ATTRACTION IN THE SYSTEM:
Digestive System: Small Intestine- chemical digestion and absorption of food eaten occurs, nutrients are absorbed through intestine wall
Excretory System: Liver- converts toxic waste into less toxic urea, then transported to the kidney.
Nervous System: Spinal Cord- main "communication link" between the brain and the rest of the body.
Skeletal System- Skull, which forms a protective "shell" around the head.
Muscular System: Skeletal muscles like the abs, biceps and triceps.
Integumetary System: Skin- the skin has 3 layers; Epidermis (outer layer of skin), Dermis (contains collagen, blood vessels, nerve endings), & Hypodermis (fat).
Circulatory System: Heart- pumps blood in & out and circulates it throughout the body.
Respiratory System: Larynx- the voacl cords; so we can talk
Endocrine System: Thyroid- regulates the metabolism throughout the body.
Immune System: Interferons- interfere with viral growth, slows down production of new virus.
The Human Body
Each system helps in maintaining homeostasis. The digestive system helps to break down food to give the body the nutrients it needs. The excretory system excretes waste from the body, such as sweat and urine. The nervous system collects information about the body and responds to it. The skeletal system assist in movement, protects the internal organs and helps with the production of blood cells. The muscular system helps with the movement of the body. The integumentary system serves as a barrier against infection, injury, regulate body temp, and removes waste. The circulatory system transports oxygen, nutrients, and other substances throughout the body. The respiratory system brings in the oxygen from the air so we can breathe. The endocrine system release hormones that deliver messages throughout the body. The immune system is the bodies second line defense against infectious disease.
Scientist have recently discovered a new way to reverse kidney failure by studying mice. The scientist used mutant mice and by feeding them probucol, a drug formerly used to treat people with high cholesterol. The probucol prevented the mice from getting kidney disease, and it reversed the disease in mice that already had it. Dr. Falk decided that if worked on mice that it may one day, with more tests, be able to help children who suffer from mitochandrial disease.
Smoking is a habit that will affect all the systems. Smoking is one of the leading causes that excelerate cardiovascular disease. It also can cause cancer, especially in the lungs, mouth, and throat that hardly ever affect non-smokers. Smoking can also cause COPD, a term of conditions that block airflow and makes breathing difficult. These conditions would be emphysema and chronic bronchitis. Smoking can also lead to higher blood pressure, which can cause hypertension. It will also cause asthma to become worse and counteract medicaation given for asthma. Smoking can affect any of the systems in the body. If not directly, then it happens by going through another system in time.
