Which of the following statements best describes reversible cell injury?
Cellular damage is severe, leading to irreversible changes.
The cell undergoes changes but can return to its normal state if the stimulus is removed.
The cell adapts to the injury by increasing its size.
The injury primarily affects the extracellular matrix.
In the context of cell adaptation, what is hypertrophy?
Increase in the number of cells
Decrease in cell size
Increase in cell size
Change in cell shape
What is a common consequence of prolonged ischemia?
Cellular swelling
Fatty change
Necrosis
Apoptosis
Which type of adaptation occurs in response to chronic stress?
Hyperplasia
Hypertrophy
Atrophy
Metaplasia
Which organelle is often affected during cell injury?
Endoplasmic reticulum (ER)
Golgi apparatus
Nucleus
Lysosomes
What is the main cause of cell injury during hypoxia?
Increased oxygen supply
Decreased ATP production
Enhanced mitochondrial function
Elevated pH
Which cellular adaptation is commonly seen in skeletal muscles during regular exercise?
Hypertrophy
Atrophy
Metaplasia
Hyperplasia
In the context of cell injury and adaptation, which process involves programmed cell death and is crucial for maintaining tissue homeostasis?
Hypertrophy
Necrosis
Apoptosis
Hyperplasia
Which of the following statements accurately describes the process of inflammation?
Inflammation is a specific immune response that targets only bacteria.
Inflammation is a protective response to injury or infection, involving blood vessel dilation and immune cell recruitment.
Inflammation is a long-term process that aims to repair damaged tissues.
Inflammation is primarily mediated by red blood cells.
What is the primary purpose of inflammation in the body?
To generate energy
To initiate blood clotting
To protect against injury and infection
To regulate body temperature
Which cells play a key role in the inflammatory response by releasing histamines?
Red blood cells
T cells
Mast cells
Platelets
What is the main function of neutrophils during inflammation?
Phagocytosis of pathogens
Antibody production
Tissue regeneration
Hormone secretion
Which of the following is a symptom commonly associated with acute inflammation?
Fever
Fibrosis
Chronic pain
Scar formation
How does inflammation contribute to the repair process?
By causing more damage to tissues
By promoting the formation of scar tissue
By initiating the proliferation of new cells
By suppressing the immune system
Which chemical mediator is responsible for promoting vasodilation during inflammation?
Interleukin-1
Prostaglandins
Tumor necrosis factor (TNF)
Interferon
What is the purpose of the clotting cascade during inflammation?
To trap pathogens
To prevent immune cell migration
To stop bleeding and initiate tissue repair
To increase blood viscosity
Which phase of wound healing involves the formation of granulation tissue?
Inflammatory phase
Proliferative phase
Remodeling phase
Resolution phase
What is a common feature of chronic inflammation?
Rapid onset
Resolution of the inflammatory process
Continuous tissue damage
Limited immune cell infiltration
How does chronic inflammation differ from acute inflammation?
Chronic inflammation has a rapid onset.
Chronic inflammation is a protective response.
Acute inflammation is characterized by prolonged duration.
Acute inflammation is usually resolved, while chronic inflammation persists.
What is the role of cytokines in the inflammatory response?
Initiating blood clotting
Enhancing the inflammatory process
Breaking down extracellular matrix
Suppressing immune cell activity
