Ch 8 Notes Flashcard

Front

What are blood-spatter patterns?

Back

Blood-spatter patterns are formations of blood that occur as a result of different forces and angles impacting the blood, which can provide insights into the events surrounding a bloodshed incident.

Front

What factors influence the formation of blood-spatter patterns?

Back

The formation of blood-spatter patterns is influenced by the type of force applied (e.g., impact, gravity), the angle at which the blood is released, and the surface onto which it lands.

Front

Who described the A and B antigens in blood, and in what year?

Back

Carl Landsteiner described the A and B antigens in blood in the year 1901.

Front

What is the Rh factor in blood?

Back

The Rh factor is a specific protein that can be present on the surface of red blood cells, determining whether blood is Rh-positive or Rh-negative.

Front

When was the Rh factor identified in relation to the A and B antigens?

Back

The Rh factor was identified later than the A and B antigens.

Front

What type of blood cell is responsible for carrying respiratory gases?

Back

Red blood cells are responsible for carrying respiratory gases such as oxygen and carbon dioxide.

Front

What happens during agglutination in the circulatory system?

Back

Agglutination occurs when antibodies in the blood react with antigens on the surface of red blood cells, leading to clumping that can obstruct blood flow.

Front

What could happen if agglutination occurs during a blood transfusion?

Back

If agglutination occurs during a blood transfusion, blood could cease to flow, potentially leading to serious complications.

Front

What are the main components of blood?

Back

The main components of blood include red blood cells, white blood cells, platelets, and plasma.

Front

What is the function of white blood cells?

Back

White blood cells are responsible for the immune response, helping to protect the body against infections and foreign invaders.
