Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.

Explanation:
Answer: HDLs are antiatherogenic lipoproteins....
Explanation:
The anti-atherogenic effect of HDL occurs, above all, because of its properties to carry lipids, mainly cholesterol esters from peripheral tissues to the liver, which is known as reverse cholesterol transport(RCT). However, other protective actions of HDL, in addition to RCT, have been described in several experimental models and epidemiological studies. These actions include antioxidant protection, mediation of cholesterol efflux, inhibition of the expression of cell adhesion, leukocyte activation, regulation of blood coagulation and platelet activity.
