Blood: An Overview

Blood is a crucial body fluid that performs numerous vital functions. Blood is composed of red blood cells, white blood cells, plasma, and platelets. Here’s a quick look at its primary functions:

  • Transportation: Carries oxygen and nutrients to cells, and removes waste products like carbon dioxide.
  • Regulation: Maintains body temperature and pH balance.
  • Protection: Fights against infections through the immune system.

Major Blood Types

There are several major blood types, governed by the presence or absence of specific antigens on red blood cells. The most recognized classification system is the ABO system.

ABO System

The ABO system classifies blood into four main types:

  • Type A: Has A antigens on red cells and B antibodies in the plasma.
  • Type B: Has B antigens with A antibodies in the plasma.
  • Type AB: Has both A and B antigens in the plasma, without any corresponding antibodies.
  • Type O: Lacks both A and B antigens but has both antibodies.

Rh Factor

Rh factor is another crucial component, resulting in positive or negative blood types. If your blood has the Rh factor, you’re Rh-positive (e.g., A+). If not, you’re Rh-negative (e.g., A-).

Genetic Influences on Blood Types

Your blood type is inherited from your parents, determined by alleles they pass on. The genetic makeup strongly dictates the likelihood of having certain blood types.

Blood Type Compatibility and Transfusions

Blood type compatibility is critical for safe transfusions. Incompatibility can cause severe transfusion reactions.

  • Type O negative is considered a universal donor.
  • AB positive individuals are universal recipients.

Significance of Knowing Your Blood Type

Knowing your blood type is essential for medical emergencies, pregnancy, and health-related issues. Certain blood types may predispose individuals to specific diseases.
