Be sure to grab a sheet from the front of the room. Bellwork: Be sure to grab a sheet from the front of the room. Set up journal for cornell notes Page:_____ Title: Body systems-Regulation EQ: What systems work together to regulate all body systems and how do they interact? Notecards are due Tomorrow, March 7th (word, definition, picture in color) Pre-AP: Have homework out and ready to be checked

Did we finish feedback loops?

If you turned in a BTP application you MUST attend the Monday or Wednesday meeting after school if you want to participate. We will meet in Mr. Garza’s room. Portable 101A

Time for some interaction! Who’s got some $$$ ?

Catch the Dollar 

Today you will be working independently (TEST CHAMPS) You will have a checklist of items to complete. These items will all count for a grade. You will have the entire class period to complete a minimum number of required items. Extra credit is available to those willing to work for it. Let’s go over your options and requirements for today…

Title: Body systems-Regulation Cornell Notes: Page:_____ Title: Body systems-Regulation EQ: What systems work together to regulate all body systems and how do they interact? *Be sure to view this power point in full screen mode

Standard: describe the interactions that occur among [animal] systems that perform the functions of…regulation… (B.10A)

This unit will focus on how body systems interact to perform four main functions: Regulation Nutrient Absorption Defense against injury and illness Reproduction *As you move through the lessons in the unit, keep these four functions in mind. Everything we discuss will always come back to these four processes.

What body systems are involved in controlling the entire body? This presentation will focus on the body systems involved in the REGULATION of all bodily processes. What body systems are involved in controlling the entire body? *great left handed question 

Copy this diagram into your notes! The regulation of all body processes is controlled by the Nervous and Endocrine systems. REGULATION (control) Nervous Endocrine Copy this diagram into your notes!

NERVOUS SYSTEM Main Parts/Key words: Brain Spinal cord Neurons (nerve cells) Sensory organs Eyes Ears Tongue Nose Skin

The NERVOUS SYSTEM How It Works: Neurons (nerve cells) are “wired” into a complex network that run from the brain to the rest of the body Connections allow electrical signals to be transmitted between nearby cells Reflexes: Quick and immediate feedback/responses

TYPICAL MOTOR NEURON dendrite muscle tissue Axon cell body synapse Impulse in a Neuron muscle tissue TYPICAL MOTOR NEURON Axon dendrite synapse cell body cell body

What diseases affect the nervous system? Examples include: Parkinson's disease. Multiple sclerosis (MS). Amyotrophic lateral sclerosis (ALS). Alzheimer's disease. Huntington's disease. Peripheral neuropathies. This list is important for some of your menu options. You may want to take a picture of this 

ENDOCRINE SYSTEM Main Parts/ key words: Glands Hormones Do not skip to the next slide without reading about what these glands to for the body

ENDOCRINE SYSTEM How It Works: Each gland releases a specific hormone Hormones transported through the circulatory system used as chemical communication signals Slow-acting, gradual, long-term responses Exceptions include: adrenaline (fight or flight) Puberty, aging, growth spurts

DEBRIEF: Why we need the nervous and endocrine systems. The nervous and endocrine systems control all the body’s responses, so no other organ system would be able to function without these two regulatory systems.

Hormones are Extremely Powerful

Some hormone functions and disorders

Pituitary Gland Function: It secretes nine hormones that directly regulate many body functions and controls functions of other glands. Disorders: To much growth hormones (GH) in early childhood can result in a condition called gigantism. To little GH can result in Pituitary Dwarfism. Robert Wadlow

Thyroid Gland Function: plays a major role in regulation the body’s metabolism. Disorders: If the Thyroid Gland produces to much Thyroxin, it can cause a condition known as Hyperthyroidism. If to little thyroxin produces it is called Hypothyroidism.

Pancreas Function: The Insulin and Glycogen in the Pancreas help to keep the level of glucose in the blood stable. Disorders: When the Pancreas fails to produce or properly use Insulin, it can cause a condition known as Diabetes Mellitus.

Adrenal Gland Functions: -The adrenal glands release Adrenaline in the body that helps prepare for and deal with stress. -Also regulates kidney function.

Ovaries Functions: Pair of reproductive organs found in women that produce eggs. Also secrete estrogen and progesterone, which control ovulation and menstruation.

Testes Functions: Pair of reproductive glands that produces sperm. Also secrete Testosterone to give the body its masculine characteristics.

Interaction of Glands The hypothalamus is located in the brain and controls the release of hormones from the pituitary gland. It is an important link between the endocrine and nervous systems.
