What is the function of structure A?to produce bileliverstomachchemical digestionThe esophagus pushes food down into the stomach using peristalsis.
10 Liver (F) – produces bile that goes to the SI Through which of these structures does food pass?Which organs are not part of the gastrovascular tract? How do they aid in digestion?Esophagus (A)Small intestine (D)Stomach (B)Liver (F) – produces bile that goes to the SIGall bladder (E) – stores bilePancreas (C) – releases pancreatic juice into SI
11 Describe the role of the small intestine in digestion. Where most chemical digestion occursWhere chemical digestion is completedLined with VILLI which absorb nutrients into the blood
12 Identify the labeled organs. A - Oral cavityB - EsophagusC – StomachD – PancreasE - Large intestineF - AppendixG - Small intestineH – Gall bladderI - Liver
13 Through what organs does food pass? (in order) Oral cavityEsophagusStomachSmall intestineLarge intestineRectumAnus2. In which structures does peristalsis occur?Esophagus, stomach, small intestine, large intestine, rectum
14 Bile – into small intestine Where excess water reabsorbed?2. What occurs in structure G?3. What does I produce? Where does it go?4. This is where chemical digestion begins.5. This is where chemical digestion ends.Large intestineVilli absorb nutrients into bloodBile – into small intestineOral cavitySmall intestine
15 Identify organs where there is no digestion occurring. EsophagusLiverSalivary glandsPancreasGlass bladder
16 Which part of the human blood: is the most numerous? contains a nucleus?is biconcave?is produced in the bone marrow?consists mainly of water?rbc’swbc’srbc’srbc’s, wbc’s, plateletsplasma
17 Identify structures X, Y, and Z. white blood cellYZred blood cellplateletIdentify structures X, Y, and Z.
18 Which activity is not a function of white blood cells in response to an invasion of the body by bacteria?engulfing these bacteriaproducing antibodies to act against this type of bacteriapreparing for future invasions of this type of bacteriaspeeding transmissions of nerve impulses to detect these bacteria
19 Which part of the human blood transports hormones and nutrients? plasmaplateletsred blood cellswhite blood cells
20 The breaking apart of platelets in the blood helps in the synthesis of hemoglobinformation of a clotrelease of antibodiesdeamination of amino acids
21 Cardiovascular diseases interfere most directly with the normal functioning of system?
22 Explain the difference between arteries and veins. Arteries carry blood AWAY from heart. Veins carry blood to the heart.Arteries are larger, more muscular and elastic than veins.Arteries carry blood under higher pressure than veins.Veins have valves to prevent the backflow of blood. Arteries do not have valves.
23 Explain what occurs in capillaries and why. The exchange or diffusion of substances into or out of the capillary.Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur.
24 The diagram represents a capillary near some cells. glucoseO2CO2O2glucoseglucoseO2CO2The diagram represents a capillary near some cells.1. Identify the substances diffusing out of the capillary and into cells.2. Identify the substances diffusing out of cells into the capillary.CO2O2glucose24
25 Blood normally flows from the capillaries directly into small arteriessmall veins3. lymph vessels4. heart atria
26 The movement of blood from the legs toward the heart is hindered by gravity. The effect of gravity is counteracted bysmooth muscle in the capillariescilia lining the blood vesselsvalves in the veinslymph nodes near major vessels
27 Which statement best describes arteries? They have thick walls and transport blood away from the heart.They have thick walls and transport blood toward the heart.They have thin walls and transport blood away from the heart.They have thin walls and transport blood toward the heart.
28 Identify the upper chambers of the heart. Identify the lower chambers of the heart.Identify the structures that separate the upper and lower chambers.Identify the wall that separates the right and left side of the heart.Right and left atriaRight and left ventriclesvalvesseptum

31 Identify the part of the heart being described. Chamber that receives oxygenated blood.Wall that separates the right and left side of the heart.Large artery that carries oxygenated blood to the rest of the body.Chamber that pumps out deoxygenated blood.Left atriumSeptumAortaRight ventricle
32 5. Chamber that receives deoxygenated blood. 6. Prevents the backflow of blood between atria and ventricles.7. Chamber that pumps out oxygenated blood.Right atriumValvesLeft ventricle
