Each of the four body systems are listed twice. Match each system to its description as well as its picture showing its major organs.
Human bodies are complex and contain many systems within them. Each of these systems are made of organs that work together to perform a function for human life. Four major systems include respiratory, reproductive, excretory, and circulatory. While each system works independently, they also work together to keep human bodies alive and healthy.
A. This system transports blood through the body and heart.
B. This system brings oxygen into the body and rids the body of waste gases. Some organisms use their skin. This is also a cell-level process.
C. This system relates to the process by which an organism gets rid of its waste.
D. This system relates to the process by which an organism replicates. Sexually reproduction usually involves male cells (sperm) meeting female cells (eggs) to produce a fertilized egg or zygote.
The four major systems listed are the respiratory, reproductive, excretory, and circulatory systems. Each of these systems can be matched with the descriptions provided as follows:
A. This system transports blood through the body and heart.
- Match: Circulatory System
- Picture: Would depict the heart, veins, arteries, capillaries, and possibly the lungs as the site of gas exchange.
B. This system brings oxygen into the body and rids the body of waste gases. Some organisms use their skin. This is also a cell-level process.
- Match: Respiratory System
- Picture: Would show the lungs, trachea, bronchi, and possibly the nose and mouth as entry points for air.
C. This system relates to the process by which an organism gets rid of its waste.
- Match: Excretory System
- Picture: Would include the kidneys, ureters, bladder, and urethra, which work together to filter blood and remove urine from the body.
D. This system relates to the process by which an organism replicates. Sexually reproduction usually involves male cells (sperm) meeting female cells (eggs) to produce a fertilized egg or zygote.
- Match: Reproductive System
- Picture: Would be different for male and female systems. For males, it would show the testes, vas deferens, prostate, seminal vesicles, and . For females, it would show the ovaries, fallopian tubes, uterus, and .
Unfortunately, without visual images, I'm unable to directly match the descriptions to pictures, but these descriptions should help identify the relevant organs in any images associated with these body systems.
