How does the cardiovascular system interact with the respiratory system?

Question

A. Blood helps the brain interpret different smells.
B. Blood helps the lungs to inflate and deflate to breathe.
C. Blood transports oxygen from the lungs to other organs.
D. Blood transports nutrients from the stomach to other organs

Answer 1

The correct answer is C. Blood transports oxygen from the lungs to other organs.

The cardiovascular system (which includes the heart and blood vessels) works closely with the respiratory system to deliver oxygen from the lungs to the rest of the body. When we breathe, oxygen enters the lungs and is transferred to the blood, which then circulates it to tissues and organs throughout the body.

Answer 2

Cells contain a certain structure that acts as a gatekeeper in order to maintain homeostasis. This gatekeeper controls what is able to enter and exit the cell. Plant cells produce oxygen as a wast product. What cell structure allows oxygen to pass into the environment?
A. chloroplast
B. vacuole
C. endoplasmic reticulum
D. cell membrane

Answer 3

The correct answer is D. cell membrane.

The cell membrane, also known as the plasma membrane, acts as a gatekeeper for the cell. It regulates what enters and exits the cell, including allowing oxygen, which is produced as a waste product by plant cells during photosynthesis, to pass into the environment.

Answer 4

in the diagram below, structure A is labeled in two different types of cells. Which statement gives the best description of structure A?
A. it helps regulate what enters and exits both cells
B. it helps absorb sunlight for both cells.
C. it converts chemical energy into usable energy for both cells
D. it contains the DNA for both cells

Answer 5

Based on your description, the best answer for structure A is:

A. it helps regulate what enters and exits both cells.

This suggests that structure A is likely the cell membrane, which is responsible for controlling the movement of substances in and out of the cell, providing a selective barrier for both types of cells.

Answer 6

The digestive system includes groups of tissues that absorb nutrients from food that has already been broken. What is the best way to classify this group of tissues?
A.an organelle
B. an organ system
C. an organ
D. an individual organism

Answer 7

The best way to classify this group of tissues is:

B. an organ system.

The digestive system is made up of multiple organs working together to perform the function of digesting food and absorbing nutrients. It includes organs such as the stomach, intestines, liver, and pancreas, all of which contribute to the overall digestive process.

Answer 8

the diagram shows a plant cell which statement best describes the organelle labeled X
a. the ribosome creates proteins for the cell
b. the mitochondrion creates energy for the cell
c. the nucleus stores most of the genetic information for the cell
d. the nucleus controls everything that enters and exits the cells

Answer 9

The best description of the organelle labeled X, if it is the nucleus, is:

C. the nucleus stores most of the genetic information for the cell.

While the nucleus does have a role in controlling many cellular functions (including regulating what enters and exits the nucleus), its primary function is to store the cell's genetic material (DNA). If you are confirming the identity of organelle X, this would be the correct choice if it is indeed the nucleus.

Answer 10

micheal almost gets into a car accident in his car. how does his organ systems respond to this event
a. all of his organ systems stop working.
b. his heart beats faster and his breathing rate increases
c. his respiration rate slows down
d. all of his neurons become paralyzed for ten seconds

Answer 11

The correct answer is:

B. his heart beats faster and his breathing rate increases.

In a stressful situation, such as almost getting into a car accident, the body activates the "fight or flight" response. This response is part of the sympathetic nervous system, which prepares the body to react to a perceived threat. As a result, Michael's heart rate would increase to pump more blood and oxygen to his muscles, and his breathing rate would also increase to supply more oxygen to his body.
