2 CARDIOVASCULAR SYSTEM Function – Deliver oxygen, nutrients and hormones to various body tissues and transports waste porducts to the appropriate waste removal systems.Sometimes called the circulatory system.
3 Heart – cardi/o Provides the power to move blood through the body. Located inside the thoracic cavity – chest cavityLies between the lungs in a cavity called the mediastinum.Mediastinum also contains large blood vessels, trachea, esophagus, lymph nodes and other structures.Pericardium – Double walled membrane surrounding the heart.Heart WallsEpicardium – external layer of the heart.Myocardium – Middle and thickest layer of the heart – actual heart muscle.Endocardium – Inner layer of the heart – lines the heart chambers and valves. Note – end/o means within.
4 Heart ChambersHeart is divided into left and right sides. The right and left sides are further divided into chambers.Mammalian and avian hearts have 4 chambers.Reptile hearts have 3 chambers.Atrium/Atria – atri/oAll vessels coming into the heart enter here.Craniodorsal chambers of the heartVentricles – ventricul/oCaudoventral chambers of the heart.Pumping chambers of the heart and all vessels leaving the heart leave via the ventricles.Atria Ventricles
5 Heart Sounds Auscultation using a stethescope. Hear a “lubb/dubb” sound.Lubb = first sound heard. Caused by closure of the AV valves (atrioventrical valves)Dubb = second sound heard. Caused by closure of the semilunar valves.Systole (ventricular contraction) – occurs between the first and second heart sounds.Diastole (ventricular relaxation) – occurs between the second and first heart sounds.Murmur – Abnormal sound associated with the turbulent flow of blood. May be caused by a leak in a valve.
6 VESSELS Three major types Vessel – angi/o vas/o Artery – arteri/o Arteries, veins and capillariesVessel – angi/o vas/oArtery – arteri/oBlood vessel that carries blood away from the heart.Usually is oxygenated and bright redVein – ven/o phleb/oReturn blood to heart.Thinner walls and less elastic than arteries.Have valves to permit blood flow toward the heart and prevent blood from flowing away.CapillariesSingle-cell-thick vessels that connect arterial and venous systems.Blood flow is slower through capillaries than arteries or veins.CRT – Capillary Refill Time – tells us perfusion (or flow through tissues).
8 RESPIRATORY SYSTEMFunction – Brings oxygen from the air into the body for delivery via the blood to the cells.
9 Upper Respiratory System Nose – rhin/oSinus (air filled or fluid filled space…provide mucus, make bone lighter and help produce sound) – sinus/oPharynx (throat) – pharyng/oLarynx (voice box) – laryng/oGlottis – (vocal apparatus) – glott/o’Epiglottis – (acts as a lid – covers the larynx during swallowing) – epiglott/o
10 Lower Respiratory System Trachea (windpipe) - trache/oHas C shape cartinlaginous rings.Bronchi (bottom of the trachea) – bronch/oAlveoli (air sacs in which most of the gas exchange occurs) – alveol/oThorax (Cavity contained within the ribs) – thorac/o and –thoraxRibs – cost/oIntercostal – between the ribsLungs (main organ of respiration) pneum/o pneumon/o and pneu all mean lungs or air. Pulm/o and pulmon/o mean lung.Pleura (membranous sac which encases the lungs) – pleur/o
11 Diaphram (muscle and contraction of the diaphram causes air pressure in the lungs to drop below atmospheric pressure. This produces a vacuum in the thoracic cavity to draw in air) diaphragmat/o phren/oBreathingInhalation – Drawing in of breathExhalation – Release of breathSpir/o – breath or breathing-pnea – breathingApnea – Absence of breathingDyspnea – Difficult or labored breathing
