Where are cells found in the body? Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up theorgansin your body, such as your heart, liver, or lungs. Each organ has its own job to do, but...
Explain the types of bone cells. Describe the gross structure of the lungs and the pleurae. What are the types of tissues that make the skin a protective barrier? Describe the cells of osseous tissue. How does oxygen keep cells and tissues alive?

In the new study, Snoeck's team discovered new chemicals that complete the conversion of stem cells into the epithelial cells that coat the surface of the lungs. In fact, the researchers found evidence suggesting the cells could develop into six types of lung and airway epithelial cells, accord...

Endothelial cells form the inner lining of thecardiovascular systemandlymphatic systemstructures. They make up the inner layer of blood vessels,lymphatic vessels, and organs including the brain,lungs, skin, and heart. Endothelial cells are responsible for angiogenesis or the creation of new blood vess...
These make blood a red colour. One drop of blood contains about five million red cells. Red cells contain a chemical called haemoglobin. This binds to oxygen, and takes oxygen from the lungs to all parts of the body. form .med66. 红细胞(红血球)。红细胞使血变红。一滴血约含500万红细胞...
The lower respiratory tract is covered with a 75 m2 monolayer of epithelial cells that separate the outside world from the underlying vasculature and protect the interstitial tissue. Although the lungs are constantly exposed to pollutants and airborne microbes, pathogens seldom manage to cause disease...
After taking the quiz, you'll learn about all of your blood-pumping, food-digesting, and keys-remembering systems and organs, including the heart, brain, lungs, immune system, bones, and sensory organs. Each chapter also contains common myths of the particular body part that the authors will...
