Lab 10: Circulatory System Flashcards
Red blood cells. Transport oxygen to and carbon dioxide from the tissues.
Erythrocytes
White blood cells
Leukocytes
The nucleus of these granulocytes stains deeply and exhibits multiple lobes. These WBCs destroy bacteria.
Neutrophils
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.
Eosinophils
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.
Basophils
The category of WBCs lacking membrane bound granules.
Agranulocytes
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.
Lymphocytes
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.
Monocytes
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.
Right atrium
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.
Right venticle
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.
Pulmonary arteries
Carry oxgenated blood from the lungs to the left atrium.
Pulmonary veins.
