the correct answer is <u>B. Unsaturated fat</u>
Answer:
a. QRS
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
The QRS complex represents the time necessary for the impulse to travel through the bundle of His, the bundle branches, and the Purkinje fibers to complete ventricular activation or contraction, known as ventricular depolarization. QRS is simply a combination of the Q-wave, R-wave and the S-wave which represents electrical impulses.
<span>In 2013 the suicide rate in the United States was 13 per 100,000 people, the highest recorded rate in 28 years. The U.S. suicide rate also rose 24%
over the 15 previous years (1999-2014), In 2009, suicide was the
seventh leading cause of death for males and the 16th leading cause of
death for females.</span>
Falso. For example, let's choose soccer. On the field, the coach can't tell the player to pass, to kick it to number 13, or anything like that. Some decisions can be made, like whose playing. But not all decisions are made by coaches. hope this helps! Please rate brainiest answer!
