, 1. 1. Question
Which of the following organ systems is not correctly paired with its function?
Respiratory/ breathing and gas exchange
Circulatory/ transport of substance to all tissues of the body
Digestive/ provide defense against infectious diseases
Nervous/ collecting, analyzing and integrating information that regulates intrinsic body
conditions and maintains behavioral patterns
Answer: Digestive/ provide defense against infectious diseases
The Immune system is responsible for providing defense and immunity against infectious
diseases.
The Digestive system is responsible for the breakdown and absorption of food.
The Respiratory system facilitates breathing and gas exchange.
The Nervous system is responsible for collecting, analyzing and integrating information that
regulates intrinsic body conditions and maintains behavioral patterns.
The Circulatory system is responsible for transport of substance to all tissues of the body.
2. 2. Question
The head is to the neck.
Proximal
Inferior
Superior
Superficial

,Answer: Superior
Superficial means that the structure is closer to the surface of the body.
Superior indicates that the structure is located at a relatively higher position
while inferior denotes a relatively lower position.
Proximal denotes a position that is relatively closer to the center of the body or the point of
attachment.
3. 3. Question
Which of the following organelles plays a vital role in the breaking down of macromolecules?

, Golgi Apparatus
Lysosomes
Ribosomes
Rough Endoplasmic Reticulum
Answer: Lysosomes
Ribosomes are the sites of protein synthesis. Ribosomes are attached to the Rough
Endoplasmic Reticulum, where the synthesized proteins are processed and sorted.
The Golgi Apparatus is then responsible for transporting and delivering synthesized proteins to
other regions of the cell or to the plasma membrane for exocytosis into the extracellular fluid.
Lysosomes, on the contrary, are responsible for digesting molecules/ substances being
transported inside the cell from the outside, such as during phagocytosis by macrophages.
