Study Notes
Circulatory System
- Carries materials to all cells and removes waste products
- Four components:
- Vehicle (Blood): Carries materials
- Conduits (Blood Vessels): Tubes for blood travel
- Motive Force (Heart): Blood pump
- Exchange Areas (Capillaries): Material exchange
Blood Components
- Plasma: Fluid containing proteins, sugars, irons, vitamins, hormones, and makes up 55% of blood volume
- Red Blood Cells (RBCs): Biconcave discs without nuclei or mitochondria
- Shape increases surface area for oxygen diffusion
- Approximately 4.2-5.9 million cells/cubic mm of blood
- Contains hemoglobin, a protein that carries oxygen
- White Blood Cells (WBCs): Five main types, contribute 1% of blood volume
- Essential for immunity and protection against illness
- Produced in bone marrow and stored in blood and lymphatic tissues
- Approximately 5,000 to 11,000 WBCs per cubic mm of blood
- Platelets: Help blood clotting by clumping together
- Release clotting factors
- Approximately 150,000-350,000 platelets per cubic mm of blood
Bone Marrow
- Nutrient-dense tissue located in bone cavities
- Red bone marrow: Produces blood cells from stem cells
- Yellow bone marrow: Stores fat and can produce red blood cells during emergencies
Blood Functions
- Vehicle for oxygen, nutrients, carbon dioxide, waste, hormones, and antibodies
- Provides immunity through phagocytosis of foreign particles and antibody production
- Involved in blood clotting to prevent blood loss and seal wounds
- Temperature control: Network of vessels under the skin acts as a radiator
Blood Grouping Systems
- ABO System: Blood types: A, B, AB, and O
- Antigens: Proteins on red blood cell membranes
- Antibodies: Proteins in plasma that target specific antigens
- Rh System: Rh antigen present on some red blood cells
- Rh+: Antigen present
- Rh-: Antigen absent
Blood Transfusion
- Donor blood should not have antigens that the recipient's blood has antibodies against
- O- blood is the universal donor: No A or B antigens
- AB blood is the universal receiver: No antibodies to attack donor antigens
Hemolytic Disease in Newborn
- Rh+ father and Rh- mother: Mother can develop Rh antibodies after exposure to fetal Rh antigens
- Subsequent pregnancies with Rh+ fetus: Maternal Rh antibodies can cross the placenta and damage fetal red blood cells
- RhoGam Injection: Manufactured antibodies that neutralize maternal Rh antibodies
Inheritance of ABO Blood Groups
- Inherited from both parents
- A or B individuals can be homozygous or heterozygous for the antigen
