Answer: Fibrous pericardium and Serous Pericardium
Explanation:
The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.
Fibrous pericardium
This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.
Serous pericardium
This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.
Answer: the "y=mx+b" form (called the slope-intercept form of the equation of a line).
Explanation: Finding the equation for a line is a common problem in geometry and trigonometry. There are two common situations where you are asked to find the equation for a line: either you'll be provided with one point on the line and the slope of the line, or you'll be provided two points on the line.
The "b" value (called the y-intercept) is where the line crosses the y-axis.
So point (x1, y1) is actually at (0, b)
and the equation becomes:
Start with
y − y1 = m(x − x1)
(x1, y1) is actually (0, b):
y − b = m(x − 0)
Which is:
y − b = mx
Put b on other side:
y = mx + b
Answer:
The most likely diagnosis would be ulcerative colitis, given the patient's history of regional enteritis and the finding of dark blood at the level of the sigmoidoscope.
