Can thrombus in v. portae cause arterial emboli in art. pulmonalis?

  • a) yes

  • b) no

Can thrombus in v. portae cause arterial emboli in art. pulmonalis?

  • a) yes

    • so since the emboli would get stuck in the liver first (as the portal vein → liver → inferior VC) but to get to the inferior vena cava the embolus would get stuck in the smaller venous vessels in liver first before it can make it out to the IVC → RA → Pulmonary artery

    • A thrombus in the portal vein is confined to the venous system, specifically the splanchnic venous circulation, which drains blood from the gastrointestinal tract, spleen, and pancreas into the liver.

    • From the portal vein, blood flows through the liver and into the hepatic veins, which then drain into the inferior vena cava and ultimately return to the right atrium of the heart.

Precancerous lesions may have a reverse development (back to normal tissue):

  • a) yes

  • b) no

Precancerous lesions may have a reverse development (back to normal tissue):

a) yes

  • CONTRADICTION with Q77?? - no, but can be confused - that talks about tumours, this talks about precancerous lesions which can literally be a few atypical/dysplasic cells that could be removed/correct by the body when the causative agent is removed.

b) no

  • Yes, it is true that precancerous lesions may regress or revert to normal tissue in some cases. This process, called reverse development or regression, can occur due to various factors, including the removal of the underlying cause, improvements in immune function, or lifestyle changes. Here are some examples and contributing factors:

    Examples of Regression:

    1. Cervical Dysplasia:

      • Mild cervical dysplasia (CIN1), caused by HPV infection, often regresses on its own, especially in younger individuals. The body's immune system clears the virus, leading to normal tissue restoration.

    2. Barrett's Esophagus:

      • In some cases, early interventions like addressing gastroesophageal reflux disease (GERD) through medications, lifestyle changes, or surgery may lead to regression of Barrett's esophagus.

    3. Oral Leukoplakia:

      • Stopping smoking or eliminating other irritants can lead to the resolution of leukoplakic patches, a common precancerous lesion in the mouth.

    4. Colorectal Adenomas:

      • Small adenomas in the colon may regress with dietary changes, anti-inflammatory medications, or removal of other risk factors.

    Factors Influencing Regression:

    • Immune System: A healthy immune response can help clear abnormal cells.

    • Elimination of Risk Factors: Stopping smoking, reducing alcohol consumption, or treating infections (e.g., HPV, H. pylori) can promote regression.

    • Medical Interventions: Topical treatments, vaccinations, or medications may reverse certain lesions.

    • Lifestyle Modifications: Improved diet, exercise, and weight management can help.

    However, not all precancerous lesions regress. Some may persist or progress to cancer if not monitored or treated. Regular follo

extra info:

Parenchyme

  • Definition: The functional tissue of an organ, as opposed to the supportive or structural tissue (stroma).

  • Function: Performs the primary work of the organ (e.g., hepatocytes in the liver for metabolism, alveolar cells in the lungs for gas exchange).

  • Example: In the kidney, the nephrons form the parenchyme.

Mesenchyme

  • Definition: A type of loosely organized, embryonic connective tissue that gives rise to many structures, including connective tissue, bone, cartilage, and blood.

  • Origin: Derived from the mesoderm during embryogenesis.

  • Function: Plays a key role in the development and repair of structural and connective tissues.

  • Example: Mesenchymal stem cells give rise to osteoblasts (bone cells), fibroblasts (connective tissue), and adipocytes (fat cells).

Epithelial

  • Definition: A type of tissue composed of tightly packed cells that form protective barriers, line surfaces, and perform absorption, secretion, or sensory functions.

  • Origin: Derived from ectoderm, mesoderm, or endoderm, depending on location.

  • Function: Protects underlying structures, facilitates selective permeability, secretes substances, and absorbs nutrients.

  • Example: Skin epidermis, lining of the digestive tract, and glandular tissue.
