What is systole? The sinoatrial artery acts as the natural pacemaker that sends an impulse. This impulse causes contraction of the atria and forces blood into the ventricles. This impulse then transfers to the atrioventricular node and His-Purkinje network. This transfer of the impulse causes ventricular contraction. The ventricular contraction pumps blood to the aorta and pulmonary artery. Then, the ventricles relax. This relaxation of the ventricles causes the heart chambers to fill with blood. The arterial blood pressure is at its maximum during contraction. The pressure is at its minimum during relaxation.

Answers

Answer 1

Answer: The ventricular contraction pumps blood to the aorta and pulmonary artery.

Explanation:

The blood pressure of the body increases in this process through arteries are the blood is circulated to all the parts of the human body. After pumping out blood the ventricles relax and again fill with blood. This is called ventricular diastole.

Hope this helps✌️

The hormone that is in most of the steroids abused by athletes is testosterone. Therefore, the correct option is A.

The main hormone present in most of the drugs athletes abuse is testosterone.

Anabolic steroids, often referred to as synthetic variants of testosterone, are abused by athletes to improve their physical strength and muscle development.

These drugs have the ability to increase stamina, strength and muscle mass. However, their use can lead to a variety of negative consequences, such as cardiovascular problems, liver damage, hormone imbalances, hostility, and psychological difficulties.

Therefore, the correct option is A.
