In the short-term response to hemorrhage, ________ occurs.

1 answer:

4 0

Sympathetic nervous system elevates blood pressure. Long term, decrease in capillary blood pressure recalls fluids from interstitial spaces. Aldosterone and ADH promote fluid retention. Increased thirst promotes water absorption across the digestive tract. Short term, Carotid and aortic reflexes move up cardiac output and peripheral vasoconstriction.

Describe the physiological events occurring in the heart muscle represented by each ECG component (the P wave, QRS complex, and

Sauron [17]

Explanation:

The P wave represents the atrial depolarization (sum of the right and left atriums) and the atrial contraction. In normal circumstances, the P wave is smooth and rounded (<2.5 mm) and no more than 0.12 seconds in duration. It's the first positive deflection (you can see this in the image I added)
QRS complex can include the Q wave, R wave, and S wave, but there are exceptions. It represents the electrical impulse through the ventricles causing the ventricular depolarization. Its amplitude is the largest because ventricles are the chambers with the largest mass in the heart and it has a duration of 0.06-0.10 seconds in adults.
The T wave is the positive deflection that follows the QRS complex, it represents the ventricular repolarization. It is slightly asymmetric (peak closer to its end). Normally this wave follows the QRS complex's direction, if this doesn't happen, it's reflecting a cardiac pathology.

Aliun [14]

The theory of natural selection was first expounded by Charles Darwin and today it is believed to be the main process that brings about evolution.

This process is defined as the process whereby organisms who better adapt to their environment tend to survive and produce more offspring.

Hence, according to this statement, option C is correct.

More organisms are born than can survive.
