Answer:
Ximena's mom returned with the lab report of her blood lipid profile. Her HDL cholesterol was low and her LDL cholesterol levels were high. The doctor asked her to look closely at her diet. He asked her to increase unsaturated fats and to decrease saturated fats in her diet
Explanation:
Lipids are the most diverse range of compounds that are nonpolar in nature. The lipids are components of the cell membranes. They are formed of fatty acids, glycerol and a phosphate group. In the fatty acids of the unsaturated fats, there are the presence of double bonds. However, in case of the saturated fats, the double bonds are absent. Such fats are saturated with hydrogens atoms. A type of lipid that play important roles in the body is cholesterol.
There are two types of lipoprotein that carry cholesterol in blood. The HDL or high density lipoprotein is termed as good cholesterol, as it carries the cholesterol back to the liver to eliminate it from the body. LDL or low density lipoprotein is the bad cholesterol, as it carries cholesterol and accumulates it in the arteries to form plaques. A lipid profile is a routine blood test that assess the levels of HDL and LDL in blood. Increase in unsaturated fat causes rise in HDL, that is good for cardiovascular health.

Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
<em>Pulmonary surfactant.</em>
Explanation:
It is essential for life as it lines the alveoli to lower surface tension, thereby preventing atelectasis (a complete or partial collapse of the entire lung or area (lobe) of the lung) during breathing.
