SCIENCE TEAS TEST 6 1) Pulmonary artery transports deoxygenated blood pumped from the right ventricle of the heart to lungs while Pulmonary veins delivers oxygenated blood from lungs to left atrium. ... 1) This is the mass of tissue from the sternum to the vertebral column between the lungs. 2) this is the layer that protects the heart. 3) to which side of the body is the apex pointed? 4) which of the following consists of inelastic dense irregular connective tissue? 5) this is used to reduce the friction between membranes of the heart. 6) this consists of mesothelium and connective tiessue. 7) which layer consists of cardiac muscle tissue? 8) this is used to increase the capacity of the atrium. 9) this marks the boundary between the ventricles. 10) these extend into the auricle 11) through which structure does blood pass from the right atrium to the right ventricle. 12) what types of tissue comprise the valves of the heart? 13) from the left ventricle, where does blood pass? 14) in a fetus, this structure temporarily shunts blood from the pulmonary trunk into the aorta. 15) as each ventricle contracts, where does blood move? 16) as each atrium contracts, where does blood move? 17) which of the below valves prevents blood from flowing back from the lungs? 18) in this disorder the aortic valve is narrowed. 19) this heart structure carries deoxygenated blood. 20) this vessel distributes oxygenated blood to the myocardium. 21) cardiac muscle fibers electrically connect to neighboring fibers by 22) which of the following contains the largest amount of mitochondria? 23) this is a network of specialized cardiac muscle fibers that provide a path for each cycle of cardiac excitation to progress through the heart. 24) this is the correct sequence of structures that allows the normal sequence of excitation to progress through the heart. 25) by comparison, cardiac muscle cells have contraction plateau time than skeletal muscle cells. 26) this is the volume of blood ejected from the left ventricle into the aorta each minute. 27) this term refers to the period of time during a cardiac cycle when contraction occurs and blood pressure rises. 28) which of theses periods represents greatest cardiac output? 29) the second heart sound represents which of the below events? 30) this part of the heart can initiate a contraction and can set a constant heart raet of about 100 beats per minute. 31) simulation of this nerve reduces heart rate. 32) which of the below reduces heart rate? 33) this part of the brain regulates heart rate. 34) this elctrical event represents repolarization of the ventricle. 35) which of the below factors would increase stroke volume? 36) this electrical event triggers contraction of the atria. 37) which of the following is the blood vessel that distributes blood to organs? 38) this is a blood vessel that conveys blood from the tissues back to the heart. 39) which artery wall is responsible for vasoconstriction? 40) this layer of the artery is composed mainly of elastic and collagen fibers. 41) when an artery or arteriole is damaged, its smooth muscle contracts producing 42) Elastic arteries function as a 43) These vessels make up the largest blood reservoir. 44) This vessel plays a key role in regulating blood flow into capillaries. 45) Which of the below is not found in arteries but is found in veins? 46) capillaries are also known as 47) which of the below is the most important capillary excahnge method? 48) these control the flow of blood through a capillary bed. 49) continuous capillaries can be found in the following tissues. 50) the alternate route of blood flow to a body part through an anastomosis is called 51) the largest factor that promotes reabsorption of fluids, into blood, from the intersitial flud is 52) the pressure driven movement of fluids and solutes from blood into interstitial flue is called 53) this is the volumeof blood that flows through any tissue in a given time period. 54) blood flow depends on which of the following criteria? 55) which of the below would not increase blood pressure? 56) which of the below factors do not increase systemic vascular resistance? 57) this depends mostly on the ratie of rbc to plasma volume. 58) circulation time in a resting person is normally 1 min.the cardiovascular center is located 59) which of the below factors is most important in forcing blood flow through veins? 60) which of the below would be the response of the body as a result of decreased frequency of action potentials arising from the baroreceptors? 61) which of the following hormones would not cause an increase in blood pressure? 62) chemoreceptors in blood vessels measuring high levels of blood carbon dioxide would not cause which of the following. 63) the myogenic response make smooth muscle 64) what do these chemicals have in common: potassium, hydrogen ions, laactic acid, nitric oxide, and adenosine. 65) where can pulse not be felt? 66) this pressure provides infomration about the condition of the cardiovascular system such as atherosclerosis and patent ductus arteriosus. 67) this type of shock is due to decreased blood volume. 68) what do the following have in common : superficial temporal artery, bracial artery and dorsal artery of the foot. 69) which of the following is not a response to hypovolemic shock? 70) all the veins of the systemic circulation drain into the 71) the pulmonary trunk divides into 72) in fetal circulation what is teh opening between the right and left atria called? 73) which of the below vessels is a pulse point at the wrist? 74) which of the below vessels supplies blood to the intestines? 75) which of the below vessels supplies blood to the kidney? 76) below vessels drains blood from the lower leg? 77) bessel that drains blood from the head and neck? 78) vessel drains blood from the lower body to the right atrium? 79) after birth when the umbilical cord is cut what do the umbilical arteries fill with? Cell Structure And Its Function Cell Membrane In BOTH types of cells. Controls what goes in and out of the cell. Chloroplast In a PLANT CELL. Captures energy from sunlight. Uses energy to produce cell food, which is sugar. Process called photosynthesis. Cytoplasm In BOTH types of cells. Houses gel-like fluids that support cell organelles. Endoplasmic Reticulum In BOTH types of cells. Carries substances, like proteins, to various parts of the cell. Golgi Body/Complex In BOTH types of cells. Receives materials from endoplasmic reticulum, distributes materials. Large Vacuole In a PLANT CELL. Stores water, food, waste and more for a plant cell. Lysosome In an ANIMAL CELL. Contain chemicals that break down certain materials. Breaks down dead cells. Mitochondria In BOTH types of cells. Organelle that produce most of the cells energy, which is ATP. Nuclear Envelope In BOTH types of cells. Protects the Nucleus. Lets things in and out of the Nucleus. Nucleolus In BOTH types of cells. Makes Ribosomes. Nucleus In BOTH types of cells. Directs all cell actions, including reproduction. Ribosome In BOTH types of cells. Produces proteins. Small Vacuole In an ANIMAL CELL. Transport and stores materials, including waste. Cell Wall In a PLANT cell. Helps protect and support the cell. Gives a plant cell a shape. [Show More]
