,1. Which level of structural organization is considered the simplest?
a. Cellular
b. Chemical
c. Tissue
d. Organ
The chemical level includes atoms and molecules, which are the building blocks
for all other levels of structure.
2. Which organ system is primarily responsible for transporting nutrients, gases,
and wastes?
a. Respiratory
b. Digestive
c. Cardiovascular
d. Endocrine
The cardiovascular system circulates blood, which transports nutrients, gases,
and waste products.
3. What is the function of the mitochondria?
a. Protein synthesis
b. Lipid metabolism
c. ATP production
d. DNA replication
Mitochondria are known as the “powerhouses” of the cell because they produce
ATP through cellular respiration.
4. Which plane divides the body into anterior and posterior parts?
a. Sagittal
,b. Transverse
c. Frontal
d. Oblique
The frontal (coronal) plane divides the body into front (anterior) and back
(posterior) sections.
5. Homeostasis is maintained primarily through:
a. Positive feedback
b. Negative feedback
c. Enzyme secretion
d. Reflex arcs
Negative feedback loops are the most common mechanisms to maintain stable
internal conditions.
6. Which tissue type lines the body's surfaces and cavities?
a. Muscle
b. Connective
c. Epithelial
d. Nervous
Epithelial tissue covers and lines surfaces and cavities and forms glands.
7. The axial skeleton includes all of the following except:
a. Skull
b. Vertebrae
c. Clavicle
d. Sternum
The clavicle is part of the appendicular skeleton, not the axial skeleton.
, 8. Which organ is found in the right upper quadrant (RUQ)?
a. Liver
b. Appendix
c. Sigmoid colon
d. Spleen
The liver primarily resides in the right upper quadrant.
9. Which cell organelle is responsible for protein synthesis?
a. Lysosome
b. Ribosome
c. Golgi apparatus
d. Peroxisome
Ribosomes are the sites of protein synthesis in cells.
10. Which part of the neuron receives incoming signals?
a. Axon
b. Dendrite
c. Soma
d. Synapse
Dendrites are branched extensions of the neuron that receive incoming stimuli.
11. The primary function of melanin in the skin is to:
a. Keep the skin hydrated
b. Provide elasticity
c. Protect against UV radiation
