Brain damage is likely if intervention occurs __________ after the heart stops.
2-4 Minutes
4-6 Minutes
6-10 Minutes
None of the above
In emergency medicine, brain damage is likely if intervention occurs 4-6 minutes after a heart stops. The brain quickly loses oxygen after the heart stops pumping blood, leading to possible brain damage or death, hence quick action like CPR is crucial.
Explanation:In the field of emergency medicine, it is generally considered that brain damage is likely if intervention occurs 4-6 minutes after the heart stops. The reason for this is that the brain starts to lose oxygen immediately after the heart ceases to pump blood, leading to irreversible brain damage or death. It is therefore crucial that cardiopulmonary resuscitation (CPR) is initiated as soon as possible after cardiac arrest to increase the chances of survival and minimize potential brain damage.

Final answer:
Selecting business equipment necessitates a balance between modern efficiency and avoiding rapid obsolescence. Desired characteristics include reliability, productivity, and resources that support evolvability and resilience, while undesirable traits involve clinging to outdated technology that hinders performance.
Explanation:
When selecting equipment for a business, it is essential to strike a balance between acquiring the very latest models and relying on outdated technology. The most desirable characteristic is that the equipment efficiently meets the current needs of the business, ensuring high productivity, efficiency, and reliability without necessitating frequent replacements. On the other hand, the most undesirable characteristic is that the equipment is obsolescent, hindering performance and potentially causing costly downtime.
The selection should be informed by the equipment's performance characteristics, including accuracy, precision, and selectivity, among others. Additionally, factors such as evolvability, which allows for future upgrades and adaptations, and the trade-off between upfront costs and long-term benefits should be considered. The goal is to ensure that any equipment acquired contributes positively to the resilience and competitiveness of the business while being cost-effective.
What function do capillaries serve in the cardiovascular system?
A.
carry blood to the brain
B.
return blood to the lungs
C.
help control body temperature
D.
replace old blood cells
Capillaries are the smallest and most numerous blood vessels in the cardiovascular system. They play a crucial role in facilitating the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. However, their primary function in the context of the cardiovascular system is to help control body temperature. Thus, option C is correct.
Capillaries are located in close proximity to body tissues and are responsible for regulating heat exchange between the blood and the tissues. When body temperature rises, capillaries dilate, allowing increased blood flow to the skin and facilitating the release of excess heat through the process of vasodilation. This helps in cooling down the body and maintaining its temperature within a normal range.
Conversely, when body temperature drops, capillaries constrict, reducing blood flow to the skin and minimizing heat loss through the process of vasoconstriction. This helps in conserving heat and preventing the body from getting too cold.
