Anatomy

1. During exercise, heart rate increases to deliver more oxygen to the body's tissues. What other cardiovascular response also increases?

Correct answer: A

Rationale: The correct answer is A: 'Blood pressure decreases.' When the heart rate increases during exercise to deliver more oxygen to the body's tissues, the blood pressure also tends to decrease. This is due to the enhanced efficiency of the heart in pumping blood, resulting in a lower pressure exerted on the blood vessel walls. In contrast, options B and D are incorrect as blood vessel diameter typically widens (dilates) during exercise to facilitate increased blood flow, and blood viscosity does not usually thicken during exercise. Option C is a distractor as blood flow to muscles indeed increases during exercise to meet the higher demand for oxygen and nutrients.

2. Approximately how many muscles are there in the human body?

Correct answer: D

Rationale: The correct answer is D. There are over 600 muscles in the human body. Muscles are responsible for movement, posture, and generating heat in the body. The exact number of muscles can vary slightly from person to person, but it is generally accepted that there are over 600 muscles in the human body. These muscles work together to allow us to perform various movements and activities throughout our daily lives.

3. Define power in physics.

Correct answer: b

Rationale: Power is the rate at which work is done or energy is transferred or converted.

4. The author likely intended to use the phrase "interconnected sensors" to emphasize...

Correct answer: B

Rationale: "Interconnected" highlights the integration and communication between sensors, indicating a complex network approach.

5. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

Correct answer: C

Rationale: Interjections express emotions or sudden feelings. "Ouch" conveys a feeling of pain.

6. . Edema, characterized by swelling due to fluid buildup, can be a sign of:

Correct answer: D

Rationale: Edema, which is the accumulation of fluid in tissues leading to swelling, can be caused by various medical conditions. Heart failure can result in fluid retention due to the heart's inability to pump effectively, leading to edema. Liver disease can cause edema by impairing the liver's ability to produce proteins that help maintain fluid balance. Dysfunction of the lymphatic system can also lead to edema, as the lymphatic vessels play a crucial role in draining excess fluid from tissues. Therefore, all the options (heart failure, liver disease, and lymphatic system dysfunction) can contribute to the development of edema, making 'All of the above' the correct answer.
