BIO 206 Exam Two
Lymph, Immune, Respiratory System
| Term | Definition |
|---|---|
| Alveoli | microscopic air sacs of the lungs |
| Antibody | a protein molecule that is released by plasma cell (a daughter cell of an activated B-lymphocyte) and that binds specifically to an antigen; an immunoglobulin |
| Antigen | a protein molecule that is released by plasma cell (a daughter cell of an activated B-lymphocyte) and that binds specifically to an antigen; an immunoglobulinApnea |
| Apnea | breathing cessation |
| Asthma | respiratory passageways narrowed bronchiolar spasms |
| B-cell | also called B- lymphocytes; oversee humoral activity; their descendants differentiate into antibody-producing plasma cells |
| Bronchi | one of the two large branches of the trachea that lead to the lungs |
| Bronchioles | smaller branching passageways inside the lungs |
| Cellular immunity | immunity conferred by activated T cells, which directly kill infected or cancerous body cells or cells of foreign grafts and release chemicals that regulate the immune system response. |
| Complement | group of bloodborne protein, which, when activated enhance the inflammatory and immune responses and mal lead to cell lysis. |
| Dead space volume | air in respiratory passages that does not contribute to gas exchange |
| Defensins | broad-spectrum antimicrobial peptide that is secreted from mucous membranes and skin |
| Emphysema | condition characterized by increased mucous production, which clogs respiratory passageways and promotes coughing |
| Epiglottis | elastic cartilage at the back of the throat closes off the larynx during swallowing |
| Glottis | lumen of larynx. Opening between the vocal cords in the larynx |
| Humoral immunity | immunity conferred by antibodies present in blood plasma and other body fluid |
| Hypercapnia | high carbon dioxide levels in the blood |
| Hyperventilation | an increase in the depth and rate of breathing that is in excess of the body’s need for removal of carbon dioxide |
| Hypoxia | chronic oxygen deficiency |
| Inflammation | a nonspecific defensive response of the body to tissue injury; includes dilation of blood vessels and an increase in vessel permeability; indicated by redness, heat, swelling, and pain |
| Interferon | proteins released from virus-infected cells that protect uninfected cells from viral take-over. Also inhibit some cancers |
| Larynx | cartilaginous organ located between the trachea and pharynx; voice box |
| Lymph | protein-containing fluid transported by lymphatic vessels |
| Lymph nodes | small lymphoid organ that filters lymph; contains macrophages and lymphocytes |
| Macrophages | protective cell type, phagocytizes tissue cells, bacteria, and other foreign debris. Presents antigens to T cells in the immune response |
| Memory cell | members of the T cell and B cell clones that provide for immunological memory |
| Nasal conchae | fleshy lobes in the nasal cavity, which increase its surface area. Three lobes: superior, middle, inferior |
| Natural killer cell | defensive cell (a typ of lymphocyte) that can kill cancer cells and virus-infected body cells before their adaptive immune system is activated |
| Opsonization | a pathogen that gets coated with complement proteins |
| Plasma cells | members of a B cell clone; effector B cells specialized to produce and release antibodies |
| Pleurae | two layers of serous membrane that line the thoracic cavity and cover the external surface of the lung |
| Respiration | the process involved in supplying the body with oxygen and disposing of carbon dioxide |
| Surfactant | secretion produced by certain cells of the alveoli that reduce the surface tension of water molecules, thus preventing the collapse of the alveoli after each expiration |
| T-cell | lymphocytes that mediate cellular immunity; include helper, cytotoxic, regulatory, and memory cells. Also called T lymphocytes. |
| Trachea | windpipe; cartilage-reinforced tube extending from larynx to bronchi |
| Vital capacity | the volume of air that can be expelled form the lungs by forcible expiration after the deepest inspiration; total exchangeable air |
