Question
Understand the equations describing the flow and resistance to the flow as the blood travels through the vasculature (parameters in the equations, and their importance in affecting the flow and resistance) Mechanisms used in the transport of gases (O2 and CO2) in the blood Chemical reactions involved in the transport of oxygen and carbon dioxide within blood Understand the oxygen-hemoglobin curve as it relates to the ability of hemoglobin to be saturated with oxygen at different partial pressures Importance of small changes vs large changes in partial pressure with respect to the effects of these changes in altering the saturation of hemoglobin with oxygen. How is this curve affected under various circumstances (i.e., pH change/Bohr effect, altitude change)? Why does it have "sigmoidal" versus a "straight line" shape? Main chemical groups of hormones, what is the difference between these groups, and how their functions differ. Differences in the way that the hypothalamus stimulates the anterior part vs the posterior part of the pituitary gland. Understand the hypothalamic-pituitary-adrenal axis, and how defects in Cortisol secretion may affect the metabolism of glucose, what are some other responses, outside glucose metabolism, affected/regulated by Cortisol? Path that electrons follow during the process of glycolysis Chemiosmotic theory Importance of the sodium potassium pumpExplanation / Answer
human hormones
four main chemical classes:
Plant hormones include abscisic acid, auxin, cytokinin, ethylene, and gibberellin.
Differences in the way hypothalamus stimulating anterior and posterior part of pituitory gland:-
The anterior lobe produces and releases hormones. The posterior lobe does not produce hormones per se—this is done by nerve cells in the hypothalamus—but it does release them into the circulation.
The anterior lobe releases hormones upon receiving releasing or inhibiting hormones from the hypothalamus. Anterior lobe harmones ;-Adrenocorticotropic hormone (ACTH),Follicle-stimulating hormone (FSH),Growth hormone (GH),Luteinizing hormone (LH),Thyroid-stimulating hormone (TSH).
The posterior lobe contains the ends of nerve cells coming from the hypothalamus. The hypothalamus sends hormones directly to the posterior lobe via these nerves, and then the pituitary gland releases them.
Posterior Lobe Hormones: Anti-diuretic hormone (ADH), and Oxytocin
