What is a controllable risk factor for coronary artery disease
-
Smoking and stress
-
Age and family history
-
Race and gender
-
High cholesterol levels
Explanation
Correct Answer A: Smoking and stress
Explanation
Controllable risk factors are those that individuals can change or manage through lifestyle modifications. Smoking and stress are both controllable risk factors for coronary artery disease. Quitting smoking and managing stress can significantly reduce the risk of developing heart disease.
Why other options are wrong
B) Age and family history: These are non-controllable risk factors. Age and genetic predisposition (family history) cannot be changed.
C) Race and gender: These are also non-controllable risk factors. While certain races and genders may be at higher risk, they cannot be altered.
D) High cholesterol levels: Although high cholesterol is a risk factor, it can be managed through diet, exercise, and medication, making it a modifiable but not entirely controllable factor like smoking and stress.
How does urine travel from the kidneys to the outside of the body
-
Urethra to Bladder to Kidneys
-
Kidneys to Bladder to Urethra
-
Bladder to Kidneys to Urethra
-
Kidneys to Urethra to Bladder
Explanation
Correct Answer B. Kidneys to Bladder to Urethra
Explanation
Urine is produced in the kidneys, then travels through the ureters to the bladder for storage. When it is time to expel urine, it flows from the bladder through the urethra to the outside of the body.
Why other options are wrong
A: Urethra to Bladder to Kidneys
This sequence is incorrect because urine does not travel through the urethra before the bladder or kidneys.
C: Bladder to Kidneys to Urethra
This option reverses the proper order of urine flow. Urine is stored in the bladder, not the kidneys, before being expelled.
D: Kidneys to Urethra to Bladder
Urine doesn't travel from the kidneys directly to the urethra; it first moves to the bladder for storage.
Which communicable disease is caused by bacteria
-
Lice
-
MRSA
-
Cold sores
-
Chicken pox
Explanation
Correct Answer B: MRSA
Explanation
MRSA (Methicillin-resistant Staphylococcus aureus) is a bacterial infection that is resistant to many antibiotics, making it harder to treat. It is most commonly associated with skin infections but can also affect the bloodstream and other organs.
Why Other Options Are Wrong
A: Lice: Lice are parasitic infestations, not bacterial infections. They are small insects that live on the scalp or body and cause itching. Treatment typically involves using special shampoos or combing out the lice.
C: Cold sores: Cold sores are caused by the herpes simplex virus (HSV), not bacteria. This viral infection typically leads to blisters on the lips or around the mouth and can be spread by close contact, such as kissing.
D: Chicken pox: Chicken pox is caused by the varicella-zoster virus, not bacteria. It primarily affects children and is characterized by an itchy rash, fever, and flu-like symptoms. It is highly contagious through respiratory droplets.
What is the strategy recommended by Greg Kinobody to keep workouts fresh and exciting year-round in the Aggressive Fat Loss Program
-
Increase workout volume
-
Change exercise variations
-
Stick to the same exercises
-
Reduce rest time between sets
Explanation
Correct Answer B: Change exercise variations
Explanation
To keep workouts fresh and exciting, Greg Kinobody recommends changing exercise variations periodically. This helps avoid plateaus and keeps training engaging while still focusing on the same overall muscle groups.
Why other options are wrong
A) Increase workout volume: Increasing volume may be a strategy at times but is not the primary recommendation for maintaining excitement.
C) Stick to the same exercises: While consistency is important, sticking to the same exercises could lead to a plateau and reduced excitement over time.
D) Reduce rest time between sets: Reducing rest time can increase workout intensity, but it isn't the recommended strategy for keeping workouts fresh throughout the year.
What is the overall goal of the endocrine system? How do glands enable its function
-
Maintain blood pressure, Glands produce neurotransmitters
-
Control heart rate, Glands produce antibodies
-
Regulate body temperature, Glands produce enzymes
-
Influence growth and activities, Glands produce hormones
Explanation
Correct Answer D. Influence growth and activities, Glands produce hormones
Explanation
The overall goal of the endocrine system is to influence growth, metabolism, and various activities in the body. The glands of the endocrine system produce hormones, which are chemical messengers that regulate different bodily functions, including growth, metabolism, and mood.
Why other options are wrong
A: Maintain blood pressure, Glands produce neurotransmitters
While blood pressure regulation is one of the functions of the endocrine system, it doesn't focus on neurotransmitters, which are produced by the nervous system, not the endocrine system.
B: Control heart rate, Glands produce antibodies
The endocrine system influences heart rate indirectly, but antibodies are produced by the immune system, not the endocrine system. Hormones are the primary product of endocrine glands.
C: Regulate body temperature, Glands produce enzymes
The endocrine system does contribute to regulating body temperature, but it doesn't primarily function through enzymes. Instead, it relies on hormones for control and regulation.
How many days per week does Greg Kinobody recommend lifting weights on the Aggressive Fat Loss Program
-
3 days
-
7 days
-
5 days
-
2 days
Explanation
Correct Answer A: 3 days
Explanation
Greg Kinobody recommends lifting weights 3 days per week as part of the Aggressive Fat Loss Program. This allows for optimal muscle maintenance while still enabling fat loss, with sufficient recovery between workouts.
Why other options are wrong
B) 7 days: Lifting 7 days a week is too frequent for the goals of fat loss and muscle maintenance in this program, as recovery is essential.
C) 5 days: Lifting 5 days a week is not part of the recommended routine in the program. It focuses on 3 days for balance.
D) 2 days: Lifting only 2 days would not provide enough frequency for the muscle-building aspects of the program.
What is the primary function of the integumentary system
-
Protect body parts
-
Regulate body temperature
-
Transport nutrients
-
Produce hormones
Explanation
Correct Answer A: Protect body parts
Explanation
The integumentary system, which includes the skin, hair, nails, and associated glands, primarily serves to protect the body from environmental damage like pathogens, UV radiation, and dehydration. It also plays a role in regulating temperature and sensory perception.
Why Other Options Are Wrong
B: Regulate body temperature: While the integumentary system does help in regulating temperature through sweat glands and blood vessels, its primary function is protection. Temperature regulation is one of its secondary roles.
C: Transport nutrients: This is the role of the cardiovascular and digestive systems, not the integumentary system. The skin does not transport nutrients.
D: Produce hormones: Hormone production is primarily the role of the endocrine system. The integumentary system can produce vitamin D but does not produce hormones in the general sense.
What method could be used to measure subcutaneous fat
-
Skinfold calipers
-
Body fat percentage
-
BMI
-
Overall weight
Explanation
Correct Answer A: Skinfold calipers
Explanation
Skinfold calipers are used to measure the thickness of skinfolds at specific body sites. These measurements can then be used to estimate subcutaneous fat levels. It is a direct method to assess body fat distribution under the skin.
Why Other Options Are Wrong
B: Body fat percentage: While body fat percentage is an indicator of body composition, it is not a direct method for measuring subcutaneous fat. Other tools, such as calipers or DEXA scans, are used to determine fat percentage.
C: BMI: Body Mass Index (BMI) is a general measure of body weight relative to height and does not account for subcutaneous fat specifically. It is not a direct method for measuring fat distribution.
D: Overall weight: Overall weight measures total body mass but does not differentiate between fat and lean mass, making it an unsuitable method for assessing subcutaneous fat.
What is the most important organ associated with the respiratory system and why
-
Heart, for pumping blood
-
Lungs, for air exchange
-
Brain, for controlling breathing
-
Liver, for detoxification
Explanation
Correct Answer B. Lungs, for air exchange
Explanation
The lungs are the most important organ in the respiratory system because they are responsible for the exchange of gases—oxygen is taken in, and carbon dioxide is expelled. This gas exchange is essential for providing oxygen to the body's tissues and removing waste gases from the body.
Why other options are wrong
A: Heart, for pumping blood
The heart is crucial for pumping blood and transporting oxygen, but it is not directly involved in the process of air exchange, which is the primary function of the respiratory system.
C: Brain, for controlling breathing
The brain controls breathing but does not perform the actual gas exchange. It regulates the rate and depth of breathing, but the lungs are the organs responsible for oxygenating the blood.
D: Liver, for detoxification
The liver plays an important role in detoxification, but it is not part of the respiratory system and does not directly contribute to air exchange.
What does the CDC recommend to prevent fire and burns
-
Use candles for lighting during power outages
-
Install fire extinguishers in the kitchen
-
Maintain home smoke alarms on every floor
-
Keep flammable materials near heat sources
Explanation
Correct Answer C: Maintain home smoke alarms on every floor
Explanation
The CDC recommends maintaining smoke alarms on every floor of the home as a primary safety measure to prevent fires and burns. Smoke alarms help detect fires early, providing time to evacuate and reduce injury.
Why other options are wrong
A) Use candles for lighting during power outages: This is dangerous, as candles can cause fires.
B) Install fire extinguishers in the kitchen: While this is a good recommendation, smoke alarms are a more essential safety measure.
D) Keep flammable materials near heat sources: This is hazardous and increases the risk of fire. The CDC recommends keeping flammable materials away from heat sources.
