Daily Catalyst Class Business Heart rate lab Circulation notes Finish heart rate lab 4/29 Agenda Pg. 63 Circulatory

 Discuss the structures and functions of the circulatory and respiratory system and how they work together to maintain homeostasis. 4/29 Objective

 1. What are the functions of the circulatory and respiratory system?  2. What are the major organs we need to know?  3. How do we keep our lungs and heart healthy? Essential Questions

Heart Catheterization

 catheterization catheterization

 Cardiovascular Write me down! HEART VESSELS

 Directions: Pair up with a partner.  Open up your body packet to the Heart rate lab  Read the directions  Create a hypothesis as a pair and identify the IV and DV  Time: 8 minutes  Noise: 1 (with partner) Heart Rate Lab

 Directions: Complete the chair sit lab. You will measure heart rates before and after physical activity to demonstrate how the cardiovascular and respiratory systems work together.  Time: 6 minutes  Noise: 1 (with partner) Lab

 Key Point #1: Function  Transport nutrients, gases, and wastes throughout the body. The function of the circulatory system

 Who is the transporter of the body?

The Transporter BLOOD!!

Blood delivers materials in the body Aorta Arteries Arterioles Capillaries Venules Veins Vena Cava

 Key Point #2: Main organs  Heart  Blood  Blood Vessels The anatomy of the circulatory system

 1. Heart:  Muscular organ  Pumps blood through 4 chambers  Size of your fist  Beats about 72 times per minute at rest and about 100,000 times per day The Heart

 2. The Blood:  Made of plasma, platelets, red blood cells and white blood cells  Carries nutrients and gases  The heart pumps 2,000 gallons of blood per day The Blood

 3. Blood Vessels:  Tubes that transport blood  Arteries:  Veins:  Capillaries:  The blood travels 60,000 miles through blood vessels a day The Blood Vessels

 A rteries: Carry oxygenated blood AWAY from the heart to the body  Ve in s: Carry deoxygenated blood IN to heart and lungs to receive oxygen  Capillaries: Exchange oxygenated blood for deoxygenated blood  * this is where the veins and arteries connect* The Blood Vessels Continued

 Blood enters the heart in the right atrium and travels to the right ventricle  Blood pumps to the lungs to get oxygen  Oxygenated blood enters to left atrium and the left atrium where it is pumped out of the heart to the body Organ spotlight The Heart

Carries blood away from the heart ARTERIES A=arteries V=veins

Carries deoxygenated blood VEINS A=arteries V=veins

Site of oxygenated and deoxygenated blood exchange The capillaries

Major transporter of nutrients and gases The blood

Pg. 65 Respiratory System

Key point #1: Heart Rate  Heart beats per minute  bpm Heart rate measures how fast blood is moving through your body. Heart rate

What is a normal resting heart rate?  Average adult bpm  In shape bpm  Good athlete bpm  Excellent athlete <50 bpm

Michael Phelps’ resting heart rate is in the 30s!!

Michael’s heart rate is about 50 beats per minute During a slow warm-up swim…

What about when Michael races? Michael’s heart rate after a race increases to about 200 beats/min

Why does heart rate increase after activity? So…. BACK TO NOTES!

 Key Point #2: Function  To exchange the Oxygen (O2) for Carbon Dioxide (CO2)  Breath in O2  Breath out CO2 The function of the Respiratory System:

When someone does physical activity, their cells need ENERGY! They must go through cellular respiration. Back to the cell… Blood delivers oxygen to cells for respiration Blood takes away the CO2 waste from respiration Key Point #3: Cellular respiration is the process that produces energy (ATP)

Back to the cell… Blood delivers oxygen to cells for respiration Blood takes away the CO2 waste from respiration Key Point #4: More activity means the cell needs more OXYGEN!

The Respiratory System  Cells release CO2 in the blood during respiration. There is no CO 2 in the lungs so it diffuses out of the blood and you breathe it out.  The O2 you breathe in diffuses into the blood because there is a lot of CO 2 in the blood and not a lot of oxygen. Key Point #5:O2 and CO2 diffuse in and out of the body

Review: Diffusion Diffusion means to GO from ? to ? It requires no ENERGY! (Passive transport)

 Flow of molecules  Key Point #6:  Nose & mouth  larynx  trachea  bronchi  alveoli The anatomy of the respiratory system

 Key Point #7: the alveoli are the function unit of the respiratory system  ‘Grapes”



 1. Nose & Mouth  Takes in and filters air ORGAN SPOTLIGHT! Nose

 2. Trachea  Tube that carries oxygen from the nose to the lungs ORGAN SPOTLIGHT!

 3. Bronchi  Branch into lungs from trachea ORGAN SPOTLIGHT! Bronchi

 4. Alveoli  tiny air sacs  “grapes”  Site of oxygen and CO2 exchange ORGAN SPOTLIGHT! Alveoli Alveoli

Tell me what ya know!

Carries nutrients to your body CIRCULATORY C= circulatory R=respiratory

Breathes out CO 2 RESPIRATORY C= circulatory R=respiratory

 This is the site of O2 and CO2 exchange in the respiratory system  The alveoli  This is the site of O2 and CO2 exchange in the cardiovascular system  Capillaries C= circulatory R=respiratory

 Oxygen and carbon dioxide are exchanged in the ALVEOLI through the respiratory system  The circulatory system transports nutrients, gasses, and wastes to where they need to go in the body  The circulatory and respiratory system work together to maintain homeostasis in your body by keeping the right balance of gases in your body Review
