<span>In the right atrium, the auricle and anterior wall exhibit obvious muscular ridges called MUSCULI PECTINATI.

Musculi pectinati or pectinate muscles are identified as specialized intracardiac muscle. The muscular ridges are like combs. These ridges help the right atrium dilate without much walls stress during adverse loading conditions.</span>

Artyom0805 [142]

Answer:

An organism would need a 4 chambered heart.

Explanation:

The heart consists of 4 chambers in which blood flows freely.  Right atrium, left atrium, left ventricle and right ventricle.

The pulmonary arteries carry de-oxygenated blood to the lungs  from where CO2 is released and O2 is picked up during the process of respiration. The pulmonary vein then takes the oxygenated blood to the left atrium of the heart and then to the left ventricle of the heart.

(a) (1 pt) Assume diastolic blood pressure is normally distributed in a certain population, with a mean of 82 mmHg and a standar
Natali [406]

Answer:

2.275% of this population has a diastolic blood pressure less than 60 mmHg

Explanation:

Hello!

Yo have the distribution of the diastolic blood pressure in a certain population. Be X: diastolic blood pressure of an individual, X~N(μ;δ²)

Where

μ= 82mmHg

δ=11 mmHg

You need to calculate the probability of an individual of this population having less than 60mmHg diastolic blood pressure.

Symbolically:

P(X<60)

To obtain the value of probability you need to standardize the value of diastolic pressure so that you can obtain it from the standard normal distribution. The way to standardize the value is to subtract the mean and divide by the standard deviation

Z= (X-μ)/δ~N(0;1)

P(Z<(60-82)/11)

P(Z<-2)= 0.02275

I hope it helps!
