1. Which of the following is another name for a sweat gland?
- A. Ceruminous
- B. Sebaceous
- C. Sudoriferous
- D. Integumentary
Correct answer: C
Rationale: The correct answer is C: Sudoriferous. Sudoriferous glands are commonly known as sweat glands and are responsible for producing perspiration to regulate body temperature. Ceruminous glands produce earwax, sebaceous glands produce sebum (oil), and 'Integumentary' refers to the integumentary system, which includes the skin, hair, and nails. Choice A, Ceruminous glands, are responsible for producing earwax, not sweat. Choice B, Sebaceous glands, produce sebum (oil) to lubricate the skin and hair. Choice D, Integumentary, refers to the integumentary system, not a specific type of gland.
2. Which hormone is released by the adrenal glands in response to stress?
- A. Insulin
- B. Cortisol
- C. Adrenaline
- D. Glucagon
Correct answer: C
Rationale: Adrenaline is the correct answer. It is released by the adrenal glands in response to stress to prepare the body for the 'fight or flight' response. Adrenaline increases heart rate, dilates airways, and mobilizes energy stores to help the body deal with the perceived threat. Insulin (Choice A) is produced by the pancreas to regulate blood sugar levels, not in response to stress. Cortisol (Choice B) is another hormone released by the adrenal glands in response to stress, but it primarily helps regulate metabolism and immune response. Glucagon (Choice D) is also produced by the pancreas to increase blood sugar levels when they are low, not by the adrenal glands in response to stress.
3. What are the three types of capillaries?
- A. Continuous, fenestrated, sinusoidal
- B. Continuous, discontinuous, fenestrated
- C. Sinusoidal, alveolar, continuous
- D. Continuous, fenestrated, vascular
Correct answer: A
Rationale: The correct answer is A: Continuous, fenestrated, sinusoidal. Capillaries are classified into three types based on their permeability: continuous (least permeable), fenestrated (moderately permeable), and sinusoidal (most permeable). Choices B, C, and D are incorrect because they do not represent the three main types of capillaries. Choice B includes 'discontinuous' which is not a recognized type. Choice C includes 'alveolar' which is not a type of capillary, and Choice D includes 'vascular' which is too broad and not specific to capillary classification.
4. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?
- A. Limiting high-sodium foods in the diet
- B. Consuming adequate amounts of cranberry juice
- C. Holding urine in the bladder for long periods
- D. Getting regular moderate-intensity exercise
Correct answer: C
Rationale: Holding urine in the bladder for long periods is not recommended for optimal urinary system health. It can increase the risk of urinary tract infections and other bladder-related issues. When urine is held for a long time, bacteria have more time to multiply in the bladder, leading to infections. Additionally, holding urine for prolonged periods can also contribute to bladder distension, which may affect bladder function over time. Therefore, it is crucial to empty the bladder regularly to maintain good urinary system health. Limiting high-sodium foods helps reduce the risk of kidney stones and high blood pressure, while consuming cranberry juice may help prevent urinary tract infections by interfering with the adhesion of bacteria to the bladder walls. Regular moderate-intensity exercise promotes overall health, including maintaining a healthy weight and reducing the risk of chronic conditions that can impact the urinary system.
5. How is power related to time?
- A. Power is inversely proportional to time
- B. Power is directly proportional to time
- C. Power is unrelated to time
- D. Power is the product of time and work
Correct answer: C
Rationale: Power is a measure of how quickly work is done or energy is transferred. It is defined as the rate at which work is done or energy is transferred. Power is not directly or inversely proportional to time, as it depends on the amount of work done or energy transferred, not the duration over which it is done. The relationship between power and time is not a direct one, so power is unrelated to time. Choice A and B are incorrect because power's relationship with time is not one of direct or inverse proportionality. Choice D is incorrect because power is not simply the product of time and work; it is the rate at which work is done or energy is transferred, which can vary independently of time.
