1. What would happen if there was a hole between the right side of the heart and the left side? What would this be called?

2. What causes blood to flow from one chamber or vessel to another?

3. What happens to the pressure inside a chamber when the myocardium contracts?

Expert Solution

Ans-1. If there is a hole between the right side and left side of heart i.e. between right atrium and left atrium it will lead to flow of oxygenated blood from the left atrium to the right atrium. Similarly if the hole is between right and left ventricles it will lead to flow of blood from left ventricle to right ventricle. Here the blood will mix with deoxygenated blood. It will cause right atrium to enlarge it right ventricle to enlarge in second case and also the amount of blood reaching the lungs will also increase.

The term for this defect is called atrial septal defect (ASD) if hole is between the two atrium and ventricular septal defect (VSD) if hole is between two ventricles.

Ans-2. The flow of blood between the two chambers or between the vessels is due to the pressure difference as the blood flow is from high pressure to low pressure. Various factors affect this blood flow and blood pressure like cardiac output, compliance, volume and viscosity of the blood, blood vessel length and diameter, etc.

Ans-3. When the myocardium contracts, the pressure inside that chamber increases. Due to the contraction of myocardium or walls of the heart, the volume per area is decreased which eventually increases the pressure on that area by blood.

What would the heart have to do to compensate for a hole between the two ventricles?

Normally after birth, the blood entering the right side of the heart (right atrium) is low in oxygen, while the blood leaving the left side of the heart and entering the body’s main circulation (the aorta) is high in oxygen. However, sometimes the foramen ovale fails to close after birth. What effect will this have on the level of oxygen in the blood that leaves the heart to enter into the aorta? Fully explain why.

One "extreme" example of gravity is a black hole. What would happen to the Earth's orbit if the Sun was suddenly replaced by a black hole of the same mass? Why? (Please ignore any processes that the Earth would experience during the formation of the black hole.) Please break it down for us dummies

Describe, in detail, what would happen if you fell into a black hole, from both your perspective, and the perspective of someone who is watching you fall in. You should include specific effects, including effects on space, time, and what you would see.

Some infants are born with a hole in the septum between the left and right ventricles called a VSD (ventricular septal defect). This enables blood to pass between the two ventricles. Considering that blood will always move from an area of higher pressure to an area of lower pressure, which of the following would be a consequence of this condition? (Note, consider these based solely on the condition, and not any subsequent compensatory mechanisms such as an increase in blood...
