30.1 Circulatory Functions Set up Cornell Notes on pg. 73 Topic: 30.1 Circulatory Functions Essential Question(s): How do the respiratory and circulatory systems help maintain homeostasis in the body? Arteries and veins are equally distributed throughout the body. How does this arrangement help to maintain the functions of each cell? 30.1 Circulatory Functions 2.1 Atoms, Ions, and Molecules

How does your heartbeat and breathing rates change as you go from a walk to a run? In your experience, what factors may have interfered, making your breathing more difficult?

How does your heartbeat and breathing rates change as you go from a walk to a run? They increase. 2) In your experience, what factors may have interfered, making your breathing more difficult? Being out of shape High Altitude Asthma Extremely Hot/Cold weather Allergies Respiratory infection Second-hand smoke or because you ARE a smoker Pollution Chemical fumes disease

KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.

brings supplies to cells carries away wastes The respiratory and circulatory systems work together to maintain homeostasis. The circulatory system transports blood and other materials to and from cells brings supplies to cells carries away wastes separates oxygen-poor and oxygen-rich blood Oxygen-poor blood Oxygen-rich blood

There are three major functions of the circulatory system. 1) transporting blood, gases, water, and nutrients to cells 2) collecting waste materials (CO2) 3) maintaining body temperature

On pg. 72 create a bubble map of the Circulatory System arteries Pg. 910-915 in book veins Circulatory System Red blood cells hemoglobin capillaries heart You need a description and picture for each

heart pumps blood throughout body The system includes : heart pumps blood throughout body arteries move blood away from heart Oxygen-rich blood veins move blood back to the heart Oxygen-poor blood capillaries get blood to and from tissues *Where gas, water, and nutrient exchange occur Blood Vessels

red blood cells- pick up oxygen in the lungs and delivers it to all the body cells; picks up CO2 O2 binds to hemoglobin- gives blood its reddish color Blood becomes bright red only when it absorbs oxygen

Video Notes Add information to your bubble map from the video. You need to add AT LEAST 2 more pieces of information to each part of the bubble map

Capillaries Bronchi and Bronchioles

How does the respiratory and circulatory system interact? Think: What does the respiratory system bring into your body? How does the circulatory system distribute that product? What waste product does the blood pick up from the cells? How does our body get rid of that waste?

The lungs bring oxygen into the body How does the respiratory and circulatory system interact? The lungs bring oxygen into the body the circulatory system (blood stream) carries that oxygen to all of the body’s cells. The blood stream also picks up cells’ waste (carbon dioxide) expels that waste as carbon dioxide when we exhale (breathe out).
