What are the two components of a nephron? - 1. Renal corpuscle 2. Renal tubule What is the function of the renal corpuscle? - Renal corpuscle filters blood plasma What is the function of the renal tubule? - Renal tubule refines the filtered fluid (filtrate) into urine Identify the components of a nephron and their functions. - Renal corpuscle: filters blood plasma Renal tubule: refines the filtered fluid (filtrate) into urine Identify the components of the renal tubule. - Proximal convoluted tubule (PCT), Nephron loop (loop of Henle), Distal convoluted tubule (DCT) Identify the cells that produce insulin. - Beta cells or B cells of the pancreatic islets Identify the cells that produce calcitonin. - parafollicular cells of the thyroid gland Identify the stimulus for release of insulin. - high blood glucose levels (hyperglycemia) Identify the cells that produce glucagon. - alpha cells (A cells) of the pancreatic islets Identify the stimulus for release of glucagon. - Low blood glucose levels (hypoglycemia) Identify the enzyme that is involved in the pathways of external and internal respiration and the reaction that it catalyzes - carbonic anhydrase and it catalyzes the conversion of carbon dioxide into carbonic acidIdentify the methods of carbon dioxide transport within blood - 1. Dissolved carbon dioxide 2. carbamino compounds 3. bicarbonate ions Identify the methods of oxygen transport within blood. - 1. dissolved oxygen 2. oxyhemoglobin Define hypoxia - a deficiency of oxygen at the tissue level Define hypocapnia - deficiency of carbon dioxide in the blood Define hypercapnia - elevated levels of carbon dioxide in the blood Identify a potential causes of an elevated basophil count. - Basophils elevate during allergic reactions Identify the structure that fails to function properly when a person chokes. - epiglottis Identify the structure that fails to function properly durin
