1)     What is the mainactivity of the colon?

1. Reabsorbing water from the guts into the circulatorysystem

1. Absorbing water from the circulatory system to excrete from thebody

1. Absorbing cellulose and glucose into the circulatorysystem

1. Absorbing amino acids and cellulose into the circulatorysystem

1. Killing off bacteria on the digested food

2)     Which of the followingis important in inflammation?

1. Contraction of actin, myosin, and thrombosthenin

1. Increased permeability of capillaries

1. Activation of platelets

1. Antibody activation

1. Superoxide and hydrogen peroxide

3)     When oxygen-rich bloodpasses through a capillary bed in poorly-oxygenated tissue, whathappens?

1. Hemoglobin delivers carbon dioxide to the tissue and picks upoxygen waste

1. Hemoglobin changes shape and much of the oxygen unbinds fromthe hemoglobin

1. Hemoglobin leaves the capillary and enters the tissue todeliver oxygen

1. Hemoglobin enters the capillary to carry carbon dioxide awayfrom the tissue

1. Hemoglobin changes shape and most of the carbon dioxide unbindsfrom the hemoglobin

4)     If a person with type-Oblood (the host) receives blood from a type-A donor, what are theconsequences?

1. There is no clotting because there are no antigens on thedonor’s type-A blood

1. Both A and B are true

1. The type-A donor blood clots because of the anti-B antibodiesin the host’s body

1. The type-A donor blood clots because of the anti-A antibodiesin the host’s body

1. There is no clotting because there are no antibodies in thehost’s type-O blood

5)     Which of the followingstatements best explains how the amount of water inside alveoliremains small?

1. The lymphatic system drains fluids from the alveoli

1. There are large amounts of proteins in the water inside thealveoli, which dilutes the water

1. There are large amounts of proteins in the interstitium,causing water to leave alveoli via osmosis

1. The fluid in the alveoli is passed into the esophagus

1. The question is wrong; the alveoli have large amounts of waterin them

6)     Which of the followingstatements about hydrochloric acid in the stomach isFALSE?

1. Begins the process of breaking down fats

1. Kills many pathogens that enter the stomach

1. It is responsible for activating pepsinogen into pepsin

1. Its production results in an increase in bicarbonate in theblood

1. Denatures proteins in the stomach

7)     A protein designed toattach to one kind of invading structure (protein, carbohydrate, orother structure or chemical that identifies the invader)is:

1. Lymphocyte

1. Rh factor

1. Antibody

1. Antigen

1. Lysosome

8)     Which of the followingstatements about T-lymphocytes is true?

1. They are responsible for manufacturing antibodies

1. Some kinds of T-lymphocytes bind to invaders, puncture them,and poison them

1. They are manufactured in the bone marrow

1. Each T-lymphocyte can react to dozens of differentantigens

1. They are related to humoral immunity, and not cell-mediatedimmunity

9)     When an action potentialis inhibited, which of the following statements describes thevoltage change?

1. Neurotransmitters are not produced in adequate amounts to carryon an action potential

1. Sodium ions are drawn into the axon and not released

1. Too much neurotransmitter is produced, causing the actionpotential to damage the axon

1. A greater voltage change is required because the restingvoltage is unusually negative

1. A smaller voltage change is required because the restingvoltage is close to zero

10)   Which of the following type ofwhite blood cells (leukocytes) moves via amoeboidlocomotion?

1. Erythrocytes

1. Lymphocyte

1. Basophils

1. Platelets

1. Macrophages

11)   When a person sees a car driving onthe road, and simultaneously hears the motor, the two sensoryinputs can be combined to form a more complete understanding of thesituation. This is an example of:

1. Afferent and efferent interaction

1. Chemosensitivity

1. Partial pressure

1. Integrative function

1. Facilitation

12)   During exercise, the blood flow tothe lungs increases by:

1. Decreased pressure in the pulmonary arteries

1. Greater pressure from the left ventricle of the heart

1. Greater number of open capillaries

1. More rapid contractions of the diaphragm

1. Slow, strong contraction of the diaphragm
