Arteries and Arterioles - carry oxygenated blood to the cells 1 of 28 Match. Veins and venules - transport deoxygenated blood away from the cells 2 of 28 Match. Capillaries - connect the arteries and the veins 3 of 28 (Structure of Blood Vessles) The structure of a blood cell is variable depending on function but how many layers does each cell wall have? 3 4 of 28 (Structure of Blood Vessles) Match. Tunica intima - inner layer. Single layer of flattened epithelial cells which lie on a basement membrane, contains connective and elastic tissue 5 of 28 (Structure of Blood Vessles) Match. Tunica media - middle layer made mainly of smooth muscle and elastic tissue 6 of 28 (Structure of Blood Vessles) Match. Tunica adventitia - outer layer made of fibrous connective tissue, collagen and fibroblasts 7 of 28 There is an Increased load on maternal cardiovascular system from the growing fetus, how does the heart adapt to this? It increases in size and changed position 8 of 28 Match. Stoke volume - vol of blood leaving the ventricles after contraction of heart 9 of 28 Stoke volume increases progressively during the BLANK and BLANK trimester to about BLANK more than in the non pregnant state. 1st, 2nd, 30% 10 of 28 Match. Cardiac Output - stroke volume x no. of BPH (beats per min) 11 of 28 Cardiac output increases by up to BLANK 40% 12 of 28 Blood vessels increase in number to supply the placental bed 13 of 28 Cardiac output is estimated to increase by BLANK by BLANK 50%, 8 weeks 14 of 28 Increased stroke volume during pregnancy peaks between BLANK 16 – 24 weeks 15 of 28 The heart rate (BMP) can increase to as much as BLANK by BLANK during pregnancy +10-20% by 32 weeks = +10 to 20bpm 16 of 28 During what trimester, can what position, cause the cardiac output to decrease by what amount. 3rd trimester, supine, 20-30% 17 of 28 Compression of the BLANK can cause BLANK Inferior Vena Cava, Supine Hypotension 18 of 28 In pregnancy, blood volume can increase up to... 50% 19 of 28 In the 2nd and 3rd trimester, the number of red blood cells increase by... 20 - 30% 20 of 28 Haemoglobin is a protein in your red blood cells 21 of 28 Vasodilation occur due to the action of BLANK on smooth muscle of vessel walls Progesterone 22 of 28 Vasodilation is the widening of red blood cells which decreases blood pressure 23 of 28 Blood flow to the uterus is increased from BLANK at the end of the 1st trimester to BLANK at term to aid oxygenation of the fetus via the placenta. 100ml/min , 500mls/min 24 of 28 Match. Normal Pregnancy: little change in systolic BP but diastolic falls, (lowest mid-pregnancy) then rises to approx. pre-pregnancy at term. 25 of 28 Match. Multipara pregnancy: both systolic and diastolic BP decrease. 26 of 28 Match. Geriatric Pregnancy: systolic BP remains constant but diastolic BP increases. 27 of 28 During pregnancy there is a decrease in immunoglobulin’s IgA IgG and IgM 28 of 28
