(a) The oscilation in the pressure inside arteries and arterioles is called by the cardiac rythm. During ventricular systole the pressure rises and during ventricular diastole it decreases

(b)Because when referring to capliaries there is a smaller diameter in the cross section but the surface is bigger. This means that the pressure decreases and the blood has a steady flow instead of periodic bursts.

What components of a tossed salad will pass through the human digestive tract and be digested the least?
DochEvi [55]

Answer:

Cellulose (in the lettuce)

Explanation:

  • A tossed salad usually consists of many vegetables such as lettuce, onions, tomatoes, cucumbers, etc. and then, these vegetables have added dressings which can be of different types.
  • When a person eats a tossed salad then the lettuce will be least digested as it is composed mainly of cellulose and the human body is incapable of digesting cellulose.
  • The inability to digest cellulose by human beings is because there are beta acetal linkages present in the cellulose and human beings lack the enzymes that can break the linkage.
  • However, the undigested cellulose aids in the process of digestion as it acts like fiber and thus, the process of digestion can take place smoothly.
  • Thus, the intake of cellulose-rich foods is also essential.

How might the digestive system and the immune system interact to help protect the body?
padilas [110]

Answer:

Explanation:

The immune system is there to develop a strong answer for infections and diseases that can occur in the body. The system is comprised also of gastrointestinal immune cells. These cells secrete lymphocytes that are there to attack whatever is attacking our body. The gut immune cells and the microflora located inside it are responsible for preventing the growth of other microbes that are bad for us in the gut and to fight ingested pathogens that we can get on our food.
