Illness Associated with Lungs!

Asthma- briconchales constricts (becomes smaller) reducing size of avrivays. Emphysema is when the lungs become stiff with fibers and less elastic muscles must work hard. Bronchitis is when airways become inflamed and narrows. Pneamothoray is air in the chest cavity that equalizes pressure inside and out causing lungs to collapse. Apnea is breathing slowly or not at all. Pulmonary edema is fluid between alveolars and capillary builds up. Increases distance over which causes exchange. Smoke inhalation is smoke particles coat the alveolars and prevent gas exchange. Carbon monoxide poison is when carbon binds to hemoglobin more tightly than either oxygen or CD.(CO2)

Heart

1, The difference between the left ventricle and the right is that the right ventricle is the chamber that receives the blood from the right atrium. It then pumps the blood into the lungs. The left ventricle is thicker because, it is the chamber that receives blood from the left atrium and pumps it into the system circulation, throughout the body.
2, The aorta looked like a tube that felt extremely tough and stretchy, it is this way cause its delivers the blood from the heart to the rest of the body.
3, The aorta didn't have much of its own blood supply.
4, Their where two pulmonary veins that lead into the right atrium, and two that lead to the left atrium..
5, The heart muscle, known as the myocardium is the muscular tissue of the heart. It is composed of specialized cardiac muscle cells. The cardiac muscle can contract electricity but also conduct it, like nerves.

Digestive System

1, Carbohydrates are simple molecules. They are straight chains Keaton's with many hydride groups added. Usually one of each carbon atom isn't" t part of the rettox function group. Carbohydrates are one of the most abundant molecules that fill important roles. Most important roles are storage, transporting energy, and structural components. Carbohydrates are broken down in the small intestine.

2, Animals store glucose as cells convect to starch. This happens in the liver and muscle tissues as an instant source of energy.

4, Saturated fat is a type of single bound animals and vegetable fat as that found in butters, meat, egg yolk, coconut, or palm oil. Saturated fats can also increase cholesterol levels in the blood of humans.
Unsaturated fat is liquid (in room temperature) fat from derived plants and some animal sources, such as fish. It can reduce blood cholesterol levels, if there is less saturated fat intake.

5, Osteoporosis is a disease when lacking calcium, such as milk.

6, Bile is a fluid that is secreted by the liver and stored in the gallbladder. It aids in absorption and digestion of fats.

7, Rickets is caused by lack of vitamin D.

8, Large intestines main function is to absorb water fran and eliminates the residue of digestion.
