Explanation / Answer
1.98.5 Oxygen is transported by RBC as oxyhaemoglobin.
2.bicarbonate form.
3.Oxygen and carbon dioxide are major factors in breath control or regulation of respiration.
Respiration is controlled by these areas of the brain that stimulate the contraction of the diaphragm and the intercostal muscles.
4.increases in PCO2 and H+ concentration in capillary blood
-declining pH=more acidic these factors work to ensure oxygen unloading in the vicinity of working tissue cells .
5.alveolar epithelium,capillary epithelium,.basement membrane separating the two.
6.There are three main factors that can influence the pulmonary ventilation.
Airway Resistance or friction (drag) encountered in the respiratory passageways.,
Alveolar Surface Tension,
Lung Compliance.
7.the pressure within the lungs is intrapulmonary pressure is greater than that outside the lungs (intrapleural pressure), the difference is called transpulmonary pressure.
8.bile juice , help in DIGESTION of lipids.
9.primary pancreatic juice contain alkaline bicarbonate.
10.primary pancreatic juice help in neutralization of acidic chyme.
11.gastrin act on stomach and increase gastric juice production.
12. Excessive vomiting causes dehydration and electrolyte imbalances in blood.
13.except larger proteins remaining composition is equal to plasma.
14.counter current flow mechanism.
15.reabsorption of water at DCT and collecting duct by ADH action.
