Flashcards in Lab 10: Circulatory System Deck (22):
1

Red blood cells. Transport oxygen to and carbon dioxide from the tissues.

Erythrocytes

2

White blood cells

Leukocytes

3

The nucleus of these granulocytes stains deeply and exhibits multiple lobes. These WBCs destroy bacteria.

Neutrophils

4

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

5

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

6

The category of WBCs lacking membrane bound granules.

Agranulocytes

7

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

8

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

9

2 large veins that enter the right atrium and carry unoxygenated blood from the superior and inferior body, respectively

Precava and Postcava

10

The first chamber of the heart and receives unoxygenated blood from the body.

Right atrium

11

Separates the right atrium and left ventricle. Prevents back flow into the atrium.

Tricuspid or right atrioventricular valve

12

The second chamber of the heart and pumps blood to lungs.

Right venticle

13

Separates the pulmonary trunk from the right ventricle and prevents back flow into the ventricle.

Pulmonary semilunar valve

14

Carry unoxygenated blood from the right ventricle to the lungs.

Pulmonary arteries

15

Carry oxgenated blood from the lungs to the left atrium.

Pulmonary veins.

16

Third chamber of the heart and receives oxygenated blood from the lungs

Left atrium

17

Separates the left atrium and ventricle. Prevents back flow into the atrium.

Bicuspid, mitral, or left atrioventricular valve

18

Fourth chamber of the heart and pumps oxygenated blood to the body.

Left ventricle

19

Separates the aortic arch from the left ventricle and prevents back flow into the ventricle.

Aortic semilunar valve

20

The largest elastic artery in the body and carries oxygenated blood to the body.

Aortic arch and aorta

21

The "heart strings" and the muscles that control the tricuspid and bicuspid valves.

Chordae tendonae and papillary muscles

22

The vessels located on and in the actual myocardium or heart muscle. They supply and drain the myocardium of blood, respectively.

Coronary arteries and veins
