Biology: QUIZ 1: DIGESTIVE SYSTEM

Hypertension is a condition involving: - the back-up of lymph causing tissue swelling - the inability to form clots when cut - the adverse reaction of a mother's body to an unborn - body with Rh + blood - high blood pressure within the arteries of the body

- high blood pressure within the arteries of the body

Alveoli are structures that are: - important in digestion within the stomach - used in the production of urine by the kidneys - important in respiration within the lungs - within the red bone marrow producing leukocytes

- important in respiration within the lungs

The cellular component of the blood that is involved in the body's defenses is called______________, and the cellular component that contains hemoglobin is called______________.

- leukocytes - erythrocytes

The function of the nephron is to: - regulate the rate of the heart during exercise - produce urine by filtering blood - reabsorb water from the feces within the rectum - produce insulin to regulate blood sugar

- produce urine by filtering blood

The purpose of the left ventricle is to: - pump blood to the upper and lower body - receive blood coming back from the lungs - pump blood toward the lungs to be oxygenated - receive blood back from the upper and lower body

- pump blood to the upper and lower body

Which blood vessels carry oxygenated blood? all arteries leaving the heart the arteries carrying blood to the body the arteries carrying blood to the lungs the pulmonary arteries the veins leaving the lungs the aorta

- the arteries carrying blood to the body - the veins leaving the lungs - the aorta

Acceptable blood pressure for a human being is under___________.

140/90

The average heart rate value for a healthy adult is________________ beats/min.

70

Which gas will be absorbed by the erythrocytes to the exclusion of oxygen? - CO2 - CO - N2 - NO2

CO

All veins carry dark CO2-rich blood. True False

False

External respiration includes expelling CO2 from cells in the body. T or F

False

Food moves from the mouth to the stomach through a long tube called the trachea. T or F

False

The diaphragm muscles must contract in order to force air out of the lungs (exhale). True False

False

The lungs contain elastic muscle tissue to permit inhalation. T or F

False

Which organ produces bile? - liver - pancreas - gall bladder - kidneys

Liver

Antibodies are: - germ fighting blood cells - uni-cellular organisms in the blood - proteins - none of the above

Proteins

The clotting of blood includes all of the following materials except: - prothrombin - Rh factor - calcium - fibrinogen

Rh factor

The breakdown of food into molecules small enough to enter the blood stream is primarily accomplished in the: - stomach - small intestine - large intestine - liver

Small intestine

The waste product eliminated by the lungs is carbon dioxide. T or F

True

What is found in the kidney pelvis? - water and minerals - replenished blood - unfiltered blood - urine

Urine

The trachea divides into__________ tubes.

bronchial

A major cause of emphysema as stated in the text is: - viral infections - cigarette smoking - coal mining - vitamin deficiency

cigarette smoking

The lower pressure between heart contractions is called___________.

diastolic pressure

The pigment in the red blood cells that carries oxygen is called__________________.

hemoglobin

The vocal cords which make the sounds that enable us to speak are contained within the: - bronchi - larynx - diaphragm - trachea

larynx

When foreign materials like bacteria enter the body, certain types of white blood cells eat or engulf these particles by a process known as________________.

phagocytosis

A, B, AB, and O blood groups are distinguished by: - the hemoglobin count - a Rh factor - the presence or absence of several plasma proteins - proteins on the erythrocytes

proteins on the erythrocytes

The upper pressure in the arteries when the heart is contracting is called______________.

systolic pressure

The exchange of gases for internal cellular respiration is accomplished by: - the respiratory system - the circulatory system - the excretory system - internal reactions within each cell

the circulatory system

Two basic processes exist in the kidney, filtration and reabsorption. Reabsorption occurs in which of the following kidney structures? - glomerulus - pelvis - Bowman's capsule - tubules

tubules
