What is the medical term meaning disease characterized by loss of elasticity overexpansion and destruction of the alveoli?

emphysema
emphysema
Chronic obstructive pulmonary disease (COPD). This is most often caused by cigarette smoking.
Its called the Emphysema


Emphysema is one disease that can cause the pulmonary alvioli to be useless. Lung cancer is another one. COPD (Chronic Obstructive Pulmonary Disorder) is also responsible for making alvioli useless.

Emphysema is correct, but what actually happens is that the delicate one-cell-thick walls of the alveoli are damaged and replaced by thick scar tissue which cannot allow the diffusion of gases to and from the blood. This damage cannot be reversed.
It is called emphysema.
It is Emphysema and it can take 20 to 30 years to develop

Alveoli

How does the structure of the alveoli relate to its function in the lungs?

Alveoli are similar to cells in the sense that they have a large surface area to volume ratio. This is advantageous since they depend on there surface to allow as much oxygen as possible to diffuse through.

Therefore, the correct answer would be something like this :

Since alveoli's have a large surface area to volume ratio, it oxygen to diffuse through. More oxygen can be absorbed. If the alveoli had a smaller surface area to volume ratio, it would be very difficult for oxygen to diffuse through. Therefore, it is advantageous for the alveoli to be small in volume, but great in surface area.

What are the structures in the lungs where gas exchange takes place?

The alveolus (plural = alveoli) is the tiny air sac in the lung where gas exchange occurs. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues. Carbon dioxide produced by the body's metabolism returns to the lung via the blood. It then diffuses across the capillary and alveolar walls into the air to be removed from the body with expiration.

The alveoli have a structure specialized for efficient gaseous exchange:

  • Walls are extremely thin.
  • They have a large surface area in relation to volume.
  • They are fluid lined enabling gases to dissolve.
  • They are surrounded by numerous capillaries.

How does gas exchange occur in the alveoli?

Gas is exchanged by diffusion.

We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale?

The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth.

In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.

What is the process of gas exchange in the human body?

We breath in oxygen then it travels through the respiratory system ending to alveoli. Oxygen passes through the blood stream by using capillaries as a place to swap with carbon dioxide so that the alveoli gets the oxygen. Then the carbon dioxide leaves the body when we exhale.

What is the partial pressure of oxygen?

The partial pressure of oxygen will vary according to where you look. Atmospheric oxygen partial pressure is approximately 21% of the atmospheric pressure of the location at which you measure (typically around 1 atmosphere at sea level, making the partial pressure of oxygen at seal level 0.21 ATM or 21.3KPa). The value varies geographically and with time, but also varies in different tissues of organisms, since not all oxygen available is absorbed, and complex multicellular organisms will have certain tissues (respiring muscle) that use up oxygen, resulting in a lower partial pressure there.

normal oxygen partial185.4 kPa

or in another unit:

100 mmHg in the arterial blood. The partial pressure on the alveolar site is about 105 mmHg.

How do alveoli speed up gas exchange in normal lungs?

They increase the surface area and hence the rate of reaction is increased...

So gas exchange can be much quicker, especially as the bloodstream flows very close to them

Exercise

What are the effects of exercise on the musculoskeletal system?

That depends on the exerise or sport. For example, if you run a lot you may get bad knees from the pressure of you running. Running is a high impact exercise. If you swim it doesn't affect your skeletal system as much. You may be sore in the morning if you swim a long way but that will be your muscles growing. Swimming is a low impact sport and so is cycling.

Tennis is bad for both the skeletal and the muscular system because if you play tennis regularly you may get tennis elbow and you get bad knees from running quickly then stopping suddenly. This is why most tennis players have bad joints when they are older.

Running and tennis are the sports most likely to give you arthritis in your ankles, knees and possibly your shoulders. So, a low impact sport is good. Swimming 100m is the equivalent of running 400m. So, if you want to have good joints swimming is the way to go.

What happens to a person who is born with one lung?

A small percentage of babies are born with one lung. This can result from birth defects such as congenital diaphragmatic hernia, where the diaphragm is incompletely formed.

The condition is not uniformly fatal, except where the lung is not the only organ with a serious defect (heart, liver, kidneys). Many children who survive infancy with one lung can lead normal, active lives. There are usually medical problems that can be worsened, however, in the absence of two complete functioning lungs.

Conjoined twins are often separated, and in some cases may have only one lung each after surgery.

Can you simply drain a clothes washer through an outside wall and onto the ground?

My grandmother's house used to have drainage for her washer that was piped out of the house and onto the ground. She lived on a farm with a well, so there were no city ordinanced regarding water. Problems with this that I can think of as a non-professional: 1) The water might run close to the house and cause water to pool close to the foundation causing flooding issues. 2) Substances on clothes (any oils, chemicals, etc.) could go directly into ground water and grass unfiltered. I'd call a pro and ask about this one.

What Is the Affect of Emphysema on Expiratory Reserve Volume?

Expiratory reserve volume is decreased in a patient with emphysema. This patient will struggle to breathe out because air is getting trapped within the lungs. There is also an increase of co2 in the blood because of the inability for the patient to exhale.
