Study Notes
Cardiovascular System
- The aorta transports oxygen-rich blood from the heart to the body.
- The superior vena cava carries deoxygenated blood from the upper body to the heart.
- The inferior vena cava carries deoxygenated blood from the lower body to the heart.
- The pulmonary artery carries blood from the heart to the lungs.
- The pulmonary vein carries oxygen-rich blood from the lungs to the heart.
- The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
- The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
- The right ventricle pumps oxygen-poor blood to the lungs.
- The left ventricle pumps oxygen-rich blood to the body.
- The aortic valve controls blood flow into the aorta.
- The pulmonary valve helps oxygen-poor blood reach the lungs.
- The tricuspid valve controls the flow of blood from the right atrium to the right ventricle.
Blood Vessels
- Arteries carry blood away from the heart.
- Arterioles regulate blood vessel diameter.
- Capillaries are thin-walled blood vessels for exchange.
- Veins return blood to the heart.
- Venules collect blood from capillaries.
- Blood vessel walls regulate blood vessel diameter.
Blood Pressure
- Systolic pressure is the peak pressure during heart contraction.
- Diastolic pressure is the pressure when the heart relaxes.
Hepatobiliary System
- The liver produces bile to aid fat digestion.
- The liver filters out toxic substances.
- The liver regulates blood levels, removes bacteria, and produces immune factors.
- It clears bilirubin and regulates blood clotting.
- The gallbladder stores and concentrates bile produced by the liver.
- Bile helps with fat digestion and absorption.
Kidney and Urinary System
- Kidneys remove waste and excess fluid.
- Homeostasis, acid-base balance, electrolyte concentrations, and extracellular fluid volume are regulated.
- Kidneys regulate blood pressure.
- Parts of the urinary system: kidneys, ureters, bladder, urethra.
Kidney Problems/Diseases
- Congenital abnormalities can cause kidney problems.
- High blood sugar (diabetes) and high blood pressure can damage kidneys.
