Answer: E. All of the above are correct/true.
Explanation:
The homeostasis is the process of maintenance of the internal environment of the body in constant and stable state as compared to the outer environment.
The homeostatic control mechanism has three interdependent components that are receptor, a control center, effector and sensor. For receptor it can be said that it is the sensing component of the body that monitors as well as responds to the changes in the environment. The receptor can be in the form of thermoreceptors, chemoreceptors and mechanoreceptors which have different associated functions.
The control center is the center which exhibit a feedback system that distinguishes the value of the system to the normal range for a particular stimulus. If the value deviates from the set point, then the control center is responsible for activating the effector.
The effector is a part of feedback system it causes a change and return the value to the normal range.
The sensor is also called as the receptor. It is also the part of the feedback system. It's function is to monitor the physiological value. This is the value which is reported to the control center.

Answer:
The correct answer to the questions: What is the name of the medical term for an abnormal condition of artery hardening, and why is it dangerous to have this disease? would be as follows:
1. The name of the disease in which the walls of the arteries become hardened and the lumen of the vessels through which the blood flows become constricted, is atherosclerosis, or also arteriosclerotic vascular disease. This disease speaks about the deposition of fatty and triglyceride globes on the walls of the arteries, causing an obstruction of the lumen, and therefore difficulting the passage of blood through them. Also, these deposits make the normal flexibility and resilience of the arteries much less, which is why it seems like the vessels were becoming hardened.
2. It is a very dangerous condition precisely because of what it implies. First, by reducing the blood flow through the arteries, the organs that depend on the proper arrival of oxygenated blood to them, and the removal of waste, for proper functioning, start to suffer the consequences. One such organs are the kidneys, whose cells begin to die, and the organ to be damaged, due to a lack of proper oxygenation, and because they have to work double to filter the blood that flows to them. The other reason is that the body responds to the lowering of blood flow by increasing arterial pressure on the walls. This further decreases flow due to obstruction, and also increases the suffering of the organs, like the kidneys. If atherosclerotic disease is not controlled, it can lead to permanent loss of organs, and even death.
Answer:
Option-D
Explanation:
The myocardial cells form the cardiac muscle present in the heart. The heart receives its signal from the autonomic nervous system but not all the cells receive the signals.
The SV and AV node present in the upper heart produces the potential for the contraction. The action potential gets transferred through the cell and finally reach the lower ventricle through Purkinje fibres.
This allows the contraction of both the ventricles simultaneously and sows that the heart cells contract simultaneously.
Thus, Option-D is the correct answer.
