Macrophages are the predominant cell type in chronic inflammation, contributing to tissue repair and the immune response.

Type I hypersensitivity reactions are mediated by IgE antibodies, leading to allergic responses.

High-grade tumors typically exhibit increased mitotic activity, presence of necrosis, and poorly differentiated cells, making 'All of the above' the correct answer.

Rigor mortis occurs due to the depletion of ATP, which is necessary for muscle relaxation.

Chronic alcohol consumption induces CYP2E1, which increases the metabolism of acetaminophen to toxic metabolites, raising the risk of liver damage.

St. John's Wort is known to induce CYP450 enzymes, which can lead to decreased effectiveness of drugs metabolized by these enzymes.

Epithelioid cell formation is a characteristic feature of granulomatous inflammation, often seen in conditions like tuberculosis.

The acid-fast bacilli stain is used to identify Mycobacterium tuberculosis due to its unique cell wall properties.

Grapefruit juice inhibits CYP3A4, which is responsible for the metabolism of many statins, leading to increased statin levels and risk of side effects.

The acid-fast bacilli stain is the most common laboratory method used to identify Mycobacterium tuberculosis due to its unique cell wall properties.

Squamous cell carcinoma is the most common lung cancer type associated with smoking.

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 85% of cases.

Apoptosis is a form of programmed cell death that occurs in a regulated manner, distinct from necrosis.

Livor mortis is primarily caused by gravity, which causes blood to settle in the lowest parts of the body.

Neurons are the primary cell type in nervous tissue, responsible for transmitting signals throughout the body.

Neutrophils are the first responders to sites of acute inflammation, playing a crucial role in the initial immune response.

Tumors are primarily classified as benign or malignant based on their histological appearance, which reflects their cellular characteristics and behavior.

Combining MAO inhibitors with tyramine-rich foods can lead to a hypertensive crisis due to excessive norepinephrine release.

Ciliated columnar epithelium helps in moving mucus and trapped particles out of the respiratory tract, aiding in protection and clearance.

Lipid accumulation within the arterial wall is a primary histological feature of atherosclerosis.

Staphylococcus aureus produces various exotoxins that contribute to its pathogenicity, including enterotoxins and toxic shock syndrome toxin.

Staphylococcus aureus produces a polysaccharide capsule that inhibits phagocytosis, allowing it to evade the host immune response.

Warfarin primarily works by inhibiting vitamin K epoxide reductase, which is essential for the synthesis of vitamin K-dependent clotting factors.

Ischemia primarily leads to ATP depletion due to reduced blood flow, which impairs cellular functions and can lead to cell death.

Fibrosis is the primary mechanism of tissue repair, involving the deposition of collagen and extracellular matrix components.

Immunohistochemistry is the primary method used for the histopathological diagnosis of tumors, allowing for the identification of specific antigens in tissue sections.

Helicobacter pylori is primarily transmitted via the fecal-oral route, leading to gastrointestinal infections.

Most viruses are primarily transmitted through airborne droplets, especially respiratory viruses.

Neisseria gonorrhoeae is primarily transmitted through sexual contact, leading to gonorrhea.

Algor mortis refers to the cooling of the body after death, which begins within a few hours.
