Flashcards in Lab 10: Circulatory System Deck (22):
Red blood cells. Transport oxygen to and carbon dioxide from the tissues.
White blood cells
The nucleus of these granulocytes stains deeply and exhibits multiple lobes. These WBCs destroy bacteria.
The nucleus of these granulocytes usually has two darkly stained lubes connected by a thin strand. The cytoplasm contains large granules that stain reddish orange. These WBCs phagocytize antibody antigen complexes and attack some new parasitic worms.
The nucleus of these granulocytes exhibits two lobes which are difficult to see because of the large and dense blue stained granules. The granules aid in the inflammation process by releasing histamine.
The category of WBCs lacking membrane bound granules.
The nucleus is round and almost fills the cytoplasm. The nucleus stains dark blue to purple, and the cytoplasm is usually light blue . These agranulocytes are involved in specific disease resistance. B cells, T cells, and natural killer cells are types of these.
The nucleus is a kidney bean shape. The nucleus stains darkly and the abundant cytoplasm is a pale blue. These agranulocytes develop into phagocytic macrophages.
2 large veins that enter the right atrium and carry unoxygenated blood from the superior and inferior body, respectively
Precava and Postcava
The first chamber of the heart and receives unoxygenated blood from the body.
Separates the right atrium and left ventricle. Prevents back flow into the atrium.
Tricuspid or right atrioventricular valve
The second chamber of the heart and pumps blood to lungs.
Separates the pulmonary trunk from the right ventricle and prevents back flow into the ventricle.
Pulmonary semilunar valve
Carry unoxygenated blood from the right ventricle to the lungs.
Carry oxgenated blood from the lungs to the left atrium.
Third chamber of the heart and receives oxygenated blood from the lungs
Separates the left atrium and ventricle. Prevents back flow into the atrium.
Bicuspid, mitral, or left atrioventricular valve
Fourth chamber of the heart and pumps oxygenated blood to the body.
Separates the aortic arch from the left ventricle and prevents back flow into the ventricle.
Aortic semilunar valve
The largest elastic artery in the body and carries oxygenated blood to the body.
Aortic arch and aorta
The "heart strings" and the muscles that control the tricuspid and bicuspid valves.
Chordae tendonae and papillary muscles
