Before surgery, the surgical procedure and postoperative care were discussed with Mr. Peterson and his wife. As part of this teaching, the Petersons were taught that coronary artery bypass graft (CABG) surgery was being done to:

a. cure coronary artery disease
b. reopen blocked coronary arteries
c. improve myocardial blood flow

c.improve myocardial blood flow

Explanation

The surgery improves myocardial blood flow bypassing coronary vessels that is blocked or narrowed, during surgery a part is cut or grafted from the internal mammary artery or radial artery and then attached to aorta and use to create a new connection tissues and pathway tissue perfusion is then established through this which is the ability of fluid or blood to flow again.

The surgery help to create passage of flow for blood in the myocardial

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
