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.
  2. This is the mass of tissue from the sternum to the vertebral column between the lungs. => mediastinum.
  3. this is the layer that protects the heart. ⇨ epicardium.
  4. to which side of the body is the apex pointed? ⇨ to the left.
  5. which of the following consists of inelastic dense irregular connective tissue? ⇨ fibrous pericardium.
  6. this is used to reduce the friction between membranes of the heart. ⇨ pericardial (serous) fluid.
  7. this consists of mesothelium and connective tiessue. ⇨ epicardium.
  8. which layer consists of cardiac muscle tissue? ⇨ myocardium.
  9. this is used to increase the capacity of the atrium. ⇨ auricle.
  10. this marks the boundary between the ventricles. ⇨ anterior and posterior interventricular sulcus.
  11. these extend into the auricle ⇨ pectinate muscles.
  12. through which structure does blood pass from the right atrium to the right ventricle.

⇨ tricuspid valve.

  1. what types of tissue comprise the valves of the heart? ⇨ dense irregular connective tissue.
  2. from the left ventricle, where does blood pass? ⇨ aortic semilunar valve.
  3. in a fetus, this structure temporarily shunts blood from the pulmonary trunk into the aorta. ⇨ ductus arteriosus.
  4. as each ventricle contracts, where does blood move? ⇨ into an artery.
  5. as each atrium contracts, where does blood move? ⇨ through an atrioventricular valve.
  6. which of the below valves prevents blood from flowing back from the lungs? ⇨ pulmonary valve
  7. in this disorder the aortic valve is narrowed. ⇨ aortic stenosis.
  8. this heart structure carries deoxygenated blood. ⇨ left atrium and ventricle.
  9. this vessel distributes oxygenated blood to the myocardium. ⇨ coronary artery.
  10. cardiac muscle fibers electrically connect to neighboring fibers by

⇨ vagus nerve.

  1. which of the below reduces heart rate? ⇨ increased potassium levels.
  2. this part of the brain regulates heart rate. ⇨ medulla oblongata.
  3. this elctrical event represents repolarization of the ventricle. ⇨ t wave.
  4. which of the below factors would increase stroke volume? ⇨ increased pre load, decreased after load, increased contractility.
  5. this electrical event triggers contraction of the atria. ⇨ p wave.
  6. which of the following is the blood vessel that distributes blood to organs? ⇨ arteries.
  7. this is a blood vessel that conveys blood from the tissues back to the heart. ⇨ vein.
  8. which artery wall is responsible for vasoconstriction? ⇨ tunica media.
  9. this layer of the artery is composed mainly of elastic and collagen fibers. ⇨ tunica externa.
  1. when an artery or arteriole is damaged, its smooth muscle contracts producing ⇨ a vascular spasm.
  2. Elastic arteries function as a ⇨ pressure reservoir.
  3. These vessels make up the largest blood reservoir. ⇨ veins and venules.
  4. This vessel plays a key role in regulating blood flow into capillaries. ⇨ arterioles.
  5. Which of the below is not found in arteries but is found in veins? ⇨ valves.
  6. capillaries are also known as ⇨ exchange vessels.
  7. which of the below is the most important capillary excahnge method? ⇨ diffusion.
  8. these control the flow of blood through a capillary bed. ⇨ precapillary sphincter.
  9. continuous capillaries can be found in the following tissues. ⇨ skeletal muscle, smooth muscel connective tissue lungs, all the above.
  10. the alternate route of blood flow to a body part through an anastomosis is called ⇨ collateral circulation.
  11. the largest factor that promotes reabsorption of fluids, into blood, from the intersitial flud is => blood osmotic pressure.
  12. the pressure driven movement of fluids and solutes from blood into interstitial flue is called => filtration.
  13. this is the volumeof blood that flows through any tissue in a given time period.

=> contract more forcefully when stretched.

  1. what do these chemicals have in common: potassium, hydrogen ions, laactic acid, nitric oxide, and adenosine. => they are all potent vasodilators.
  2. where can pulse not be felt? => capillaries.
  3. this pressure provides infomration about the condition of the cardiovascular system such as atherosclerosis and patent ductus arteriosus. ⇨ pulse pressure.
  4. this type of shock is due to decreased blood volume. ⇨ hypovolemic.
  5. what do the following have in common : superficial temporal artery, bracial artery and dorsal artery of the foot. => they are all pulse points.
  6. which of the following is not a response to hypovolemic shock? ⇨ release of vasoconstrictors.
  7. all the veins of the systemic circulation drain into the ⇨ superior and inrerior vena cava and coronary sinu.
  8. the pulmonary trunk divides into => right and left pulmonary arteries.
  9. in fetal circulation what is teh opening between the right and left atria called? ⇨ foramen ovale.
  10. which of the below vessels is a pulse point at the wrist? ⇨ radial artery.
  11. which of the below vessels supplies blood to the intestines?

⇨ mesenteric artery.

  1. which of the below vessels supplies blood to the kidney? ⇨ renal artery.
  2. below vessels drains blood from the lower leg? ⇨ tibial vein.
  3. bessel that drains blood from the head and neck? ⇨ jugular bein.
  4. vessel drains blood from the lower body to the right atrium? ⇨ inferior vena cava.
  5. after birth when the umbilical cord is cut what do the umbilical arteries fill with? ⇨ connective tissue. Cell Structure And Its Function

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.
