BP = CO x PR
This means that blood pressure is influenced by these two factors.
Cardiac output also has an equation:
CO = HR x SV
where:
If you combine the two equations,
BP = HR x SV x PR
So there are 3 factors that operate in increasing the BP:

In human physiology, the two major cations (positively charged ions) are Na (sodium) and K (potassium) ions. They directly affect the normal functioning of all cells. Na is the main cation in the extracellular fluid (nasa labas ng cells, meaning nasa dugo, in-between ng cells, basta wala sa loob ng cells). K is (nahulaan nyo na siguro) the main cation inside the cells. And when we talk of these ions, we are concerned about electrolyte balance (narinig nyo na siguro ito pag me diarrhea kayo at kelangan nyo ng oresol).
From Martini's Anatomy and Physiology:
The total amount of sodium in the ECF represents a balance between two factors:
- Sodium ion uptake across the digestive epithelium. Sodium ions enter the ECF by crossing the digestive epithelium through diffusion and carrier-mediated transport. The rate of absorption varies directly with the amount of sodium in the diet.
- Sodium ion excretion at the kidneys and other sites. Sodium losses occur primarily by excretion in urine and through perspiration. The kidneys are the most important sites of Na+ regulation. (Kaya bawal din ang maalat sa me sakit sa bato.)
A person in sodium balance typically gains and loses 48–144 mEq (1.1–3.3 g) of Na+ each day. When sodium gains exceed sodium losses, the total Na+ content of the ECF goes up; when losses exceed gains, the Na+ content declines. However, a change in the Na+ content of the ECF does not produce a change in the Na+ concentration. When sodium intake or output changes, a corresponding gain or loss of water tends to keep the Na+ concentration constant. For example, if you eat a very salty meal, the osmotic concentration of your ECF will not increase. When sodium ions are pumped across your digestive epithelium, the solute concentration in that portion of the ECF increases, whereas that of the intestinal contents decreases. Osmosis then occurs. Additional water enters the ECF from the digestive tract, elevating blood volume and blood pressure. Thus, persons with high blood pressure are advised to restrict the amount of salt in their diets.
Ngayon, hindi lang "maalat" ang equivalent ng "restrict the salt intake". In particular, pay attention to the sodium content of your food. Gaya ng MSG (monosodium glutamate), peanut butter, etc. To see a list of sodium-rich foods, click here.

It has dawned on me how people who live in areas where the summers are short and winters long have mastered the methods of food processing and preserving...from berries (which would have been of little value to Pinoys if they were native berries and grew wild, eaten all through the year for free...) to meats. Come to think of it...how many rotten tomatoes and veggies are being thrown away daily in the Philippines?...I have learned to take advantage of the growing season here...and I have learned to make jams and jellies among other things to preserve the produce that I got from my garden.



Strawberries freeze well. You can do so with or without sugar. To freeze strawberries using sugar, mix equal amounts of sugar and water in a saucepan. Stir over medium heat until sugar is dissolved and mixture is clear. Cool the mixture completely. Measure 1 cup (149g) of stemmed and sliced strawberries into a 2-cup-size (473.16ml) freezer bag. Pour 1/2 to 2/3 of a cup (118.3,157.7ml) of the sugar/water mixture into the bag,just enough to completely cover the strawberries. Seal and freeze the bag, keeping berries in a single layer.We consume about 1 small jar in 2-3 days, on Ritz crackers, or PB&J sandwiches, on pancakes, on muffins, and anything that suits us! Hope you too will enjoy your strawberries!
To freeze strawberries without the use of sugar, set whole, firm berries on a cookie sheet, in a single layer and not touching each other, and place in the freezer. After berries are frozen, put them in a sealable plastic bag. This way they are 'individually frozen' and do not stick together.
Because the moisture content of strawberries varies throughout the season, it is recommended that home-frozen strawberries be used in beverages and sauces, not in recipes where liquid variations could make a difference. (Commercially frozen strawberries are consistent in texture and density.)
Thawing strawberries in the refrigerator will allow them to retain their shape better. When thawing at room temperature, keep the berries in a clean, sanitary environment. Cover and refrigerate unused thawed berries within two hours. Never try to speed up the thawing process by running water over the outside of the container, as that allows bacteria to grow. After thawing, keep berries refrigerated and use within three days. Never re-freeze strawberries.
While still attractive, thawed strawberries may be a little darker and lack the sheen that a fresh berry would have.
