A chemical process that destorys most, but not necessarily all, harmful organisms on environmental surfaces is
- A.
Disinfecting
- B.
Sanitizing
- C.
Cleaning
- D.
Sterilizing
Correct Answer
A. DisinfectingExplanation
Disinfecting is the correct answer because it refers to a chemical process that eliminates or reduces harmful organisms on environmental surfaces, but it does not guarantee the complete elimination of all organisms. Sanitizing typically refers to reducing the number of microorganisms to a safe level, while cleaning involves removing dirt and debris from surfaces. Sterilizing, on the other hand, is a process that completely eliminates all forms of life, including microorganisms.Rate this question:

Which type of tissue contracts and moves various parts of the body?
- A.
Nerve tissue
- B.
Muscle tissue
- C.
Connective tissue
- D.
Epithelial tissue
Correct Answer
B. Muscle tissueExplanation
Muscle tissue is responsible for contracting and moving various parts of the body. It is composed of specialized cells called muscle fibers that have the ability to contract and generate force, allowing for movement and locomotion. Nerve tissue, on the other hand, transmits signals and information throughout the body, while connective tissue provides support and connects different structures. Epithelial tissue covers and protects the body's surfaces. Therefore, muscle tissue is the correct answer as it specifically relates to the contraction and movement of body parts.Rate this question:

Deoxygenated blood flows from the heart to the lungs for oxygenation and waste removal and then returns that blood to the _____ so oxygen-rich blood can be delivered to the body.
- A.
Left atrium
- B.
Right atrium
- C.
Left ventricle
- D.
Right ventricle
Correct Answer
A. Left atriumExplanation
Deoxygenated blood flows from the heart to the lungs for oxygenation and waste removal. After the blood is oxygenated in the lungs, it needs to be returned to the heart so that it can be pumped to the rest of the body. The left atrium receives the oxygen-rich blood from the lungs and then contracts to push the blood into the left ventricle. From the left ventricle, the oxygen-rich blood is pumped out to the body through the aorta. Therefore, the left atrium is the correct answer as it is the chamber that receives the oxygenated blood from the lungs before it is distributed to the body.Rate this question:

Correct Answer
B. Helps to equalizeExplanation
Blood helps to equalize the body's temperature by distributing heat throughout the body. It carries heat from the core to the extremities, helping to maintain a consistent temperature throughout. Additionally, blood vessels near the skin can dilate or constrict to release or conserve heat, further aiding in temperature regulation.Rate this question:

The _______ system distributes blood throughout the body.
- A.
Integumentary
- B.
Circulatory
- C.
Respiratory
- D.
Lymphatic
Correct Answer
B. CirculatoryExplanation
The circulatory system is responsible for distributing blood throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood from the lungs to the rest of the body, delivering nutrients and oxygen to the cells. It also carries waste products, such as carbon dioxide, away from the cells to be eliminated. The blood vessels, including arteries, veins, and capillaries, transport the blood throughout the body. Overall, the circulatory system plays a crucial role in maintaining the body's homeostasis and ensuring the proper functioning of all organs and tissues.Rate this question:

The _________ system makes blood and oxygen available to the body structures through breathing and eliminating carbon dioxide.
- A.
Nervous
- B.
Reproductive
- C.
Respiratory
- D.
Endocrine
Correct Answer
C. RespiratoryExplanation
The respiratory system is responsible for providing blood and oxygen to the body structures through the process of breathing. It takes in oxygen from the air and eliminates carbon dioxide, ensuring that the body receives the necessary oxygen for cellular respiration and removes waste products. The nervous system controls and coordinates the body's functions, the reproductive system is involved in reproduction, and the endocrine system regulates hormones. Therefore, the correct answer is respiratory.Rate this question:

Which nerve fibers are distributed to the arrector pili muscle attached to the hair follicles?
- A.
Impulse nerve fibers
- B.
Sensory nerve fibers
- C.
Secretory nerve fibers
- D.
Motor nerve fibers
Correct Answer
D. Motor nerve fibersExplanation
Motor nerve fibers are responsible for controlling the contraction of muscles. In the case of the arrector pili muscle, which is attached to the hair follicles, motor nerve fibers are distributed to this muscle. When these motor nerve fibers are stimulated, they cause the arrector pili muscle to contract, resulting in the hair standing on end or goosebumps. Therefore, motor nerve fibers are the correct answer in this case.Rate this question:
-
- 34.
__________ fibers react to heat, cold, touch, pressure, and pain
- A.
Motor nerve
- B.
Sensory nerve
- C.
Secretory nerve
- D.
Complex nerve
Correct Answer
B. Sensory nerveExplanation
Sensory nerves are responsible for transmitting signals from the sensory organs to the central nervous system. These nerves are specialized to detect and respond to various stimuli such as heat, cold, touch, pressure, and pain. When these sensory fibers are stimulated by these external factors, they generate electrical signals that are then transmitted to the brain for interpretation. Therefore, sensory nerves are the correct answer as they react to heat, cold, touch, pressure, and pain.Rate this question:

Skin gets its strength, form, and flexibility from _______.
- A.
Collagen and keratin
- B.
Sebum and melanin
- C.
Keratin and elastin
- D.
Collagen and elastin
Correct Answer
D. Collagen and elastinExplanation
Collagen and elastin are proteins found in the skin that provide strength, form, and flexibility. Collagen is responsible for the skin's structural support and helps maintain its firmness, while elastin allows the skin to stretch and bounce back to its original shape. Together, these proteins contribute to the overall health and appearance of the skin. Sebum and melanin, on the other hand, are not directly responsible for the skin's strength, form, and flexibility.Rate this question:

- A.
Nail bed
- B.
Cuticle
- C.
Matrix
- D.
Ligament
Correct Answer
A. Nail bedExplanation
The nail bed is the portion of the living skin that supports the nail plate as it grows towards the free edge. It is responsible for providing nutrients and oxygen to the nail plate, allowing it to grow and remain healthy. The nail bed is located underneath the nail plate and is connected to the matrix, which is responsible for producing new nail cells. The cuticle is the layer of skin that protects the nail bed, while a ligament is a band of tissue that connects bones or holds organs in place.Rate this question:

If a client has ridges running vertically down the length of the natural nail plate, it is recommended that you _______.
- A.
Aggressively file the nail plate
- B.
Carefully buff the nail plate
- C.
Thin the nail plate
- D.
Remove the free edge
Correct Answer
B. Carefully buff the nail plateExplanation
If a client has ridges running vertically down the length of the natural nail plate, it is recommended to carefully buff the nail plate. Buffing the nail plate helps to smooth out the ridges and create a more even surface. Aggressively filing the nail plate can cause damage and thinning the nail plate may not be necessary in this case. Removing the free edge is not relevant to addressing the ridges.Rate this question:
