Questions and Answers

1.

What is the largest organ in your body?
- A.
  
  Large intestine
- B.
  
  Skin
- C.
  
  Brain
- D.
  
  Heart
Correct Answer
B. Skin

Explanation
The skin is the largest organ in the human body. It covers the entire external surface and protects the underlying tissues and organs from damage. The skin also helps regulate body temperature, prevents dehydration, and acts as a barrier against pathogens. It is composed of multiple layers and contains various structures, such as hair follicles, sweat glands, and sensory receptors.

2.

The skin does the following except:
- A.
  
  Help the body ingest sugary foods
- B.
  
  Protect our body
- C.
  
  Help us to have a sense of touch
- D.
  
  Keeps the body at the appropriate temperature
Correct Answer
A. Help the body ingest sugary foods

Explanation
The skin does not help the body ingest sugary foods. The main function of the skin is to protect our body from external factors like bacteria, viruses, and harmful substances. It also helps us have a sense of touch by containing sensory receptors. Additionally, the skin plays a role in regulating body temperature by controlling sweat production and blood flow. However, the ingestion of sugary foods is primarily facilitated by the digestive system, not the skin.

3.

The outermost layer of the skin is called:
- A.
  
  Epidermis
- B.
  
  Dermis
- C.
  
  Blubber
- D.
  
  Subcutaneous layer
Correct Answer
A. Epidermis

Explanation
The correct answer is Epidermis. The epidermis is the outermost layer of the skin. It acts as a protective barrier, preventing the entry of harmful substances and microorganisms into the body. It also helps regulate body temperature and contains cells that produce melanin, which gives color to the skin. The dermis is the layer beneath the epidermis, providing support and nourishment to the skin. Blubber is a layer of fat found in marine mammals, while the subcutaneous layer is the deepest layer of the skin, consisting of fat and connective tissue.

4.

Where does skin derives its color from?
- A.
  
  Blood vessels
- B.
  
  Dye
- C.
  
  The dermis
- D.
  
  Melanin
Correct Answer
A. Blood vessels

Explanation
Skin derives its color from melanin, a pigment produced by cells called melanocytes in the epidermis. Melanin is responsible for the various shades of skin color, ranging from light to dark. Blood vessels do not contribute to skin color, although they may affect the appearance of the skin due to factors like flushing or blushing. Dye is not a natural component of skin color, and the dermis is the layer of skin that contains structures like sweat glands and hair follicles, but it does not directly determine skin color.

The tiny tube in the skin that brings forth each hair on your body is called:
- A.
  
  Straw
- B.
  
  Pole
- C.
  
  Follicle
- D.
  
  Sweat gland
Correct Answer
C. Follicle

Explanation
The tiny tube in the skin that brings forth each hair on your body is called a follicle. The follicle is responsible for producing and nourishing the hair shaft, which grows out of the skin. It also contains the sebaceous gland, which produces oil to keep the hair and skin moisturized. Without the follicle, hair growth would not be possible.

What passes information to your brain when you touch and feel something?
- A.
  
  The dermis
- B.
  
  Nerve endings
- C.
  
  Pores
- D.
  
  Hair
Correct Answer
B. Nerve endings

Explanation
Nerve endings are responsible for passing information to the brain when we touch and feel something. These specialized sensory receptors are found throughout the body, including the skin. When we touch an object, the nerve endings in our skin detect the sensation and transmit signals to the brain, allowing us to perceive and interpret the tactile information.

What does blood vessels bring to skin cells?
- A.
  
  Carbon dioxide
- B.
  
  Food
- C.
  
  Sweat
- D.
  
  Oxygen and nutrients
Correct Answer
D. Oxygen and nutrients

Explanation
Blood vessels bring oxygen and nutrients to skin cells. Oxygen is essential for cellular respiration, which produces energy for the cells. Nutrients such as glucose, amino acids, and vitamins are necessary for the growth, repair, and maintenance of skin cells. Without a constant supply of oxygen and nutrients, the skin cells would not be able to function properly and may become damaged or die.

The natural oil in the skin is called:
- A.
  
  Sebum
- B.
  
  Melanin
- C.
  
  Sweat
- D.
  
  Vegetable oil
Correct Answer
A. Sebum

Explanation
Sebum is the natural oil produced by the sebaceous glands in the skin. It helps to moisturize and protect the skin, keeping it healthy and hydrated. Sebum also plays a role in regulating the skin's pH balance and protecting against bacteria and other harmful substances. Melanin is responsible for the color of the skin, hair, and eyes. Sweat is produced by sweat glands and helps to regulate body temperature. Vegetable oil is not naturally produced by the skin.

Which of the following can protect the skin for sun damage?
- A.
  
  Sunscreen
- B.
  
  A brimmed hat
- C.
  
  Lip balm
- D.
  
  All of the above
Correct Answer
A. Sunscreen

Explanation
Sunscreen can protect the skin from sun damage by forming a protective barrier on the skin's surface and absorbing or reflecting the harmful UV rays. It helps to prevent sunburn, premature aging, and reduces the risk of skin cancer. While a brimmed hat can provide shade and protect the face, neck, and scalp from direct sunlight, and lip balm can protect the lips from getting dry and chapped, they do not provide comprehensive protection against UV rays like sunscreen does. Therefore, the correct answer is sunscreen.

What is the major cause of goosebumps during cold weather?
- A.
  
  Gosling reflex
- B.
  
  Gag reflex
- C.
  
  Pilomotor reflex
- D.
  
  Patellar reflex
Correct Answer
C. Pilomotor reflex

Explanation
The major cause of goosebumps during cold weather is the pilomotor reflex. This reflex occurs when the muscles at the base of each hair follicle contract, causing the hair to stand on end. This reflex is an involuntary response to cold temperature in an attempt to trap a layer of air close to the skin, which helps to insulate the body and keep it warm.
