Summary Introduction

To determine:

The correct occurrence of sequences if semilunar valves are open

(a) 2, 3, 5, 6, (b) 1, 2, 3, 7, (c) 1, 3, 5, 6, (d) 2, 4, 5, 7

(1) coronary arteries fill

(2) AV valves are closed

(3) ventricles are in systole

(4) ventricles are in diastole

(5) blood enters aorta

(6) blood enters pulmonary arteries

(7) atria contract

Expert Solution & Answer

Answer to Problem 1RQ

Solution:

(a) 2, 3, 5, 6: The events that occur when the semilunar valves are open are listed as follows:

1. The closing of atrioventricular valves.

2. The ventricles are in the systolic stage.

3. The blood enters the aorta.

4. The blood enters the pulmonary arteries.

Explanation of Solution

The semilunar valve is situated between the left ventricle and aorta of the heart. The opening of the semilunar valves marks the systolic stage. The atrioventricular valves at this stage are closed in order to prevent the backflow of the blood. The blood is pumped to the aorta and the pulmonary artery to distribute it to the different parts of the body.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
