Free
Multiple Choice
Answer:

Answer:

Various bodily systems have distinct, but critical functions. These systems have different terms used to describe them, so it is important to know what bodily system performs what function. For instance, it is critical to known what system facilitates oxygen and carbon dioxide exchange.
Gaseous exchange is not conducted by the nervous system. It conducts sensory inputs and regulates the involuntary processes. The muscular system is also not directly involved in the process of gaseous exchange, though it does serve to facilitate the movement of critical regions of the system. Lastly, the reproductive system does not serve to mediate the process of gaseous exchange.
Hence, the options a, b and d are incorrect.
The respiratory system is responsible for the exchange of gases like the carbon dioxide and oxygen. The system works via the lungs, which exchange gases with the environment, and the bloodstream, which transports the gases and nutrients throughout the body.
Hence, the correct answer is option img .

Free
Multiple Choice
Answer:

Answer:

In order to understand human anatomy, it is important to understand how various body parts are classified and categorized on the basis of their structure and function. Hence, it is critical to be familiar with the anatomical terminology used to describe aspects of the human body such as the skin.
The striated and visceral layers are used to refer to the human muscle, not the epidermis. Likewise, the terms muscular and hematopoietic do not describe the layers of the human skin. The trachea, pharynx, bronchiole and alveolus are parts of the human respiratory tract.
Hence, the options a, c and d are incorrect.
The skin of the human's is distinguished into 3 layers that are dermis, subcutaneous and epidermis. The epidermis is the outermost layer, the dermis is places deeper beneath the surface, and the subcutaneous region is the innermost region.
Hence, the correct answer is option img .

For the following questions, select the one best answer. What role does DNA play in the human body?
Free
Multiple Choice
Answer:

Answer:

Deoxyribonucleic acid, or DNA, plays a major role in the lifespan of most organisms. It is a highly conserved molecule across multiple organisms and species. It even transcends the barrier between prokaryotes and eukaryotes by being present in both.
Despite its highly conserved and fundamental nature as a biomolecule, DNA does not directly contribute to many important life processes. For instance, it is not involved hormonal changes, catabolism, anabolism, or digestion.
Hence, options a, c and d are incorrect.
The primary purpose of DNA is to provide a genetic blueprint for the organism. This blueprint serves as the basis for the ribonucleic acid (RNA) and protein molecules that will function within the organism. These molecules, in turn, mediate the various life processes of the organism.
Hence, the correct answer is option img .

Review Figure 6-14. It is remarkable that our skeletal and muscular systems allow us to move in so many directions. Think about your joint movements while you walk to a chair to sit down. What movements would you go through to prepare to have a blood specimen collected? As you move your arm, then hand/wrist, then ankle/foot, describe the movements of flexion and extension, circumduction, pronation and supination, and dorsiflexion. Say the words as you move your limbs and match the movements with the words. Remember that for some patients, these same easy movements may be painful or impossible because of their medical conditions (e.g., arthritis). (Reference Figure 6-14) img
