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 deoxygenated blood from the body and pumps it to the right ventricle.
- The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
- The right ventricle pumps deoxygenated blood to the lungs.
- The left ventricle pumps oxygenated blood to the body.
- The aortic valve controls blood flow into the aorta and keeps blood moving in one direction.
- The pulmonary valve helps oxygen-poor blood reach the lungs.
- The tricuspid valve controls blood flow from the right atrium to the right ventricle.
Blood Vessels
- Arteries carry blood away from the heart.
- Arterioles are smaller arteries.
- Capillaries are thin-walled blood vessels where gas exchange occurs.
- Veins carry blood back to the heart.
- Venules are smaller veins.
- The walls of arteries can regulate blood vessel diameter.
- Veins have one-way valves to prevent backflow.
- Capillaries have thin walls for efficient gas exchange.
Blood Pressure
- Systolic pressure is the peak pressure during heart contraction.
- Diastolic pressure is the pressure when the heart relaxes.
- Blood pressure is measured in millimeters of mercury (mmHg).
- The systemic circulation carries oxygenated blood through arteries and capillaries to tissues.
Hepatobiliary System
- The liver is involved in nutrient metabolism, detoxification, and bile production.
- The liver produces bile, which helps digest fats.
- The liver filters out toxic substances.
- The gallbladder stores and concentrates bile.
- The gallbladder helps with fat digestion and absorption.
- Hepatocytes are functional cells of the liver
- Kupffer cells are resident macrophages that remove foreign debris.
Urinary System
- The kidneys remove waste products and excess fluid.
- The kidneys help maintain homeostasis.
- The kidneys regulate acid-base balance and electrolyte concentrations.
- The kidneys regulate extracellular fluid volume and blood pressure.
- Parts of the urinary system include the kidneys, ureters, bladder, and urethra.
- Causes of kidney problems can include congenital abnormalities, high blood sugar, and high blood pressure.
