Homework Answers
# When heart beats two phases occur Diastole and Systole
1st phase( Diastole )- heart relaxes and the atria fills with blood, atrioventricular valve opens and blood flows from atria to ventricles
2nd phase( Systole)- heart contracts ,atria contracts and forces more blood to ventricles and pumps out blood into the whole body .
# The pathway of blood through heart and lungs starts from :-
- Right atrium to right ventricle,
- From right ventricle to lungs through pulmonary artery ,then from lungs to left atrium through pulmonary veins
- And then from left atrium to left ventricle
- From left ventricle to the whole body through aorta

Question 31 1.6 pts What is the correct sequence for the blood circulation through the cardiovascular system? I-Blood is pumped from the heart into the arterial system, blood flows from the larger arteries into the fine arterioles. II-Blood flows into the venules and from there into the larger veins, from there the blood returns to the heart Il-Blood is delivered into the thinnest and most numerous capillaries, where exchanges with the tissues occur. IV-Blood flows into the peritoneal portal system...

After traveling through the body, blood flows into the main (M) pulmonary artery, which splits into the right (R) and left (L) pulmonary arteries to get oxygenated in the lungs. Assume the process is continuous and steady-state. Density (rho) of blood = 1.06 g/cm^3 Diameters (D): D_M = 2.95 cm; D_R = 1.98 cm; D_L = 2.21 cm Velocities (V): V_M = 10 cm/s; V_R = 8 cm/s a. If the relationship between flow velocity (V), cross-sectional area (A) and...
