Heart & Sole: Unit 8 - Cardiovascular & Lymphatic Systems

These flashcards cover key vocabulary terms related to the cardiovascular and lymphatic systems as discussed in Unit 8.

Cardiovascular System

The system that delivers oxygen and nutrients to body tissues and removes wastes such as carbon dioxide via blood.

Lymphatic System

The system that carries excess interstitial fluid from tissues back to cardiovascular circulation and provides locations for immune cells to monitor the body.

Atrial Septal Defect (ASD)

A congenital heart defect characterized by a hole in the wall (septum) between the heart's two upper chambers (atria).

Deep Vein Thrombosis (DVT)

A condition where a blood clot forms in a deep vein, usually in the legs, which can lead to complications like pulmonary embolism.

Lymphedema

Swelling that occurs when lymphatic drainage is impaired, often resulting in fluid buildup in tissues.

Phagocytosis

The process by which certain cells engulf and digest foreign particles or pathogens.

Hemoglobin

A protein in red blood cells responsible for transporting oxygen throughout the body.

Capillaries

The smallest blood vessels where gas and nutrient exchange occurs between blood and tissues.

Edema

Swelling due to fluid buildup in tissues.

Oxygenated Blood

Blood that is rich in oxygen, typically flowing from the lungs to the heart and then to the rest of the body.

Deoxygenated Blood

Blood that is low in oxygen, typically returning to the heart from the body before it is pumped to the lungs.

Homeostasis

The maintenance of stable internal conditions in the body despite changes in the external environment.

Antigen

A foreign substance that triggers an immune response.

Lymph Nodes

Structures that filter lymph and house immune cells to monitor for infection.

Inflammation

The body’s localized response to injury or infection, characterized by redness, heat, swelling, and pain.

Aorta
