Study Notes
Circulatory System Vocabulary
-
Vein
- Carries deoxygenated blood back to the heart.
-
Aortic Valve
- Located between the left ventricle and the aorta; regulates blood flow from the heart to the body.
-
Myocardium
- Thick muscular tissue forming the middle layer of the heart; responsible for the heart's contractions.
-
Pericardium
- A double-layered membrane surrounding the heart, providing protection and reducing friction.
-
Thrombocyte
- Also known as platelets; essential for blood clotting to prevent excessive bleeding.
-
Artery
- Transports oxygenated blood away from the heart to various body tissues.
-
Septum
- Muscular wall that divides the heart into left and right sides, preventing the mixing of oxygenated and deoxygenated blood.
-
Hemoglobin
- A complex protein found in red blood cells; binds to oxygen for transport through the bloodstream.
-
Ventricle
- Lower chamber of the heart; responsible for pumping blood out to the lungs and the rest of the body.
-
Endocardium
- A smooth layer of cells lining the interior of the heart, facilitating blood flow.
-
Pulmonary Valve
- Located between the right ventricle and the pulmonary artery; controls blood flow from the heart to the lungs.
-
Atria
- Upper chambers of the heart; receives blood from the body and lungs before it enters the ventricles.
-
Erythrocyte
- Commonly known as red blood cells; responsible for transporting oxygen and carbon dioxide in the blood.
-
Diastole
- The phase of the heart cycle when the heart muscle relaxes; allows chambers to fill with blood.
-
Plasma
- The liquid component of blood, making up about 55% of its volume; contains water, salts, and proteins.
-
Capillaries
- Microscopic blood vessels connecting arterioles and venules; facilitate the exchange of oxygen, carbon dioxide, and nutrients.
-
Bicuspid Valve
- Also known as the mitral valve; situated between the left atrium and left ventricle; allows blood to flow in one direction.
-
Leukocyte
- White blood cells that play a critical role in the immune response, helping to fight infections.
-
Systole
- The period during which the heart muscle contracts; pumps blood out of the chambers.
-
Blood
- A connective tissue that circulates throughout the body, carrying nutrients, gases, and waste products.
