Study Notes
Blood
- Blood is a specialized connective tissue composed of plasma and formed elements
- Plasma makes up about 55% of blood volume and is mostly water
- Plasma contains dissolved solutes, such as proteins, electrolytes, nutrients, and waste products
- Formed elements make up about 45% of blood volume and include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)
- Erythrocytes are responsible for oxygen transport
- Leukocytes are responsible for immune defense
- Thrombocytes are responsible for blood clotting
Immune System
- The immune system is a complex network of cells, tissues, and organs that work together to defend the body against foreign invaders
- The immune system can be divided into two main branches: the innate immune system and the adaptive immune system
- The innate immune system is the first line of defense against pathogens and is non-specific
- The adaptive immune system is a more specific defense system that is able to target specific pathogens and remember them for future encounters
- The adaptive immune system is responsible for immune memory, which allows the body to mount a faster and more effective response upon subsequent exposures to the same pathogen
