Circulatory System Review Flashcards
Veins
Carry blood from the tissue back to the heart has valves
Platelets
Help clot blood are cell fragments
Circulatory system
Transports oxygen and nutrients to the cells and carbon dioxide and waste out of the cell
Antigens
Proteins that activate a response from the immune system
Antibodies
Proteins that are produced by white blood cells to attack foreign substances
Pulmonary circulation
Right atrium to the right ventricle to the pulmonary artery trunk to the pulmonary artery to the lungs to the pulmonary veins to the left atrium is oxygen Rich
Blood types
A, B, AB, O
White Blood Cells
Leukocytes white blood cells have a nucleus red blood cells don’t
Systematic circulation
Left atrium to the left ventricle to the aorta to the arteries to the arterioles to the capillaries to the venues to the veins to the vena cava to the right atrium is oxygen poor
Aorta
Largest artery
Septum
Divides two sides of the heart
Blood pressure
Systolic (ventricles contract) 120, and diastolic (heart relaxes muscles fill) 80
Hemoglobin
Iron containing molecule that bonds with oxygen
Erythrocytes
Biconcave shape most numerous in blood contain hemoglobin produced in bone marrow have a nucleus but lose it
Left ventricle
Biggest chamber in heart because it is the most muscular
