Heart










Coronary arteries:
- It needs oxygen -rich blood to survive
-blood is supplied to the hearty by its own vascular system called the coronary circulation
- aorta branches off into 2 main coronary blood vessels
- these coronary arteries branch off into smaller arteries which supply oxygen-rich blood to the entire heart muscle
- right coronary artery supplies blood mainly to right side of heart, right side is smaller because it pumps blood only to lungs
- left coronary artery branches into left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart
-left side is larger and more muscular because it pumps blood to the rest of the body












































STRUCTURE
FUNCTION
DEOXY/OXY BLOOD
LEFT ATRIUM
collects oxygen-rich blood returning from the lungs and then forces it through the mitral valve and into the left ventricle
OXY BLOOD
LEFT VENTRICLE
largest and strongest chamber in heart, wall 1/2 inch thick but strong enough to force push blood through aortic valve and into your body.
DEOXY BLOOD
RIGHT ATRIUM
collects oxygen-poor blood returning from the body, then forces it through the tricuspid valve and into the right ventricles
OXY BLOOD

RIGHT VENTRICLE
collects oxygen-poor blood from right atrium and then forces it through pulmonary valve and into lungs.
DEOXY
PULMONARY ARTERY
carries blood into the lungs and picks up oxygen

DEOXY BLOOD

AORTA
largest artery, carries oxygen-rich blood from lungs back to heart.
OXY BLOOD

PULMONARY VEINS
carries oxygen-rich blood from lungs back to the heart.
OXY BLOOD
SUPERIOR VENA CAVA
oxygen-poor blood from the upper parts of the body returns to the heart the superior vena cave
DEOXY BLOOD
INFERIOR VENA CAVA
oxygen-poor blood from the lower parts of the body returns to the heart through the inferior vena cava
DEOXY BLOOD
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
controls blood flow from the left atrium into ventricle
OXY BLOOD
CHORDAE TENDINAE
cord like tendors that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
OXY BLOOD
SEMI LUNAR VALVES (Pulmonary & Aortic)
controls blood flow from the right ventricle into pulmonary arteries
DEOXY BLOOD
SEPTUM
wall of muscle called septum separates left and right atria and left and right ventricles.

welcome to human kinetics coop 12 this is me






I have never  taken a coop class before but I have friends who did take the coop we had last year here at Sullivan, and it looked fun so this year I decided to take the coop. It seemed like an interesting course and lots to do in it. I took the coop to get a different feel of some classes and learn new things other than what we have. my plans for after high school are to go to Sauder and get my license for real estate and mortgage breaking and then go to sfu and take business classes then get a degree in something in the business field. when I am not in school I like to sit around and watch t.v., go for walks, sleep, and go on the computer. over the summer I got really lazy and never wanted to do anything but I did get some exercise in while I sat around sometimes. over the semester I wish to become more active and play more sports. hopefully this course will teach me lots more and be a different experience than what I have already experienced in my regular classes.
