The Human Body:An Orientation : 

The Human Body:An Orientation PART 1

An Overview of Anatomy :

An Overview of Anatomy : 

Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings An Overview of Anatomy Anatomical terminology Based on ancient Greek or Latin Provides standard nomenclature worldwide

The Hierarchy of Structural Organization :

The Hierarchy of Structural Organization : 

Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings The Hierarchy of Structural Organization Chemical level – atoms form molecules Cellular level – cells and their functional subunits Tissue level – a group of cells performing a common function Organ level – a discrete structure made up of more than one tissue Organ system – organs working together for a common purpose Organismal level – the result of all simpler levels working in unison

Systemic v. Regional Anatomy :

Homeostasis : 

Homeostasis Copyright © 2010 Marisa Bush…I added this myself All the systems of the body working together in one unit to maintain the body’s health

Which system is this? : 

Which system is this? I provide structural support, movement, and protection to vital organs. In addition, I make marrow and red blood cells.

Name structures in the musculoskeletal system. : 

Name structures in the musculoskeletal system.

Name structures in the musculoskeletal system. : 

Name structures in the musculoskeletal system. Bones Muscles Ligaments Tendons

Which systems do this? : 

Which systems do this? We protect the body from infection. We are made up of channels that transport fluid, but we are not the circulatory system. Our nodes enlarge when the body is threatened by infection or disease. We also include other structures that fight infections.

Name structures in the lymphatic and immune systems. : 

Name structures in the lymphatic and immune systems. The thymus, tonsils, bone marrow, spleen, lymph nodes, lymph vessels, tonsils and other lymphoid tissue are included in the immune system.

Which system does this? : 

Which system does this? My major organ is the body’s fluid pump. When that pump stops working, the rest of body cannot function and dies very quickly. I have an electrical system that controls this pump’s activity. I send deoxygenated blood to the lungs and oxygenated blood to the body. I have vessels that carry blood to the tissues, tiny vessels where oxygenated blood is exchanged with deoxygenated blood, and vessels that carry blood back to the pump.

Name structures in the cardiovascular system. : 

Name structures in the cardiovascular system. heart veins arteries capillaries

Which system does this? : 

Which system does this? I am one of the lightest systems, but I’m very important. If I am not working properly, the body will not get enough oxygen and won’t survive for long. I consist of two fairly large sacs that work like balloons, taking in and forcing out air anywhere from 17,000 to 30,000 times every single day. Inside, I have tiny sacs where oxygen is added to the blood, and tiny little hairs too! I am frequently abused, however. Many people inhale smoke from various plants, which can damage those tiny sacs and hairs.

Name structures in the respiratory system. : 

Name structures in the respiratory system. Upper respiratory – nose to throat Lower respiratory – trachea to lungs

Which system does this? : 

Which system does this? You would never believe this, but my biggest organ actually burns about 20% of the calories required by the body each day. Electrical signals fire inside me constantly, even when you’re asleep. I am very complex and though scientists have learned a lot about me over the years, there is still much about me people haven’t yet figured out. Ha ha ha! Good luck with that! I control all movement, all body functions, and EVERYTHING. I even control the weather…no, but I wish I did.

Name structures in the nervous system. : 

Name structures in the nervous system. In addition to the brain, the spinal cord and peripheral nerves are included in this system.

Which system does this? : 

Which system does this? I’m not as much of a control freak, and I don’t toot my own horn as much as the brain, but in my own way, I control almost as much as the nervous system does. I make hormones that help to control heart rate, blood sugar concentration, reproductive functions, and many other functions.

Name structures in the endocrine system. : 

Name structures in the endocrine system. Glands, including the pancreas, pituitary, adrenal, and the thyroid, which secrete hormones that affect multiple body functions

What system is this? : 

What system is this? I weigh about eight pounds but believe it or not, that makes me one of the body’s largest structures. I am not very thick. I cover a lot of square inches, though. (I also cover round inches…hee hee hee). I provide protection to all the structures of the body by keeping out infections and other invaders, maintain the body’s temperature, and by golly, most of the time I look really good doing it. People like to pierce me and write on me, but I still work just fine. I don’t handle overstretching, injury, and other abuse very well; I scar easily.

Name the main structure in the integumentary system. : 

Name the main structure in the integumentary system. skin

Which system am I? : 

Which system am I? I am kind of like the body’s wastewater management plant. I have two bean-shaped organs that work together to filter wastes out of the blood. You can live without one of them, but if neither one of them is working, you can only live if you’re hooked up to a blood-cleansing machine for many hours each week. My structures also include tubes that transport waste fluids, and a big reservoir to keep the waste in until you can take me to get rid of it. If I get a blockage, you will want to go to the hospital, because you will be hurting!!!

Name structures in the urinary system. : 

Name structures in the urinary system. The bladder, the ureters, and the urethra are also part of the urinary system.

Which system am I? : 

Which system am I? I am busy. I work really hard. I don’t think most people appreciate how special I am. I get blamed for a lot of things! I process the food you eat and break it down so you can absorb the nutrients. The biggest part of me is about 30 feet long and curled up into a compact little space. Inside of that structure, I have even more little folds so that your food is absorbed rapidly. I store the waste products left after the food is absorbed until you can take me to the restroom to get rid of them. Yet, people use the names of parts of me as an insult!

Name structures in the digestive system. : 

Name structures in the digestive system. The intestines are included as well as the mouth and oral cavity, the esophagus, and the anus and rectum.

Which system am I? : 

Which system am I? People use the names of my parts as insults too, but they love me. They really do. After all, if it weren’t for me, they wouldn’t be here, because everybody has their beginnings in my system. Besides that, most of them enjoy what I do for them. I manufacture baby humans. In men, I produce the cells that fertilize the cells produced by women. In women, I provide a nice incubator for baby humans to develop until they’re ready to live in the world.

Name structures in the reproductive system. : 

Name structures in the reproductive system. Not those names!!!

Name structures in the reproductive system. : 

Name structures in the reproductive system.

Name structures in the reproductive system. : 

Name structures in the reproductive system. In the female reproductive system: uterus, ovaries, eggs (ovum) fallopian tubes, vagina In males: sperm, testes, prostate, vas deferens, penis
