Answer:
the rhythm of heart contractions.
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;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. 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.
Answer:
The given statement is false.
Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.
Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.
Thus the amount and type of precipitation in tropical and temperate rainforests are different.
