CHEMICAL SIGNALS MAINTAIN HOMEOSTASIS Endocrine System: a system of glands that secrete hormones to regulate body function Hormones: chemical messengers or regulators • they are released by cells in one part of the body and affect cells in other parts of the body to speed up or slow down processes. Endocrine Hormones – are produced in glands and secreted directly into the blood and distributed by the circulatory system. Makes hormones and regulates the pituitary gland Pineal gland (makes serotonin

The Endocrine System Sarah Horton Texas Woman’s University Introduction The endocrine system is one of two systems in the human body that regulates all bodily functions. It is comprised of organs called endocrine glands and include the ovaries‚ testes‚ pituitary‚ hypothalamus‚ pineal‚ pancreas‚ kidneys‚ thyroid‚ parathyroid‚ thymus‚ and adrenal glands. These glands‚ which are spread throughout the body‚ are responsible for the extensive and enduring release of certain hormones into the bloodstream

the kidneys Sphincter is like a rubber band which keeps the opening of the bladder so that urine can pass down through the urethra urethra‚ tube that allows urine exits the body. 4. Discuss your dissection of the components of the endocrine system of the fetal pig by doing the following: a. Describe the endocrine organs that are located in the throat region (e.g.‚ function and appearance). Thyroid - small dark brown‚ pink gland in the trachea. Its function is to regulate metabolism and secrete

person would be quite tired/exhausted‚ but with the correct fitness exercises to work on cardiovascular endurance it would get easier and easier to run such an event. The reason your cardio performance can be improved is because the heart is a muscle‚ and like all other muscles in the body if you keep working it it will adapt to the workload given. This allows us to have direct control of how healthy one of the most important systems in our body is. Your body will also adapt to running the aquathon

Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

Predict Question: Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction velocity will be the same in both fibers. Stop & Think Questions: 3. Note the difference in time between

area of LOW to High solute concentration. 3. Because water moves toward the HIGH concentration of solutes. 4. We know the pressure will increase in the albumin beaker because it is more impermeable than glucose. The pressure in the beaker containing the albumin increased despite the increased concentration of glucose because albumin has a much greater molecular weight. Activity 4 1. Increasing the size of an opening allows more space for movement. For example‚ the more you open the nozzle

Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight
