TEAS practice test (ATI)Which of the following facilitates to prevent pathogens from invading the body?
A) histamines
b)mucus
c)t-cells
d)macrophages - ANSmucus, pores and skin, secretion (first step).
A bacteria mobile enters the body via a reduce inside the pores and skin. Which of the following
describes the immune response that would occur next?
A) cytotoxic t-cells
b)helper t-cells are activated
c)histamines are launched
d) antigens are released - ANShistamines (inflammatory response) are released
Which of the subsequent forms of cells produce antibodies?
A) T-cell
b)plasma-cells
c)memory cells
d)macrophages - ANSplasma-cells (The helper T cell induces
the B mobile to multiply hastily into secretory cells referred to as "plasma cells." These plasma
cells will then produce huge quantities of an antibody which could bind the antigen.)
which of the following fine describes the motive of a vaccine?
A.)To produce extra inflammatory responses inclusive of the release of histamines
B.)To exercise passive immunity
C.)To produce antibodies in case of future contamination
D.)To boom macrophage manufacturing - ANSto produce antibodies in case of future infection.
(Vaccinations introduce antigens, that are weakened or killed, to elicit an immune reaction.)
Which of the following elements of the male genitourinary system also transports sperm?
A. Ureter
B. Urethra
C. Uterus
D. Urinary bladder - ANSurethra (In adult males, the urethra passes through the penis and also
carries sperm. Females have a miles shorter urethra)
Which of the following waste products from digestion does the kidney put off?
A. Nitrogen
B. Sodium chloride
C. Protein
,D. Carbon - ANSnitrogen nitrogenous waste from protein digestion is toxic and should be
eliminated as it will form ammonia.
Which of the following nice describes the final results if the kidneys stopped functioning?
A. Blood would growth its carbon dioxide concentration.
B. Blood would fill with waste and the human frame could now not be able to preserve
homeostasis.
C. The kidneys would fill with urine.
D. The frequency in which a human excretes urine would increase. - ANSblood would fill with
waste and the human frame would no longer be capable of hold homeostasis.
Which of the following structures is the functional unit of the kidney?
A. Renal capillaries
B. Glomerulus
C. Nephron
D. Cortex - ANSnephron (The useful unit of the kidney is the nephron.)
In to a few sentences, give an explanation for the purpose of blood strain inside the kidney. -
ANSThe stress of the blood helps the glomerulus
clear out wastes and return crucial nutrients thru the renal vein to the blood. Nephrons are a
system of microscopic tubes that use
diverse stress levels to get rid of wastes and reabsorb critical molecules and water.
Which of the subsequent lists the primary components of the coronary heart?
A. Blood cells
B. Muscle tissue break up into chambers
C. Muscle tissue split into 4 chambers
D. Four ventricles - ANSmuscle tissue split into 4 chambers
Which of the following blood components is answerable for transporting oxygen?
A. Red blood cells
B. Plasma
C. Dissolved gases
D. Leukocytes - ANSRed blood cells ( RBC incorporate hemoglobin and shipping oxygen from
the lungs to the rest of the frame.)
Which of the subsequent chambers pumps blood towards the lungs?
A. Left atrium
B. Right atrium
C. Left ventricle
D. Right ventricle - ANSRV. (The proper ventricle pumps the blood towards the lungs, where it
picks up oxygen and loses carbon dioxide.)
Which of the subsequent statements high-quality describes the feature of veins?
, A. Veins bring deoxygenated blood.
B. Veins bring oxygenated blood.
C. Veins carry blood returned to the coronary heart.
D. Veins convey blood far from the heart. - ANS(C) Then, the oxygenated blood
returns to the coronary heart thru veins.
In to 3 sentences, describe chambers of the coronary heart that have thicker walls. Why could
those chambers be thicker? - ANSright and left ventricles became thick-walled due to the fact
they pump blood toward the whole frame which needs greater power then pumping blood into
the coronary heart itself.
Which of the subsequent describes the characteristic of the ribosome?
A. Protein synthesis
b. Energy manufacturing
c. Cell movement
d. Storage of molecules - ANSprotein synthesis
Because muscle cells require massive quantities of electricity to characteristic efficaciously,
which organelles might
be standard in those forms of cells?
A. Ribosomes
b. Mitochondria
c. Cytoskeleton
d. Cell membrane - ANSmitochondria (Skeletal muscle cells contain high numbers of
MITOCHONDRIA due to the energy needed for movement.)
Which of the following organelles is accountable for storing genetic records?
A. Nucleus
b. Ribosomes
c. Cell membrane
d. Lysosomes - ANSnucleus ( nucleus holds all genetic records including DNA, and conducts
the constructing of ribosomes)
In the human body, which of the subsequent organs is in a advanced position to the lungs?
A. Stomach
b. Brain
c. Spleen
d. Heart - ANSbrain
In two to 3 sentences, describe the part of the arm that is maximum distal to the shoulder of the
