Name the valves of the heart
1)AV Valves: Between atrium & ventricles Tricuspid on the right, Bicuspid (Mitrol) on left 2)Semilunar valves: Between the ventricles & functional vessels Right Ventricle/ Pulmonary Artery, Left ventricle/Aorta
100
Name the feeding vessels?
Coronary Arteries Coronary Veins
100
What is the pathway of the circulation system?
Heart (LV) 1) Arteries 2) Arterioles 3) capillaries 4)Venules 5)Veins Heart (RA)
100
Retrosternal Pain radiating to shoulders, neck, jaw and arms. Lasts 3 to 15 minutes
Angina
100
What are the sign and symptoms of an MI?
1) Retrosternal pain(feels like a vise) possibly radiating to shoulders,neck,jaw,arms with weakness & numbness of hands. 2) occurs suddenly upon rest or effort 3)Feeling of oppression, suffocation or strangling 4) Agitation, Anxiety 5)Hypotension, very weak pulse 6)Fatigue 7)Diaphoresis 8) Nausea, Vomiting
200
Name the parts of the heart wall
1) Endocardium (Inner layer) 2) Myocardium (Middle layer) 3) Epicardium (outer layer)
200
Name the functional vessles
1)Vena Cava 2) Aorta 3) Pulmonary Veins 4) Pulmonary Arteries
200
What are the types of Circulation?
1) Systemic: Greater Circulation 2) Pulmonary: Lesser Circulation 3) Coronary Circulation 4) Lymphatic Circulation 5) Hepatic-Portal Circulation
200
Progressive Dyspnoe, intolerance of heat and exercise, fatigue, vertigo and confusion, cold extremities with Cyanosis, Oliguria, Nycturia, Tachycadia Anxiety, agitation
Heart failure (CHF)
200
What are the sign and symptoms of Varicose veins?
1)Blue knotty veins 2)increasing fatigue in the limb
300
What is the role of the Pericardium (2 layer envelope)?
1)Prevents heart Distension 2)protects the heart 3)Holds the heart in place 4)It lubricates the outer heart layer
300
What are the 3 main layers of vessels?
-Tunica Intima (Internal layer) comes in contact with blood, found in all types of vessels. -Tunica Media (middle layer)contains smooth muscle tissue + elastic tissue innervated by the ANS which enables arterioles to take part in regulating blood flow & maintaining BP. -Tunica Adventitia (external layer):feeds vessel walls, provides irrigation to cells
300
What is the role of the Circulation system?
-Carry oxygen from lungs to the body -carry nutrients to the body (Glucose, lipids....) -Fight diseases and infections - dispose of waste products
300
Hyperthermia, Precordial pain with friction on ausucltation, Dyspnoea, Tachycardia
Pericarditis
300
What are the sign and symptoms of Phlebitis?
1)Redness, induration & heat along affected veins. 2) Pain in calf when the foot is in dorsiflexion 3) localized oedema for a superficial vein & oedema for the limbs for deep vein.
400
What is a cardiac cycle, and what are they?
1 heart beat , Systole:contraction, Diastole: relaxation
400
What are capillaries made up of, and what happens in them?
They are only made of a single layer of endothelium: Intima. this is where the exchange happens of Oxygen,nutrients,carbon dioxide and waste between the blood and cells.
400
All arteries are connected to the Aorta, which emerges from the LV. All veins return blood to the RA via?
-Coronary sinus carries blood from the coronary veins of the heart. -Superior Vena cava carries blood from the veins of 1)Head & neck 2) Upper limbs 3)Certain parts of thorax -Inferior Vena Cava carries blood from the veins of: 1) Certain parts of thorax 2) Abd 3) Pelvis 4)Lower limbs
400
Cyanosis, pallor, pain numbness, cold, marble skin no pulse
Atherosclerosis (Arteriosclerosis)
400
What are the sign and symptoms of Raynaud's diseases?
1)Pain 2) coldness in fingers 3) pallor 4) possible ulceration in the extremities 5) Brittle nails
500
What is the Nervous control of the heart, and what is the roles?
1) Intrinsic (Conduction system): Produce and distribute electrical impulses stimulating heart muscle contraction. -SA node: start each cardiac cycle, and determine the speed of heart rate. -AV node: conducts the impulses to the bundle of his(AV bundle). bundle of his (AV bundle):Conducts impulses to the Purkinje for heart contraction. -Purkinje: Contract the ventricles. Extrinsic(ANS): Sympathetic Fight or flight Parasympathetic Vagus nerve: Vasodilation slows everything down.
500
Role of Lymphatic vessels?
To supply the blood with lymph which contain WBC.
500
What 3 factors influence blood pressure?
1) Cardiac output 2) Blood Volume 3) Peripheral vascular resistance
500
Skin discoloration, itching sometimes pain and muscle cramps, dry,cracked skin, tissue atrophy,Oedema, increased fatigue in the lower limbs
Venous insufficiency
500
What are the sign and symptoms of Acute Pulmonary Oedema?
1) Sudden asphyxia(lack of oxygen) with suffocation feeling. 2)Dyspnoea which worsens 3)cough with mucoid, foamy salmon-coloured sputum. 4)Haemoptysis 5)noisy breathing with moist rails 6)Anxiety, agitation 7)oedema 8)cyanosis of extremities, greyish tinge
