| Question | Answer |
|---|---|
| From which vessels do myocardial cells receive blood? | coronary arteries |
| After blood leaves the lungs and returns to the heart, it enters the | Left atrium |
| The type of membranous tissue that lines the heart and blood vessels is the | Endothelium |
| The free edges of the atrioventricular valves are anchored to the | papillary muscles |
| Which division of the autonomic nervous system sends fibers to the heart | Parasympathetic and sympathetic |
| In _____, blood moves from veins to other veins or arteries to other arteries without passing through an intervening capillary network | vascular anastomoses |
| Neutrophils are highly mobile and phagocytic. They migrate out of blood vessels and into tissue spaces. This process is called | Diapedesis |
| The internal iliac artery supplies blood to the | Pelvis |
| Mechanical devices that permit the flow of blood in one direction only are called | Valves |
| The _____ is(are) supplied with blood from the left subclavian artery. | head and upper extremities |
| Which sphincters function as regulatory valves that reduce the flow of blood through a network of capillaries when they contract and constrict the arterioles? | precapillary sphincters |
| The _____ drains much of the superficial leg and foot. | great saphenous vein |
| A glycoprotein hormone that is secreted to increase oxygen concentration in the tissues is | erythropoietin |
| Which of the following is not a formed element found in the blood? | plasma |
| All of the following are granulocytes except | Lymphocytes |
| The outermost layer of the larger blood vessels is the tunica | Adventitia |
| The brachiocephalic vein drains blood from the | head, neck, and upper extremity |
| Platelets play an important role in | blood clotting |
| Erythrocytes begin their maturation sequence in red bone marrow from nucleated cells known as: | hematopoietic stem cells |
| The bulk of the heart wall is the thick, contractile middle layer called the | myocardium |
| _____ is used to determine the volume percentage of red blood cells in whole blood | Hematocrit |
| Which layer of the larger blood vessels is made up of endothelium | Tunica intima |
| Which organ has several functions, including defense, hematopoiesis, red blood cell and platelet destruction, and blood reservoir? | spleen |
| The functions of the lymph nodes are | defense and hematopoiesis |
| Which antibody is synthesized by immature B cells and then inserted into their plasma membranes? | Immunoglobulin M |
| The movement of phagocytes from blood vessels to an inflammation site is called | Diapedesis |
| The primary organ of the lymphatic system is the | Thymus |
| _____ refers to a phenomenon in which the genetic characteristics common to a particular kind of organism provide defense against certain pathogens. | Species resistance |
| Which of these substances operate(s) immune mechanisms? | Sebum, mucus, enzymes, hydrochloric acid in gastric mucosa |
| Recognition of antigens by antibodies occurs when an | Antigen's epitopes fit into and bind to an antibody molecule's antigen-binding sites |
| Lymphatics in the villi of the small intestines are called | Lacteals |
| The presentation of an antigen by an antigen-presenting cell activates the T cell. The cell then divides repeatedly to form a clone of identical sensitized T cells that form | effector T cells and memory cells |
| Chemotaxis is the process by which a cell navigates toward the source of the chemotactic factor by way of | detecting and then moving toward higher concentrations of the factor |
| The _____ postulates that when an antigen enters the body, it selects the clone whose cells are committed to synthesizing its specific antibody and stimulates these cells to proliferate and to thereby produce more antibodies. | clonal selection theory |
| The body’s defense mechanisms can be organized into one of two major categories of immune mechanisms; these are | innate and adaptive immunity |
| Which of the following is a powerful poison that acts directly on any cell and quickly kills it? | Lymphotoxin |
| The roof of the nose is separated from the cranial cavity by a portion of the ethmoid bone called the | cribiform plate |
| Which organ consists largely of cartilages that are attached to one another and to surrounding structures by muscles or fibrous and elastic tissue components? | larynx |
| The vibrissae function as | filters |
| The microscopic cilia function to | move mucus toward the pharynx |
| The small leaf-shaped cartilage that projects upward behind the tongue and hyoid bone is the | epiglottis |
| The respiratory portion of the nasal passage is lined with a mucous membrane made up of _____ epithelium | pseudostratified columnar |
| The structures that deflect air as it passes through the nose are called: | Conchae |
| Paranasal sinuses are normally filled with: | air |
| The approximate length of the trachea, or windpipe, is _____ cm. | 11 |
| The fauces, one of the seven openings found in the pharynx, opens into the: | Oropharynx |
| Olfactory epithelium is found: | covering the superior turbinate. |
| The small openings in the cribriform plate function to: | allow branches of the olfactory nerve to enter the cranial cavity and reach the brain |
| The structure in the neck known as the “Adam’s apple” is the: | thyroid cartilage |
| The eustachian tube connects the middle ear with the: | nasopharynx. |
| In the right lung, the superior and middle lobes are separated by the: | horizontal fissure |
| The anatomical division of the pharynx that is located behind the mouth from the soft palate above to the level of the hyoid bone below is called the | Oropharynx |
| Which of the following is not a function of the respiratory system? | Distributes oxygen to cells |
| Which of the following is true of the cribriform plate? | It separates the nasal and cranial cavities |
| Which of the following is not lined with a ciliated mucous membrane? | vestibule |
| The largest of the paranasal sinuses is the: | maxillary. |
| Which of the following does not distribute air? | Alveolus |
