BROWN

Human Body Study Comprehensive Exam: 11/17/2011

(Quiz Date- 10-25) Respiratory system- All the parts to the body that work together to breathe in oxygen and breathe out carbon dioxide is the respiratory system

· Why do we breathe faster when we exercise? We need to supply our muscles with enough oxygen and to get rid of waste, carbon dioxide. Just as a burning log gives off heat and light energy, the cells in your body produce energy by breaking apart sugar. Cells need energy to perform chemical reactions and work properly. For energy production to take place, cells need oxygen.

· The diaphragm helps us move air in and out of the lungs. When we inhale, the diaphragm contracts or pushes downward and flattens, and when we exhale the diaphragm relaxes and returns to its dome shape.

· The epiglottis closes and shuts like a trapped door. It is located at the bottom of the throat and behind the trachea. When we swallow the epiglottis, it flips down automatically to keep food from going down the trachea.

· Bronchial tubes are located at the bottom of the trachea and branch off into many smaller branches.

· When we try to hold our breath, the brain detects the increase in carbon dioxide levels, signaling the lungs to inhale and exhale.

(Quiz Date: 10-28) Circulatory System

· The heart pumps blood through the veins, arteries, and the capillaries.

· It is responsible for bringing oxygen and nutrients to all the cells in the body from the respiratory and the digestive system.

· It takes carbon dioxide and waste away from cells.

· The arteries carries Oxygen rich blood and the veins carry carbon dioxide and other waste away from the organs and back to the lungs for exhale and to the kidneys for fluid waste.

· Arteries are red and veins are blue

· The capillaries are tiny tubes that connects the arteries and the veins

(Quiz Date- 11-2) Urinary (Excretory) system

· This is the system that filters or cleans the blood of waste.

· Parts of the Urinary system: Two Kidneys, ureter, bladder, and urethra.

· As blood flows through the kidneys, some water, sugars, salts, and the nitrogen wasted called urea are removed from the blood. The removed substances flow up and down long tubes inside the kidneys. As they do, the blood absorbs back all the sugars, salts, and water the body needs. The clean blood flows back out of the kidneys. The waste flows as urine into collecting ducts called ureters to be stored in the urinary bladder. The urinary bladder is a muscular bag that has a ring of muscles at the bottom that holds the bladder tightly shut. Urine filling the bladder stretches the bladder wall causing the wall nerves to signal the brain that the bladder should be emptied. Each day the kidneys produce about a quart of urine each day.

· About 70 percent of the human body is water. Blood and saliva are mostly water. There is water in cells and in between cells in tissue fluid.

· It is important for you to drink enough water each day to replace the water lost in urine, sweat, and in the water vapor given off when exhaling.

(Quiz- 11-4) Endocrine System

· Endocrine system consists of glands. A gland is and organ that sends chemical messengers called hormones to other parts of the body. Hormones are “dumped” into the blood and are carried to where they are needed. The body produces over 50 different types of hormones. Endocrine glands are throughout the body: Thyroid gland (in the neck)- controls the body’s metabolism or how the body provides energy. Adrenal Glands- (above the kidneys) are involved in the body’s reaction to dangerous or frightening situations. The pancreas- (in the abdomen) maintains blood sugar levels.

(Quiz- 11-8) Nervous system

· The nervous system sends messages to the brain. The brain interprets the message and sends a new message to muscles throughout the body.

· It controls how the body acts and moves

· The nervous system is made up of specialized cells call neurons.

· Neurons send and receive messages in the form of electrical impulses. They act like electric wires, although the impulses they carry are very different from electricity.

· The brain is the central organ of the nervous system. I

· The human brain is composed of 100 billion neurons.

· Extending the brain is a thick cord of nerve cells call the spinal cord.

· The spinal cord is protected by a thick series of bones called the vertebra. These thick bones make up your vertebrae

(Quiz- 11-15) Muscular and Skeletal System-

· 3 types of muscle tissue- Smooth, cardiac, skeletal. Smooth muscles are involuntary muscles because they contracts without your control. Cardiac Muscles- found only in the heart and are also involuntary. Skeletal Muscles- are voluntary muscles and are attached to the bone. They pull on the bone and move them. Skeletal muscles help shape the body and protect its internal organs.

· Blood cells are produced in the bone marrow, a jellylike substance inside the bones that is composed of, among other things, fat, blood, and special cells that turn into the various kinds of blood cells. In children, the marrow of most of the bones produces blood. But in adults, only the marrow of certain bones -- the spine, ribs, pelvis, and some others -- continues to make blood. Bone marrow that actively produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.

· The different kinds of blood cells have different "life spans" -- red blood cells last about 120 days in the bloodstream; platelets about 10 days; and the various kinds of white blood cells can last anywhere from days to years.The body has a feedback system that tells it when to make new red blood cells. If bodily oxygen levels are low (as they would be if there are too few red blood cells circulating), the kidneys produce a hormone called erythropoietin, which stimulates the stem cells in the marrow to produce more red blood cells.

Digestive system (Quiz Already Taken)

· Digestive system begins in the __________________. 6 salivary glands (three on each side of the mouth) help soften and moisten chewed food. The _______________pushes small balls of food to the back of the mouth into the throat. As the food goes down the esophagus, the ________________opens to allow the food to travel down the stomach. It takes 4-6 seconds for the food to travel to the stomach. Acids in the stomach such as hydrochloric acid helps break down the food. Then the food goes into the small ______________, which is about 21 feet long

· It can take 10-20 hours for food to pass from one end of the digestive system to the other.

· The liver is the largest organ inside the human body. It stores vitamins and mineral, makes important proteins, and destroys worn-out blood cells.

· The appendix it the fingerlike projection at the beginning of the large intestine. No one knows what the appendix does, but if the appendix enlarges or becomes infected, it must be removed.

· Helpful bacteria live in the large intestine to produce vitamins people need.

· Eating foods high in fiber are important for the large intestines. Fiber helps the intestine work properly, preventing constipation.

· Some medicine can cause vomiting, diarrhea, stomach cramps, or constipation. Too much caffeine or nicotine can cause stomach to over produce acid causing ulcers and too much alcohol can permanently damage the liver.

(Quiz Already Taken) The Epidermis (Our Skin) largely part of the Integumentary system

Our skin the largest organ of our body. It weighs ________ as much as our brain. Three layers of skin: Epidermis (outer layer), Dermis (middle layer), and the subcutaneous or hypodermic (lower layer). Dermis means true skin. Epi means above, and hypo means below. Our skin helps us to detect, temperature, pain, and pressure. Our skin has nerve endings that send electrical signals to the brain.
