Anatomy - Circulatory System Flashcards
Which WBCs are granulocytes?
Neutrophils, eosinophils, basophils
Hemostasis
The cessation of bleeding
Basophils
Immune cells that secrete histamine and heparin
B Lymphocytes
Lymphocytes that create antibodies
What on the surface of RBCs determines ABO blood types?
Glycolipids
Serotonin
A vasoconstrictor released by platelets in response to bleeding
Plasmin
A substance that dissolves blood clots once the damage has been repaired
Coronary Sulchus
Wall of flesh that separates the chambers of the heart
Auracle
Ear-shaped extensions of atria
Ligamentum Arteriosum
A ligament that tethers the aorta and pulmonary artery
Remnant of the ductus arteriosus
Tendinous Cords
Tendons that prevent the atrioventricular valves from turning inside-out during systole
Papillary Muscles
Muscles inside the ventricles that connect to the tendinous cords and therefore the atrioventricular valves
Gap Junction
Electrical junction found at the intercalated discs of cardiac muscles
Foramen Ovale
A hole connecting the two atria in a developing fetus, allowing blood to bypass the lungs
Ductus Arteriosis
A duct that allows blood to travel from the pulmonary artery to the aorta in developing fetuses
After birth, turns into the ligamentum arteriosum
