Answer:
The correct answer is A. In early fetal life.
Explanation:
Oogenesis is the process of formation of female gametes in the reproductive organ called ovary. In females oogenesis process starts even before the birth of the female. It starts in fetal stage when primordial germ cells moves from yolk cells to ovaries.
These germ cells are diploid and increase in number to millions by dividing mitotically. Developed germ cells called primary oocytes and during fetal stage they enters in meiosis I and gets arrested in the prophase I stage of meiosis I. This phase is then completed after the puberty takes place.
Coinsurance is the correct answer

1.
Valves open in response to _________________ on their two sides.
Blood pressure
2.
List the chambers/ vessels that the four valves connect:
______(1)______ Pulmonary semilunar ______(2)_____
______(3)______ Aortic semilunar ______(4)_____
______(5)______ Mitral ______(6)_____
______(7)______ Tricuspid ______(8)_____
1. R. ventricle
2. Pulmonary artery
3. L. ventricle
4. Aorta
5. L. atrium
6. Pulmonary vein
7. R. atrium
8. Inferior/superior vena cava
3.
a. Ventricular filling occurs during______ ventricular_________.
b. Blood flows through the _______ or __________ valves into the ventricles.
1. Mid-late
2. Diastole
3. Mitral
4. Tricuspid
4.
During Ventricular systole, what closes the AV valves?
Intraventricular pressure rising and causing ventricular contractions.
5.
During ventricular systole, what opens the semilunar valves?
Ventricles contract, raising pressure, bblood pressure then forces the semilunar valves open.
6.
During Isovolumetric relaxation, what closes the semilunar valves?
When blood pressure in the artery exceeds the blood pressure in the ventricle.
7.
During Isovolumetric relaxation, what opens the AV valves?
When blood pressure in the ventricle exceeds the blood pressure in the arteries.
8.
Why is hypertension hard on the heart?
Beacuse overtime high blood pressure causes heart muscles to thicken, which means more work to pump blood through vessels. It can cause heart disease because of heart constantly overworking.
9.
Looking at the ventricular volume graph, the stroke volume is approximately how many ml?
70ml
10.
During the four phases listed below, state whether the AV and semilunar valves are opened or closed:
1. Ventricular Filling
2. Isovolumetric
3. Ventricular Ejection
4. Isovolumetric
1. AV: Opened, Semilunar: Closed
2. AV: Closed, Semilunar: Closed
3. AV: Closed, Semilunar: Opened
4. AV: Closed, Semilunar: Closed”
Answer: The gastrocnemius produces a fast movement of motion in the calf area of the leg.
Explanation:
Osteoporosis is a bone disorder that affects the structure of the bones and their hardness. The risk factor for Osteoporosis can be avoided by intaking a diet rich in calcium and vitamin D.
<h3>What is Osteoporosis?</h3>
Osteoporosis is the disease of the skeletal system that weakens the bones and makes them susceptible to breaking by becoming brittle. The bones in the diseases become very fragile that even a small stress condition can lead to bone fracture.
As one ages the level of calcium and vitamin D produced in the body gets depleted and as a result, the bones become weak and porous. The level of these elements must be balanced by the external food in the diet.
The nurse should provide information to the older adults on Osteoporosis by educating them on the dietary intakes that are rich in vitamin D and calcium. The intake of sodas must be reduced as they are rich in phosphorous that weakens the bones.
Therefore, dietary information must be given to the person to reduce the chances of Osteoporosis.
