On the hierarchy ladder of body systems, after the tissue rung the next rung is composed of structures made up of two or more types of tissue that perform a specific function of the body, like the heart, lungs, liver, brain, bladder, stomach, kidneys, and so on. What term BEST describes this rung on the ladder?
Responses:
a) cells
b) organs
c) ribosomes
d) mitochondria
b) organs
b) organs
The correct term that best describes the rung on the ladder composed of structures made up of two or more types of tissue that perform a specific function of the body is **b) organs**.
To arrive at this answer, let's break down the given options and their definitions:
a) Cells: Cells are the basic building blocks of all living organisms. While they are crucial for the overall function and structure of the body, they are not specifically referring to the next rung on the ladder after tissues.
b) Organs: Organs are composed of two or more types of tissues that work together to perform specific functions in the body. Examples given, such as the heart, lungs, liver, brain, bladder, stomach, and kidneys, all fall under the category of organs. The multiple tissues within an organ collaborate to carry out specialized tasks necessary for the body.
c) Ribosomes: Ribosomes are small structures within cells that are responsible for protein synthesis. While they are essential for cellular functions, they do not represent the next rung on the hierarchy ladder after tissues.
d) Mitochondria: Mitochondria are organelles found in the cells that perform the vital task of producing energy. Similar to ribosomes, they play a significant role within cells specifically, but they are not representative of the rung after tissues.
Considering the definitions and comparing them to the provided options, the term that best fits the rung on the ladder composed of structures made up of two or more types of tissue performing specific functions is **organs (option b)**.
