Relating to structures of the body and nutrition

Young people can’t get heart attacks

• While the risk of heart attack rises with age, teens and young adults can have heart attacks.

• Risk factors that are controlled early in life make it less likely to persist later in life

• The lesson is that just because someone is not “old” that does not mean that symptoms such as chest pain and shortness of breath are not signs of a heart attack.

If one of my organs fail I can just get a transplant.

• The waiting lists to receive transplants are very long.

• Depending on your age and overall health you may not receive one.

• The best organs are the ones you already have.– New ones might not be complimentary to your body

You can only get diabetes if you eat too much sugar

• Type 1 diabetes is caused by genetics and unknown factors that trigger the onset of the disease.

• Type 2 diabetes is caused by genetics and lifestyle factors. Being overweight does increase your risk for developing type 2 diabetes, and a diet high in calories, whether from sugar or from fat, can contribute to weight gain.

• Eating a healthy meal plan and regular exercise are recommended to manage your weight.

0g of fat means that the food/drink is healthy

• Not necessarily.• A nutrition label may have

0g of fat on it but have an excess amount of calories.

• If you consume an excess amount of calories it will turn into fat.

disorders of the accessory organs and diabetes

• The digestive system and cardiovascular system and their disorders.

Dry Lab: Cardio-Respiratory Investigation

• Since this is an introductory activity, make sure you stress the connections between the previous topics and new topics

Wet Lab: Rat Dissection

• Some things to remember when teaching dissections:– Understand and communicate the value of dissections– Be able to provide alternatives for students who are

uncomfortable– Have proper equipment and address any allergies (i.e. latex)– Ensure that you only have exactly as much equipment out as

you need– Encourage a clean and neat dissection environment so that

specimen can be used later…for a bell ringer perhaps– Allow students to circulate and see one another’s dissections

• Some specimen may have better organ systems than others

General Dissection Rules

• #1 RULE: RESPECT THE RAT• Don’t cut more than is necessary• Reminder: Wear your gloves! • You are using SHARP instruments, be careful!– Carry with blade down– When cutting with scissors, angle slightly up so

you don’t cut the other organs• If you have ANY questions…ASK!!!
