Study Notes
Cardiovascular System
- Aorta: Transports oxygen-rich blood from the heart to the body.
- Superior Vena Cava: Carries deoxygenated blood from the upper body to the heart's right atrium.
- Inferior Vena Cava: Carries deoxygenated blood from the lower body to the heart.
- Pulmonary Artery: Carries blood from the heart to the lungs.
- Pulmonary Vein: Carries oxygen-rich blood from the lungs to the heart.
- Right Atrium: Receives oxygen-poor blood from the body.
- Left Atrium: Receives oxygen-rich blood from the lungs.
- Right Ventricle: Pumps oxygen-poor blood to the lungs.
- Left Ventricle: Pumps oxygen-rich blood to the body.
- Aortic Valve: Controls blood flow into the aorta, maintaining one-way flow.
- Pulmonary Valve: Helps oxygen-poor blood reach the lungs.
- Tricuspid Valve: Controls blood flow from the heart's upper chamber (right atrium) to the lower chamber (right ventricle).
-
Layers of the heart:
- Epicardium: Outermost layer.
- Myocardium: Middle layer.
- Endocardium: Innermost layer.
-
Function of the heart:
- Produce bile: Important for digestion.
- Filter out toxic substances: Crucial for detoxification.
- Regulate blood levels: Maintaining homeostasis.
- Remove bacteria: Important for immunity.
- Make immune factors: Supporting the immune system.
- Clear bilirubin: Removing harmful byproducts.
- Regulate blood clotting: Important blood functions.
Hepatobiliary System
- Gallbladder: Pear-shaped organ located under the liver.
-
Function of gallbladder:
- Stores and concentrates bile produced by the liver.
- Part of the biliary tree.
-
Bile:
- Produced in the liver.
- Stored in the gallbladder.
- Aids in digestion, particularly fat absorption.
- Excreted.
- Liver cells (Hepatocytes): Functional cells of the liver.
- Kupffer cells: Resident macrophages in the liver.
