Study Notes
Blood Components
- Plasma: Main fluid component of blood containing water, electrolytes, nutrients, hormones, and proteins including immunoglobulins and clotting factors.
- Hemoglobin (Hb): Key protein in red blood cells responsible for oxygen transport throughout the body.
White Blood Cells (Leukocytes)
- Five main types of mature white blood cells:
- Lymphocytes: Integral for adaptive immunity.
- Monocytes: Transform into macrophages upon entering tissues, crucial for engulfing pathogens and debris.
- Neutrophils: First responders to infections, effective in fighting bacteria.
- Eosinophils: Important in combating parasites and involved in allergic reactions.
- Basophils: Release histamine during inflammatory responses.
Lymphatic System
- Lymph Vessels: Walled, valved structures that transport lymph fluid, playing a significant role in immune responses and fluid homeostasis.
-
Lymph Nodes: Small, bean-shaped structures that:
- Produce lymphocytes.
- Filter harmful substances from lymph fluid.
- Contain macrophages for digesting cellular debris and pathogens.
- Essential for the training and development of T lymphocytes.
Spleen
- Organ located in the upper left abdomen.
- Functions include:
- Filtering blood to remove worn-out red blood cells.
- Storing a reserve supply of blood for emergencies.
