Answer:
1-The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
2-The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.
3-The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.
4-The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.
5- i havent seen the video then how can i answer q5
Answer:
macrophages
Explanation:
Macrophages are the specialized cells that perform phagocytosis which refers to the intake of microbes, pathogens, toxins, etc. to remove them from the body. During any injury, capillaries become more permeable under the influence of histamine and other substances. This allows the tissue fluid to move towards the site of infection. Monocytes are the phagocytes that arrive at the site of injury or infections along with neutrophils. Monocytes are transformed into actively phagocytic macrophages. Macrophages ingest the debris and pathogens and kill them by the hydrolytic enzymes present inside them.
