Hello 7th grade,
Tuesdays class started off with checking if everyone did their homework. A reminder to everyone, you should keep doing your homework and not stop because it is the end of the year. Ms D also told us that we are going to dissect on Thursday and that we can decide with whom we want to work together. We then got our cell labs back. After that, we started going over the muscular system and the chapter 3 notes. After that completed the heart and the circulatory system diagrams.
Here are just some of the questions and answers that we reviewed during class.
How many muscles approximately are in the human body?
The human body has approximately 600 muscles.
What are three types of muscle tissue?
· Skeletal muscle (biceps/triceps)
· Smooth muscle (stomach/blood vessels)
· Cardiac muscle (heart)
What is a tendon?
A tendon is a strong connective tissue that attaches muscle to bone.
Section 5: The Skin
What are the five main functions of the skin?
· Protecting the body
· Maintaining temperature
· Eliminating wastes
· Gathering information
· Producing vitamin d
Uv
Gamma
X ray
IR
Visible
Radio
Microwave
Ms D also told us about this man who had a led filling in his teeth. He could hear special radio signals because of the led filling.
Chapter 3
Section 1: The Body’s Transportation System
What does the cardiovascular system include?
· Heart
· Blood vessels
· Blood
What are its main functions?
· Removing wastes (CO2 out)
· Delivering needed materials (gets O2 to cells)
· Fighting disease (NRG and nutrients C,N,O,H get to cells)
Arteries- caries red blood and nutrients to cells (from heart to body)
Veins- caries blue blood and waste from cells (from body to heart
Capillars- arteries plus veins meet= O2 nutrient exchange for waste. Most of them in lungs/ alveoli
What we learned in class relates to life because we now know more about what we have inside our body and how our body works. We can also take better care because we know what organs need.
Homework and reminders
