Circulatory System and Forensics Study Guide

These flashcards cover key concepts related to the circulatory system, exercise physiology, and forensic analysis of blood and fingerprints.

Circulatory System

The system responsible for the transportation of blood, nutrients, gases, and wastes throughout the body.

Pulmonary Circuit

Moves deoxygenated blood between the heart and lungs for oxygenation.

Systemic Circuit

Moves oxygenated blood between the heart and the rest of the body.

Atria

The upper chambers of the heart that receive blood (Right from the body; Left from the lungs).

Ventricles

The lower chambers of the heart that pump blood out (Right to the lungs; Left to the body).

Valves

Structures in the heart that prevent backflow of blood; includes Tricuspid, Bicuspid/Mitral, Pulmonary, Aortic.

Septum

The wall that divides the left and right sides of the heart.

Blood Pressure

The pressure of circulating blood against the walls of blood vessels.

Atherosclerosis

A condition characterized by narrowed blood vessels due to plaque buildup, increasing the risk of heart attacks and strokes.

A-B-O Blood Typing

A system that classifies blood types based on the presence of A and B antigens on red blood cells.

Type A Blood

Blood type with A antigens on red blood cells and B antibodies in plasma.

Type B Blood

Blood type with B antigens on red blood cells and A antibodies in plasma.

Type AB Blood

Universal recipient blood type with both A and B antigens, and no antibodies.

Type O Blood

Universal donor blood type with no A or B antigens, and both A and B antibodies.

Rh Factor

A protein that can be present (positive) or absent (negative) on the surface of red blood cells.

Agglutination

The clumping of cells, typically occurring when an antigen meets its corresponding antibody.

Forensic Techniques

Methods used in crime scene investigations, such as fingerprinting and blood typing, for identifying individuals.
