Psl 250 when the ventricles are contracting, blood is flowing through which valves?

1 answer:

8 0

Pulmonary valve and Aortic valve

During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery.

<h3>What happen when ventricles contract ?</h3>

When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery

Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.

When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.

I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is

Tt x tt (heterozygous crossed with a homozygous recessive)

The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.

So the percentage of offspring that are homozygous recessive is 50%.
