Study Notes
Circulatory Systems Overview
- The circulatory system is responsible for transporting oxygen, nutrients, metabolic waste, cells of the immune system (WBCs), and hormones throughout the body.
- Specialized systems exist for different purposes, including Systemic, Pulmonary, Portal, Coronary, and Fetal (additional details in separate heart videos).
Blood Circulation Systems
-
Systemic Circulation:
- A high-pressure system.
- Carries oxygenated blood from the left side of the heart to body tissues.
- Returns deoxygenated blood to the right side of the heart.
-
Pulmonary Circulation:
- A low-pressure system.
- Carries deoxygenated blood from the right side of the heart to the lungs.
- Returns oxygenated blood to the left side of the heart.
- Pulmonary arteries carry blood away from the heart (hence oxygen-poor).
- Pulmonary veins carry blood toward the heart (hence oxygen-rich).
Blood Vessels
- Arteries: Carry blood away from the heart.
- Veins: Carry blood back to the heart.
- Capillaries: Found between arteries and veins; site of gas exchange.
Systemic Circulation Vessels
- Key vessels include the Common carotid, Aortic arch, Brachial, Aorta, Femoral, Popliteal, Posterior tibial, and Dorsalis pedis (for arteries and veins named similarly).
- Many veins share the same name as the corresponding artery, with some exceptions.
Applications
- Knowing the location of arteries allows calculation of heart rate by taking the pulse.
- Practice locating radial, carotid, brachial, femoral, popliteal, posterior tibial, and dorsalis pedis pulses.
Circulatory System Function
- Blood flow within the circulatory system is a closed circuit.
- Blood travels through the body via arteries, veins, and capillaries.
Additional Notes
- The blood flow in the circulatory system is a closed loop.
