| It is one of the three major body fluids (interstitial and intracellular fluids are the other two), when separated from “whole blood,” is a clear straw-colored fluid that consists of about 90% water and 10% solutes. | Plasma |
| The granules in these cells are small and numerous and tend to give the cytoplasm a coarse appearance and consists about 65% of the total WBC count in a normal blood sample. | Neutrophil |
| ______________________the ability to contract or shorten, allows muscle tissue to pull on bones and thus produce body movement. | Contractility |
| ______________are bundles of very fine cytoskeletal filaments that extend lengthwise along a skeletal muscle fiber and al-most fill the sarcoplasm. | Myofibrils |
| _____________the segment that runs the entire length of the thick filaments (also called anisotropic band) | A Band |
| _______________________________is a type of connection called a synapse and is characterized by a narrow gap, or synaptic cleft, across which neurotransmitter molecules transmit signals. | Neuromuscular Junction (NMJ) |
| ______________________ is a subdivision of the nervous system that regulates involuntary effectors. | Autonomic Nervous System (ANS) |
| The ANS has two efferent divisions: ___________________________ and the _________________________________ | sympathetic division parasympathetic division. |
| The ______________________ is the “intestinal nervous system” that is made up of a complex network of nerve plexuses buried between layers of the intestinal (gut) wall. | Enteric Nervous System (ENS) |
| ____________________ hormone acts on bone and kidney cells by increasing the release of calcium into the blood. The bone cells are especially affected, causing less new bone to be formed and more old bone to be dissolved, yielding calcium and phosphate. | parathyroid |
| ____________ a natural constituent of blood, acts as an antithrombin. | Heparin |
| The heart has its own special covering, a multilayered sac called the ______________ | Pericardium |
| The bulk of the heart wall is the thick, contractile, middle layer of specially constructed and arranged cardiac muscle cells called the _______________________ | myocardium |
| The _____________ valves of the heart consist of pocketlike flaps (leaflets) extending inward from the lining of the trunk of the pulmonary artery and aorta. | semilunar (SL) |
| The ____________ acts as the heart’s pacemaker and is part of the heart’s own conduction system. | SA node |
| ________________ is the amount of blood that flows out of a ventricle of the heart per unit of time. | Cardiac output (CO) |
