Questions and Answers

What are the functions of blood?

The functions of blood include transport of gases, nutrients and waste products; transport of regulatory molecules; regulation of pH and osmosis; maintenance of body temperature; protection against foreign substances; and clot formation.

What is thrombosis and what are the common abnormalities of hemostasis associated with it?

Thrombosis is the formation of an unwanted clot within a blood vessel. Common abnormalities of hemostasis associated with thrombosis include acute myocardial infarction, deep-vein thrombosis, pulmonary embolism, and acute ischemic stroke.

What are the treatments for thrombosis?

The treatments for thrombosis include anticoagulants and fibrinolytics.

What is the difference between a thrombus and an embolus?

A thrombus is a clot that adheres to a vessel wall, while an embolus is an intravascular clot that floats in the blood. Signup and view all the answers

What are the two types of arterial and venous thrombosis and their causes?

Arterial thrombosis is caused by atherosclerosis and consists of a platelet-rich clot. Venous thrombosis is caused by inappropriate activation of the coagulation cascade and results in a fibrin-rich clot. Signup and view all the answers

Study Notes

Functions of Blood

Regulates body temperature
Transports oxygen and nutrients to cells
Removes waste products from the body
Maintains pH balance
Supports immune function
Regulates blood pressure

Hemostasis and Thrombosis

Hemostasis: the process of stopping bleeding from damaged blood vessels
Thrombosis: the formation of a blood clot within a blood vessel
Thrombosis associated with abnormal hemostasis, which can lead to stroke, heart attack, and pulmonary embolism

Thrombus and Embolus

Thrombus: a stationary blood clot that forms in a blood vessel
Embolus: a blood clot that breaks loose and travels through the bloodstream, potentially blocking a vessel
Thrombus can become an embolus if it breaks loose

Types of Thrombosis

Arterial thrombosis: formation of a blood clot in an artery, can lead to heart attack or stroke
Venous thrombosis: formation of a blood clot in a vein, can lead to pulmonary embolism
Causes: injury, immobility, surgery, cancer, and genetic disorders

Formation of Unwanted Clot

Occurs when blood flow is interrupted, and platelets aggregate
Examples of associated conditions: deep vein thrombosis, pulmonary embolism, stroke, and heart attack

Types of Thrombus

White thrombus: platelet-rich, forms in arteries, and causes heart attack or stroke
Red thrombus: fibrin-rich, forms in veins, and causes pulmonary embolism

Bleeding Disorders

Failure of hemostasis can lead to bleeding disorders, such as hemophilia A and B

Treatment Options for Thrombosis

Anticoagulant medications to prevent further clotting
Thrombolytic medications to dissolve the clot
Filters or stents to prevent embolization
Surgery to remove the clot
