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.
When using a traditional wooden ramrod, the safety consideration that must be in mind is that the traditional wooden ramrods are <span>heavier than modern composite ramrods and this is the reason why it is more difficult to operate with them. Safety rules must be followed in order to prevent injuries.</span>
Children's rights according to the constitution of the United States of America, are the human rights of children with particular attention to the rights of special protection and care afforded to minors.The 1989 Convention on the Rights of the Child (CRC) defines a child as "any human being below the age of eighteen years, unless under the law applicable to the child, majority is attained earlier." Children's rights includes their right to "association with both parents, human identity as well as the basic needs for physical protection, food, universal state-paid education, health care, and criminal laws appropriate for the age and development of the child, equal protection of the child's civil rights, and freedom from discrimination on the basis of the child's race, gender, sexual orientation, gender identity, national origin, religion, disability, color, ethnicity, or other characteristics." Which means that any child, indiscriminately of how many deserves the basic right of "association with both parents, human identity as well as the basic needs for physical protection" Removing one or more children from their homes because of their number would severely violate their human rights.
