What is the natural pacemaker of the heart where the cardiac electrical
impulse begins?

Answers

Answer 1

Answer:

node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.

Answers

Answer:

Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems. Smooth muscle is also present in the eyes, where it functions to change the size of the iris and alter the shape of the lens; and in the skin where it causes hair to stand erect in response to cold temperature or fear.

Please select the best answer from the choices provided.


A
B
C
D

Answers

Answer:

High blood pressure has no symptoms, therefor the answer is D.

Explanation:

High blood pressure is identified by chest pain. High blood pressure, or hypertension, is a condition in which the force of your blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.

What happens in the case of high blood pressure ?

In most cases, high blood pressure does not cause symptoms. Arteriosclerosis is a condition where your arteries harden and narrow, and atherosclerosis is a condition where plaque builds up in your arteries. Both of these conditions can lead to high blood pressure.

Arteriosclerosis and atherosclerosis are conditions that involve the hardening and narrowing of arteries due to the buildup of plaque. While high blood pressure (also known as hypertension) can be a risk factor for these conditions, it is a separate condition that involves consistently elevated blood pressure levels.

Unlike arteriosclerosis and atherosclerosis, high blood pressure doesn't always have symptoms. It is often called the "silent killer" because it can lead to serious health problems such as heart disease and stroke without showing any noticeable symptoms. However, it can be treated with lifestyle changes and medication.

Therefore, option D is the correct answer that distinguishes high blood pressure from conditions such as arteriosclerosis and atherosclerosis.

D) Assault Victims' Bill of Rights Act

Answers

The Jeanne Clery Disclosure of Campus Security Policy and Crime Statistics Act mandates that colleges and universities receiving federal funds provide information concerning crime on and around their campus. Hence option A is correct.

In order to promote openness and safeguard the safety of faculty, staff, and students on campus, this law, also known as the Clery Act, was passed in 1990 and requires that institutions of higher education record and publish information concerning crime statistics, security policies, and procedures.

Among other things, the Clery Act mandates the release of an annual security report, prompt alerts about potential risks, and the upkeep of a public crime register.

Fitness is defined as the ability to carry out daily tasks with optimal performance, endurance, and strength while managing disease, fatigue, and stress and engaging in less sedentary behavior.

Fitness entails some type of activity that enhances various systems of the body and retains a certain state within the body.

Health, on the other hand, involves every system within the body and can only be achieved through a healthy lifestyle.

The sit and reach test is a common flexibility test that assesses the flexibility of the lower back and hamstring muscles.

This test is important because lumbar lordosis, forward pelvic tilt, and lower back pain are all associated with tightness in this area.

Thus, the correct option is B.
