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.
Answer: Ideally, the average heartbeat per minute of an individual is 80 beats per minute.
So if an individual heart's does 80 beats per minutes, then in one hour, that'd be 80 multiplied by 60 minutes, that'd be 4800 beats per hour. In a day, we have approximately 24 hours. Therefore, the total number of heart beat in a day will be 24 multiplied by 4800 which is 115200 heart beats in a day.
Answer:
Whey protein
Explanation:
Whey makes up 20% of the protein found in milk, but it's the superior protein for muscle building because it's absorbed quickly and causes a large and fast spike in blood amino-acid levels
