Answer:
a. exercise
it is associated with less or lack of physical activity.
Answer:
d. sensory input from receptors in joints, neural input from the motor cortex, and other factors is the correct answer
Explanation:
- sensory input from receptors in joints, neural input from the motor cortex, and other factors stimulates increased respiration at the beginning of exercise.
- As we do exercise our muscles gets active, it produces lactic acid that enters the blood and hydrogen ions are a release that reduces the pH due to a decrease in the pH stimulates the sensory receptors to carry nerve impulses to respiratory muscles and this increase respiration at the beginning of the exercise.
- In medual the respiratory center is stimulated by increasing the carbon dioxide concentration.
a I'm pretty sure, because it wouldn't be longer I don't think I hope this helped
Answer:
The heart is a cone-shaped muscular organ located within the THORAX
. Its apex rests on the DIAPHRAGM , and its base is at the level
of the SECOND rib. The coronary artenes that nourish the
myocardium arise from the AORTA. The coronary sinus empties
into the RIGHT ATRIUM . Relative to the roles of the heart chambers, the
ATRIA are receiving chambers, whereas the VENTRICLES are
discharging chambers. The membrane that lines the heart and
also forms the valve ſaps is called the ENDOCARDIUM , The outermost
layer of the heart is called the EPICARDIUM . The fluid that fills the
pericardial sac acts to decrease FRICTION during heart activity.
The heart muscle, or myocardium, is composed of a special-
ized type of muscle tissue called CARDIAC MUSCLE
