Details the composition of blood, focusing on plasma and the different types of blood cells it contains.
Erythrocytes (RBCs) transport carbon dioxide mainly in the form of bicarbonate ions (HCO₃⁻).
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Hemoglobin in RBCs binds with oxygen for transport to body tissues and also helps in CO₂ transport in the blood.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
WBCs are involved in immune response, while platelets are responsible for blood clotting.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
The spleen breaks down old and damaged RBCs, hence called the "graveyard of RBCs."
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Neutrophils and monocytes are phagocytic WBCs that engulf and digest foreign particles and pathogens.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Hemoglobin contains iron, which binds to oxygen for transport in the blood.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
RBCs have a lifespan of around 120 days and are responsible for oxygen transport.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Leukocytes (WBCs) are responsible for immune responses and fighting infections.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
The spleen acts as the "graveyard of RBCs," breaking down old and damaged red blood cells.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Plasma distributes heat throughout the body, helping in temperature regulation.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
Erythrocytes (RBCs) are not WBCs; they are responsible for oxygen transport.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Blood - Plasma and Formed Elements
RBCs primarily transport oxygen, while WBCs are involved in the immune response.
