Muscle bundles are coverd in endomysium
Answer:The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart. The term pulmonary circulation is readily paired and contrasted with the systemic circulation.
Placenta abruptio placentae is the premature separation of the placenta from the uterine walls, therefore, limiting the blood and oxygen supply to the fetus. A mother who has a history of abruptio placentae in her previous pregnancy and a severe trauma or blow to the abdomen are at high risk of having partial abruptio placenta. We could not prevent this, however, here are nursing interventions to avoid it:
1. If the mother has a history of abruptio placentae during her previous pregnancy, she must inform her ob-gyn.
2. Avoid any strenuous activities, if possible. When riding a car, always wear your seatbelt.
3. Avoid taking in drugs, cocaine, cigarettes during pregnancy.
We are given
b = 0.22 m^0.87
db/dt = 0.24 g/day at b = 23 g
where
b is the brain mass of the fetus
m is the total mass of the fetus
db/dt is the rate of change of the brain mass of the fetus
We are asked to get the rate of change of the total mass of the fetus
First, we take the first derivative of the given equation with respect to time
db/dt = 0.22 (0.87) m^(0.87-1) dm/dt
Next, simplify and substitute the given values. So,
0.24 g/day = 0.22(0.87)(23)^(0.87 -1 ) dm/dt
Solving for dm/dt
dm/dt = 1.88 g/day
The rate of change of mass of the fetus is 1.88 g/day.
