Study Notes
Liver Anatomy
- Location: Right upper quadrant of the abdominal cavity, beneath the diaphragm
- Shape: Irregular, triangular shape with two lobes (right and left)
- Functions:
- Detoxification: filters blood from the digestive system
- Metabolism: regulates energy, nutrient, and hormone production
- Storage: stores glycogen, vitamins, and minerals
- Structures:
- Lobules: functional units of the liver, consisting of hepatic cells and sinusoids
- Hepatic cells: responsible for metabolic and detoxification processes
- Sinusoids: specialized blood vessels that allow for exchange of substances between blood and hepatic cells
- Bile ducts: transport bile from the liver to the gallbladder and small intestine
Digestive System
- Overview: a complex system that breaks down food into nutrients for absorption and utilization
- Organs:
- Mouth: mechanical and chemical breakdown of food
- Esophagus: muscular tube that transports food to the stomach
- Stomach: mixes food with digestive enzymes and acids
- Small intestine: absorbs nutrients into the bloodstream
- Pancreas: produces digestive enzymes and hormones
- Liver: produces bile and aids in digestion and nutrient absorption
- Gallbladder: stores and releases bile into the small intestine
- Large intestine: absorbs water, electrolytes, and vitamins, and eliminates waste
Heart Structure
- Overview: a muscular, hollow organ that pumps blood throughout the body
- Chambers:
- Right atrium: receives oxygen-depleted blood from the body
- Right ventricle: pumps blood from the right atrium to the lungs
- Left atrium: receives oxygen-rich blood from the lungs
- Left ventricle: pumps blood from the left atrium to the rest of the body
- Valves:
- Tricuspid valve: separates the right atrium and ventricle
- Pulmonary valve: separates the right ventricle and pulmonary artery
- Mitral valve: separates the left atrium and ventricle
- Aortic valve: separates the left ventricle and aorta
- Blood vessels:
- Pulmonary artery: carries oxygen-depleted blood from the heart to the lungs
- Aorta: carries oxygen-rich blood from the heart to the rest of the body
Liver Anatomy
- Located in the right upper quadrant of the abdominal cavity, beneath the diaphragm
- Irregular, triangular shape with two lobes (right and left)
- Performs detoxification by filtering blood from the digestive system
- Regulates energy, nutrient, and hormone production through metabolism
- Stores glycogen, vitamins, and minerals
- Consists of functional units called lobules, comprising hepatic cells and sinusoids
- Hepatic cells are responsible for metabolic and detoxification processes
- Sinusoids are specialized blood vessels that enable exchange of substances between blood and hepatic cells
- Bile ducts transport bile from the liver to the gallbladder and small intestine
Digestive System
- A complex system that breaks down food into nutrients for absorption and utilization
- Involves mechanical and chemical breakdown of food in the mouth
- Food is transported to the stomach through the esophagus
- Stomach mixes food with digestive enzymes and acids
- Small intestine absorbs nutrients into the bloodstream
- Pancreas produces digestive enzymes and hormones
- Liver produces bile and aids in digestion and nutrient absorption
