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: See explanation
Explanation:
• Stability: this is defined as the ability of a certain body to go back to its original position or equilibrium when such body is displaced.
• Maximum Effort: This is the use of maximum force towards accomplishing a particular objective e.g lifting of weight.
• Maximum Velocity: Thus is the maximum speed that a certain body uses to move in a particular direction. We should note that when there's maximum speed, there's acceleration is zero.
• Impluse: It is the effect of a force that acts over time.
• Reaction:
• Torque: It is the rate of change that occurs in the angular momentum of a certain object.
• Angular Momentum: It measures the rotational momentum that occurs in a system.
