Study Notes
Cardiovascular System
- Heart: Main organ for pumping blood throughout the body.
- Apex: The tip of the heart where the heartbeat can be felt.
- Base: The top part of the heart where major vessels emerge.
- Right auricle: The small pouch-like structure on the right side of the heart.
- Right atrium: Chamber that receives deoxygenated blood from the body.
- Left auricle: Similar to the right auricle but located on the left side.
- Left atrium: Chamber that receives oxygenated blood from the lungs.
- Interventricular septum: Wall separating the left and right ventricles.
- Left ventricle: Pumps oxygenated blood to the body.
- Right ventricle: Pumps deoxygenated blood to the lungs.
Vascular Structures
- Ascending aorta: Major artery carrying oxygen-rich blood away from the heart.
- Pulmonary trunk: Carries deoxygenated blood from the right ventricle to the lungs.
- Aortic arch: Curved portion of the aorta that gives rise to major arteries.
- Brachiocephalic artery: Supplies blood to the right arm and head.
- Common carotid arteries: Supply blood to the head and neck.
- Subclavian arteries: Supply blood to the arms.
- Femoral artery: Major artery supplying blood to the legs.
- Renal arteries and veins: Supply blood to and from the kidneys.
- Internal and external iliac arteries: Supply blood to the pelvis and legs.
Respiratory System
- Lung: Primary organ for gas exchange.
- Trachea: Windpipe that conducts air to the lungs.
- Diaphragm: Muscle that aids in respiration by expanding and contracting the thoracic cavity.
- Bronchi: Main passageways that direct air into the lungs.
Digestive System
- Liver: Processes nutrients from the digestive tract.
- Stomach: Digests food and churns it into a semi-liquid form.
- Small Intestine: Main site for nutrient absorption.
- Large Intestine: Absorbs water and forms feces.
- Cecum: First part of the large intestine receiving material from the small intestine.
- Rectum: Final section of the large intestine leading to the anus.
- Pancreas: Produces enzymes and hormones for digestion and blood sugar regulation.
Excretory System
- Kidney: Filters blood to produce urine, regulating water and electrolytes.
- Ureter: Tube that carries urine from the kidney to the bladder.
- Bladder: Stores urine until it is excreted.
Reproductive System
- Testes: Male reproductive organs producing sperm and hormones.
- Epididymis: Stores and matures sperm.
- Vas deferens: Transports sperm from the epididymis to the urethra.
- Ovaries: Female reproductive organs producing eggs and hormones.
Lymphatic and Immune System
- Thymus: Organ where T-cells mature, important for immune response.
- Spleen: Filters blood and helps fight infections.
Anatomical Membranes
- Parietal pericardium: Tough outer layer surrounding the heart.
- Visceral pericardium: Inner layer covering the heart surface.
- Parietal pleura: Lines the chest cavity and covers the lungs.
- Visceral pleura: Membrane directly attached to the lungs.
- Parietal peritoneum: Lines the abdominal cavity.
- Visceral peritoneum: Covers the organs within the abdominal cavity.
Miscellaneous
- Mediastinum: Central area in the thoracic cavity housing the heart, great vessels, and other structures.
- Hilum: Area where vessels and nerves enter and exit an organ, such as the lungs or kidneys.
