The indigestible portion of plants that helps move food along digestive system is known as roughage or bulk
Roughages are polysaccharides that the digestive enzymes are unable to hydrolyze. Dietary roughage should be a major component. Water can be absorbed by fiber and held in the body. Dietary fibers make defecating more comfortable and soften the feces, which helps to prevent constipation.
Roughage is a component of almost all plant meals. The best sources include chia and flax seeds, pears, beans, lentils, wheat bran, and lentils. Bloating, gas, and constipation can be brought on by eating too much fiber. By drinking more fluids, doing more exercise, and changing their diet, one can get rid of this discomfort.

#SPJ4
<span>1. The average heart beats about 100,000 times a day.
True
Normal heart rate is about 60-100 beat/minute. If you calculate it, the range should be: 60*60*24 - 100*60*24= 86,400- 144,000 beats/day. Then it should be true that average heart will beat around 100,000beats/day
2. The heart is located inside the ribcage and just to the right of the breast bone.
False
Heart is located inside the ribcage. The location is in the middle of the ribcage, but more part is located on the left side. This is one of the reason why left lung has lower lobe count than right lung.
3. The heart has four chambers and is divided into a right and left side by a muscular wall called the septum.
True
The heart is divided into four chambers. The upper chamber called atrium, the lower chamber called ventricle. The chamber is divided by a muscular wall called septum. Without the septum, the rich oxygen blood can be mixed with poorly oxygenated blood
4. The two atria hold the blood that circulates away from the heart.
False
The atria hold the blood that circulates TO THE HEART. Atria will send the blood to the ventricle and the ventricle sends the blood to circulate away from the heart. The muscle on ventricle is much bigger than atria since ventricle need bigger force than atria.
5. The heart has four one-way valves, which open and close with each heartbeat.
True
There are one valve for each chamber of the heart. This valve is important to make sure the blood move in one way. This valve increases the effectivity of the heart pump. Damage to the valve will lower the heart effectivity and increasing its load.
6. The tricuspid valve and the mitral valve are located between the atria and allow the blood to flow from the atria to the ventricles.
True
Tricuspid valve and mitral valve sometimes called atrio-ventricular valve because it was located between atrium and ventricle. Other valve called aortic valve for the valve in left ventricle and pulmonary valve for right ventricle.
7. Arteries carry oxygen-poorblood from the heart to the body’s tissues and organs.
False
Arteries carry oxygen-RICHblood from the heart to the body tissue. Pulmonary arteries carry oxygen-poorblood but it will send the blood to the lung, not the body tissue. The blood sent to the body tissue should have high oxygen level as the body tissue need oxygen to make energy.
8. Since the arteries keep pace with the heart, you can measure the heart rate by counting the contractions of the arteries.
True
The pulse of arteries is matching the pulse of the heart. In the medical field, the heartbeat is count by palpating the brachial or radial arteries in your hand. But palpating the heart can give other information besides the beat so it still was done.
9. Capillaries are the largest of all blood vessels.
False
Capillaries are the smallest blood vessels. The bigger blood vessel should be aorta which was the blood vessel right after the heart. Since it has to withstand the heart pumping pressure it has a big thick wall.
10. The exchange of oxygen and carbon dioxide takes place through the capillary wall.
True
Exchange of oxygen and carbon dioxide need to happen in the capillary wall. Capillary wall only has a thin wall so it will be easier to diffuse the gas. The surface area of the capillary wall is also much bigger than another vessel so the diffusion rate will be higher.</span>
