12 Questions
The ______ is the increased blood flow to a specific area of the body.
hyperemia
The ______ is the blockage of a blood vessel by an embolus.
embolism
The ______ is the death and decay of tissue due to lack of blood supply.
gangrene
The ______ is the bleeding from blood vessels.
hemorrhage
The ______ is the accumulation of blood in the abdominal cavity.
hemoperitoneum
The ______ is the presence of blood in a joint cavity.
hemoarthrosis
What is the primary cause of infarction, and how does it lead to tissue damage?
The primary cause of infarction is the blockage of blood flow, which leads to reduced oxygen supply to the tissues, resulting in tissue damage.
How does thrombosis differ from embolism, and what is the common outcome of both?
Thrombosis is the formation of a blood clot in a blood vessel, while embolism is the blockage of a blood vessel by an embolus. Both can lead to ischemia and potentially infarction.
What is the relationship between edema and hemoperitoneum, and how do they affect the body?
Edema is the abnormal accumulation of fluid in tissues, while hemoperitoneum is the accumulation of blood in the abdominal cavity. Both can cause swelling, pain, and discomfort, and may lead to further complications if left untreated.
What is the difference between hemorrhage and epistaxis, and how are they treated?
Hemorrhage is bleeding from blood vessels, while epistaxis is a specific type of hemorrhage that occurs in the nose. Treatment for hemorrhage depends on the location and severity, while epistaxis is often treated with direct pressure or cauterization.
How do venous congestion and ischemia contribute to the development of gangrene?
Venous congestion can lead to reduced blood flow, resulting in ischemia, which can cause tissue damage and eventually lead to gangrene.
What is the relationship between hyperemia and ischemia, and how do they affect tissue health?
Hyperemia is increased blood flow to a specific area, while ischemia is reduced blood flow. Hyperemia can help to prevent ischemia, but excessive hyperemia can also lead to tissue damage.
Study Notes
Blood Circulation and Blood Flow
- Hyperemia: Increased blood flow to a specific area of the body, resulting in increased oxygenation and nutrient delivery.
Blood Clots and Blockages
- Thrombosis: Formation of a blood clot in a blood vessel, which can impede blood flow.
- Embolus: A traveling blood clot or foreign material that can obstruct a blood vessel.
- Embolism: Blockage of a blood vessel by an embolus, potentially leading to tissue damage.
- Ischemia: Reduced blood supply to tissues, often leading to tissue damage or infarction.
Tissue Damage and Death
- Infarction: Tissue death due to blocked blood flow, resulting in tissue necrosis.
- Gangrene: Death and decay of tissue due to lack of blood supply, often leading to amputation.
Fluid Accumulation and Bleeding
- Edema: Abnormal accumulation of fluid in tissues, causing swelling and potentially leading to tissue damage.
- Hemorrhage: Bleeding from blood vessels, which can lead to hypovolemic shock.
- Epistaxis: Nosebleed, often due to trauma or vascular malformations.
- Hemoptysis: Coughing up blood from the respiratory tract, often indicative of respiratory disease.
- Hematemesis: Vomiting blood from the gastrointestinal tract, often indicative of gastrointestinal disease.
Accumulation of Blood
- Hemothorax: Accumulation of blood in the chest cavity, often due to trauma or surgical complications.
- Hemopericardium: Accumulation of blood in the pericardial sac, often due to cardiac trauma or disease.
- Hemoperitoneum: Accumulation of blood in the abdominal cavity, often due to trauma or surgical complications.
- Hematocele: Accumulation of blood in a body cavity or sac, often due to trauma or surgical complications.
- Hemoarthrosis: Presence of blood in a joint cavity, often due to trauma or joint disease.
