CO
The clotting of blood includes all of the following materials except:
Rh factor
The trachea divides into -blank- tubes.
bronchial
A major cause of emphysema as stated in the text is:
cigarette smoking
The lower pressure between heart contractions is called
diastolic pressure
small intestine
digestion and absorption of food
The vocal cords which make the sounds that enable us to speak are contained within the:
larynx
tubules
reabsorption of needed materials by the kidney
pancreas
secretes digestive enzymes into the small intestine
salivary glands
secretion for digestion in mouth
The breakdown of food into molecules small enough to enter the blood stream is primarily accomplished in the:
small intestine
gall bladder
stores bile
pericardium
the sac around the heart
The waste product eliminated by the lungs is carbon dioxide.
true
Two basic processes exist in the kidney, filtration and reabsorption. Reabsorption occurs in which of the following kidney structures?
tubules
What is found in the kidney pelvis?
urine
Acceptable blood pressure for a human being is under
140/90
The average heart rate value for a healthy adult is -blank- beats/min.
70
All veins carry dark CO2-rich blood.
false
External respiration includes expelling CO2 from cells in the body.
false
Food moves from the mouth to the stomach through a long tube called the trachea.
false
The diaphragm muscles must contract in order to force air out of the lungs(exhale).
false
The lungs contain elastic muscle tissue to permit inhalation.
false
Bowman's capsule
filtration of wastes from the blood
vili
fingerlike projections that absorb nutrients
The pigment in the red blood cells that carries oxygen is called
hemoglobin
Hypertension is a condition involving:
high blood pressure within the arteries of body
stomach
hydrochloric acid to digest food
Alveoli are structures that are:
important in respiration within the lungs
larger intestine
intestinal flora
The cellular component of the blood that is involved in the body's defense is called -blank-, and the cellular component that contains hemoglobin is called -blank-
leukocytes erythrocytes
Which organ produces bile?
liver
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
The function of the nephron is to:
produce urine by filtering blood
Antibodies are:
proteins
A,B,AB, and O blood groups are distinguished by:
proteins on the erythrocytes
The purpose of the left ventricle is to:
pump blood to the upper and lower body
The upper pressure in the arteries when the heart is contracting is called
systolic pressure
Which blood vessels carry oxygenated blood?
the arteries carrying blood to the body the veins leaving the lungs the aorta
The exchange of gases for internal cellular respiration is accomplished by:
the circulatory system
