Answer:
Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Explanation:
Inotropism is a health science term to refer to the contraction capacity of the cardiac (myocardial) muscles. Inotropic action influences contractile force, velocity of myocardial pressure development and ejection velocity.
- Negative inotropic effect means contraction force decreases or decreases cardiac output
- Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Positive chronotropic action increases
- heart rate -
tachycardia;
- cardiac contraction force, both atrio and ventricles);
- conduction velocity in the atrioventricular node.
Answer:
Yes, both the heart and arteries contract to pump blood.
Answer/Explanation:
Cotton is a natural fiber. Cotton is grown from a shrub which is a plant. Any type of fiber derived by plants, animals, and other geological forms of materials.
Linen a natural cellulosic fiber because it reacts with other substances because of certain chemical properties
So, both cotton and linen are natural fibers.
Acetate fibers are a mixture of synthetic, natural, and artificial fibres.
