Stress causes the blood vessels to constrict, also causes the chemical cholesterol into the bloodstream too much of that and you might have a heart attack due to the clogging of vessels
Chyme released from the stomach enters the small intestine, which is the primary digestive organ in the body. Not only is this where most digestion occurs, it is also where practically all absorption occurs. The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone). Since this makes it about five times longer than the large intestine, you might wonder why it is called “small.” In fact, its name derives from its relatively smaller diameter of only about 2.54 cm (1 in), compared with 7.62 cm (3 in) for the large intestine. As we’ll see shortly, in addition to its length, the folds and projections of the lining of the small intestine work to give it an enormous surface area, which is approximately 200 m2, more than 100 times the surface area of your skin. This large surface area is necessary for complex processes of digestion and absorption that occur within it.

<h2>Muscles in legs </h2>
There are three muscles in the human legs. The hamstrings are three muscles which are located at the back of the thigh that affect knee and hip movement. They start under the gluteus maximus behind the hip bone and then attach to the tibia bone at the knee. These are biceps femoris which is the long muscle in the body that flexes the knee.
1. Why are essential proteins so important to a
healthy diet?<span>
Proteins are a “macronutrient” (just like carbohydrates and fat), which means
that your body needs a large amount of them in order to stay healthy. A healthy
diet requires a balance between the macronutrients and the “micronutrients”
(such as vitamins and minerals, which the body needs in smaller amounts). </span>

2. How does the body use protein?<span>
The body uses proteins to: create and repair tissues; build enzymes, chemicals,
and hormones; every cell in your body is in fact made up of proteins; and it is
also the building block of bones, muscles, cartilage, skin, and blood.</span>

3. List at least three features shared by the
various popular diet plans discussed in this section.<span>
Since I don’t know which diet plans you’ve discussed, I’ll just list some the
most common features that most healthy diet plans have in common: a good
balance of nutrients, prefer organic food rather than ready/frozen food filled
with chemicals and preservatives, and add a healthy lifestyle.</span>

<span>4. Name and describe a category of
vegetarianism.
</span><span>A branch of
vegetarianism is Veganism. A vegan does not eat any products that derive from
animals, for example: milk, cheese, butter, eggs, etc. as a step forward to
vegetarianism which simply cuts meat and fish out of the diet. Vegans though
need to replace those nutrients from products that are organic a non-animal-derivate
such as soy, for example. </span>
