1Circulation and Respiration Chapter 2 Vocabulary Cardiovascular System Heart, Bloodand Blood VesselsVeinArterycarries bloodto the heartblood carried awayfrom the heart
2Section 1: The Cardiovascular System PulmonaryCirculationSystemicCirculationblood flows from theheart to the lungsand back to theheartblood flows from theheart to all parts ofthe body and backto the heart
3The Cardiovascular System Section 1The Cardiovascular SystemThe heart is the organ mademostly of cardiac muscle.HeartThe Cardiovascular System:1. Helps maintain homeostasis.2. Helps in regulation by chemical signalscalled hormones.cardiac1. What is the Heart muscle called?_____________ligament
4Veins: Vein carries blood to the heart Valves in the veins keep the blood from flowing backward.1. Veins keep the blood flowing.2. Veins carry blood to the heart.1. What carries blood to the heart?_____________veinsoxygenClick on the blue button to watch a video on the Heart.
5Arteries have thick walls that contain muscle. blood carried awayfrom the heartArteryArteries:Arteries have thick walls that contain muscle.1. Artery walls stretch.2. Arteries are strong to stand pressure.1. What do the walls do in the artery?________________stretchbreakstrong2. Arteries stand pressure because they are?___________________weak
6Section 2: Blood Blood Blood Pressure fluid that carries nutrients and wastesforce of blood
7Blood fluid that carries nutrients and wastes The fluid part of the blood is called Plasma.Plasma contains:1) Red blood cells2) White blood cells3) PlateletsRed blood cells take oxygento every cell in your body.Red Blood CellsHemoglobin is an oxygen-carrying protein.Platelets are pieces of larger cells found in bones.White blood cells keep you healthy by destroying pathogens.Click on blue button to watch a video on blood and platelets.
8Blood pressure is given as two numbers: force of bloodBlood pressure cuffBlood pressure is given as two numbers:Systolic: 1st number: is the pressure inside large arteries when the ventricles contract.Diastolic: 2nd number: is the pressure inside arteries when the ventricles relax.Each person has one of four blood types: A, B, AB, OClick on the blue button to watch a video on the heart.
9Section 3: The Lymphatic System The Lymphatic System collects excess fluid and returns it to your bloodstream.Bone MarrowTonsilssoft tissue insidethe bonelymphatic tissue at the backof the mouth on eitherside of the tongue
10Most red and white blood cells are produced in your bone marrow. soft tissue insidethe boneBone MarrowMost red and white blood cells are produced in your bone marrow.Bone marrow is located inside the bone.1) Where is bone marrow located?_________insideoutsideblood cells2) What is produced in the marrow?_________lymph nodesClick the blue button to watch a video on how the blood pumps.Click the blue button to watch a video on red blood cells.
11Tonsils help the body defend against infection. lymphatic tissue at the backof the mouth on eitherside of the tongueTonsilsTonsils help the body defend against infection.Sometimes tonsils can become sore and swollen.If a child has frequent infections or has enlarged tonsils, a doctor will remove the tonsils.1) What helps your body against infection?_______________tonsilshealthy eating
12Section 4: The Respiratory System The process where the bodygets oxygen and releasescarbon dioxideRespirationPharynxThroatThe part of the throat thatcontains the vocal cordsLarynxThe tube that connectsthe larynx to the lungsTrachea
13Respiration Breathing: Inhaling & Exhaling Cellular Respiration The process where the bodygets oxygen and releasescarbon dioxideRespirationBreathing: Inhaling & ExhalingCellular Respiration- You need to breathe to live.- Chemical reactions that release energy from food.1) What do you need to live?________________breathinga dog2) What do you inhale?______________oxygencarbon dioxide3) What do you exhale?____________carbon dioxideBlowing up a balloonis exhaling.oxygen
14PharynxThroatFood and drink travel through the pharynx on the way to the stomach.A) The pharynx branches into two tubes.B) One tube is the esophagus and the other is the larynx.C) The esophagus leads to the stomach.D) The larynx leads to the lungs.esophagus1. What tube leads to the stomach?_____________lungs
151 Larynx The part of the throat that contains the vocal cords The vocal cords are a pair of elastic bandsthat stretch across the larynx.A) Muscles connected to the larynx control howmuch the vocal cords are stretched.B) When air flows between the vocal cords,the cords vibrate.C) These vibrations make sound.Click on the blue button to watch a video on sound.1) Why do vocal cords vibrate?____________air flowlarynxliquid flow2) What makes sound?______________vibrationselastic bands
16Trachea The Trachea is also known as your windpipe. The tube that connectsthe larynx to the lungsTracheaThe Trachea is also known as your windpipe.A) Your body has two, large spongelike lungs.B) The trachea is the passageway for airtraveling from the larynx to the lungs.1) What is the passageway for air?____________________tracheaesophagus2) the trachea is also known as the?___________________windpipeesophagus
