Structures, Functions, and Interactions

Structures: bones, cartilage, joints, marrow Functions: provides shape and support, enables you to move, protects your internal organs Interactions: bones make your red blood cells (cardiovascular).

 An adult has 206 bones and a baby has over 300 bones!  The strongest stuff in your body isn’t bone…it’s tooth enamel!  Bone is stronger than concrete!

Structures: skeletal muscle, smooth muscle, and cardiac muscle Functions: Involuntary muscles are responsible for activities such as breathing and digesting food; Voluntary muscles are under your control Interactions: All systems b/c all of your organs are made of muscle

 Your body has about 650 muscles!  The strongest muscle in your body is the biting muscle in your jaw!  The biggest muscle in your body is your gluteus maximus…your rear end! (You have two of these, one for each leg)

Structures: brain, spinal column, nerves. Functions: detects & interprets info from inside and outside the body; control center Interactions: Tells muscles to contract (voluntary), tells heart to pump (involuntary)

 Each neuron can transmit up to 1,000 signals each second!  The biggest part of your brain is your forebrain. It includes your cerebrum… This lets you think, imagine, plan, learn, remember, speak, understand language, and do all the other things you do!

Organs: glands such as hypothalamus, thyroid, ovaries, testes Functions: Controls body functions by using chemicals from glands Interactions: Sends growth hormones to skeletal system, releases adrenaline into the blood stream to stimulate the muscles into action.

1. The _______ and _________ muscles are involuntary muscles while the ___________ muscle is voluntary. 2. The ___________ system is responsible for making red blood cells. 3. Adrenaline is produced by the _________________ system. 4. The ______________system is the control center for the body. smoothcardiac skeletal endocrine nervous

Structures: Structures: Mouth, esophagus, liver, stomach, gallbladder, pancreas, large intestines, small intestines, rectum Function: Function: breaks down food into molecules the body can use, and eliminates waste Interactions: Interactions: Uses the circulatory system to take food to the individual cells, forms the end of the excretory system to expel solid waste.

 If you got pure stomach acid on your skin, it would hurt. Your stomach has a lining of mucous on the inside to protect itself from the acid.  It takes about 24 hours from eating to eliminating solid waste from the body.  Some animals — including seahorses, lungfishes and platypuses — have no stomach. Their food goes from the esophagus straight to the intestines.

1. Story is written from the perspective of a cheeseburger. (5 points) 2. Story describes in detail what happens in each of the following organs: Mouth, pharynx, esophogous, stomach, small intestines, and large intestines. (5 points each organ) 3. Story also mentions the functions of the liver, pancreas, and gallbladder. (5 points each)

Use your directed reading to answer the following: 1. Give an example of mechanical digestion. 2. What is the job of the esophagus? 3. Where does chyme go when it leaves the stomach? 4. Why is the small intestine called “small”?

Organs: Tonsil, Spleen, Thymus, Lymph Nodes Function: returns leaked fluids to blood vessels and helps get rid of bacteria and viruses. Interactions: White blood cells made in the bones grow into T cells in the thymus.

Organs: Skin, Hair, Nails Functions: Protects, keeps water in, foreign particles out, allows you touch, regulates temperature, gets rid of wastes Interactions: Works with the nervous system to keep you aware of your surroundings.

Structures: Large Intestines, rectum, anus Functions: Material that cannot be absorbed into the blood stream is compacted in the large intestines for elimination. Interactions: The large intestine absorbs water into the cardiovascular system for use throughout the body.

Structures: kidney, urinary bladder, urethra Functions: Blood is filtered through the kidneys to remove cell/body waste. Waste is stored in the bladder and eliminated as urine. Interactions: Cleans waste from the circulatory system.

Structures: Nose, Lungs, Wind Pipe Function: Moves oxygen into the body and removes carbon dioxide and water from the body. Interactions: Circulatory system carries oxygen to the cells and carbon dioxide away.

Structures: Heart, blood vessels Functions: Heart pumps blood through all blood vessels. Interactions: Highway system of the body, carries food (digestive) and oxygen (respiratory) to the cells and carries waste away.

Structures: Testes, ovaries, and uterus Function: Create a new living individual Interactions: The endocrine system regulates the hormones necessary for sexual maturity and reproduction.
