Systems and Interactions

1. Systems and Interactions

2. Integumentary Interactions • The integumentary system is responsible for protection and covering • It has two layers- the epidermis which is the outermost layer and the dermis which is the innermost layer • It consists of the skin, hair, nails, and thin layer that covers all organs • Because of it’s job protecting the body, it interacts with the circulatory system by bring blood in and out when needed. Interacts with the nervous system because of the senses (like touch). The immune system, because it is the first line of defense.

3. Circulatory Interactions • This system is responsible for delivering oxygen, nutrients, food and waste to cells within your body. • It consists of all the heart, blood vessels (arteries- which carry oxygen rich blood throughout the body, veins- which carry oxygen poor blood back to the lungs through right chamber of the heart, and capillaries- which are very small blood vessels that carry blood to hard to reach areas of the body) • Because of the circulatory systems very important job, it interacts with all of the body systems (carrying blood to all areas for cellular respiration) • The transfer of food particles, from the digestive system to the circulatory system, takes place at the inner lining of the small intestine, through millions of tiny, finger-like projections, called villi, which contain a network of capillaries. The transfer of food particles is possible because of absorption (the villi absorb the food particles from the capillaries and then transport the nutrients to the cells, to be used as fuel).

4. Nervous Interactions • Responsible for sending signals to the body from the brain (impulses that control movement, thought, and action). It acts like the control center • Consists of nerves, brain, spinal cord • It interacts with all of the systems whether voluntary or involuntary so that all of them know what’s going on in the rest of the body. • http://faculty.washington.edu/chudler/organ.html

5. Endocrine Interactions • Responsible for hormone creation and hormone control • Consists of all glands that produce hormones: thyroid, thalamus, hypothalamus, • Interacts with the reproductive system to send signals for reproduction, excretory system: kidneys, nervous system- instead of sending impulses that can only last a few seconds to minutes the endocrine system can send messages that last up to months at a time, circulatory system- the messages sent using hormones travel through the blood stream

6. Excretory Interactions • Responsible for the removal of waste products from the body • Consists of kidneys, liver, large intestine, bladder • Interacts with the endocrine system, the circulatory system, the digestive system, and the nervous system

7. Digestive Interactions • Responsible for nutrient absorption • Consists of mouth, esophagus, stomach, small intestine, large intestine, and many others • Interacts with the excretory system to remove waste after nutrients have been absorbed, nervous system- involuntarty, muscular system- most of the organs within the digestive system are made of smooth muscle, circulatory system- once food enters and is broken down- the nutrients are absorbed into the circulatory system to be carried throughout the rest of the body

8. Muscular Interactions • Responsible for movement • Consists of smooth, cardiac and skeletal muscle. Smooth muscle makes up the internal organs, cardiac muscle- makes up the heart, skeletal muscle- makes up everything else, found along the skeletal system to help with bone movement. • Interacts with the skeletal system, circulatory system, digestive system

9. Immune/Lymphatic Interactions • Responsible for fighting off disease • Consists of white blood cells, the lymphatic system • Interacts with the nervous system, integumentary system, and most other organisms

10. Skeletal Interaction • Responsible for support and protection • Consists of all bones • Interacts with the muscular system which aids in movement, the circulatory system because it is where blood is created

11. Respiratory • Responsible for bringing oxygen into the body and expelling carbon dioxide from the body • Consists of lungs, nasal cavity, diaphragm, trachea, pharynx, larynx • Interacts with circulatory system. The respiratory system exchanges oxygen and carbon dioxide, while the circulatory system transports those gases throughout the body. The interaction between these two systems happens in the tissues of the lungs. Breathing (the exchange of gases) moves air in (inhalation) and out (expiration) of our bodies.

12. Reproductive • Responsible for the creation of offspring • Consists of sexual organs and hormones • Interacts with nervous system, circulatory system, endocrine system
