRECT ANSWER : 1) Integumentary System-
Forms the external body covering.2) Skeletal System- Protects and supports body organs.3) Muscular System- Allows manipulation of the environment, locomotion, and facial expressions.4) Lymphatic System- Picks up fluid leaked from blood vessels and returns it to the blood 5) Respiratory System- Keeps blood constantly supplied with oxygen and removes carbon dioxide.6) Digestive System- Breaks down food into absorbable units that enter the blood for distribution to body cells.

7) Nervous System- Fast acting control system of the body.8) Endocrine System- Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use.9)Cardiovascular System- Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients , wastes, etc.10) Urinary System- Eliminates nitrogenous wastes from the body.11) Reproductive System- Overall function is production of offspring.
Question : Negative Feedback Mechanisms
CORRECT ANSWER : In these systems, the output
shuts off the original stimulus or reduces intensity.
Examples: Regulation of body temperatures; Withdrawal
Reflex in which the hand is jerked away from a painful stimulus such as a broken glass; As blood volume drops, the hypothalamus of the brain is stimulated to release ADH to the blood.

Question : Positive Feedback Mechanisms
CORRECT ANSWER : The result or response enhances
the original stimulus so that the activity is accelerated.
Examples: Homeostatic mechanisms are the enhancement
of labor contractions during birth and blood clotting.
Question : Homeostatic Imbalance and Disease.
CORRECT ANSWER : Most disease can be regarded as
a result of the disturbance of homeostasis, which is known as homeostatic imbalance. Any abnormal condition is known as homeostatic imbalance.
Question : 9 Regions of Abdominopelvic Regions
CORRECT ANSWER : 1) Right Hypchondriac Region
(Top right) Organ: Liver Gallbladder
2) Right Lumbar Region (Middle Right) Organs:
Ascending Colon of large intestine 3) Right Iliac (inguinal) region- Cecum
