What are the main components of blood and their classifications?
What are the main components of blood and their classifications?
Blood is classified into a liquid part, plasma, and a solid part consisting of red blood cells, white blood cells, and platelets.
Describe the role of red blood cells in the body's physiology.
Describe the role of red blood cells in the body's physiology.
Red blood cells transport oxygen from the lungs to body tissues and carry carbon dioxide back to the lungs for exhalation.
How does blood contribute to temperature regulation in the body?
How does blood contribute to temperature regulation in the body?
Blood maintains body temperature by distributing heat generated by metabolism and facilitating heat loss through the skin.

Study Notes
Red Blood Cells
- Biconcave disc shape
- Contains hemoglobin, a pigment that gives blood its red color
- Lack a nucleus
- Travel in capillaries
Function of Red Blood Cells
- Transport oxygen from lungs to the body
- Carbon dioxide transport from body to lungs
- Bright red blood indicates oxygenated blood
- Dull red blood indicates deoxygenated blood
Blood
- Liquid part: Plasma
- Solid Part:
- Red Blood Cells (Erythrocytes)
- White Blood Cells (Leucocytes)
- Platelets (thrombocytes)
Functions of Blood
- Transports oxygen and carbon dioxide
- Maintains body temperature
- Transports nutrients
- Forms blood clots for wound healing
- Fights pathogens and infections
Adaptation of Red Blood Cells for Oxygen Transport
- Hemoglobin: carries oxygen to body cells.
- Thin-walled: quick diffusion of oxygen from alveoli to blood
- Lack of Nucleus: provides more space for hemoglobin
- Small and flexible: squeezes into narrow capillaries
- Biconcave shape: large surface area for gas absorption
White Blood Cells
- Irregular shape with a large central nucleus
Function of White Blood Cells
- Part of the body's immune system
- Protect against infections, cancers, and diseases
Phagocytosis
- A process where phagocytes (a type of white blood cell) ingest and destroy pathogens
Adaptations of White Blood Cells for Protection
- Irregular shape: changes for quick travel to infection sites
- Cytoplasm and flexible membranes: allows for engulfing of pathogens
- Engulfing pathogens: helps defend against infection
