What is the highest level of organization in the human body?
The highest level of organization in the body is the organism level. This is the entirety of a living thing, such as the entire human body.
What are the basic structures of living matter?
Cells are the basic structural units of living matter. Most cells in the human body contain one or more nuclei, which hold the genetic instructions for the cell's structure and function. There are several main functions of cells in the body including absorbing nutrients and converting food into energy through the process of cellular respiration. There are over 200 cell types in the human body. Some examples of cells at the cellular level of organization include:
What is the role of the cardiovascular system?
For example, the job of the cardiovascular system is to pump blood around the body to distribute oxygen and nutrients and remove metabolic waste, such as carbon dioxide. The main organs of the cardiovascular system are the heart, blood, and blood vessels, like arteries, veins, and capillaries. The cardiovascular system is essential for distributing oxygen and nutrients to cells all over the body. Cells require oxygen to make energy. Thus, without the cardiovascular system, there won't be enough oxygen, and thus not enough energy for the cells and they will die. This is what happens during a heart attack. The heart stops working and the body doesn't get oxygen or nutrients and can die.
What is tissue in biology?
Tissue is a biological unit made up of several cells acting in conjunction with each other. What are the four levels of organization in an organism? There are four main types of tissue level of organization in the body:
Why are cells considered basic units of life?
Cells are considered the basic units of life because they are self-sustaining. All cells are capable of making more of themselves through cell division. The information needed for cellular structure and function is coded for in the DNA. In eukaryotic cells, like human cells, DNA is enclosed in an organelle called the nucleus. Cells also have other organelles as well, such as ribosomes for making protein, mitochondria for making energy, the Golgi apparatus for sorting proteins and more. Different cells have different compositions of organelles depending on their job inside the body. For example, cardiomyocytes or heart cells, have lot of mitochondria because they need to make energy to contract and keep the heart beating. Hepatocytes, or liver cells, have lots of smooth endoplasmic reticulum to help the liver detoxify the body.
What are the basic units of life?
Cells are the basic units of life and make up all living things. The human body has many types of cells that are arranged into four distinct tissues. These tissues form organs, which perform a specific job in the body. Organs work together in organ systems, which form an organism.
Which organ is the main organ of the cardiovascular system?
For example, the heart is the main organ of the cardiovascular system. It is made mostly of muscle tissue and acts as a pump. Sending blood to the lungs to get oxygenated and out to the body to deliver that oxygen and important nutrients. The brain is the main organ of the nervous system. It is made of neurons and other connective tissue and is the main processing center for information in the body.
