Study Notes
Heart and Blood Vessels
- The heart functions as a pump to circulate blood throughout the body, delivering oxygen and nutrients while removing waste products.
- Blood vessels, including arteries, veins, and capillaries, form a complex network that transports blood to various tissues and organs.
Blood Composition
- The fluid part of blood is called plasma, which accounts for about 55% of blood volume and contains water, electrolytes, proteins, hormones, and waste products.
Function of Red Blood Cells (RBC)
- Red blood cells (erythrocytes) are responsible for transporting oxygen from the lungs to body tissues and carrying carbon dioxide from the tissues back to the lungs for exhalation.
- They contain hemoglobin, a protein that binds oxygen and enables its transport.
Nutrient Transport
- Blood transports nutrients, particularly glucose and fatty acids, absorbed from the small intestine to cells and tissues throughout the body for energy and metabolism.
Blood Coloration
- The red color of blood is primarily due to the presence of hemoglobin in red blood cells, which contains iron that binds to oxygen, reflecting red light.
