2 Objectives Describe the structure and function of the human _________
Trace the flow of blood through the ______ and _________ Distinguish between ________, _________ and _____________ in terms of their structure and function. Distinguish between __________ circulation and ______________ circulation Heart, heart and body, arteries, veins, capillaries, pulmonary, systematic

3 The Heart The circulatory system is made up of the _____________system and the lymphatic system. The cardiovascular system is made up of the _____________, _____________ and ____________________________. Cardiovascular, the heart, blood and blood vessels

4 The Heart The _________ is the central organ of the cardiovascular system. heart

5 The Heart Some of the important parts of the heart include:
________________ The septum, atrium and ventricles

6 The Heart: The Septum Septum: separates the heart _________ into two sides. Vertically

7 The Heart: The Atrium The Atrium: is the _______chamber of the heart
The Right Atrium: receives ________ blood that is __________ to the heart Upper, deoxygenated, returning

8 The Heart: The Ventricle
The Ventricle: is the ___________chamber of the heart The Right Ventricle: pumps __________ blood ______ of the heart. Lower, deoxygenated, out

9 The Heart: Valves The valves are flaps of ________ that control the flow of the _______ They prevent _________ flow in the _______ Tissue, fluid, backward, veins

11 Diagram of the Heart

12 Circulation of the Heart
Blood flows in the following order ___________ __________ _______________ _______________ _____________ (gas exchange) _______________ ________________ ______________ Rest of the __________ Right atrium (D) Right ventricle(D) Pulmonary arteries(D) Lungs Left Ventricle (O) Aorta (O) Body(O) WORKSHEET

13 Circulation of the Heart: The Right Atrium
Path of blood as it circulates through the heart: _____________ blood enters the _______ _________ The right atrium sends ___________ blood into the ____________ _____________ Deoxygenated, right atrium deoxygenated right ventricle

14 Circulation of the Heart: The Right Ventricle
The muscles of the ________ __________ contract and force blood into the _________________ ___________ Right Ventricle, pulmonary arteries

15 Circulation of the Heart: The Lungs
The ___________ artery sends blood to the _________ In the lungs: _____________diffuses out of the blood ___________diffuses in Pulmonary artery, Lungs, carbon dioxide, oxygen

16 Circulation of the Heart: The Left Ventricle
The muscular walls of the ________ _________contract and force blood into a large blood vessel, called the ________ The Aorta: carries blood from the _____ ventricle to the rest of the __________ Left ventricle, aorta, body

17 Flow Chart of Blood Flow

18 The Heartbeat The heart contracts its muscle cells in __________
The first group of heart-muscle _________ The second group of hear muscles cells ______ Waves, contracts, relaxes Regular: Irregular:

19 Control of the Heartbeat
A heartbeat has _____ phases: Phase One: _________ Phase Two: _________ Two, Systole, Diastole

20 Control of the Heartbeat: Phase One
Phase One, or _________ : occurs when the ventricles ___________. This then pumps blood _____ of the heart Systole, contract, out Mention, not responsible Squeezing balloons filled with water in a beaker???

21 Control of the Heartbeat: Phase
Phase two , or _________ and occurs when the ventricles ________. This This allows the _______ pressure of the blood. Diastole, relax, back Mention, not responsible

22 Control of the Heartbeat
The contractions in the ______ __________forces blood through the _______ A series of pressure waves results, called a _________ Left ventricle, arteries, pulse TAKING PULSE ACTIVITY (cardio work, where can you take your pulse??) -LAB

23 Blood Vessels The circulatory system is known as a _________system.
This is because the blood is contained within either the ____________ or __________ __________at all times. Blood Vessels include: _______________ _____________ ________________ Closed, heart, blood vessels, arteries, veins and capillaries

24 Blood Vessels The blood vessels that are part of the human circulatory system form a vast network to help keep the blood flowing in _____ direction. One Remember veins have valves

25 Arteries The large, muscular vessels that carry blood _______ from the heart and to the body are called _________ Away, arteries

26 Blood Vessels As the heart moves the blood through the __________, it produces a great force against the inside walls of a blood vessel. This force is known as ______________ Arteries, blood pressure

27 Blood Pressure High blood pressure, or ___________, can place a strain on the walls of the arteries and could cause that artery to __________ or __________ Hypertension, clog, burst

28 Arteries and Blood Pressure
Blood Pressure is determined by measuring: _________ pressure __________pressure Systolic pressure, measured ______, is the pressure of the blood when the ventricles ___________ Diastolic pressure, measured _______ indicates the steady flow of blood through the _________ Systolic, diastolic, first, contract, second, artery ANY ACTIVITY WITH BLOOD PRESSURE??

29 Veins After cells interact with the blood, the blood goes back to the ________ Veins: blood vessels that carry blood ______ the heart. Heart, to

30 Arteries Arteries and veins are both made up of _________ layer

31 Capillaries Capillaries: the __________ of the all the blood vessels, only _______ cell thick, carries blood: Connecting the ___________ and __________ The capillaries are a vast network of tiny vessels that allow an exchange between the _________ and the _______ to occur. The capillaries allow for the exchange of __________ and __________ Capillaries, tiny, blood and cells

32 Blood Vessels Pictures
Worksheet Veins: Blood flows to the heart Arteries: Blood flows away from the heart 3 parts of each (Draw) Purpose of capillaries

33 Cardiovascular System and its Two Subsystems
The heart and blood vessels work together to form a continuous, ________ system of circulation. This system contains two subsystems: ___________circulation ____________circulation. Closed Pulmonary Systemic

34 Pulmonary Circulation
Pulmonary circulation is the circulation of the blood as it travels between the _______ and _________ Pulmonary circulation brings the _____________blood that comes into the heart to the ________, and returns __________ blood back to the heart for distribution to the _________ Flow of blood: __________ →______________→____________ Heart, lungs, deoxygenated, lungs, oxygenated, body HEART LUNG HEART

35 Systemic Circulation Systemic circulation is the circulation of the blood between the heart and all other ________ tissues. Systemic circulation has several subsystems: __________ circulation (related to the heart) __________circulation (related to the liver) ___________ circulation (related to kidneys) Body, coronary, hepatic, renal Not responsible
