What would cause a decrease in red blood cells?
inadequate intake of iron
what is responsible for the regulation of PH in the body?
urinary system
what increases the basal metabolic rate in adults?
stress
what effects does asthma have on the lungs?
inflames and narrows the bronchioles and airways while increasing mucus production
what controls the bodys immune response?
white blood cells (lymphocytes)
what controls the rate and depth perception in a normal adult?
chemoreceptors in response to the acid base oxygen status
the principal function of blood flow to the cardiac system?
to provide oxygen and remove carbon dioxide and waste product
what does the parasympathetic nervous system do?
It decreases HR and increases intestional gland activity also relaxes sphincter muscles in the gastro intestinal track (rest and digest)
Human BP increases signals are sent to the brain slowing down the heart and helping the BP to return to a normal is an example of what?
Negative feedback loop
how is oxygen and carbon dioxide exchanged through red blood cells?
Diffusion
How do electrolytes exchange between interstitial fluid and external interstitial fluid?
osmosis
How does your brain cells differ from other cells in the body?
Brain cells do not store glucose and glycogen
Gas exchange in the lungs occurs where?
in the alveoli
what controls the firing of the SA node to trigger the spark of the cardiac cycle?
Autonomic nervous system
Chronic hypertension would cause what changes in the blood vessels?
Damage to the arterioles resulting in the increased blood flow through blood vessels.
the bodys ability to correct an excess or deficit of a metabolic acid depends on normal function of what system?
Renal system
when air enters the lungs it?
expansion, the pressure inside the lungs becomes negative compared to atmospheric pressure causing air to enter the lungs
air changes what sensation?
hearing/vision or increase in sensation/ perception of temperature.
how are neurons different than other cells in the body?
communicate faster
a patient with gout present which of the following are their symptoms?
red, swollen feet
how does blood flow through the heart?
right atrium, right ventricle, pulmonary artery, lungs, left atrium, left ventricle, aorta, body
what are the three compartments in the body that stores water?
intracellular, extracellular, and interstitial
where does most food digestion and nutrient absorption occur?
small intestine
what regulates decision making, problem solving, control of purposeful behavior, consciousness and emotion?
frontal lobe
what is true about the transport of oxygen to the lungs?
a demand for more oxygen requires the increase in cellular metabolism.
what responds quickly to infectious agents?
Granulocytes
what controls heart rate?
SA nodes, medulla oblongata, PNS, SNS
what is hemoglobinj?
protein in red blood cells that carrys oxygen through the body.
what is an example of low hemoglobin count?
Anemia
what is hypertension?
abnormally high blood pressure 140/90 or greater
what would a normal BP reading show?
120/80 or slightly lower
what does the sympathetic nervous system do?
increases or accelerates the heart rate, constrict blood vessels and raises blood pressure
what does the autonomic nervous system do?
regulates the function of our internal organs such as the heart, intestines and the stomach
Brain functions of the cerebral cortex?
when judgement association and discrimination takes place
what does White blood cells do?
fight pathogens
difference between intercellular and intracellular?
inter- between of connecting cells
intra- inside or within a cell
what is positive feedback mechanism of the body?
when the output enhances the original stimulus such as the projection of oxytocin ( aid in childbirth)
what is negative feedback mechanism of the body?
when the output reduces or decreases the original effect on the stimulus. (insulin lowers high blood sugars)
what happens during an asthma attack?
muscles around the airways tightens and the lining becomes swollen and inflamed producing more mucus
endocrine system is largely responsible for?
Water electrolytes
Cellular metabolism transport across the membrane
Nutrient balance
Growth development
Reproduction & body defenses
