Embolism Vs. Thrombosis
|
Embolism: traveling clot
Thrombosis: clot that blocks flow of blood |
|
|
Blood Antigens
ABO System |
A: A self-antigens anti-B type antibodies
B:B self-antigens anti-A type antibodies AB blood-type A and type B self-antigens no anti-A or anti-B antibodies in plasma O blood-no type A or type B self-antigens both anti-A and anti-B antibodies in plasma Self antigen = in RBC, antibodies = in plasma |
|
|
Capillaries Layers
|
microscopic vessels :Only layer is the tunica intima
|
|
|
Hepatic Portal Circulation
|
blood route through the liver
Carries blood from abdominal organs to liver Superior mesenteric vein, Splenic vein, Gastric, pancreatic, inferior mesenteric veins Vein (hepatic portal vein) exists between two capillary beds Assists with homeostasis of blood glucose levels |
|
|
Angina Pectoris
|
chest pain caused by inadequate oxygen to the heart
|
|
|
RH FACTOR
|
Antigen that we test for
Rh-positive blood: Rh factor antigen present in RBCs Rh-negative blood: no Rh factor present in RBCs; no anti-Rh antibodies present naturally in plasma anti-Rh antibodies, however, appear in the plasma of Rh-negative persons if Rh-positive RBCs have been introduced into their bodies |
|
|
HEART ATTACK
|
Myocardial infarction (heart attack): Blockage of blood flow through the coronary arteries.
|
|
|
LONGEST VEIN
|
Saphenous Vein
|
|
|
TYPES OF LEUKOCYTES
|
Granular Leukocytes: Granules in their cytoplasm can be stained (PHILS)
Neutrophils-carry out phagocytosis in tissues, forms pus at site of infection (60%) Eosinophils-protect against parasitic irritants that cause allergies, inflammatory response (3%) Basophils-produce heparin, which inhibits clotting; part of inflammatory response (1%) Nongranular Leukocytes: Lack visible cytoplasmic granules Lymphocytes-produce antibodies (B-lymphocytes) or directly attack foreign cells (T-lymphocytes) (30%) Monocytes-become macrophages for phagocytosis in tissues (6%) |
|
|
PULSE SITES
|
Superficial temporal artery, Facial artery, Carotid artery, Axillary artery ,Brachial artery,Radial artery, Femoral artery, Popliteal artery and Dorsalis pedis
|
|
|
CENTRIFUGE
|
centrifuge is used to separate a whole blood into formed elements and liquid fraction.
|
|
|
WHICH CHAMBER OF HEART IS MORE MUSCULAR?
|
The left ventricle, being responsible for pumping the blood through the systemic circulation, generates the highest pressures. For this reason, the left ventricle has the thickest muscular walls
|
|
|
BLOOD VESSEL VALVES
|
Tissue that prevents the blood from flowing backwards
|
|
|
OSMOTIC PRESSURE
|
Substances maintain osmotic pressure to regulate fluid in tissues
Albumin – regulates osmotic pressure Osmotic Pressure Draws Materials into capillaries |
|
|
IMMATURE NEUTROPHILS
|
Bands
|
|
|
ATRIAL SYSTOLE
VENTRICLE SYSTOLE |
Contraction of Systole, Contraction of ventricles
|
|
|
WHAT TISSUE IS BLOOD?
|
LIQUID CONNECTIVE TISSUE
|
|
|
BLOOD SUPPLY TO INTESTINE
|
Branches of Aorta
Coeliac artery Superior mesenteric artery Inferior mesenteric artery |
|
|
THROMBOCYTOPENIA
|
• Platelet deficiency
• Even normal movements can cause bleeding from small blood vessels that require platelets for clotting |
|
|
ERYTHROBLASTOSIS FETALIS
|
Erythroblastosis fetalis develops in an unborn infant when the mother and baby have different blood types or RH factors. The mother produces substances called antibodies that attack the developing baby's red blood cells.
|
|
|
BLOOD DONATION:AUTOLOGOUS
HEMAPHARESIS,PLASMAPHARESIS, WHOLE BLOOD AND PLASMA |
Autologous: donate patients own blood
Hemapharesis: keep desired elements and return rest to donor Plasmapheresis: keep plasma and return rest to donor Whole blood: loss of large volume of blood Plasma: replace blood volume |
|
|
BLOOD SUPPLY TO HEART MUSCLE
|
Right and Left Coronary arteries
Left CA: Divides into LAD : supply front of heart Cx: Back of heart Left Coronary Artery: Divides into PDA and Marginal Branch |
|
|
ARTHREOSLEROSIS
|
• Atherosclerosis: Accumulation of yellowish plaques of cholesterol, other lipids, and cellular debris in the inner layers of the walls of arteries
|
|
|
ANASTOMOSES
|
Connection of two structures. It refers to connections/ communication between blood vessels
Examples Circle of Willis: circle of arteries that supplies the brain • Superficial palmar arch: located in hand • Mesenteric arches • Arterial arches |
|
|
VENOUS SINUSES
|
Spaces between the endosteal and meningeal layers of the dura. They contain venous blood that originates for the most part from the brain or cranial cavity.
|
|
|
PULMONARY CIRCULATION
|
Pulmonary circulation
• Carries blood to and from the lungs;arteries deliver deoxygenated blood to the lungs for gas exchange • Path goes from right ventricle through pulmonary arteries, lungs, pulmonary veins, to left atrium |
|
|
SYSTEMIC CIRCULATION
|
Systemic circulation
• Carries blood throughout the body • Path goes from left ventricle through aorta, smaller arteries, arterioles, capillaries, venules, venae cavae, to right atrium |
|
|
BARORECEPTORS
|
Baroreceptors: pressure receptors in aorta and carotid arterie that detect BP changes
|
