Study Notes
Circulatory System
- Consists of heart, blood vessels, and blood
- Functions: transporting gases, nutrients, waste, and hormones, protecting against infection, and regulating body temperature
Anatomy and Physiology
- Anatomy: the structure of an organism
- Physiology: the function(s) of an organism's anatomy, including chemical and physical processes
- Homeostasis: the state of balance and optimal function of all body systems
Composition of Blood
- Red Blood Cells (RBCs):
- Contain hemoglobin (Hgb) and carry oxygen throughout the body
- Produced in the bone marrow
- Also known as erythrocytes
- Live for around 120 days
- White Blood Cells (WBCs):
- Develop from stem cells that provide immunity
- Produced in the bone marrow
- Also known as leukocytes
- Live from six hours to several years
- Platelets:
- The smallest blood cell
- Responsible for the clotting of blood
- Produced in the bone marrow
- Also known as thrombocytes
- Live for about 10 days
Hemostasis and Coagulation
- Hemostasis: an ongoing process to stop bleeding and repair blood vessels after vascular injury
- Coagulation: a critical component of hemostasis, forming a stable blood clot
- Hemostasis progresses through four responses:
- Vasoconstriction
- Formation of a platelet plug
- Coagulation
- Fibrinolysis
Blood Vessels
- Tubular structures that carry blood throughout the body
- Link together the pulmonary and systemic systems
- Three main types: capillaries, arteries, and veins
Pulmonary System
- Carries deoxygenated blood from the heart to the lungs and oxygenated blood back to the heart
Systemic System
- Carries oxygenated blood from the heart through the body and deoxygenated blood back to the heart
Capillaries
- Exchange oxygen and carbon dioxide between the blood and cells through their thin walls
Arteries
- Carry oxygenated blood away from the heart to the rest of the body
- Have thick, muscular walls
- The pressure exerted on the arteries creates a pulse that can be felt
Veins
- Carry deoxygenated blood back to the heart from the rest of the body
- Have thinner walls than arteries
- Valves prevent backflow of blood
Obtaining Blood Samples
- The antecubital fossa is the primary venipuncture site
- Median cubital vein is the first choice for routine venipuncture
- Cephalic vein is the second choice
- Basilic vein is the last choice
