Cardiovascular System Overview

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.
