2. How many miles per day does blood travel in the body?

3. True or False? A pint of blood is equivalent to a pound, so people lose a pound when they donate blood.

4. Use 2 fingers to find your heart rate or pulse at your carotid artery. Record the # of beats you observe in 30 seconds!

Unit 5: Human Body Systems

Agenda

• Catalyst 5

• Vision Refresh 5

• Circulatory Intro 15

• Heart Rate Lab 15

• Pathways Drafts 10

ObjectivesWe are learning about…

the circulatory systemWe will be successful when we

can…explain how the circulatory system

transports nutrients & oxygen to cells & removes cell waste

arteries & veins

Heart iNtRoSize of a fist…Located slightly left of center in

chest

FiNd yOuRs!Made of cardiac muscle3 main functions:

1. Delivers oxygen to cells2. Delivers nutrients to cells 3. Removes waste from cells

Heart aNaToMy

4 chambers:

1. Right atrium2. Right ventricle3. Left atrium4. Left ventricle

12

Heart PaThWaYsSuperior vena cava: blood

from parts of the body above heart

Inferior vena cava: blood from parts of the body below heart

Blood returning to heart & entering right atrium is loaded with carbon dioxide (CO2)

COLOR the veins and the right atrium BLUE!

1What veins lead to this chamber?

Heart PaThWaYsTricuspid valve: opens and

closes to allow one - way blood flow

Ejects used blood through to the left pulmonary artery

toward the lungs

Blood here is loaded with carbon dioxide (CO2)

COLOR the right ventricle & pathway to the lungs BLUE!

2Where does blood pass to enter this

chamber?

Heart PaThWaYs

Receives oxygen-rich blood from the lungs via the left pulmonary veins

Blood here is loaded with oxygen (O2)

COLOR the veins & left atrium RED!

3Where does blood get oxygenated?

Heart PaThWaYs 4What does the bicuspid valve do?

Bicuspid valve: opens and closes to allow one - way blood flow

Largest chamber & strongest pump

Discharges blood into aorta through the aortic valve

From the aorta, all body tissues receive oxygen-rich (O2) blood

COLOR the left ventricle and aorta RED!

Heart sOuNdS“Lub Dub”

Tricuspid & bicuspid valves open and close simultaneously.

The closing of these two valves is the "Lub" sound heard through the stethoscope.

Pulmonary & aortic valves operate at the same time.

The "Dub" sound heard is the closing of these valves.

Quick Check!1. What are the 3 main functions of the circulatory

system?

2. Where does the heart pump oxygen-rich blood?

3. Where does the heart pump oxygen-poor blood?

4. How many chambers are there in the heart?

5. What is an UPPER chamber of the heart called?

6. What is a LOWER chamber of the heart called?

AV

Heart Rate LabQuestion: When your body works hard during exercise, your cells need more oxygen and nutrients, and they make more carbon dioxide and other waste. How does your circulatory system respond to these changes?

Hypothesis: I think that when my body works hard during exercise, my circulatory system responds by___________________________________

* Finding your carotid artery*Use 2 fingers (index & middle finger) to find the “corner” of your jaw and move your fingers slightly down & forward.Press lightly until you feel a pulse.

Pathways Journal 8minute

s!

Imagine you are a red blood cell traveling through the circulatory system. Write a journal entry using bullet points to describe your journey through the heart & lungs using the following

vocabulary words:

 Make sure your journal entry includes the pathway through all 4 chambers of the heart.

Circle all of the vocabulary words!

• Heart• Atrium• Ventricle

• Blood• Oxygen

•Carbon Dioxide
