The arteries carry nutrients and oxygenated blood to the body’s tissues. The veins return de-oxygenated blood to the heart, where the cycle repeats itself continuously. However the blood vessels have a closed type of cardiovascular system in which blood doesn’t come in direct contact with the body tissues. Instead the blood flows in restricted pathways called blood vessels. The blood vessels are pathways of blood flow in the body.
6. What is the relationship of the bronchi, the bronchioles, and the alveoli? The bronchi, bronchioles, and alveoli are all in the lungs and they are all used in the process of breathing. The bronchi is what the trachea branches off into. The bronchioles are the smaller branches that the bronchi divide into.
The cough reflex is a long and deep inhalation followed by the closing of the glottis, this causes a strong exhalation that pushes the glottis open and sends air through the respiratory passages. Coughing can occur when a foreign body is located in the larynx, trachea or epiglottis. Cari is coughing due to the mucus and fluid buildup in her lungs and her body is trying to expel it. Question C: Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? Alveolar macrophage protects her lungs by wondering around the alveoli space collecting dust, particles and debris.
mean: SYNCOPAL EPISODE- A temporary loss of conciousness due to cerebral ischemia; fainting. mean: TISSUE RESISTANCE TO VENTILATION- The work or pressure required to displace involved body tissues during ventilation mean: VALSALVA MANEUVER- A forceful expiratory maneuver againts a closed glottis. mean: Tests for pulmonary mechanics are used to assess function of the pulmonary/thoracic system under dynamic conditions.Dynamic testing may be used in conjunction with lung volume tests to confirm suspected pulmonary disorders. some disorders, such as upper airway obstruction, may exhibit themselves only through this type of study. pulmonary mechanics tests are used to evaluate a variety of breathing maneuvers and dynamic ventilatory parameters.
Water beneath the surface becomes insulated and less likely to freeze. | Lakes tend not to freeze completely so aquatic organisms aren’t killed as temperatures fall. | Thermal Stability | Large bodies of water have fairly constant temperatures.Evaporation of water can cool surfaces by removing heat. | Oceans provide a relatively stable environment in terms of temperature.Many land-based organisms use evaporation as a cooling mechanism, for example in panting or sweating. | Metabolic | Water takes part as a reactant in some chemical processes.
RNA will help repair the cells. E. Joseph’s heart attack has caused the function of his cells to change. What types of proteins in the cell membrane were involved in the homeostatic imbalances of his heart cells? ATP needs oxygen in the cells, for energy, without the heart pumping; the oxygen is limited and or cut off. Homeostasis can shut down causing imbalance of water, pH balance and ionic equilibrium, all factors of homeostasis in individual cells.
Stimulus for the reflex could be a foreign body in the larynx, trachea, or epiglottis. Cari’s body is causing the cough reflex due to mucus and fluid buildup in her lungs. C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? Alveolar macrophage protects the lungs by wondering around the alveoli spacing collecting dust particles and debris. Smoking has caused the cilia in the respiratory passages to become paralyzed and secrete excess amounts of mucus, macrophages are being sent to her lungs continuously and is getting stuck in the mucus instead of fighting off the pathogens.
The breakdown of the membranes of these structures, affect the function of his heart cells because lysosomal enzymes which are normally bound safely inside vesicles will digest the plasma membranes and the membranes of the organelles. D.) Predisposition means that Joseph inherited vascular disease. Dna is in the nucleus of the cell. We need DNA to replicate or repair our cells. Also, cytosol is the site of chemical reactions needed to maintain cell structures and allow cell growth.
Surfactant promotes easy expansion (inhale) of the alveoli and prevents the alveoli from collapsing during exhale. It also reduces the effort needed for the lungs to expand and contract during breathing. Gas exchange within the lungs and body tissues is vital for life to exist. Briefly explain the PROCESS OF gas exchange that occurs in the lung
