What is perfusion?

• The circulation of an adequate amount of blood to meet the cells’ current needs.

• The process of breathing in oxygen.

• The removal of waste products from the body.

• The digestion of food in the stomach.

What may cause cellular damage in cases of poor perfusion?

• Excessive oxygen supply

• Buildup of waste products

• Increased nutrient absorption

• Enhanced blood flow

What does shock refer to in the context of pathophysiology?

• A state of increased blood circulation

• A state of collapse and failure of the cardiovascular system

• A condition of high blood pressure

• A temporary increase in heart rate

What system's failure leads to shock?

• Digestive system

• Nervous system

• Cardiovascular system

• Respiratory system

Which of the following best describes the cardiovascular system?

• A network of nerves

• A system of muscles

• A system of heart, blood vessels, and blood

• A collection of organs

What is the function of the heart in the perfusion triangle?

• To store blood

• To act as a pump

• To filter blood

• To oxygenate blood

What is blood pressure?

• The force of blood against the walls of blood vessels

• The speed of blood flow in the veins

• The temperature of blood in the body

• The volume of blood in the heart

What is required for adequate perfusion besides a working cardiovascular system?

• Adequate oxygen exchange in the lungs

• Adequate protein synthesis

• Adequate fat storage

• Adequate muscle contraction

What is the primary cause of hypovolemic shock?
