Congestive heart failure refers to which of the following? cardiac injury resulting from repeated myocardial infarctions right-heart failure resulting from lung disease sudden cardiac death peripheral edema and dilated neck veins failure of the heart to pump effectively

failure of the heart to pump effectively

Explanation:

The congestive heart failure is a chronic medical condition which affects the blood pumping power of the heart muscles. This results in heart failure. In this condition the fluid builds up around the heart which cannot be efficiently pump out by the heart.

The symptoms includes the fatigue, rapid heartbeat, swollen legs, shortness of breath and other problems.

The treatment associated with this medical condition includes the consumption of less salt, and limiting the fluid intake. In some cases the pacemaker is implanted to recover the pumping activity of the heart muscles.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
