The condition in which the heart does not circulate blood at a satisfactory rate is known as <u>heart failure.</u>
<u></u>
<h3>What is heart failure?</h3>
The name of this condition can be a little confusing. When you have heart failure, it doesn't mean your ticker stopped beating. What's really going on is that your heart can't pump blood as well as a healthy one.
The chambers of your heart may respond by stretching to carry more blood to pump through your body. They may become stiffer and thicker. This helps keep blood moving for a while, but in time, your heart muscle walls may get weaker.
<h3>What Causes It?</h3>
- Coronary artery disease is a problem with the arteries that supply blood and oxygen to your heart. It means less blood flows to your heart muscle. When the arteries narrow or get blocked, your heart becomes starved for oxygen and nutrients and can't pump as well.
- Heart attack may happen when a coronary artery is blocked suddenly, which stops the flow of blood to your heart muscle.
- Cardiomyopathy is damage to your heart muscle. It can be caused by artery or blood flow problems, infections, and alcohol and drug abuse. Other diseases or genetic issues can also bring it on. Make sure your doctor knows your family's health history.

Answer:
The correct answer will be- to provide smooth surface at the ends of synovial joint.
Explanation:
Articular cartilage is the white smooth tissue present at the end of the bones which covers the bones at the joints. The articular cartilage is devoid of the nerves, blood vessels and lymphatics but is exposed to the biochemical environment.
The cartilage at the joint helps in the movement of the bones by reducing the friction produced by gliding or sliding of the bones over each other.
Thus, to provide a smooth surface at the ends of synovial joint is the correct answer.

Answer:
E. We most often naturally awaken during NREM-3 sleep.
Explanation:
Sleep can be defined as a biological recurring state in which the mind and body of a living organism is characterized by altered (partial or total) consciousness, lessened sensory and muscular activities, as well as reduced physical interaction with the environment.
Generally, there are four (4) main pattern of sleep cycles and these includes;
I. Stage 1 sleep.
II. Stage 2 sleep.
III. Stage 3 sleep.
IV. Stage 4 sleep.
V. Rapid eye movement (REM) sleep.
Rapid eye movement (REM) sleep involves the movement of the eyes under the eye lids and this is the stage where dreaming occurs.
Hence, the statement about the typical pattern of sleep cycles which is false is that, we most often naturally awaken during NREM-3 sleep.
