What systems supply food and oxygen needed for respiration?
A.) digestive, excretory, and cardiovascular
B.) excretory, digestive, and respiratory
C.) digestive, respiratory, cardiovascular
D.) excretory, respiratory, and cardiovascular
Yes I its C.
C.) digestive, respiratory, cardiovascular
They work together like a well-coordinated food delivery service. The digestive system breaks down food into nutrients, the respiratory system brings in oxygen, and the cardiovascular system transports everything to where it's needed. So, it's teamwork that keeps you breathing and your tummy happy!
C.) digestive, respiratory, cardiovascular
To determine the correct answer, let's analyze the question and break down the functions of each system.
The question asks which systems supply food and oxygen needed for respiration. Respiration refers to the process of obtaining oxygen from the environment and using it to produce energy (in the form of ATP) while also eliminating carbon dioxide.
1. The digestive system is responsible for breaking down food into nutrients that can be absorbed by the body. It mainly functions in the process of digestion and absorption, not necessarily in respiration.
2. The excretory system is responsible for eliminating waste products, such as excess water, salts, and nitrogenous wastes (like urea or ammonia). While the excretory system plays a role in maintaining homeostasis, it is not directly involved in respiration.
3. The respiratory system is primarily in charge of the exchange of gases, specifically oxygen and carbon dioxide. It brings in oxygen from the environment and removes carbon dioxide from the body. Thus, it directly contributes to respiration.
4. The cardiovascular system, also known as the circulatory system, includes the heart, blood vessels, and blood. This system transports oxygen, nutrients, hormones, and waste products throughout the body. It plays a crucial role in distributing oxygen from the respiratory system to various tissues for respiration.
Now let's match these functions to the given options:
A.) digestive, excretory, and cardiovascular
B.) excretory, digestive, and respiratory
C.) digestive, respiratory, cardiovascular
D.) excretory, respiratory, and cardiovascular
Option A is incorrect because while the digestive system provides nutrients, the excretory system eliminates waste, and the cardiovascular system transports substances, none of these systems directly supply oxygen for respiration.
Option B is incorrect because although the respiratory system is involved in respiration, the digestive system primarily provides nutrients, and the excretory system eliminates waste. It is important to note that respiration involves the exchange of gases, not the elimination of waste products.
Option C is the correct answer because it includes the respiratory system, which is directly responsible for supplying oxygen for respiration. Additionally, the digestive system provides nutrients from food, and the cardiovascular system transports these nutrients and oxygen to the body's tissues.
Option D is incorrect as it does not include the digestive system, which supplies the necessary nutrients for respiration.
Therefore, the correct answer is C.) digestive, respiratory, cardiovascular.
