Hi i need help with these Q corecting my mestake and please with explantion.
Thank you
The "Trigone" is a special area of the bladder marked by the entrances of the ureters and the urethral exit. This specific region is innervated by the ANS in the exact same way as the rest of the bladder. If oxygen is not present to collect the electrons from Complex IV of the ETS, the whole system will effectively shut down and ATP production will be significantly reduced. Most oxygen (98.5%) molecules are transported in the blood bound to the globin portions of hemoglobin molecules. The diaphragm and the external intercostal muscles are the primary muscles of quiet expiration. Surfactant is produced by Type II Alveolar cells found in the lungs and prevents the collapse of each alveolus by decreasing the surface tension in alveolar fluid. The lumen of the gastrointestinal tube is always considered to be an "external environment" that is outside of the body, so anything claimed from luminal contents must be transported across the GI tube wall. Digestion, for us in this class, specifically means the enzymatic breakdown of macromolecules. The "normal flora" of the large intestine utilize your indigestible food stuff as their primary nutrient source, produce vitamin K that is absorbed through by the colon mucosa, and normally produce about 2.5 L to 3.0 L of flatus (often containing noxious and toxic gases) daily that is passed out through the anal sphincters. Chief cells found in gastric pits/glands produce and secrete the inactive enzyme pepsinogen. Complex II in the ETS is the only one that does not "pump" a proton into the intermembrane space. Oxidative phosphorylation yields roughly the same energy (ATP) as do anaerobic metabolic pathways. If oxygen is not present, pyruvate can be enzymatically converted into lactate or ethyl alcohol. The enzyme phosphofructokinase is responsible for changing 2-PG into PEP. The "default" condition of urine production is to create small amounts of extremely concentrated urine. Adipose tissue is the most hydrated of all of the tissues in the human body (approximately 75% H_2O). The largest and most important source of H^+ that alter body pH is ingestion of acidic food & liquids. Juxtamedullary nephrons have really long nephric loops that descend deep into the medullary salt gradient &, although they are the minority, play the primary role in regulating final urine volume. ANP is secreted-from the atria & causes DCT & CD to excrete Na^+ ions & therefore H_2O. Perris can only proceed in the oral-to-anal direction in every part of the gastrointestinal tube. The distal portions (antrum/pylorus) of the stomach is the site where almost all of your protein digestion and absorption occurs. The esophagus is unique from the rest of the GI tube in that it has skeletal muscle in its wall for the initial portions of its length (neck/throat region). Oxygenated hemoglobin releases oxygen much more readily and quickly when the pH is basic. Your "need to breathe" or ventilation drive is to get CO_2 out more than it is to get O_2 into your system. Your TV or Tidal Volume is that amount of air that you ventilate during "heavy" or labored breathing. Multiple Choice Section Far each of the Moving questions, correctly select and mark the answer form the list of choices provided. Then is only one correct answer for each question. The ONLY site of gas exchange with "outside" air is in the ______. a. alveoli b. terminal bronchioles c. trachea d. bronchi e.Explanation / Answer
46.True-Trigone is a triangular region or tissue, particularly the area at the base of the urinary bladder, between the openings of the ureters and urethra.
47.True- Because oxygen is a final electron acceptor and if it is not present the whole system will shut down.
48.False- Most of the oxygen atoms are carried in the blood bound to heme portion of the hemoglobin.
49.True- The muscles that contribute to quiet breathing are the external intercostal muscles and the diaphragm. The external and internal intercostals are the muscles that fill the gaps between the ribs.
50.True- Pulmonary surfactant is a mixture of lipids and proteins which is secreted into the alveolar space by epithelial type II cells. The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung.r
51.True- because there is a continuous lumen starting and ending with openings to the outside of the body.
52.True- In chemical digestion, enzymes break down food into the small molecules the body can use.
53.True-Vitamin K is produced by the intestinal flora residing in our body and produce flatulence.
54.True- The gastric chief cell is a cell in the stomach that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.
55.True- Succinate-Q reductase (Complex II), in contrast with the other complexes, does not pump protons.
56.False- Oxidative phosphorylation produces far greater amounts of energy than in aerobic respiration.
57.True- In anaerobic respiration in the absence of oxygen pyruvate can be converted to ethyl alcohol or lactate.
58.False- Phosphofructokinase-1 is a glycolytic enzyme that catalyzes the transfer of a phosphoryl group from ATP to fructose-6-phosphate to yield ADP and fructose-1,6-bisphosphate .
59.False- Urine production depends on the intake of amount of water.If less water is in the body then concentrated urine is produced and if water present is more then the dilute urine is produced.
60.False- Adipose tissue is not hydrated as it contains stored fat which are water insoluble.
61.False- Main sources of hydrogen ions in the body are- aerobic respiration of glucose, anaerobic respiration of glucose, oxidation of sulfur-containing amino acids, incomplete oxidation of fatty acids, and breakdown of phosphoproteins and nucleic acids.
62.True- Juxtamedullary nephron is located near the vascular pole of the glomerulus and its main functionis to regulate blood pressure and the filtration rate of the glomerulus.
63.True- Atrial natriuretic peptide is secreted by atria. It Decreases sodium reabsorption in the distal convoluted tubule and cortical collecting duct of the nephron.
64.True- Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction.
65.False- Protein digestion and absorption is usually carried in the small intestine.
66.False- The upper third of the esophagus contains striated muscle, the lower third contains smooth muscle, and the middle third contains a mixture of both.
67.False- When the pH is acidic oxygen is released readily from the oxygenated hemoglobin.
68.True.
69.False. Tidal volume is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied.
