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.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
