The lymphatic system
a. removes excess fluid from tissues.
b. absorbs lipids from the digestive tract.
c. defends the body against microorganisms and other foreign substances.
d. All of these are correct.

Introduction:
The lymphatic vessels are one of the most important and essential components of the lymphatic system. The lymphatic system of the body comprises cells, tissues, and organs.
Answer to Problem 1RAC
The correct answer is option (d) All of these are correct.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) All of these are correct. The lymphatic system helps in the removal of excess fluid from the tissues and also absorbs lipids from the digestive tracts with the help of lacteals. The lymphatic system is responsible for providing immunity by providing defense against foreign substances and microorganisms. Hence, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) removes excess fluid from tissues. The lymphatic system helps in the removal of excess fluid from tissues of the body, but it also absorbs lipids from the digestive tracts and provides defense against foreign substances and microorganisms. So, this is an incorrect answer.
Option (b) absorbs lipids from the digestive tract. The lymphatic system helps in absorbing lipids with the help of lacteals, but it also helps in the removal of excess fluid from tissues of the body and provides defense against foreign substances and microorganisms. So, this is an incorrect answer.
Option (c) defends the body against microorganisms and other foreign substances. The lymphatic system defends the body against microorganisms and other foreign substances, but it also plays an important role in removing excess fluids and absorbing lipids from the digestive tract. So, this is an incorrect answer.
The lymphatic system plays an important role in removing excess fluids and absorbing lipids from the digestive tract, and also provide defense against invasive pathogens. Hence, the correct answer is option (d) All of these are correct.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.
