1. How does the heart change as it develops in a fetus?
A few weeks after conception, the heart takes up most of the space in the fetus’ midsection. At first the heart is just a tube, but it grows so fast that it starts to take up a lot of space. In order to conserve space, it bends and twists into the commonly known shape. It starts out beating 90 times per minute due to the intense need for oxygen and slows down to 70 beats per minute by the age 18.
2. What is the largest vessel that is attached to the heart, and what does it do?
The largest blood vessel is the aorta. It carries nutrient-rich blood away from the heart so it can be distributed to the rest of the body.
3. What is pulmonary circulation?
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart.
4. The sound you hear when you listen to your heart with a stethoscope is actually what?
The sound you hear through a stethoscope is your valves shutting to prevent blood from flowing the wrong way.
5. Distinguish between systole and diastole phases of the heart.
During the systole phase, the right ventricle is sending blood into the pulmonary artery and the left ventricle is sending blood into the aorta. During the diastole phase, the atria is relaxed and releasing blood into the ventricles.
6. Distinguish between an artery and a vein.
An artery pumps blood away from the heart and a vein moves blood towards the heart.
7. What is a sphygmomanometer?
A sphygmomanometer is an instrument used to measure blood pressure that consists of an inflatable rubber cuff that is applied to the arm to determine systolic and diastolic blood pressure by increasing and gradually releasing the pressure in the cuff.
8. How is hypertension treated?
Hypertension can be treated through blood pressure medication that lowers your blood pressure and through diuretics that help decrease extra fluid in your body. Lifestyle changes that can decrease blood pressure
