Lungs

oxygen is required in a process known as aerobic respiration. This is where an organism breaks down sugar step by step using oxygen to release energy which is used elsewhere in the organism.

true

the left lung is divided into 2 parts in mammals

For the most part, no - fluid enters the lungs due to problems with the membranes and the cells of the lungs. Because this is a passive flow following the path of least resistence, there isn't much a doctor can do to stop it directly.

The left lung (which has two lobes) has to be smaller than the right lung (which has three lobes) because space on the left side is occupied by the heart and its associated blood vessels.

Air enters the lungs because the pressure in the atmosphere is greater than the pressure in the lungs.

Lung pressure is lowered by increasing the volume of the lungs. This is achieved by lowering the diaphragm and raising the rib cage.

It's An Orange Peel Except With Less White Stuff

no, i guess

the trachea

trachea

It basically is used to burn fuel to power the body, more or less just like a campfire uses the air to burn. When the blood goes to the lungs, oxygen is absorbed in and as it leaves the lungs to go to the different parts of the body, it provides the energy. Therefore, the lesser the amount of oxygen in the blood, the weaker we become and body organs will die ultimately.

In the lungs, cells called alveoli form a thin membrane between the lungs and the capillaries. The alveoli extract oxygen from the air inhaled by the diaphragm, and transfers the oxygen to hemoglobin in red blood cells, which transport the oxygen to other parts of the body.

Simple Squamous Epithelium
im not sure exactly what youre asking...the section of the bronchioles is called the ALVEOLI; the place where the diffusion of O2 and CO2 actually happens. alas, phrasing makes your question unclear as to what you mean to ask.

on the right

The mucociliary elevator is the means by which particles trapped in the mucus of the lungs (produced by goblet cells) is transported out of the lungs, up the trachea, and into the pharynx where it is then swallowed. Cilia on the cells lining the respiratory tract move back and forth to move the mucus.

alveolar = air sac simple squamous epithelium; single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm; the simplest of the epithelium. function: allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae. location: kidney glomeruli; air sacs of the lungs; lining of hear, blood vessels, and lymphatic vessels; lining of ventral cavity (serosae).

Singers inhale air into their diaphragm because it holds more air than your lungs.

No. Your lungs pass oxygen into the blood and also pass carbon dioxide to the air outside your body.

Oxygen combines with carbon to form carbon dioxide. This happens in our muscles, among other places.

There are millions of the tiny tubes in each of the kidney to carry blood and other nutrients both inside and outside of the kidney. The artery basically divides into many tiny blood vessels throughout the kidney.

the alvioli

The air pressure changes inside and outside the body, breathing takes place.In normal conditions,air moves from high pressure area to low pressure are.

Most models use 2-liter soda pop bottles to model the lungs, I prefer the smaller, cheaper plastic cups in a classroom setting. Each breath begins with a contraction of the diaphragm, a dome-shaped sheet of muscle that lies just below the lungs. When you inhale, your diaphragm contracts, or flattens downward. This contraction creates a lower pressure in your chest cavity. Normal outside air pressure forces air through the nose and mouth, down the trachea and into the lungs. When you exhale, your diaphragm relaxes, increasing pressure on the lungs and forcing air out of the body. Materials: Flexible straws Clear plastic cups (7, 8 or 9 oz) Small balloons Large balloons Scissors Modeling clay Scotch tape Rubber bands Steps 1. Make a hole about the diameter of a straw in the bottom of the plastic cup with the scissors 2. Cut a 5 cm inflexible section of a straw 3. Make a small slit in the elbow of another straw 4. Insert the 5 cm piece of straw into the slit to form a "Y". Use some modeling clay and tape to make the joint airtight. 5. Tape the small balloons to each end of the diagonal segments of the "Y". Make sure these connections are airtight. 6. Thread the vertical (long) leg of the "Y" through the hole in the cup and seal with clay. 7. Cut the neck off the large balloon. Cover the open end of the cup with the rest of the balloon, use rubber band and tape to secure it. In this model, the cup is the chest cavity, the straws are the bronchi and trachea, the small balloons are the lungs, and the big balloon is the diaphragm. Manipulating the large balloon (pulling it out and pushing it in) will cause the small balloons to inflate and deflate, modeling breathing.

you had a clotted nosebleed, injured An internal organ or vommited too much Depends on where the blood came from. If the blood comes from a nosebleed, it means you have a contusion in your nose, and you're bleeding down into your mouth. This could also indicate bleeding gums, or lacerations in the mouth or throat. You use the term spitting up. If you mean vomiiting blood, you're discussing a hemorrhage -- and this one requires a 911 call (possibilities include upper or lower gastric hemorrhage, esophageal varices, and other conditions). If you mean coughing up blood, this could indicate an insult to the lungs -- a visit to the hospital is called for now. If the bleeding is copious, call 911. A little more information would go a long way in helping me answer this.

With each breath, the lungs take in oxygen and remove carbon dioxide.

the lungs have a great surface area thanks to the alveoli; have an extremely thin (1 cell thick) epithelium.
