The respiratory centers are activated by impulses from ___ located in the ____ and ____, from stretch and irritant receptors in the ___ and from receptors in muscles and joints
|
chemoreceptors, aortic arch, carotid arteries, lungs
|
|
The respiratory centers are activated by impulses from chemoreceptors located in the aortic arch and carotid arteries from what two things?
|
from stretch and irritant receptors in the lungs and from
receptors in muscles and joints |
|
_____ refers to the force of blood against arterial walls
|
Blood Pressure
|
|
The highest blood pressure is what?
|
Systolic Pressure
|
|
When Maximum blood pressure is exerted on the walls of arteries when the left ventricle of the heart pushes blood through the aortic valve into the aorta
|
is the beginning of systole
|
|
The lowest pressure present on the arterial walls is the what?
|
Diastolic blood pressure
|
|
Name five factors that effect body temperature
|
circadian rhythms, age, gender, stress, and environmental temperatures
|
|
Events that recur at 24-hour intervals called what?
|
Circadian rhythm
|
|

|
very young and very old
|
|
When exposed to extreme cold without adequate protection what may occur?
|
Hypothermia
|
|
Extreme heat for long periods of time may cause what?
|
Hyperthermia
|
|
____ attempt to maintain a sufficient amount of blood to the cells at all times
|
Compensatory mechanisms
|
|
When stroke volume decreases. such as when blood volume decreases from hmorrhage, the heart rate does what?
|
increases to maintain the same cardiac output
|
|
Heart rate is also altered by what three things?
|
pain, emotions, and medications
|
|
What is stroke volume?
|
amount of blood coming out of the left ventricle
|
|
Name 7 factors that affect respiratory rate
|
excercise, medications, trauma, infection, pain, heart disease, and emotions
|
|
Name 9 Factors that affect blood pressure?
|
Age, circadian rhythm, gender, food intake, excercise, emotions, body position, race and drugs/meds
|
|
How does age affect blood pressure?
|
older adults have decreased elasticity of the arteries, which increases peripheral resistance and therefore increases blood pressure
|
|
How does circadian rhythm affect blood pressure?
|
normal flucuations during the day. Blood pressure is usually lowest on rising
|
|
How does Race affect Blood pressure?
|
Hypertension is more prevalent in African American men and women
|
|
How does drugs/meds affect Blood pressure?
|
oral contraceptives cause a mild increase in BP
|
|
How does gender affect blood pressure?
|
woman usually have lower BP than men of the same age until menopause
|
|
How does food intake affect blood pressure?
|
BP increases after eating food
|
|
How does exercise affect BP?
|
Systolic BP rises during periods of exercise
|
|
How does emotions affect BP?
|
generally causes the BP to rise
|
|
How does body position affect BP?
|
BP lower when prone or supine than when standing or sitting
|
|
