watch t.v. or-gain knowledge about organ systems

Now I know where the Georgia/Alabama line is. The line separating your organ systems from each other is not so black and white. It can get real fuzzy. The reason I bring this is up, is it not your bladder and kidneys putting themselves in the urinary system and keeping the stomach in the digestive system, it is us doing it. Why is that important? Because depending on who you are listening to, the answer can change. Some folks like to put “making red blood cells” in the skeletal system and some just leave it out. The list below, is what I like to use.

Also, please keep in mind that this is an introduction to the organ systems. As we go along, we are going to go into depth what each term means (and trust me mineral storage may not sound super cool but when we get to it, it is awesome)

In Latin Integument means cover. The Integument system is made up of:

skin, nails, hair, sweat and oil glands.

This lovely covering, does not only look good but it is responsible for:

Synthesizes vitamin D

Eliminates some wastes

Protects the body

Controls the temperature of the body

Detects sensation (ex. pain, cold, heat)

Skeletal system is made up of:

bone, joints, cartilage, and ligaments (ligaments connect bone to bone)

The skeletal system is responsible for:

protecting many of your most vital organs (think of the ribs as armour for you heart)

It provides mineral storage

It is the factory for blood cells

It is the framework that allow muscles to work

Muscular system is made up of:

Muscles and tendons (connects muscle to bone)

The muscular system is responsible for:

Maintaining your posture

Allows movement of the body

Produces heat

Nervous system is made up of:

the brain, spinal cord and of course your nerves

The nervous system is responsible for:

Respond and react to stimuli in the blink of an eye (think about how quickly your hand moves away from something that is hot)

Detects internal and external environmental changes and helps respond so that homeostasis is maintained. Does this by getting muscles and glands to respond.

Endocrine system is made up of:

Hormone producing glands: pineal, hypothalamus, pituitary gland, thymus, thyroid gland, parathyroid gland, adrenal gland, pancreas, ovaries and testes

The Endocrine system is responsible for:

Slower response then your nervous system

Regulates homeostasis/growth/body activities via the release of hormones

The Cardiovascular system is made up of:

the heart, arteries and veins.

Your Cardiovascular system is responsible for:

Getting your heart pumping. The heart is pumping blood, which is not only sending out oxygen, but hormones and the immune systems warriors to your entire body. You can say your Cardiovascular system is the subway system for your body.

Lymph system is made up of the spleen, red bone marrow, thymus, lymph nodes and lymphatic vessels

Lymph system Functions

Works hand in hand with the immune system by housing and feeding immune cells with information about what is going on in the body (one of the places that this occurs in are the lymph nodes)

Absorbs fluid leaked by the blood vessels and deposits it back into the blood.

Respiratory System is made up of the lungs, trachea, bronchi, pharynx and nasal cavity

The Respiratory System is responsible for bringing oxygen in and carbon dioxide out. Also, works with the acid-base balance of the bodily fluids

This Digestive System is made up of the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, anus, and liver

The Digestive System is responsible for breaking down food into what is needed by your body and what is not. It absorbs all the nutrients and eliminates waste.

This Urinary Systemis made up of kidneys, ureters, urinary bladder, and urethra

The Urinary System is responsible for regulating water (this helps regulate blood pressure), ph balance and electrolyte balance.

The Male Reproductive system is made up of prostate gland, penis, testes, scrotum, and ductus deferens

The Male Reproductive System is responsible for reproduction, which entails everything from making the sperm to delivery of the sperm. The testes also play a role in producing testosterone

This Female Reproductiveis made up of mammary glands, ovaries, uterine tubes, uterus, and vagina

The Female Reproductive System is responsible for reproduction, the mammary glands also do a bang up of job of producing milk. The Reproductive system also produces hormones for the lady, such as estrogen.

Embryology as told by Peter J. Ward

Short definition of embryology – the first 8 weeks of development after fertilization. The way cooler definition can be found at the below you tube by Peter Ward. I wish I was this cool. I also enjoy that he uses a really big knife to cut into play-doh.

Anatomy vs Physiology

The short answer to what is the difference between anatomy and physiology is (drumroll please) Anatomy = Structure and Physiology = Function. But what fun is the short answer?

Anatomy is derived from the greek work “cut up” (heebie jeebies anyone) and is the study of how your body is laid out. What makes it up, where is the stomach located and what shape is the stomach, how thick are the walls of your stomach, is it dark inside there? Anatomy tries to answer all those questions by mapping everything out. The fun does not stop there, anatomy will use everything it can get it’s hands, on to figure out how your body is built. X-ray, anatomy loves it, microscope, anatomy is on it, CT scans, anatomy is waiting on you to catch up. When you pop those poor squished cells of the stomach under the microscope you are hanging out in the anatomy zone. Looking at and mapping out the shape of all you see (and in the case of atoms, what you don’t see). For some good old anatomy fun http://www.innerbody.com/.

Physiology is all about how your body works. What is going on in that body? How does food go in one end and something entirely different come out the other? Physiology is asking those questions on all kind of levels. Physiology does not just want to know how does the stomach work, it goes further and asks how do the cells that make the stomach, work? Does physiology stop there, oh no, it goes poking around at the atoms, that make up the cell, how do they work? Physiology and Anatomy are relentless, they want to know it all and they want it written down in a book, reviewed by lots of other folks asking the same questions and then for good measure memorized. They’ll wear you out with their questions, questions, questions.

Anatomy and Physiology like to work together. Don’t know how something is functioning, good old anatomy will shoot it’s hand up and tell you how it is shaped, where all the cells are located, how many arteries it has going to it, on and on and on. Anatomy is not trying to muddy up the waters, it’s trying to help out Physiology. It’s saying to Physiology, listen here, I got this cell that has a bunch of mitochondria, not just some, but a bunch. Physiology gets to thinking, well mitochondria gives the cell energy, so if a cell has a lot of mitochondria, it must need a lot of energy, and if it needs a lot of energy it must be working. What that cell working at? Physiology does not know, but it knows it is not napping, which is more than it knew before Anatomy spoke up.
